Hibernate spring mvc验证程序@valid'；我不为收藏工作

我一直在使用SpringMVC和hibernate注释来验证传入的请求对象，在我需要验证传入的集合之前，这一切都很好

@RequestMapping(value = "/guests", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Set<GuestResource>> postGuestsToAttendance(
        @Valid @RequestBody Set<RequestToAddGuest> guestRequests) throws FieldValidationException,
        RequestBodyResourceBadRequestException 

这是checkForErrors代码。当我只在一个单独的对象上使用@Valid时，效果非常好

protected void checkForErrors(BindingResult results) throws FieldValidationException {
    if (results.hasErrors()) {
        FieldValidationException exception = new FieldValidationException();
        exception.setFieldErrors(results.getFieldErrors());
        throw exception;
    }
}

以下是带有验证注释的RequestToAddGuest类，仅供参考：

import org.hibernate.validator.constraints.NotEmpty;
import org.hibernate.validator.constraints.SafeHtml;

public class RequestToAddGuest {

    @NotEmpty
    @SafeHtml
    public String firstName;

    @SafeHtml
    @NotEmpty
    public String lastName; 

    @SafeHtml
    public String emailAddress;

    @SafeHtml
    public String streetLine1;

    @SafeHtml
    public String streetLine2;

    @SafeHtml
    public String streetLine3;

    @SafeHtml
    public String city;

    @SafeHtml
    public String stateCode;

    @SafeHtml
    public String zip;

    @SafeHtml
    public String countryCode;

    @SafeHtml
    public String phoneArea;

    @SafeHtml
    public String phoneNumber;

    @SafeHtml
    public String phoneExtension;

}

好吧，我发现了问题。。。我被验证代码迷住了，忽略了跟踪变量名。。。我从未将验证调用更改为在单个guestRequest上调用，而不是在名为guestRequest*s的整个列表上调用*

import org.hibernate.validator.constraints.NotEmpty;
import org.hibernate.validator.constraints.SafeHtml;

public class RequestToAddGuest {

    @NotEmpty
    @SafeHtml
    public String firstName;

    @SafeHtml
    @NotEmpty
    public String lastName; 

    @SafeHtml
    public String emailAddress;

    @SafeHtml
    public String streetLine1;

    @SafeHtml
    public String streetLine2;

    @SafeHtml
    public String streetLine3;

    @SafeHtml
    public String city;

    @SafeHtml
    public String stateCode;

    @SafeHtml
    public String zip;

    @SafeHtml
    public String countryCode;

    @SafeHtml
    public String phoneArea;

    @SafeHtml
    public String phoneNumber;

    @SafeHtml
    public String phoneExtension;

}
