java对象和xml互转

来源：互联网发布：jsp在线考试系统源码编辑：程序博客网时间：2024/06/10 07:06

业务：调用别人的接口，将xml格式的数据传递过去，需要将java对象转为xml形式传递；或者别人调用我们的接口，接受xml格式数据，将xml格式数据转为java对象。
使用jar包： <dependency>
<groupId>com.thoughtworks.xstream</groupId>
<artifactId>xstream</artifactId>
<version>1.4.7</version>
</dependency
1、java对象转xml
1.1 先定义java对象的类
package com.qxuninfo.app.response;

import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("PsAgentAddDetail")
public class PsAgentAddDetail {

   @XStreamAlias("openId")
   private String openId;

   @XStreamAlias("identifyNo")
   private String identifyNo;

   @XStreamAlias("name")
   private String name;

   @XStreamAlias("phoneNumber")
   private String phoneNumber;

   @XStreamAlias("comCode")
   private String comCode;

   @XStreamAlias("score")
   private int score;
}/*get和set方法省略*/
1.2 再写controller
@Controller
@RequestMapping("userSubmit")
public class UserInfoSubmitController extends WechatHttpClient {
  @RequestMapping(value="/submit",method=RequestMethod.POST)
  public void submit(){
PsAgentAddDetail psAgentAddDetail = new PsAgentAddDetail();
       psAgentAddDetail.setOpenId("123");
       psAgentAddDetail.setName("123");
       psAgentAddDetail.setPhoneNumber("123");
       psAgentAddDetail.setComCode("123");
       psAgentAddDetail.setScore(123);
       psAgentAddDetail.setIdentifyNo("123");
//传递过去的xml数据格式
       XStream xstream = new XStream(new DomDriver("utf8"));
       xstream.processAnnotations(PsAgentAddDetail.class);
       String xml = xstream.toXML(psAgentAddDetail);
       System.out.println(xml);
}
}
2、xml转java对象
2.1 同样要先定义接受xml的java对象（此处省略）
2.2 接受xml后controller进行转化
@Controller
@RequestMapping("ccic")
public class ProxyRegistServer {
@SuppressWarnings("unused")
   @RequestMapping(value="/sendTemplate",method=RequestMethod.POST)
   @ResponseBody
   public void sendTemplate(){//String xmlreturn
       //参数是一个xml 字符串将参数字符串转成对象
       String xmlreturn="<PsAgentDetail><openId>2222</openId><agentCode>123</agentCode><auditTime>1998-01-02 12:23:30</auditTime></PsAgentDetail>";
       XStream xstream = new XStream(new DomDriver("utf8"));
       xstream.processAnnotations(PsAgentDetail.class);
       PsAgentDetail psAgentDetail = (PsAgentDetail)xstream.fromXML(xmlreturn);
       System.out.println(psAgentDetail.getOpenId()+psAgentDetail.getAgentCode()+psAgentDetail.getAuditTime());
}
}
总结：总的来说还是挺简单的，我这里只是写了最简单的，若是有其他方法还请补充。参考文档;http://www.blogjava.net/bolo/a ... .html
