我收到以下错误：

这是我的persistence.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
        </properties>
    </persistence-unit>
</persistence>

这是我的persistenceLayer.xml：

            <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
        </property>
    </bean>

</beans>

persistence.xml位于src / META-INF中，该文件位于构建路径中，因此应正确找到它。谁有想法？

问题答案：

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输出目录的问题。

我只是看了看我们的配置，看起来有些不同：

<!--
    - 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>

希望这可以帮助：-）
