1.加入jackson的jar包. springmvc。
2.在响应的方法上加上@ResponseBody :把java对象转化为json对象。
3.方法的返回值可以是对象集合字符串。
package com.zhiyou100.wyf.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.zhiyou100.wyf.bean.Users;
@Controller
@RequestMapping("/ajax/")
public class AjaxController {
@RequestMapping(value="Ajax1",produces="text/html;charset=UTF-8")
@ResponseBody//把java对象转化json对象，需要使用jackson的jar包
public String ajax(String name) {//对象
System.out.println(name);
return "张三";
}
@RequestMapping("Ajax2")
@ResponseBody
public List<Users> ajax1(String name) {
System.out.println(name);
List<Users> users = new ArrayList<Users>();
Users user1 = new Users("张三1",11,"男",11,"111");
Users user2 = new Users("张三2",11,"男",11,"111");
Users user3 = new Users("张三3",11,"男",11,"111");
Users user4 = new Users("张三4",11,"男",11,"111");
Users user5 = new Users("张三5",11,"男",11,"111");
Users user6 = new Users("张三6",11,"男",11,"111");
users.add(user1);
users.add(user2);
users.add(user3);
users.add(user4);
users.add(user5);
users.add(user6);
return users;
}
}
jsp代码如下：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<link rel="stylesheet" href="/springMvc-03/css/index.css">
<script type="text/javascript" src="/springMvc-03/js/jquery-3.2.1.min.js"></script>
<script type="text/javascript">
$.post("ajax/Ajax1",{"name":"张三1"},function(data){
alert(data);
});
</script>
<script type="text/javascript">
$.post("ajax/Ajax2",{"name":"张三2"},function(result){
$.each(result,function(i,n){
alert(n.uname)
})
});
</script>
</head>
<body>
<img src="/springMvc-03/img/32551428_1231_20190617-131828.png">
</body>
</html>
如果ajax返回的为字符串，那么就会出现乱码。
1.编写注解@RequestMapping(value="ajax",produces = {"text/html;charset=utf-8"})
@RequestMapping(value="ajax",produces = {"text/html;charset=utf-8"})
2.修改配置文件，在驱动中加入代码如下
参考步骤（通过org.springframework.web.servlet.view.InternalResourceViewResolver的有参构造函数进行设置编码）：
