与Spring和Hibernate的Bean验证不起作用

我试图验证这个bean：与Spring和Hibernate的Bean验证不起作用

public class NewUserCompanyForm implements Serializable { 
private static final long serialVersionUID = 6414340627544822204L; 

@Email(groups = ValidationGroup1.class) 
@NotBlank(groups = ValidationGroup1.class) 
@Length(min = 5) 
private String userName; 

@NotBlank(groups = ValidationGroup1.class) 
private String password; 

@NotBlank(groups = ValidationGroup1.class) 
private String repeatedPassword; 

@NotBlank(groups = ValidationGroup2.class) 
private String companyName; 

@Pattern(regexp = "\\d\\d-\\d\\d\\d", groups = ValidationGroup2.class) 
private String postalCode; 

@NotBlank(groups = ValidationGroup2.class) 
@Pattern(regexp = "\\p{L}*", groups = ValidationGroup2.class) 
private String city; 

@Pattern(regexp = "[-A-Za-z0-9 ,.]*", groups = ValidationGroup2.class) 
@NotBlank(groups = ValidationGroup2.class) 
private String addressDetails;

几乎所有现场验证不幸的是我得到的例外：

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 'javax.validation.constraints.Email' validating type 'java.lang.String'. Check configuration for 'userName'

这是总是UnexpectedTypeException: HV000030。我阅读了Hibernate和Spring验证的文档，并且一切似乎都没有问题，例如， @Email注释可以与字符串一起使用。

编辑：添加的pom.xml

这里是被用来测试验证类：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = {SpringWebFlowConfiguration.class, WebConfiguration.class}) 
public class NewUserCompanyFormValidationTest { 
    @Autowired 
    @Qualifier("localValidatorFactoryBean") 
    private LocalValidatorFactoryBean validator; 
    @Autowired 
    private MessageSource messageSource; 

    @Test 
    public void DependencyInjectionTest(){ 
     Assert.assertNotNull(validator); 
    } 

    @Test 
    public void NewUserCompanyFormValidatingTest(){ 
     NewUserCompanyForm form1=new NewUserCompanyForm(); 
     form1.setPassword(""); 
     form1.setUserName(""); 
     form1.setRepeatedPassword(""); 
     Set<ConstraintViolation<NewUserCompanyForm>> volations1=validator.validate(form1,NewUserCompanyForm.ValidationGroup1.class); 

    } 
}

如果你有一个messages.properties，并且在它内部有一个键“javax.validation.constraints.Email”，你看了你的项目（或者在spring/hibernate验证jar里面），因为这是错误所抱怨的 –

不，在message.properties文件中没有这样的密钥。手动添加它并没有帮助。 – ariiiiiii

您能否提供额外的代码和/或配置（例如最小的'pom.xml'）以便更容易地重现您的问题？我之前使用过bean验证，但在完整的Spring + Jersey Web应用程序中。如果可能，我想用比这更少的努力重现您的问题。 :) –

基于对https://stackoverflow.com/a/17086477/1840078读我猜测，这个问题是多余的，可能与冲突的bean验证注释有冲突。当出现@Email注释时，@NotBlank注释是多余的，机会是@Length注解也是多余的。有效的电子邮件地址不能为空，并且对于具有顶级域名的电子邮件主机，其全限定主机名的长度必须至少为5。

我试着只留下@Email注释。不幸的是，这并没有解决问题。 – ariiiiiii
