Simple XML使用小结

作者: Michael 日期: 2012 年 4 月 4 日发表评论 (3) 查看评论

之前曾写过一blog ： XStream序列化JAVA对象为XML以及反序列化（http://www.micmiu.com/lang/java/xstream-java-xml/），今天介绍另一个Java Bean<->XML 之间序列化和反序列化的轻量级工具：Simple

官网：http://simple.sourceforge.net/home.php

截止2011-09-28最新版本（附近可下载）：simple-xml-2.6.1.jar

特点：

jar lib文件只有360K左右的大小
它的使用不需要依赖于其他 JAR 文件
通过注解的方式，灵活方便

下面将分节详细介绍Simple的特点和使用方法：

[一]、简单bean的序列化和反序列化
[二]、自定义节点名称
[三]、嵌套对象
[四]、可选的非强制性的元素或属性
[五]、List<Object>处理
[六]、inline 参数用法
[七]、构造函数的注解处理

[一]、简单bean的序列化和反序列化

1.java bean

package michael.serialization.simplexml;

import java.util.Date;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;

/**
 *
 * @blog http://www.micmiu.com
 * @author Michael
 */
@Root
public class MyTestVo {

    @Element
    private String userName;

    @Attribute
    private String wife;

    @Attribute
    private String realName;

    @Element
    private Date bornDate;

    @Element
    private Double height;

    public String toString() {
        return "MyTestVo : [ userName = " + userName + " , wife = " + wife
                + " , realName = " + realName + " , height = " + height
                + " , bornDate = " + bornDate + " ]";
    }
    //省略set get等方法
    ......

}

package michael.serialization.simplexml;

import java.util.Date;

import org.simpleframework.xml.Attribute;

import org.simpleframework.xml.Element;

import org.simpleframework.xml.Root;

/**

* @blog http://www.micmiu.com

* @author Michael

@Root

public class MyTestVo {

@Element

private String userName;

@Attribute

private String wife;

@Attribute

private String realName;

@Element

private Date bornDate;

@Element

private Double height;

public String toString() {

return "MyTestVo : [ userName = " + userName + " , wife = " + wife

+ " , realName = " + realName + " , height = " + height

+ " , bornDate = " + bornDate + " ]";

}

//省略set get等方法

......

}

2.序列化

public static void main(String[] args) throws Exception {
        String xmlpath = "d:/test/michael/simple_testvo.xml";

        MyTestVo vo = new MyTestVo();
        vo.setUserName("michael");
        vo.setRealName("大大");
        vo.setWife("小小");
        vo.setHeight(173.3d);
        vo.setBornDate(new Date());

        try {
            Serializer serializer = new Persister();
            File result = new File(xmlpath);
            serializer.write(vo, result);
        } catch (Exception e) {
            e.printStackTrace();
        }

}

public static void main(String[] args) throws Exception {

String xmlpath = "d:/test/michael/simple_testvo.xml";

MyTestVo vo = new MyTestVo();

vo.setUserName("michael");

vo.setRealName("大大");

vo.setWife("小小");

vo.setHeight(173.3d);

vo.setBornDate(new Date());

try {

Serializer serializer = new Persister();

File result = new File(xmlpath);

serializer.write(vo, result);

} catch (Exception e) {

e.printStackTrace();

}

序列化成功生成的simple_testvo.xml文件如下：

<myTestVo wife="小小" realName="大大">
   <userName>michael</userName>
   <bornDate>2011-09-28 17:39:59.432 CST</bornDate>
   <height>173.3</height>
</myTestVo>

<userName>michael</userName>

</myTestVo>

ps: 注解可以把Java的属性序列化时指定为属性或者节点元素

3.反序列化

把上述生成的XML文件反序列化成Java bean测试代码：

 public static void main(String[] args) throws Exception {
        String xmlpath = "d:/test/michael/simple_testvo.xml";

        Serializer serializer = new Persister();
        File source = new File(xmlpath);
        try {
            MyTestVo vo = serializer.read(MyTestVo.class, source);
            System.out.println(vo);
        } catch (Exception e) {
            e.printStackTrace();
        }
}

public static void main(String[] args) throws Exception {

String xmlpath = "d:/test/michael/simple_testvo.xml";

