我正在后端使用 Spring 3.1,Hibernate 3和Hibernate Validator 4开发一个Web应用程序.我正在使用JSR 303进行验证.
这是通过域类中的注释完成的.

public class StaffMember implements Serializable {
       @NotNull
    @Size(max = 30)
    // All letters,spaces and hyphens are allowed
    @Pattern(regexp = "^[^0-9_.]+$",message = ("Es sind nur Buchstaben,Leerzeichen     
         und Bindestrich erlaubt."))
    private String firstname;
   }

我编写了一个测试类来测试DAO类中的CRUD操作.此类对有效数据运行时没有错误.
现在我想编辑一个现有的对象.因此我更改了名字.我指定一个
名称无效,因为我想写一个负面的测试用例.

// Allows Spring to configure the test
@RunWith(SpringJUnit4ClassRunner.class)
// Define which configuration should be used
@ContextConfiguration(locations = { "classpath:portal-test.xml" })
@TransactionConfiguration(transactionManager = "transactionManager",defaultRollback=false)
// All methods are transactional
@Transactional
public class StaffMemberDAOTest {

private StaffMember staffMember,nextStaffMember;

@Autowired
private StaffMemberDAO staffMemberDao;

@Autowired
private Validator validator;

@Test(expected = ConstraintViolationException.class)
@Transactional
@Rollback(true)
public void testUpdateStaffMemberWithInvalidData() {

    System.out.println("--- update a staffMember (with invalid data) ---");

    // check if database is empty
    Assert.assertEquals(0,staffMemberDao.getAllStaffMembers().size());

    // add staffMember
    createStaffMember();

    // validate
    Set<ConstraintViolation<StaffMember>> violations = validator
        .validate(staffMember);

    // object is valid
    if(violations.size() == 0) {

        staffMemberDao.addStaffMember(staffMember);

    } else {

        System.out.println("Object is not valid.");

    }

    // get staffMember
    StaffMember staffMemberExpected = staffMemberDao.getStaffMember(staffMember.getStaffMemberID());

    // check data
    Assert.assertEquals(staffMember,staffMemberExpected);

    // edit data
    staffMemberExpected.setFirstname("George No 1");

    // validate
    Set<ConstraintViolation<StaffMember>> violationsUpdate = validator
    .validate(staffMemberExpected);

    // object is valid
    if(violationsUpdate.size() == 0) {

        staffMemberDao.editStaffMember(staffMemberExpected);

    } else {

        System.out.println("Object is not valid.");

    }

}

系统正确引发以下错误消息：javax.validation.ConstraintValidationException
在这种情况下,必须指出预期的例外情况.在JUnit 4中,这可能与@Test(预期)有关.

我这样做但是我收到以下错误消息：

我做错了什么？有谁能够帮我？

解决方法

以下代码将在您的代码中打印验证错误,您可以从中找到问题所在

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
        Validator validator = factory.getValidator();
        Set<ConstraintViolation<Notice>> constraintViolations = validator.validate(notice);
        for (ConstraintViolation cv : constraintViolations) {
            System.out.println("ValidatationConstraint: " + cv.getConstraintDescriptor().getAnnotation());
            System.out.println("ValidatationConstraint: " + cv.getConstraintDescriptor());
            System.out.println("ValidatationConstraint: " + cv.getMessageTemplate());
            System.out.println("ValidatationConstraint: " + cv.getInvalidValue());
            System.out.println("ValidatationConstraint: " + cv.getLeafBean());
            System.out.println("ValidatationConstraint: " + cv.getRootBeanClass());
            System.out.println("ValidatationConstraint: " + cv.getPropertyPath().toString());
            System.out.println("ValidatationConstraint: " + cv.getMessage());
        }
