Spring Rest Controller：如何有选择地关闭validation: 在我的控制器中，我有一个创建实体的方法 import javax.validation.Valid; … @RestController public class Controller { @RequestMapping(method = RequestMethod.POST) public ResponseEntity create(@Valid @RequestBody RequestDTO requestDTO) { … 同 import org.hibernate.validator.constraints.NotEmpty; … public class RequestDTO @NotEmpty // (1) private String field1; //other fields, getters and setters. 我想添加一个控制器方法 update(@Valid @RequestBody RequestDTO requestDTO) 但是在这种方法中，应该允许field1为空或为空，即行 @NotEmpty // (1) RequestDTO应该被忽略。我怎样才能做到这一点？我是否必须编写一个与RequestDTO完全相同的类，但没有注释？或者通过inheritance以某种方式可能？
