规定请求方式 RequestMapping(value="/hello" Method=RequestMethod.GET)

@RequestMapping(value="/hello" Method="Request.Method.GET")

@ResponseBody

public String  home(){

　　return "user home";

}

//建议使用以下

@ResponseBody

@GetMapping("/hello")//PostMapping

public String show(@RequestParam("username")String username,@RequestParam("password")String password){

//@RquestParam 默认必须提供值

return "user show"+username+"__---"+password;

}
