将对象列表发送到请求正文时，Spring Boot 中的验证不起作用

Question

我正在发送一个对象列表来请求正文，如下所示：

@PatchMapping("/branches")
    public MicApiResponse<Void> updateForManyBranches(
            @RequestBody List<@Valid RepresentativeForManyBranchesRequest> req) throws MicClientException {
        service.updateForManyBranches(req);
        return MicApiResponse.succeed();
    }

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class RepresentativeForManyBranchesRequest {
    @Valid
    private RepresentativeUserForManyBranchesRequest representativeUsers;
}

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class RepresentativeUserForManyBranchesRequest {
    private String id;
    @Required
    private String userId;
    @Required
    @Length(min = 1, max = 100)
    private String name;
    @Required
    @Length(min = 1, max = 100)
    private String position;}

当我仅发送一个对象到请求正文时，这些注释 @Required 和 @Length 起作用，但是当我发送对象列表时，它们不起作用。我应该怎么做才能解决这个问题？非常感谢

我觉得你应该这样写

public MicApiResponse<Void> updateForManyBranches(@RequestBody @Valid List<RepresentativeForManyBranchesRequest> req)
