我正在尝试使我的Web应用程序正常工作。但是我的jsp中的对象修复存在问题。这是对象：

@Entity
public class Reparation implements Serializable {

   @EmbeddedId  
   private ReparationMId idRM;
   private int idClient;
   private String nomc;
   private String prenomc;
   private String probleme;
   private Timestamp dateDepot;
   private float prixPrevu;
   private int idEtat;
   private String etat;
   private float prixFinal;
   private Timestamp datePrevu;
   private Timestamp dateLivraison;
   private int idPersonnel;
   private String nomp;
   private String prenomp;
   private String magasin;
   private int produitClient;

   @OneToOne
   @JoinColumn(name = "idMagasin", insertable=false, updatable=false)
    Magasin magasinPoint;

   public ReparationMId getId(){
       return this.idRM;
   }

这是ReparationMId我的jsp问题：

@Embeddable
public class ReparationMId implements Serializable{
     @Column(name="id")
   Integer idReparation;
  @Column(name="idMagasin")
   Integer idMagasin;

   //implements equals and hashCode
   public Integer getIdReparation(){
       return this.idReparation;
   }

   public Integer getIdMagasin(){
       return this.idMagasin;
   }...

在我的jsp中，我无法访问idRM来获取idReparation：

<table align="center" ="3">
        <tr><th>Client</th><th>Probleme</th><th>Date dépôt</th><th>Prix prévu</th><th>etat</th><th>Pieces utilisés</th></tr>
        <c:forEach items="${reparations}" var="reparation">
        <tr>

            <td><c:out value="${reparation.nomc}"/>
            <c:out value="${reparation.prenomc}"/></td>
            <td><c:out value="${reparation.probleme}"/></td>
            <td><c:out value="${reparation.prixPrevu}"/></td>
            <td><c:out value="${reparation.etat}"/><td>
            <c:set var="rmID" scope="page" value="${reparation.idRM}"/>
            <td></td>

        </tr>
        </c:forEach>
        </table>

您会看到c：set无法使用idClient这样的基本类型，但不能使用ReparationMId类型的idRM。如何实现呢？

错误：

  

发生意外错误（类型=内部服务器错误，   状态= 500）。处理JSP页面时发生异常   [/WEB-INF/view/reparation.jsp]在第[83]行80：81：82：83：84：85：86：    堆栈跟踪：

谢谢。

那么简单 我的类Reparation的获取者是getId（）而不是getIdRM（）。 当您不知道有什么问题时，很高兴知道这一点。 感谢Avijit Barua的帮助。
