我試圖驗證這個bean：與Spring和Hibernate的Bean驗證不起作用
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;
幾乎所有現場驗證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'
這是總是UnexpectedTypeException: HV000030。我閱讀了Hibernate和Spring驗證的文檔，並且一切似乎都沒有問題，例如， @Email註釋可以與字符串一起使用。
編輯：添加的pom.xml

這裏是被用來測試驗證類：
@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);
}
}
如果你有一個messages.properties，並且在它內部有一個鍵「javax.validation.constraints.Email」，你看了你的項目（或者在spring/hibernate驗證jar裏面），因爲這是錯誤所抱怨的 –
不，在message.properties文件中沒有這樣的密鑰。手動添加它並沒有幫助。 – ariiiiiii
您能否提供額外的代碼和/或配置（例如最小的'pom.xml'）以便更容易地重現您的問題？我之前使用過bean驗證，但在完整的Spring + Jersey Web應用程序中。如果可能，我想用比這更少的努力重現您的問題。 :) –