Serializer serializer = new Persister();

File source = new File(xmlpath);

try {

MyTestVo vo = serializer.read(MyTestVo.class, source);

System.out.println(vo);

} catch (Exception e) {

e.printStackTrace();

}

如果XML中包括中文字符有可能反序列化时会报错，以utf-8的编码读取XML文件即可，故修改代码如下：

 /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        String xmlpath = "d:/test/michael/simple_testvo.xml";

        Serializer serializer = new Persister();

        try {
            InputStreamReader is = new InputStreamReader(new FileInputStream(
                    xmlpath), "utf-8");
            PropertyList parseVo = serializer.read(PropertyList.class, is);
            System.out.println(parseVo);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

/**

* @param args

* @throws Exception

public static void main(String[] args) throws Exception {

String xmlpath = "d:/test/michael/simple_testvo.xml";

Serializer serializer = new Persister();

try {

InputStreamReader is = new InputStreamReader(new FileInputStream(

xmlpath), "utf-8");

PropertyList parseVo = serializer.read(PropertyList.class, is);

System.out.println(parseVo);

} catch (Exception e) {

e.printStackTrace();

}

运行反序列化，打印Java bean信息如下：

MyTestVo : [ userName = michael , wife = 小小小 , realName = 大大 , height = 173.3 , bornDate = Wed Sep 28 17:39:59 CST 2011 ]

[二]、自定义节点名称

1.java bean

package michael.serialization.simplexml;

import java.util.Date;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;

/**
 * @blog http://www.micmiu.com
 * @author Michael
 */
@Root(name = "MyTest")
public class MyTestVo {

    @Element
    private String userName;

    @Attribute(name = "MyWife")
    private String wife;

    @Attribute
    private String realName;

    @Element(name = "born")
    private Date bornDate;

    @Element
    private Double height;

    @Override
    public String toString() {
        return "MyTestVo : [ userName = " + userName + " , wife = " + wife
                + " , realName = " + realName + " , height = " + height
                + " , bornDate = " + bornDate + " ]";
    }
    //set get ......
}

package michael.serialization.simplexml;

import java.util.Date;

import org.simpleframework.xml.Attribute;

import org.simpleframework.xml.Element;

import org.simpleframework.xml.Root;

/**

* @blog http://www.micmiu.com

* @author Michael

@Root(name = "MyTest")

public class MyTestVo {

@Element

private String userName;

@Attribute(name = "MyWife")

private String wife;

@Attribute

private String realName;

@Element(name = "born")

private Date bornDate;

@Element

private Double height;

@Override

public String toString() {

return "MyTestVo : [ userName = " + userName + " , wife = " + wife

+ " , realName = " + realName + " , height = " + height

+ " , bornDate = " + bornDate + " ]";

}

//set get ......

}

2.序列化

序列化后生成的simple_testvo.xml文件如下：

<MyTest MyWife="小小" realName="大大">
   <userName>michael</userName>
   <born>2011-09-28 21:47:37.455 CST</born>
   <height>173.3</height>
</MyTest>

<userName>michael</userName>

</MyTest>

可以和之前的序列化XML文件对比下，看看区别在哪里。

3.反序列化

运行反序列化程序后的打印结果如下：

MyTestVo : [ userName = michael , wife = 小小 , realName = 大大 , height = 173.3 , bornDate = Wed Sep 28 21:47:37 CST 2011 ]

[三]、嵌套对象

1.java bean

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;

/**
 * @blog http://www.micmiu.com
 * @author Michael
 */
@Root
public class ConfigurationVo {
    @Element
    private ServerVo server;

    @Attribute
    private int id;

    public ServerVo getServer() {
        return server;
    }

    public int getId() {
        return id;
    }

    public void setServer(ServerVo pServer) {
        server = pServer;
    }

    public void setId(int pId) {
        id = pId;
    }

}

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;

import org.simpleframework.xml.Element;

import org.simpleframework.xml.Root;

/**

return server;

}

public int getId() {

return id;

