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
     
       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
     
       list = new UserActiveResult
      
       ();		list.setCode("200");		list.setMessage("success");				User user = new User();		user.setId(1);		user.setName("张三");				list.setData(user);					return list;			}}
