一、基于@PathVariable注解
二、基于@RequestParam注解
三、基于@PathVariable+@RequestParam混合
四、基于@RequestBody注解
五、基于HttpServletRequest请求
六、不基于任何注解进行表单传参

一、基于@PathVariable注解

@RestController



public class UserController {



 



    @GetMapping("/user/{username}/{password}")



    public String getUserInfo(@PathVariable("username") String username,



                              @PathVariable("password") String password){



        return username+"\n"+password;



    }



}

使用Postman进行测试

二、基于@RequestParam注解

@RestController



public class UserController {



 



    @GetMapping("/user")



    public String getUserInfo(@RequestParam("username") String username,



                              @RequestParam("password") String password){



        return username+"\n"+password;



    }



}

使用Postman进行测试

三、基于@PathVariable+@RequestParam混合

@RestController



public class UserController {



 



    @GetMapping("/user/{id}")



    public String getUserInfo(@PathVariable("id") int id,



                              @RequestParam("username") String username,



                              @RequestParam("password") String password){



        return id+"\n"+username+"\n"+password;



    }



}

使用Postman进行测试

四、基于@RequestBody注解

@RestController



public class UserController {



 



    @PostMapping("/user")



    public String getUserInfo(@RequestBody User user){



        return user.getUsername()+"\n"+user.getPassword();



    }



}

使用Postman进行测试

五、基于HttpServletRequest请求

@RestController



public class UserController {



 



    @PostMapping("/user")



    public String getUserInfo(HttpServletRequest request){



        return request.getParameter("username")+"\n"+request.getParameter("password");



    }



}

使用Postman进行测试

或者

六、不基于任何注解进行表单传参

@RestController



public class UserController {



 



    @PostMapping("/user")



    public String getUserInfo(User user){



        return user.getUsername()+"\n"+user.getPassword();



    }



}
