Spring Data Interceptor EventListener

一下代码纯属我的项目应用不喜勿喷。

全部拦截器以及触发器

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 {


    @Override
    public boolean onLoad(Object entity, Serializable id, Object[] state, String[] propertyNames, Type[] types) {
        return false;
    }

    public boolean onFlushDirty(Object entity, Serializable id, Object[] currentState, Object[] previousState, String[] propertyNames, Type[] types) {
        return false;
    }


}

第二部 配置拦截器

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

 

触发器应用配置

第一步建立触发器

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{

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

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;

    @Autowired
    private  MyLoadEventListener loadEventListener;

    @PostConstruct
    public void registerListeners() {
        HibernateEntityManagerFactory hibernateEntityManagerFactory = (HibernateEntityManagerFactory) this.entityManagerFactory;
        SessionFactoryImpl sessionFactoryImpl = (SessionFactoryImpl) hibernateEntityManagerFactory.getSessionFactory();
        EventListenerRegistry registry = sessionFactoryImpl.getServiceRegistry().getService(EventListenerRegistry.class);

        System.out.println("*******************************************************");
        registry.getEventListenerGroup(EventType.LOAD).appendListener(loadEventListener);

    }
}
