Java的Hibernate的春天AnnotationException未映射類

MVN乾淨的安裝工程沒有任何錯誤，但是當我開始的tomcat6我得到以下錯誤：Java的Hibernate的春天AnnotationException未映射類

org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.xxx.server.entity.app.App.distributions[com.xxx.server.entity.distribution.Distribution]

整個樹底：所致。

我在這裏和網上搜索了整整一天，但沒有找到適合我的工作解決方案。

設置：我想做很多與Hibernate的兩個類之間的關聯很多：App和分佈：

Distribution.java：

@Entity 
@Table(name = "DISTRIBUTION") 
public class Distribution extends xxxEntity { 

    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) 
    @JoinTable(name = "APP_DISTRIBUTION", joinColumns = { @JoinColumn(name = "distribution_id") }, inverseJoinColumns = { @JoinColumn(name = "app_id") }) 
    private Set<App> apps; 

    }

App.java：

@Entity 
@Table(name="APP") 
public class App extends xxxEntity { 

    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) 
    @JoinTable(name = "APP_DISTRIBUTION", joinColumns = { @JoinColumn(name = "app_id") }, inverseJoinColumns = { @JoinColumn(name = "distribution_id") }) 
    private Set<Distribution> distributions;

我也試了一下targetEntity。

的映射是在服務器persistence.xml文件：

另一個奇怪的事情：在項目中已經是一個工作多對多realation工作正常：

public class Info extends xxxEntity { 
    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) 
    @JoinTable(name = "USER_INFO", joinColumns = { @JoinColumn(name = "info_id") }, inverseJoinColumns = { @JoinColumn(name = "user_id") }) 
    private Set<User> users; 

public class User extends xxxEntity { 
    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) 
    @JoinTable(name = "USER_INFO", joinColumns = { @JoinColumn(name = "user_id") }, inverseJoinColumns = { @JoinColumn(name = "info_id") }) 
    private Set<Info> infos;

我寫了兩個測試，他們跑過來！

public class DistributionTest extends BaseDaoTest { 
    @Test 
    @Transactional 
    @Rollback(true) 
    public void testDistribution() { 
     // Test saving and loading Distribution 
     Distribution distribution = DomainCreator.createDistribution("Fedora", "16.01"); 
     this.distributionDao.save(distribution); 
     assertEquals(distribution, this.distributionDao.findByName("Fedora")); 

     // test loading set of distributions 
     App app = appDao.findById("a1"); 
     Set<Distribution> distros = app.getDistributions(); 
     assertEquals(3, distros.size()); 
    } 
} 

public class AppDaoTest extends BaseDaoTest { 
@Test 
@Transactional 
@Rollback(true) 
public void getAppsByDistribution() { 
    Distribution distribution = distributionDao.findById("d1"); 
    Set<App> apps = distribution.getApps(); 
    assertEquals(4, apps.size()); 
} 
}

所以我想這一定是Tomcat6的問題？

我還做了什麼：刪除Tomcat部署目錄中的所有內容，但仍然出現相同的錯誤。

有沒有人有想法？

你有沒有重命名/移動你的班？（特別是應用程序和分發）？ – 2012-03-02 15:50:02

我添加了類Distribution。應用程序保持不變。 – Flo 2012-03-05 05:53:07

之後我寫了測試通過。我有這個想法，我的本地tomcat6做錯了什麼。因此，我將更改部署到了另一臺服務器，並且在那裏工作！對不起，打擾你錯誤的問題。

非常感謝你的幫助。

乾杯，

檢查示例3在http://docs.oracle.com/javaee/5/api/javax/persistence/ManyToMany.html。所以應用程序映射應該像

@Entity 
@Table(name="APP") 
public class App extends xxxEntity { 

    @ManyToMany(mappedBy="apps") 
    private Set<Distribution> distributions;

另請檢查是否根據示例配置了joinColumns和inverseJoinColumns。

非常感謝您的回答。我嘗試過，但我得到了完全相同的錯誤。 joinColumns和inverseColumns來自 import javax.persistence.JoinColumn; import javax.persistence.ManyToMany; – Flo 2012-03-05 06:13:33
