Srpingboot中API中的注解

Springboot中@RequestParam注释post请求的参数时，默认该参数的Required=true，且该API只支持提交form形式的数据，想以Json形式提交post请求的话，可以用@RequestBody注释

以下是@PathVariable, @RequestParam和@RequestBody的区别

	支持的类型	支持的Content-Type	请求举例
@PathVariable	GET	所有	/test/{id}
@RequestParam	GET	所有	/test?id=1
	POST/PUT/DELETE/PATCH	form-data或x-www.form-urlencoded	id:1
@RequestBody	POST/PUT/DELETE/PATCH	Json	{"id":1}

@RequestBody的使用举例：

@ApiOperation(value="check user by email",notes = "通过邮箱验证用户是否存在")
@RequestMapping(value = "/checkLogin", method = RequestMethod.POST)
public Response<String>  checkLogin(
        @ApiParam(value = "user info") @RequestBody User user ){
    String email =   user.getEmail();
    String password = user.getPassword();
    Response<String> result = null ;
    String token = email+password+"qwertyuiosdfghjkzxcvbn";
    result = Response.success(token);
    return result;
}

此时访问该API的Json格式如下：

{
"email": "123",
"password": "333",
}

 

@ApiImplicitParam 默认required属性事false

@RequestParam 默认的required属性事true
