我收到以下錯誤：

persistence.xml位於構建路徑中的src/META-INF中，因此應該正確找到它。有人有主意嗎？

Answer 1

嗯，我通常將persistence.xml放置在資源文件夾/src/main/resouces/META-INF/persistence.xml中，因爲我確實記得構建中沒有將資源複製到輸出目錄的問題。

我只是看看我們的配置，它看起來有點不同：

<!-- 
    - Drives transactions using local JPA APIs 
--> 
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory"/> 
</bean> 

<tx:annotation-driven mode="aspectj" proxy-target-class="true" /> 

<!-- 
    Custom PersistenceUnitManager, that reads all persistence.xml files in the 
    classpath and merges them to one single virtual persistence.xml. 

    In order to operate properly, all persistence.xml have to define the same 
    persistence unit name. 
--> 
<bean id="persistenceUnitManager" class="de.cware.cweb.jpa.MergingPersistenceUnitManager"> 
    <property name="persistenceXmlLocations"> 
     <list> 
      <value>classpath*:META-INF/persistence.xml</value> 
     </list> 
    </property> 
    <property name="defaultDataSource" ref="dataSource"/> 
</bean> 

<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate"> 
    <property name="entityManagerFactory" ref="entityManagerFactory"/> 
</bean> 

<!--

    <property name="defaultTransactionIsolation" value="#{ T(java.sql.Connection).TRANSACTION_READ_COMMITTED}"/> 
</bean> 

希望這有助於:-)

Answer 2

• 保持你的persistence.xml中WEB-INF/classes/META-INF/persistence.xml

• remove hibernate confl icting庫....

• 刪除休眠 - 3.2.0 JAR如果休眠核心是有

Answer 3

是映射類的關係與其他非映射類休眠可能發生這種錯誤，一個解決方案是將關係項檢查爲@transient（hibernate將忽略它，只用它來檢查這是否是錯誤，並稍後映射相關類）。例如：

@Entity 
public class City { 

@Id 
@GeneratedValue(strategy=GenerationType.AUTO) 
private int id; 

private String name; 

@Transient 
private State state; 

public int getId() { 
    return id; 
} 

public void setId(int id) { 
    this.id = id; 
} 

public String getName() { 
    return name; 
} 

public void setName(String name) { 
    this.name = name; 
} 

public State getState() { 
    return state; 
} 

public void setState(State state) { 
    this.state = state; 
} 

} 

而這正是非映射類，它可能會給錯誤：

public class State { 

private String name; 

}

發生在一個資源文件夾/src/main/resouces/META-INF/persistence.xml persistence.xml中對於我來說，這個工作解決方案