}

public void setServer(ServerVo pServer) {

server = pServer;

}

public void setId(int pId) {

id = pId;

}

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;
/**

 */
@Root
public class ServerVo {
    @Attribute
    private int port;

    @Element
    private String host;

    @Element
    private SecurityVo security;

    public int getPort() {
        return port;
    }

    public String getHost() {
        return host;
    }

    public SecurityVo getSecurity() {
        return security;
    }

    public void setPort(int pPort) {
        port = pPort;
    }

    public void setHost(String pHost) {
        host = pHost;
    }

    public void setSecurity(SecurityVo pSecurity) {
        security = pSecurity;
    }

}

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;

import org.simpleframework.xml.Element;

import org.simpleframework.xml.Root;

/**

public int getPort() {

return port;

}

public String getHost() {

return host;

}

public SecurityVo getSecurity() {

return security;

}

public void setPort(int pPort) {

port = pPort;

}

public void setHost(String pHost) {

host = pHost;

}

public void setSecurity(SecurityVo pSecurity) {

security = pSecurity;

}

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;

/**
 * @blog http://www.micmiu.com

 */
@Root
public class SecurityVo {
    @Attribute
    private boolean ssl;

    @Element
    private String keyStore;

    public boolean isSsl() {
        return ssl;
    }

    public String getKeyStore() {
        return keyStore;
    }

    public void setSsl(boolean pSsl) {
        ssl = pSsl;
    }

    public void setKeyStore(String pKeyStore) {
        keyStore = pKeyStore;
    }

}

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;

import org.simpleframework.xml.Element;

import org.simpleframework.xml.Root;

/**

* @blog http://www.micmiu.com

* @author Michael

@Root

public class SecurityVo {

@Attribute

private boolean ssl;

@Element

private String keyStore;

public boolean isSsl() {

return ssl;

}

public String getKeyStore() {

return keyStore;

}

public void setSsl(boolean pSsl) {

ssl = pSsl;

}

public void setKeyStore(String pKeyStore) {

keyStore = pKeyStore;

}

2.序列化

/**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        String xmlpath = "d:/test/michael/simple_testvo.xml";

        SecurityVo security = new SecurityVo();
        security.setSsl(true);
        security.setKeyStore("Michael");

        ServerVo server = new ServerVo();
        server.setHost("www.micmiu.com");
        server.setPort(8088);
        server.setSecurity(security);

        ConfigurationVo config = new ConfigurationVo();
        config.setId(10000);
        config.setServer(server);

        Serializer serializer = new Persister();
        try {
            File xmlFile = new File(xmlpath);
            serializer.write(config, xmlFile);
        } catch (Exception e) {
            e.printStackTrace();
        }
}

/**

* @param args

* @throws Exception

public static void main(String[] args) throws Exception {

String xmlpath = "d:/test/michael/simple_testvo.xml";

SecurityVo security = new SecurityVo();

security.setSsl(true);

security.setKeyStore("Michael");

ServerVo server = new ServerVo();

server.setHost("www.micmiu.com");

server.setPort(8088);

server.setSecurity(security);

ConfigurationVo config = new ConfigurationVo();

config.setId(10000);

config.setServer(server);

Serializer serializer = new Persister();

try {

File xmlFile = new File(xmlpath);

serializer.write(config, xmlFile);

} catch (Exception e) {

e.printStackTrace();

}

运行上述方法，序列化生成的XML文件如下：

<configurationVo id="10000">
   <server port="8088">
      <host>www.micmiu.com</host>
      <security ssl="true">
         <keyStore>Michael</keyStore>
      </security>
   </server>
</configurationVo>

<host>www.micmiu.com</host>

<keyStore>Michael</keyStore>

</security>

</server>

</configurationVo>

3.反序列化的方法和之前的一致，自己可以测试下结果是否正确。

[四]、可选的非强制性的元素或属性

1.java bean

package michael.serialization.simplexml;

import java.util.Date;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;

/**
 * @blog http://www.micmiu.com
 * @author Michael
 */
@Root
public class MyTestVo {

    @Element
    private String userName;

