Java bean 转为xml

Java bean 转为xml可以采用XStream类来完成

pom.xml

<dependency>
   <groupId>com.thoughtworks.xstream</groupId>
   <artifactId>xstream</artifactId>
   <version>1.4.9</version>
</dependency>

public class BaseMessage {
　　@XStreamAliasC"ToUserName")
　　private String toUserName;
　　@XStreamAlias(" FromUserName")
　　private String fromUserName ;
　　@XStreamAliasC"CreateTime")
　　private String createTime ;
　　@XStreamAliasC"MsgType")
　　private String msgType;

       get.set...

}

@XStreamAlias("xml")
public class TextMessage extends BaseMessage {
　　@XStreamAliasC"Content")
　　private String content;

      get.set...

}

测试代码：

XStream stream = new XStream();
//
stream. processAnnotations(TextMessage. class);
String xml = stream. toXML(tm); //tm是TextMessage类对象
System. out. println(xml );

 输出结果：

<xml>
　　<ToUserName>from</ToUserName>
　　<FromUserName>to</FromUserName>
　　<CreateTime>1540898036</CreateTime>
　　<MsgType>text </MsgType>
　　<Content>还好</Content>
</xml>
