Spring MVCの検証で不正な状態やサーブレットの例外がスローされる

私はSpring MVC Bean検証システムを学んでいますが、私は通常のチュートリアルとドキュメントを使いましたが、私の努力だけでEclipseを生成しました。Spring MVCの検証で不正な状態やサーブレットの例外がスローされる

ここに私のコードは（私は関連する部分を掲示しています）です：

BeanクラスのArticolo

@Entity 
@Table (name="Articolo") 
public class Articolo { 

@Column (name="Ristorante") 
@NotNull (message="error") 
private String ristorante; 
.... 
.... 
.... 

public String getRistorante() { 
    return ristorante; 
} 

public void setRistorante(String ristorante) { 
    this.ristorante = ristorante; 
}

}

コントローラ

@Controller 
public class ArticleManagerController { 

@RequestMapping (value="/ArticleManager", method= RequestMethod.GET) 
public ModelAndView createArticleManager(@RequestParam(value = "IDarticolo") int IDarticolo) { 

    ModelAndView model=new ModelAndView("ArticleManager"); 

    //get article based on ID number from URL 
    //if ID=0, creates empty model (new article) 

     try { 
      NewEditArticolo nea = new NewEditArticolo(IDarticolo); 
      model.addObject("nea", nea); 

     } 

     catch (SQLException e) { 
      System.out.println("failed to generate model for article with ID " + IDarticolo); 
      e.printStackTrace(); 
     } 

    return model; 

} 



@RequestMapping (value="/ArticleManager", method=RequestMethod.POST) 

//create Articolo object and map attributes to values from ARTICLEMANAGER.JSP 
public String editArticle (@Valid @ModelAttribute ("articolo1") Articolo articolo1, 
          @ModelAttribute (value="daoArt") DAOArticolo daoArt, 
          @RequestParam (value="submit") String submit, 
          BindingResult result) { 

    //if validation fails, return ArticleManager form displaying error messages 
    if (result.hasErrors()) { 
     System.out.println("VALIDATION FAILED"); 
     return "ArticleManager"; 
    } 

    //if validation is succesfull 
    else { 
     System.out.println("VALIDATION WAS SUCCESFULL"); 
      ... 
      *more code* 
      ... 
    return submit; 

}

JSPページ

<form:form action="ArticleManager" method="POST" commandName="articolo1"> 
.... 

<tr> 
       <td>Restaurant</td> 
       <td><form:input path="ristorante" size="50" 
        placeholder="Insert restaurant name" 
        value="${nea.articolo.ristorante}" /></td> 
       <td> <form:errors path="ristorante"/> </td> 
</tr>

私は春のディスパッチャサーブレットで注釈をアクティブにしました：

<mvc:annotation-driven />

そして、ここでは、私が手例外です：

org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/ArticleManager.jsp at line 39 

36:    
37:    <tr> 
38:     <td>Restaurant</td> 
39:     <td><form:input path="ristorante" size="50" 
40:      placeholder="Insert restaurant name" 
41:      value="${nea.articolo.ristorante}" /></td> 
42:     <td> <form:errors path="ristorante"/> </td>

私はステップバイステップのいくつかのチュートリアルで見たものでしたコントローラの@Validアノテーションを使用し、jspのform：formタグを使用して、Bean上の注釈を定義しますが、実際には何かが欠落している可能性があり、それが何であるか把握できません。

私を助けてください！

根本的な原因：BindingResultどちらも使用可能なBean名のプレーンなターゲット・オブジェクトのarticolo1の要求属性として

変更戻り値の型ModelAndViewへとモデルの属性articolo1を含むようにMap<String, Object> modelを追加します。

public ModelAndView editArticle (@Valid @ModelAttribute ("articolo1") Articolo articolo1, 
          @ModelAttribute (value="daoArt") DAOArticolo daoArt, 
          @RequestParam (value="submit") String submit,

     return new ModelAndView("ArticleManager");

@Alex Redsはこの問題を解決しましたか？ –

残念ながら、私のポストでコントローラクラスの一部をスキップしたことに気がつきました...今更新しました。私が間違っていることを確認するために見たいと思うかもしれません。 –

@alex 'neo'を' articolo1'に変更する必要があります... 'model.addObject（" articolo1 "、yourObject）' ...私は現在モバイルです。私は私のところに戻ったときに答えて説明しますラップトップ...あなたはこの答えを参照してくださいhttp://stackoverflow.com/a/39696208/4117061 –
