javax.persistence.JoinColumn.foreignKey()Ljavax/persistence/ForeignKey；
提问于 2015-07-27 01:53:01
我正在尝试配置Spring，以便它可以注入我项目中EntityManager类的所有实例，但我总是得到以下错误：
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;下面是我的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"/>下面是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>最后是pom.xml中的依赖项

</dependencies>我发现的所有类似问题都通过升级到JPA 2.1版本得到了解决，但正如您所看到的，我的版本是2.1。我尝试过清理和安装maven几次，但都没有帮助。我真的被困住了，我希望有人能帮我。

我终于解决了这个问题，在我的lib文件夹中有一个旧版本的javax.persistence.jar，我猜它已经阻止了maven依赖的加载。所以在我手动删除它之后，一切都开始正常工作。非常感谢所有试图帮助我的人。
