sping aop切面不执行~~~_course

xml配置 <aop:config > <aop:aspect id="aoptest" ref="test"> <aop:before method="loginVerify" arg-names="req1" pointcut="within(web.netctoss.controller.FeeListController) and args(req1)"/> <aop:after method="exe" pointcut="within(web.netctoss.controller.FeeListController)"/> </aop:aspect> </aop:config> ================ 类： public class test { public void exe(){ System.out.println(new Date()+"进行了操作"); } public void loginVerify(HttpServletRequest req1){ System.out.println("haha"); } } 刚学习 spring aop 今天遇到一个问题，搞了一上午也没解决。 loginVerify方法里加一个参数就不能执行，如果去掉参数在访问页面就可以运行。 请问下这是什么原因，在线等~~

spring的aop技术，进不去切面方法，求助_course

spring中AOP切面的问题。_course

package com.dao; import org.springframework.stereotype.Repository; import com.imp.AopPersonImp; @Repository public class AopPersonDao implements AopPersonImp { /* (non-Javadoc) * @see com.dao.AopPersonImp#save() */ public void save(String name){ System.out.println("增加的名称："+name); } } --------------------------------- package com.service; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.dao.AopPersonDao; @Service public class AopPersonService { @Resource private AopPersonDao aopPersonDao; public void add(String name){ aopPersonDao.save(name); } } 在AopPersonService中注入AopPersonDao。 -------------------------------------------- package com.aop; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; import org.springframework.stereotype.Component; @Aspect @Component public class MyAopInterceptor { //"execution (*

----------------------------------------------------- 问题：如果将AopPersonSercice中AopPersonDao依赖注入注销的话，在执行aopTest1中可以成功获取aop前置通知。 如果将AopPersonDao依赖注入到AopPersonSercice中，在执行aopTest2时会报错。下面是报错提示：