    // 不是每个人都有妻子的 吼吼
    @Attribute(required = false)
    private String wife;

    @Attribute
    private String realName;

    // 不想泄露年龄噢
    @Element(required = false)
    private Date bornDate;

    @Element
    private Double height;

    @Override
    public String toString() {
        return "MyTestVo : [ userName = " + userName + " , wife = " + wife
                + " , realName = " + realName + " , height = " + height
                + " , bornDate = " + bornDate + " ]";
    }

   //省略setter getter方法

}

package michael.serialization.simplexml;

import java.util.Date;

import org.simpleframework.xml.Attribute;

import org.simpleframework.xml.Element;

import org.simpleframework.xml.Root;

/**

* @blog http://www.micmiu.com

* @author Michael

@Root

public class MyTestVo {

@Element

private String userName;

// 不是每个人都有妻子的吼吼

@Attribute(required = false)

private String wife;

@Attribute

private String realName;

// 不想泄露年龄噢

@Element(required = false)

private Date bornDate;

@Element

private Double height;

@Override

public String toString() {

return "MyTestVo : [ userName = " + userName + " , wife = " + wife

+ " , realName = " + realName + " , height = " + height

+ " , bornDate = " + bornDate + " ]";

}

//省略setter getter方法

}

2.序列化

 /**
     * @param args
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {
        String xmlpath = "d:/test/michael/simple_testvo.xml";

        MyTestVo vo = new MyTestVo();
        vo.setUserName("michael");
        vo.setRealName("大大");
        vo.setHeight(173.3d);

        Serializer serializer = new Persister();
        try {
            File xmlFile = new File(xmlpath);
            serializer.write(vo, xmlFile);
        } catch (Exception e) {
            e.printStackTrace();
        }
}

/**

* @param args

* @throws Exception

public static void main(String[] args) throws Exception {

String xmlpath = "d:/test/michael/simple_testvo.xml";

MyTestVo vo = new MyTestVo();

vo.setUserName("michael");

vo.setRealName("大大");

vo.setHeight(173.3d);

Serializer serializer = new Persister();

try {

File xmlFile = new File(xmlpath);

serializer.write(vo, xmlFile);

} catch (Exception e) {

e.printStackTrace();

}

运行序列化程序后生成的XML文件如下：

<myTestVo realName="大大">
   <userName>michael</userName>
   <height>173.3</height>
</myTestVo>

<userName>michael</userName>

</myTestVo>

3.反序列化

运行反序列化程序后打印结果如下：

MyTestVo : [ userName = michael , wife = null , realName = 大大 , height = 173.3 , bornDate = null ]

[五]、List<Object>处理

1.java bean

subvo.setName("B");

subvo.setValue("侧福晋");

subList.add(subvo);

subvo = new EntryVo();

subvo.setName("C");

subvo.setValue("小三");

subList.add(subvo);

subvo = new EntryVo();

subvo.setName("D");

subvo.setValue("二奶");

subList.add(subvo);

vo.setList(subList);

return vo;

}

运行序列化程序后生成的XML文件如下：

<propertyList name="Wife List">
   <list class="java.util.ArrayList">
      <entryVo name="A">
         <value>福晋</value>
      </entryVo>
      <entryVo name="B">
         <value>侧福晋</value>
      </entryVo>
      <entryVo name="C">
         <value>小三</value>
      </entryVo>
      <entryVo name="D">
         <value>二奶</value>
      </entryVo>
   </list>
</propertyList>

</entryVo>

</entryVo>

</entryVo>

</entryVo>

</list>

</propertyList>

3.反序列化，运行结果打印对象信息如下：

PropertyList : [ name = Wife List , EntryVo list size = 4 ] .

