Spring @GetMapping 与 @RequestBody 不能搭配使用

项目整合登录验证功能时遇到如下错误：

org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing

错误原因：

误把@GetMapping与@RequestBody放在一起使用

@GetMapping("login")
public R loginUser(@RequestBody UcenterMember member){
}

解决方式：

@GetMapping换成@PostMapping

@PostMapping("login")
public R loginUser(@RequestBody UcenterMember member){
}
