本文介绍如何在Spring框架中使用AOP实现事务管理，包括前置通知、后置通知和切点，以及如何记录操作日志。通过配置XML文件和实现特定接口，实现了对业务方法的统一管理和日志记录。

接口类

package com.michael.aop.log;
public interface Logable {

	public void log();

}

package com.michael.aop.log;
import java.util.Date;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;


@Component
@Aspect
public class TransHelper {


	@Before("log()")
	public void beforeConfirm() {
		System.out.println("确认来车信息记录------------之前");
	}
	@AfterReturning("log()")
	public void afterConfirm() {
		System.out.println("确认来车信息记录------------之后");


	}
	@Pointcut("execution(* *.log())")
	public void log() {
		System.out.println("我在记录操作日志--------------" + new Date());
	}
}

package com.michael.aop.log;



public class TransManager implements Logable {

	public void log() {
		System.out.println("确认来车信息记录------------");
	}
}
