Question

我正在尝试配置Spring，以便它会在我的项目中注入EntityManager类的所有实例，但我不断收到以下错误：

Error creating bean with name 'entityManagerFactory' defined in class path resource [spring-config.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.JoinColumn.foreignKey()Ljavax/persistence/ForeignKey;
Caused by: java.lang.NoSuchMethodError: javax.persistence.JoinColumn.foreignKey()Ljavax/persistence/ForeignKey;

以下是我的spring-config.xml

中的相关配置

<context:annotation-config />
<tx:annotation-driven transaction-manager="transactionManager"/>

<context:component-scan base-package="spring.homework"/>

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
        p:location="sql.properties"/>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
        p:driverClassName="${dataSource.driverClassName}"
        p:url="${dataSource.url}"
        p:username="${dataSource.userName}"
        p:password="${dataSource.password}"/>

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
      p:dataSource-ref="dataSource">
    <property name="persistenceProvider">
        <bean class="org.hibernate.jpa.HibernatePersistenceProvider"/>
    </property>
</bean>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"
            p:entityManagerFactory-ref="entityManagerFactory"/>

以下是persistence.xml的内容

    <persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
             version="2.1">
    <persistence-unit name="default"  transaction-type="JTA">
        <!--<jta-data-source>java:/DefaultDS</jta-data-source>-->
        <properties>
            <property name="connection.driver_class" value="com.mysql.jdbc.Driver"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
            <property name="hibernate.show_sql" value="false"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>
        </properties>
    </persistence-unit>
</persistence>

我发现的所有类似问题都已通过升级到JPA 2.1版本得到解决，但您可以看到我的是2.1。我试过清理和安装maven几次，但这没有帮助。我真的被困了，我希望有人可以帮助我。

Answer 1

我终于解决了这个问题，我的lib文件夹中有一个旧版本的javax.persistence.jar，我猜这个版本一直在阻止maven依赖加载。因此，在我手动删除它后，一切都开始起作用了。非常感谢那些一直试图帮助我的人。

javax.persistence.JoinColumn.foreignKey（）Ljavax /持久/ ForeignKey的;
