hasError無法正常工作； 使用Hibernate進行Spring 3 MVC驗證

Question

hasError無法正常工作； Hibernate的Spring 3 MVC驗證！

也許我沒有做對，但是有人可以告訴我hasErrors（）是錯誤的。 我在輸入錯誤是我的表格，但是hasErrors從未嘗試過嗎？

Controaller：

@RequestMapping(value = "/save", method = RequestMethod.POST)
public String processValidatinForm(@ModelAttribute(" article") Article  article,
                BindingResult result) {

                System.out.println("In");

 if (result.hasErrors()) {
                    System.out.println("I found errors");
                       return "addArticle";
                }
                // Add the saved validationForm to the model

                articleService.addArticle( article);
                return "redirect:/articles.html";
            }

形式：@Entity @Table（name =“ article”）公共類文章{

@Id
@GeneratedValue
@Column(name = "article_id")
private Long articleId;

@NotEmpty
@Size(max = 20)
@Column(name = "article_name", nullable = false, length=20)
private String articleName;

@NotEmpty
@Column(name = "article_desc", nullable = false)
private String articleDesc;

@Column(name = "date_added")
private Date addedDate;

public Article() {      
}

public Long getArticleId() {
    return articleId;
}

public void setArticleId(Long articleId) {
    this.articleId = articleId;
}

public String getArticleName() {
    return articleName;
}

public void setArticleName(String articleName) {
    this.articleName = articleName;
}

public String getArticleDesc() {
    return articleDesc;
}

public void setArticleDesc(String articleDesc) {
    this.articleDesc = articleDesc;
}

public Date getAddedDate() {
    return addedDate;
}

public void setAddedDate(Date addedDate) {
    this.addedDate = addedDate;
}   

}

如果正確設置了JSR-303驗證（您具有hibernate-validator jar和<mvc:annoatation-driven /> ），則應僅使用@Valid @ModelAttribute(..) ..
