SSM框架以json格式传给前端页面

配置文件和由Mybatis逆向工程生成了相关的代码见  登录实现

关键的是在Controller层的方法上加入@ResponseBody注解实现json格式

在控制台输出的json格式数据

index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'test.jsp' starting page</title>
    
     <%
        pageContext.setAttribute("APP_PATH",request.getContextPath());
     %>
    <script type="text/javascript" src="${APP_PATH}/static/js/jquery-3.2.1.min.js"></script>
    <link rel="stylesheet" type="text/css" href="${APP_PATH}/static/bootstrap-3.3.7-dist/css/bootstrap.min.css">
    <script type="text/javascript" src="${APP_PATH}/static/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>

  </head>
  
  <body>
    <button id="button">获取数据</button>

          $("#button").click(function(){
              $.ajax({
                  url:"${APP_PATH}/depts",
                  success:function(result){
                      console.log(result);
                      console.log(result.length);
                      } 
                  });
          });
      
          
  
  </script>
