spring boot报错： Required request body content is missing

1.异常

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

2.问题复现

@RequestMapping(value = "/somewhere", method = POST) public SomeResponse someHandler(@RequestBody XXXDTO xxxDTO) { ... }

@RequestBody对应http请求body,当请求body为空时，异常！org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public...

3.解决方案

@RequestMapping(value = "/somewhere", method = POST) public SomeResponse someHandler(@RequestBody(required=false) XXXDTO xxxDTO) { ... }
