spring mvc 参数绑定，api同时有路径参数与查询参数，怎么封装到同一上bean对象上

Question

如下代码，有路径参数与查询参数，我想同时封装到SubjectRequestParams 对象上，有没有办法 @GetMapping(path = "/{subjectCode}") public ResponseEntity<?> findSubject(SubjectRequestParams requestParams){ }

Answer 1

@GetMapping(path = "/{subjectCode}")
public ResponseEntity<?> findSubject(@ModelAttribute("subjectCode") SubjectRequestParams requestParams){
}

这个注解就行了,如果多个参数

@GetMapping(path = "/{subjectCode}/{message}")
public ResponseEntity<?> findSubject(@ModelAttribute SubjectRequestParams requestParams){
}