4.修改注解@ElementList的参数

    @ElementList(name = "WifeList", entry = "wife")
    private List<EntryVo> list;

1 2	@ElementList(name = "WifeList", entry = "wife") private List<EntryVo> list;

序列化后生成的XML文件如下：

<propertyList name="Wife List">
   <WifeList class="java.util.ArrayList">
      <wife name="A">
         <value>福晋</value>
      </wife>
      <wife name="B">
         <value>侧福晋</value>
      </wife>
      <wife name="C">
         <value>小三</value>
      </wife>
      <wife name="D">
         <value>二奶</value>
      </wife>
   </WifeList>
</propertyList>

</wife>

</wife>

</wife>

</wife>

</WifeList>

</propertyList>

注意XML文件的变化。

[六]、 inline 参数用法

1.java bean

以上节中得bean为基础修改注解如下：

@Root
public class PropertyList {

    @ElementList(name = "WifeList", entry = "wife", inline = true)
    private List<EntryVo> list;

    @Attribute
    private String name;

    public List<EntryVo> getList() {
        return list;
    }

    public String getName() {
        return name;
    }

    public void setList(List<EntryVo> pList) {
        list = pList;
    }

    public void setName(String pName) {
        name = pName;
    }

    @Override
    public String toString() {
        return "PropertyList : [ name = " + name + " , EntryVo list size = "
                + list.size() + " ] .";
    }
}

@Root

public class PropertyList {

@ElementList(name = "WifeList", entry = "wife", inline = true)

private List<EntryVo> list;

@Attribute

private String name;

public List<EntryVo> getList() {

return list;

}

public String getName() {

return name;

}

public void setList(List<EntryVo> pList) {

list = pList;

}

public void setName(String pName) {

name = pName;

}

@Override

public String toString() {

return "PropertyList : [ name = " + name + " , EntryVo list size = "

+ list.size() + " ] .";

}

2.序列化后生成的XML文件如下：

<propertyList name="Wife List">
   <wife name="A">
      <value>福晋</value>
   </wife>
   <wife name="B">
      <value>侧福晋</value>
   </wife>
   <wife name="C">
      <value>小三</value>
   </wife>
   <wife name="D">
      <value>二奶</value>
   </wife>
</propertyList>

</wife>

</wife>

</wife>

</wife>

</propertyList>

和上节生成的文件相比，XML结构少了一个层次。

[七]、构造函数的注解处理

1.java bean

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;
import org.simpleframework.xml.Serializer;
import org.simpleframework.xml.core.Persister;

/**
 * @blog http://www.micmiu.com
 * @author Michael
 */
@Root
public class EntryVo {
    public EntryVo(@Attribute(name = "name")
    String name, @Element(name = "value")
    String value) {
        this.name = name;
        this.value = value;
    }

    @Attribute(name = "name")
    private String name;

    @Element(name = "value")
    private String value;

    public String getName() {
        return name;
    }

    public String getValue() {
        return value;
    }

    public void setName(String pName) {
        name = pName;
    }

    public void setValue(String pValue) {
        value = pValue;
    }

    @Override
    public String toString() {
        return "EntryVo : [ name = " + name + ", value = " + value + " ].";
    }
}

package michael.serialization.simplexml;

import org.simpleframework.xml.Attribute;

import org.simpleframework.xml.Element;

import org.simpleframework.xml.Root;

import org.simpleframework.xml.Serializer;

import org.simpleframework.xml.core.Persister;

/**

* @blog http://www.micmiu.com

* @author Michael

@Root

public class EntryVo {

public EntryVo(@Attribute(name = "name")

String name, @Element(name = "value")

String value) {

this.name = name;

this.value = value;

}

@Attribute(name = "name")

private String name;

@Element(name = "value")

private String value;

public String getName() {

return name;

}

public String getValue() {

return value;

}

public void setName(String pName) {

name = pName;

}

public void setValue(String pValue) {

value = pValue;

}

@Override

public String toString() {

return "EntryVo : [ name = " + name + ", value = " + value + " ].";

}

2.序列化

生成的XML文件如下：

<entryVo name="blog">
<value>http://www.micmiu.com</value>
</entryVo>

<value>http://www.micmiu.com</value>

</entryVo>

3.反序列化

反序列化生成的bean的信息打印如下：

EntryVo : [ name = blog, value = http://www.micmiu.com ].

ps：如果java bean有参数的构函数，需要在构造函数的参数前也加上相应的注解，否则在反序列化时会出错。

本文就先介绍到这，下次再介绍其他运用事例。
