spring aop使用笔记

定义一个aspect类:

@Aspect
public class MyAspect {

    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @Pointcut("execution(public * com..controller.*Controller.*(..)) &&" +
            "!execution(public * com..NotThisController.*(..))") 
    private void pointCut(){} 
    
    @Before("pointCut()")
	public void beforeInit() throws Throwable {
    	ServletWebRequest servletContainer = (ServletWebRequest)RequestContextHolder.getRequestAttributes();
    	HttpServletRequest request = servletContainer.getRequest();
    	HttpServletResponse response = servletContainer.getResponse();
		//do something
	}
    @After("pointCut()")
	public void afterInit() throws Throwable {
    	ServletWebRequest servletContainer = (ServletWebRequest)RequestContextHolder.getRequestAttributes();
    	HttpServletRequest request = servletContainer.getRequest();
    	HttpServletResponse response = servletContainer.getResponse();
    	        //do something
	}
}

配置文件:

<aop:aspectj-autoproxy />
    <bean class="com.abc.def.MyAspect" />

就是说只要是coontroller就会被拦截，然后先执行a,b?
execution(public * com..controller.*Controller.*(..))
这个是controller的路径吗？

对，这是controller的匹配路径，拦截后先执行before，然后是controller的方法，最后执行after

这个要怎么调用呢？

符合这个规则的方法都会被拦截并执行before和after的方法

@Pointcut("execution(public * com..controller.*Controller.*(..)) &&" +  
            "!execution(public * com..NotThisController.*(..))")
