Spring AOP aspectj的使用-优快云博客

本文介绍如何在Spring 2.x环境中使用AspectJ实现环绕通知的日志记录功能，通过两个具体的切面展示如何记录服务层和服务数据访问层的调用过程。

使用spring2.x的aop aspectj的首先需要添加asm-2.2.2.jar、asm-commons-2.2.2.jar和asm-util-2.2.2.jar，还有aspectjrt.jar和aspectjweaver.jar类包的路径之中。如果在tomcat中使用，还需要spring-tomcat-weaver.jar。

之后再配置文件中只要加入以下代码，就可以使用annotations，比较便捷的使用aop了。

<aop:aspectj-autoproxy/>

一个简单的log aop类


import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
@Aspect
public class AOPServiceLogger {
	public static final String ServiceEDP = "execution( * org.aaa.bbb.service.implement..*.*(..))";
	public static final String DAOEDP = "execution( * org.aaa.bbb.dao.hibernate..*.*(..))";
	private SRLogger log = SRLogger.getLogger(AOPServiceLogger.class);

	@Around(ServiceEDP)
	// spring中Around通知
	public Object logAround(ProceedingJoinPoint joinPoint) {
		log.info("Enter Service method : " + joinPoint.getSignature().getName() + " in class " +joinPoint.getTarget());
		Object[] args = joinPoint.getArgs();
		Object obj = null;
		try {
			obj = joinPoint.proceed(args);
		} catch (Throwable e) {
			log.error(e);
			e.printStackTrace();
		}
		log.info("Exit Service method : " + joinPoint.getSignature().getName() + " in class " +joinPoint.getTarget());
		return obj;
	}

	@Around(DAOEDP)
	// spring中Around通知
	public Object logAroundDAO(ProceedingJoinPoint joinPoint) {
		log.info("Enter DAO method : " + joinPoint.getSignature().getName() + " in class " +joinPoint.getTarget());
		Object[] args = joinPoint.getArgs();
		Object obj = null;
		try {
			obj = joinPoint.proceed(args);
		} catch (Throwable e) {
			log.error(e);
			e.printStackTrace();
		}
		log.info("Exit DAO method : " + joinPoint.getSignature().getName() + " in class " +joinPoint.getTarget());
		return obj;
	}
}
