Spring和Hibernate的Bean验证不起作用

标签： java spring hibernate validation spring-mvc

我试图验证这个bean：

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;

不幸的是，我几乎所有的字段验证都获得了例外：

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

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

编辑：添加了pom.xml

以下是用于测试验证的类：

@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);

    }
}

答案 0 :(得分：0)

基于对https://stackoverflow.com/a/17086477/1840078的解读，我猜测该问题是多余的，可能是冲突的bean验证注释。当存在@Email注释时，@NotBlank注释是多余的，@Length注释也可能是多余的。有效的电子邮件地址不能为空，并且对于在其完全限定的主机名中具有顶级域的电子邮件主机，其长度必须至少为5。

答案 1 :(得分：0)

检查一下...

@Email注释没有@Constraint（第36行）

@Constraint(validatedBy = { })

在validation-api-2.0.1.Final中，因此最终结果为javax.servlet.ServletException: HV000030: No validator could be found for constraint 'javax.validation.constraints.Email'
