“找不到持久性单元”错误

Question

我收到以下错误：

这是我的persistence.xml文件：

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

好吧，我通常将persistence.xml放在资源文件夹/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output-directory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>

<!--
    Creates a EntityManagerFactory for use with the Hibernate JPA provider and a simple
    in-memory data source populated with test data
-->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="loadTimeWeaver">
        <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>

            <property name="showSql" value="false"/>

        </bean>
    </property>
    <property name="jpaProperties">

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

希望这可以帮助 ：-）

Answer 2

• 将您的persistence.xml保存在WEB-INF / classes / META-INF / persistence.xml中

• 删除hibernate冲突的库....

• 如果hibernate核心存在，删除hibernate - 3.2.0 jar

Answer 3

将persistence.xml放在资源文件夹/src/main/resouces/META-INF/persistence.xml对我来说这是解决方案

Answer 4

如果你有一个与其他非映射类关系的hibernate映射类，可能会发生这种错误，解决方法是将关系项检查为@transient（hibernate将忽略它，使用它只检查这是否是错误，以后映射相关的类）。 例：

@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;
}

}

这是可能给出错误的非映射类：

public class State {

private String name;

}
