驗證文件的問題Spring mvc 3

Question

我在Spring 3項目中遇到了一些驗證文件問題。 我有這就是豆測試一個非常基本的驗證項目：

public class User { 
    @NotEmpty(message="no blank name") 
    @Size(min=2, max=20) 
    private String name=""; 

    @NotEmpty(message="no blank email") 
    @Email 
    private String email=""; 

...... getter和setter ...... 接受來自表單頁面請求的控制器中的功能並進行必要的驗證是：

@RequestMapping(value="/displayUser",method=RequestMethod.POST) 
public String displayUser(@Valid User user, Model model,BindingResult result){  
    if(result.hasErrors()){ 
     return "form"; 
    } 
    userList.add(user); 

    model.addAttribute("user",user); 

    return "redirect:displayUser"; 
} 

但我一旦不認爲代碼是問題的原因，因爲當我啓動服務器並運行項目「，它一直在努力，因爲我測試其他春天的東西在那裏「我得到以下例外：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.validation.beanvalidation.LocalValidatorFactoryBean#0': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError

你有什麼想法可以解決問題嗎？ 我想弄清楚，但沒有， PS：我使用Tomcat 6，我剛下載了：

hibernate-validator-4.0.2.FINAL.jar 

和

validation-api-1.0.0.GA.jar 

Answer 1

在我看來像類org.springframework.validation.beanvalidation.LocalValidatorFactoryBean不能在你的類路徑上解決。您需要將JAR filespring-context.jar添加到您的類路徑中。
