Spring Data Interceptor EventListener

一下代码纯属个人项目应用不喜勿喷。

所有拦截器以及触发器

Interceptor 加入到程序应用当中(配置)

第一步继承拦截器

import org.hibernate.EmptyInterceptor; import org.hibernate.type.Type; import org.springframework.context.annotation.Configuration;

import java.io.Serializable;

/** * Created by pw on 2016/12/16. */ @Configuration public class AuditLogInterceptor extends EmptyInterceptor {

1@Override
2public boolean onLoad(Object entity, Serializable id, Object\[\] state, String\[\] propertyNames, Type\[\] types) {
3    return false;
4}
5
6public boolean onFlushDirty(Object entity, Serializable id, Object\[\] currentState, Object\[\] previousState, String\[\] propertyNames, Type\[\] types) {
7    return false;
8}

}

第二部 配置拦截器

spring: jpa: properties: hibernate: ejb: interceptor: com.**.AuditLogInterceptor

触发器应用配置

第一步创建触发器

import org.hibernate.HibernateException; import org.hibernate.event.spi.LoadEvent; import org.hibernate.event.spi.LoadEventListener; import org.springframework.stereotype.Component;

import java.util.EventListener;

/** * Created by pw on 2016/12/16. */ @Component public class MyLoadEventListener implements LoadEventListener{

1public void onLoad(LoadEvent event, LoadType loadType) throws HibernateException{
2    System.out.println("MyLoadEventListener -->onLoad");
3}

}

第二部配置触发器

import org.hibernate.event.service.spi.EventListenerRegistry; import org.hibernate.event.spi.EventType; import org.hibernate.internal.SessionFactoryImpl; import org.hibernate.jpa.HibernateEntityManagerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct; import javax.persistence.EntityManagerFactory;

/** * Created by pw on 2016/12/19. */ @Component public class HibernateListenersConfigurer { @Autowired private EntityManagerFactory entityManagerFactory;

1@Autowired
2private  MyLoadEventListener loadEventListener;
3
4@PostConstruct
5public void registerListeners() {
6    HibernateEntityManagerFactory hibernateEntityManagerFactory = (HibernateEntityManagerFactory) this.entityManagerFactory;
7    SessionFactoryImpl sessionFactoryImpl = (SessionFactoryImpl) hibernateEntityManagerFactory.getSessionFactory();
8    EventListenerRegistry registry = sessionFactoryImpl.getServiceRegistry().getService(EventListenerRegistry.class);
9
10    System.out.println("\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*");
11    registry.getEventListenerGroup(EventType.LOAD).appendListener(loadEventListener);
12
13}

}
