一 控制器
package org.fkit.controller;
import java.util.ArrayList;
import java.util.List;
import org.fkit.domain.Book;
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+MyBatis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;
}
}
二 视图
<%@ 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">

</body>
</html>
三 领域模型
package org.fkit.domain;
import java.io.Serializable;
public class Book implements Serializable {
private static final long serialVersionUID = 1L;
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;
}
@Override
public String toString() {
return "Book [id=" + id + ", name=" + name + ", author=" + author + "]";
}
}
