@RestController
@RequestMapping("/users")
public class UsersController {
    @PostMapping("/insert")
    public RestResult insertUserInfo(@RequestParam("userId") int id, String userName, String passWord, int age,String sex, String phone) {...}
}

insertUserInfo(HttpServletRequest request) {
        String userId = request.getParameter("userId");
        String phone = request.getParameter("phone");
		...
}

public class User {
    private int id;
    private String userName;
    private String passWord;
    private int age;
    private String sex;
    private String phone;
}

@PostMapping("/insert")
    public RestResult insertUserInfo(User user) {...}

@DeleteMapping("/delete/{id}")
public RestResult deleteUser(@PathVariable("id") int userId) {...}

@PutMapping("/update/{id}")
public RestResult updateUser(@PathVariable int id, String phone) ｛...｝

@GetMapping("/query/{id}")
    public RestResult queryUser(@PathVariable int id) {...}

@PostMapping("/insert")
    public RestResult insertUserInfo(@RequestBody User user) {...}

public class User {
    private Integer id;
    @JsonProperty("name")
    private String userName;
    @JsonProperty("pass")
    private String passWord;
