spring mvc: xml练习

xml练习，得到的结果是：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xml>
<code>200</code>
<message>success</message>
<user>
    <name>李四</name>
    <id>2</id>
</user>
</xml>

　　

需要用的的注解:@​​ResponseBody​​

org.springframework.web.bind.annotation.ResponseBody;

将内容输出为xml,json格式（非html格式）

其他注解：

javax.xml.bind.annotation.XmlElement;

javax.xml.bind.annotation.XmlElements;

javax.xml.bind.annotation.XmlRootElement;

javax.xml.bind.annotation.XmlAccessorType;

javax.xml.bind.annotation.XmlAccessType;

 

包名:json

 

user.java

package json;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAccessType;

@XmlRootElement
@XmlAccessorType(XmlAccessType.NONE)
public class User {

  @XmlElement
  String name;
  @XmlElement
  Integer id; 

  public User(String name, Integer id) {    
    this.name = name;
    this.id = id;
  }


  public User() { 
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public Integer getId() {
    return id;
  }

  public void setId(Integer id) {
    this.id = id;
  } 

}

　　

BaseXmlResult.java根信息

package json;

public class BaseXmlResult {

  protected String code;
  protected String message;


  public String getCode() {
    return code;
  }
  public void setCode(String code) {
    this.code = code;
  }
  public String getMessage() {
    return message;
  }
  public void setMessage(String message) {
    this.message = message;
  }   

}

　　

UserActiveResult.java User列表信息

package json;


import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElements;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAccessType;


@XmlRootElement(name="xml")
@XmlAccessorType(XmlAccessType.NONE)
public class UserActiveResult<T> extends BaseXmlResult {  

  @XmlElements({
    @XmlElement(name="user", type=User.class)
  })    
  private T data;

  public T getData() {
    return data;
  }
  public void setData(T data) {
    this.data = data;
  }

  public String getCode() {
    return code;
  }
  public void setCode(String code) {
    this.code = code;
  }
  public String getMessage() {
    return message;
  }
  public void setMessage(String message) {
    this.message = message;
  }

}

　　

再来看看UserController.java

package json;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping(value="/user")
public class UserController {

  @RequestMapping(value="/list", method=RequestMethod.GET)  
  @ResponseBody 
  public UserActiveResult getUser()
  {
    UserActiveResult<User> list = new UserActiveResult<User>();
    list.setCode("200");
    list.setMessage("success");

    User user = new User();
    user.setId(1);
    user.setName("张三");

    list.setData(user); 

    return list;

  }
}
