spring aop 详细记录日志问题

Question

spring aop 可以实现详细记录日志的功能吗？
如：记录方法执行时间、方法是否执行成功（是否有异常）、接收传参注释

Answer 1

当然可以

1. applicationContext.xml里配置 [code="java"]

[/code]
2. 写一个切面类

[code="java"]

@Aspect
public class FourmAspect {

@Pointcut("execution(* *.*(..))")
public void a(){}

@Around("a()")
public void around1(ProceedingJoinPoint point) throws Throwable {
    System.out.println("before1.......");
    long before = System.currentTimeMillis();
    point.proceed();
    long after = System.currentTimeMillis();
    Object[] args = point.getArgs();
    System.out.println("before2.......");

    System.out.println("总共时间："+(after - before)); }


@Before("a()")
public void before1(){
    System.out.println("before........");
}


@AfterThrowing("a()")
public void throws1(){
    System.out.println("有异常......");
}

}

[/code]
