使用休眠（JPA）查詢Postgresql沒有找到表

我正在開發一個使用JPA與Hibernate和Postgresql的應用程序。使用Netbeans嚮導，我從現有數據庫創建實體類。從這個類的一個提取物如下：使用休眠（JPA）查詢Postgresql沒有找到表

@Entity 
@Table(name = "ADM_TYPES") 
@XmlRootElement 
@NamedQueries({ 
    @NamedQuery(name = "AdmTypes.findAll", query = "SELECT a FROM AdmTypes a"), 
    @NamedQuery(name = "AdmTypes.findByCType", query = "SELECT a FROM AdmTypes a WHERE a.cType = :cType"), 
    @NamedQuery(name = "AdmTypes.findByVlType", query = "SELECT a FROM AdmTypes a WHERE a.vlType = :vlType"), 
    @NamedQuery(name = "AdmTypes.findByDsType", query = "SELECT a FROM AdmTypes a WHERE a.dsType = :dsType"), 
    @NamedQuery(name = "AdmTypes.findByVlStatus", query = "SELECT a FROM AdmTypes a WHERE a.vlStatus = :vlStatus"), 
    @NamedQuery(name = "AdmTypes.findByCTypePrefix", query = "SELECT a FROM AdmTypes a WHERE a.cType like :cTypePrefix")}) 
public class AdmTypes implements Serializable {

在EJB我有：

@Stateless 
@LocalBean 
public class ModelManagement { 
    @PersistenceContext 
    private EntityManager em; 

    public List<AdmTypes> listAdmTypesPrefix(String prefix){ 
     TypedQuery<AdmTypes> query = em.createNamedQuery("AdmTypes.findByCTypePrefix", AdmTypes.class); 
     query.setParameter("cTypePrefix", "'%"+prefix+"%'"); 
     return query.getResultList(); 
    }

當我嘗試執行ModelManagement.listAdmTypesPrefix("APREFIX")它生成以下錯誤：

我知道Postgres對於大寫的表名很討厭，但是如何將查詢更改爲指向「ADM_TYPES」而不是AdmTypes？不應該自動完成（畢竟我從現有數據庫創建實體類）？代碼有什麼問題？

謝謝！

如果您刪除'from'「'％」+前綴+「％'」'？（它看起來不正確）。 – esej 2012-07-21 21:07:38

不，這就是它應該完成「類似」比較的方式。 – 2012-07-21 21:52:54

Postgres（用於，不確定更新）將表名轉換爲小寫。這是首選的操作程序。如果你記錄你的查詢，你會看到hibernate可能會或可能不會引用你的表名（我猜它不是）。

Hibernate saving User model to Postgres

老實說，如果你在運行的Postgres你真的應該要麼配置Hibernate正確，或者像我想看看它，你的正常化數據庫表不應該有一個命名空間衝突（從而消除問題）。

//從文章...

@Entity 
@Table(name="\"User\"") 
public class User { 
    ... 
}

EDITED 12年7月31日：

這種變化必須採取措施以下列方式將表的字段：

對於@Column，更改列的名稱加入逃逸「：

@Column(name = "\"C_MODEL\"")

對於@JoinColumn，更改列添加'的名字：

@JoinColumn(name = "`TP_MODEL`")

你將不得不做手工上會發生錯誤的列。

我會試試這個，讓你知道！ – 2012-07-21 21:52:27

Urk，那太可怕了。 Hibernate應該默認引用表名。我個人認爲Hibernate缺陷並沒有這麼做 - 如果它本應以這種方式工作，那肯定是一個NetBeans模型生成器錯誤。 – 2012-07-22 02:59:38

你是對的@CraigRinger，這聽起來像是一個錯誤，似乎已經被報告 – 2012-07-23 21:31:47
