在applicationcontext.xml加入以下配置：
[xml]
就可以正确地以AOP的方式完成原本比较繁琐的功能了。
最近把框架升级到SS2H，顺便把Spring AOP实现由原来的Schema方式改为AspectJ方式，代码如下：
[java]
import org.apache.commons.lang.time.StopWatch;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
/**

public class RunTimeHandler {
private static Logger logger = LoggerFactory.getLogger("code.coolbaby");
@Pointcut("execution(public String *()) && !execution(public String toString())" + " && target(code.coolbaby.core.CRUDActionSupport)")
void timer() {
}
@Around("timer()")
public Object time(ProceedingJoinPoint joinPoint) throws Throwable {
String clazz = joinPoint.getTarget().getClass().getSimpleName();
String method = joinPoint.getSignature().getName();
StopWatch clock = new StopWatch();
clock.start();
Object result = joinPoint.proceed();
clock.stop();
String[] params = new String[] { clazz, method, clock.getTime() + "" };
logger.info("[{}]执行[{}]方法共消耗[{}]毫秒", params);
return result;
