我收到以下错误：

persistence.xml位于构建路径中的src/META-INF中，因此应该正确找到它。有人有主意吗？

Answer 1

嗯，我通常将persistence.xml放置在资源文件夹/src/main/resouces/META-INF/persistence.xml中，因为我确实记得构建中没有将资源复制到输出目录的问题。

我只是看看我们的配置，它看起来有点不同：

<!-- 
    - 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> 

希望这有助于:-)

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

• remove hibernate confl icting库....

• 删除休眠 - 3.2.0 JAR如果休眠核心是有

Answer 3

是映射类的关系与其他非映射类休眠可能发生这种错误，一个解决方案是将关系项检查为@transient（hibernate将忽略它，只用它来检查这是否是错误，并稍后映射相关类）。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; 
} 

} 

而这正是非映射类，它可能会给错误：

public class State { 

private String name; 

}
