Spring JPAHibernate EmptyInterceptor不注入EntitymanagerSpring Bean

Spring JPA / Hibernate EmptyInterceptor不注入Entitymanager / Spring Bean

该

AuditEmptyInterceptor

不是由Spring管理的豆，它是由Hibernate来实例化，所以你不能依赖注入它。

您可以改用静态委托：

public class StaticDelegateInterceptor extends EmptyInterceptor {    private static Interceptor interceptor;    public static void setInterceptor(Interceptor interceptor) {        StaticDelegate.interceptor = interceptor;    }    public boolean onSave(Object entity, Serializable id, Object[] state, String[] propertyNames, Type[] types) {      return StaticDelegate.interceptor.onSave(entity, id, state, propertyNames, types);    }    ...}

在页面上注册StaticDelegateInterceptor

persistence.xml

<persistence>    <persistence-unit name="xxx" transaction-type="RESOURCE_LOCAL">       <class>com.xxx</class>       ...       ...       <properties>          <property name="hibernate.ejb.interceptor"        value="com.company.demo.audit.StaticDelegateInterceptor" />       </properties>   </persistence-unit></persistence>

修改您当前的AuditEmptyInterceptor，使其在StaticDelegateInterceptor中进行注册：

@Named@Transactionalpublic class AuditEmptyInterceptor extends EmptyInterceptor {     @PostConstruct     public void init() {          StaticDelagateInterceptor.setInterceptor(this);     }     ...}

最后

entityManagerFactory

，

auditEmptyInterceptor

通过设置depends-on属性来确保您的bean依赖于您：

<bean id="entityManagerFactory"p:dataSource-ref="dataSource" p:jpaVendorAdapter-ref="jpaAdapter"depends-on="auditEmptyInterceptor" >...</bean>
