Spring 4驗證器NoClassDefFoundError

Question

我使用Java 1.7.0_09，Spring 4完全無xml，Intellij Idea 13.1.6和Tomcat 1.0.151。我有問題與jsr 303驗證。我想通過POST方法驗證傳遞給spring的表單。這裏是我的代碼：

控制器：

@RequestMapping(value="/register", method=POST) 
    public String processRegistration(@Valid Spitter spitter, BindingResult bindingResult) { 
     if (bindingResult.hasErrors()) { 
      return "registerForm"; 
     } 

     repository.save(spitter); 
     return "redirect:/spitter/" + spitter.getUsername(); 
    } 

這裏是我的豆：

public class Spitter { 

    private Long id; 

    @NotNull 
    @Size(min=5, max=16) 
    private String username; 

    @NotNull 
    @Size(min=5, max=25) 
    private String password; 

    @NotNull 
    @Size(min=2, max=30) 
    private String firstName; 

    @NotNull 
    @Size(min=2, max=30) 
    private String lastName; 

    private String email; 

    public Spitter() {} 

    public Spitter(String username, String password, String firstName, String lastName, String email) { 
     this(null, username, password, firstName, lastName, email); 
    } 

    public Spitter(Long id, String username, String password, String firstName, String lastName, String email) { 
     this.id = id; 
     this.username = username; 
     this.password = password; 
     this.firstName = firstName; 
     this.lastName = lastName; 
     this.email = email; 
    } 
} 

形式：

<%@ taglib uri="http://www.springframework.org/tags/form" prefix="sf" %> 

    <sf:form method="POST" commandName="spitter"> 
     First name: <sf:input path="firstName"/><br/> 
     <sf:errors path="firstName" /><br/> 
     Last name: <sf:input path="lastName"/><br/> 
     Email: <sf:input path="email"/><br/> 
     Username: <sf:input path="username"/><br/> 
     Password: <sf:input path="password"/><br/> 
     <input type="submit" value="Register"/> 
    </sf:form>

驗證似乎不點火的。無論輸入形式如何

if (bindingResult.hasErrors()) 

總是錯誤的。

爲了調試這個，我寫了一些單元測試。這裏是：

@Test 
public void carIsValid() { 
    Spitter car = new Spitter("aaaaaa","aaaaaa","aaaaaa","aaaaaa","aaaaaa"); 

    ValidatorFactory factory = Validation.buildDefaultValidatorFactory(); 
    Validator validator = factory.getValidator(); 
    Set<ConstraintViolation<Spitter>> constraintViolations = validator.validate(car); 

    assertEquals(0, constraintViolations.size()); 
} 

這裏驗證工程就像一個魅力。因爲我嘗試驗證輸入表格一樣，所以我改變我的控制器代碼：

@RequestMapping(value="/register", method=POST) 
public String processRegistration(Spitter spitter) { 

    ValidatorFactory factory = Validation.buildDefaultValidatorFactory(); 
    Validator validator = factory.getValidator(); 

    if (validator.validate(spitter).size() > 0) { 
     return "registerForm"; 
    } 

    repository.save(spitter); 
    return "redirect:/spitter/" + spitter.getUsername(); 
} 

但現在我得到錯誤：

java.lang.NoClassDefFoundError: javax/validation/Validation 

你能告訴我，爲什麼驗證不自動，爲什麼工作當我嘗試手動驗證它時，它僅適用於單元測試並在控制器代碼中崩潰？

Answer 1

您正在混合Spring bean驗證和JSR-303驗證。

我有同樣的問題，它是由按照這個答案引用的教程解決： Using both JSR-303 and Traditional Bean Validation?
