1.前端页面

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>测试返回JSON格式的数据</title><script type="text/javascript" src="js/jquery-1.11.0.min.js"></script><script type="text/javascript" src="js/json2.js"></script><script type="text/javascript">$(document).ready(function(){testResponseBody();});function testResponseBody(){$.post("${pageContext.request.contextPath}/json/testRequestBody",null,function(data){ $.each(data,function(){var tr  = $("<tr align='center'/>");            $("<td/>").html(this.id).appendTo(tr);            $("<td/>").html(this.name).appendTo(tr);            $("<td/>").html(this.author).appendTo(tr);            $("#booktable").append(tr);        })},"json");}</script></head><body><table id="booktable" border="1"  style="border-collapse: collapse;"><tr align="center">  <th>编号</th>  <th>书名</th>  <th>作者</th></tr></table></body></html>

2.JavaBean

Book.java

package com.bean;import java.io.Serializable;public class Book implements Serializable {private Integer id;private String name;private String author;public Book() {super();// TODO Auto-generated constructor stub}public Book(Integer id, String name, String author) {super();this.id = id;this.name = name;this.author = author;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getAuthor() {return author;}public void setAuthor(String author) {this.author = author;}@Overridepublic String toString() {return "Book [id=" + id + ", name=" + name + ", author=" + author + "]";}}

3.控制类

BookController.java

package com.control;import java.util.ArrayList;import java.util.List;import com.bean.*;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;@Controller@RequestMapping("/json")public class BookController {    @RequestMapping(value="/testRequestBody")    // @ResponseBody会将集合数据转换json格式返回客户端    @ResponseBody    public Object getJson() {    List<Book> list = new ArrayList<Book>();    list.add(new Book(1,"Spring MVC企业应用实战","肖文吉"));    list.add(new Book(2,"轻量级JavaEE企业应用实战","李刚"));    return list;    }}
