jsp
首先创建index.jsp页面
<script type="text/javascript"> $(function () { $("#username").click(function () { $.ajax({ url: "list",//请求地址 type: "POST", dataType: "json", success: function(data) {//data是默认的，接收前台返回的数据 //alert("success"); $.each(data, function(index,element) {//循环 $("#tr").append("<th>"+element.userid+"</th>"); $("#tr").append("<th>"+element.username+"</th>"); $("#tr").append("<th>"+element.password+"</th>"); }) } }); }); </script> </head> <body> <table align="left" border="1" cellpadding="10" cellspacing="0" id="form"> <tr> <th>id</th> <th>用户名</th> <th>密码</th> </tr> <tr id="tr"> </tr> </table> </body>
controller
上面index.jsp发送list请求，接下来是处理请求的controller
@Controller public class UserController { private static final String NONE = null; //注入ProductService @Autowired private UserMapper userMapper; /** * 查询所有用户 * @return */ @RequestMapping("/list") @ResponseBody//返回json格式的数据 public List<User> List(){ List<User> list = userMapper.list(); return list; } }
Mapper.xml
<mapper namespace="com.ssm.mapper.UserMapper"> <!-- 查询所有用户--> <select id="list" resultType="com.ssm.entity.User"> select * from user </select> </mapper>
User
public class User { private Integer userid; private String username; private String password; }
