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;

	}
}
