我从数据库视图创建了实体。我的实体:
@Entity
@Table(name = "viewrpdh")
@XmlRootElement
@NamedQueries({bla bla})
public class Viewrpdh implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@NotNull
@Column(name = "tanggal")
private Date tanggal;
@Basic(optional = false)
@NotNull
@Column(name = "rPDM_bulan")
private int rPDMbulan;
@Basic(optional = false)
@NotNull
@Column(name = "rPDM_minggu_ke")
private int rPDMmingguke;
@Id
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 45)
@Column(name = "rPDM_satker_kode_departemen")
private String rPDMsatkerkodedepartemen;
@Id
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 45)
@Column(name = "rPDM_satker_kode_unit_organisasi")
private String rPDMsatkerkodeunitorganisasi;
@Id
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 45)
@Column(name = "rPDM_satker_kode_satker")
private String rPDMsatkerkodesatker;
etc;
我的servlet中的代码:
List<Viewrpdh> daftarHarian = viewrpdhFacade.aMethodUsingNamedQuery(some parameter);
request.setAttribute("daftarHarian", daftarHarian);
我的JSP中的代码:
<c:forEach var="column" items="${daftarHarian}">
<tr>
<td><c:out value="${column.rPDMsatkerkodeunitorganisasi}"/></td>
<td><c:out value="${column.rPDMsatkerkodesatker}"/></td>
<td><c:out value="${column.nilaiKotor51}"/></td>
etc
</tr>
</c:forEach>
当我运行程序时,我遇到了错误:
org.apache.jasper.JasperException: javax.el.PropertyNotFoundException: The class 'entity.Viewrpdh' does not have the property 'rPDMsatkerkodeunitorganisasi'.
当我尝试访问名为rPDM的列时会发生这种情况,但如果我尝试访问其他列,则不会发生这种情况,例如:tanggal。仅供参考,rpdh,rpdm和satker是我的数据库中的表,这些实体是由netbean生成的。请帮助我,对不起我糟糕的英语。
