spring AOP执行2次

奇怪的是，我自己搭建的springmvc框架就只执行了一次，但是在项目中，主执行了2次。

为什么spring AOP执行2次?

1、去掉@Component就可以了。【是否去掉@Component，要看spring的其它配置，换个文件夹，没有@Component反而不会执行aop了。】

2、日志的原因，请参照：[http://stackoverflow.com/questions/18731520/spring-aop-controller-executing-twice][http_stackoverflow.com_questions_18731520_spring-aop-controller-executing-twice]

部分代码如下：

/**
     * 
     * @author arthur.paincupid.lee
     * @since 2016.04.17
     */
    @Aspect
    @Component
    public class SysLogWithOutAnn {
    	private static final Logger logger = LoggerFactory
    			.getLogger(SysLogWithOutAnn.class);
    
    	private static String[] types = { "java.lang.Integer", "java.lang.Double",
    			"java.lang.Float", "java.lang.Long", "java.lang.Short",
    			"java.lang.Byte", "java.lang.Boolean", "java.lang.Char",
    			"java.lang.String", "int", "double", "long", "short", "byte",
    			"boolean", "char", "float" };
    
    	@Pointcut("execution(* com.paincupid.springmvc.*.controller.*.search*(..))")
    	public void searchControllerCall() {
    	}
    
    	@AfterReturning(value = "searchControllerCall()", argNames = "rtv", returning = "rtv")
    	public void searchControllerCallCalls(JoinPoint joinPoint, Object rtv)
    			throws Throwable {
    		System.out.println("---------------");
    		String classType = joinPoint.getTarget().getClass().getName();
    		Class<?> clazz = Class.forName(classType);

I don't annotate aspects with @Component annoation, try to remove it, maybe because of that is being processed twice by Spring.
