spring AOP的问题

[pingqunnayang]

最近在看spring AOP
做测试发现下面一个问题
这是dao

@Component("userDao")
public class UserDaoImpl implements UserDao {

	public void addUser(User user) {
		// TODO Auto-generated method stub
		System.out.println("this is add method!");
	}

	public void delUser() {
		// TODO Auto-generated method stub
		System.out.println("this is delete method!");
	}

}

--------------用的是annotation注入-----------------------
下面是service代码 注入userdao

  @Component("service.userService")
public class UserService {

	public UserDao userDao;
	public UserDao getUserDao() {
		return userDao;
	}
	
	@Resource
	public void setUserDao( UserDao userDao) {
		this.userDao = userDao;
	}
	
	
	public void addUser(User user){
	   
		this.userDao.addUser(user);
		
	}
	
	public void delUser(){
		this.userDao.delUser();
	}
}

-----------------------
这是我的Test类

   public class Test {
	
	public static void main(String[] args){
		ApplicationContext app=new ClassPathXmlApplicationContext("applicationContext.xml");
		UserService us=(UserService) app.getBean("service.userService");
		us.addUser(new User());
		us.delUser();
	}

}

----------切面----------

@Aspect
@Component
public class LogAop {
	
	@Before("execution( public void com.xiao.springsimulate.dao.UserDao.addUser(com.xiao.springsimulate.model.User))")
	public void before(){
		System.out.println(" i am befor the add method");
	}

}

运行应该会打出
i am befor the add method
his is add method!
this is delete method!

可以不会打印第一句 只打印后面两句

不知道什么原因
这是我的xml文件

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<context:annotation-config></context:annotation-config>
   <!-- @commpont @resource配置-->
    <context:component-scan base-package="com.xiao.springsimulate"></context:component-scan>
</beans>

以及后台输出的信息

2010-7-12 10:52:03 org.springframework.context.support.AbstractApplicationContext prepareRefresh
信息: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@ecd7e: display name [org.springframework.context.support.ClassPathXmlApplicationContext@ecd7e]; startup date [Mon Jul 12 10:52:03 CST 2010]; root of context hierarchy

this is add method!
this is delete method!

帮忙看下 谢谢

[猿敲月下码]

你先用传统的注入方式看看 不要用注解注入

[猿敲月下码]

表达式换下看看:
@Before("execution( public void com.xiao.springsimulate.dao.UserDao.addUser(com.xiao.springsimulate.model.User))")
改为:
@Before("execution( public void *..dao.UserDao.addUser(..))")

路过~！

[ontrackfor19888]

我看了一会儿 没发现什么问题 ！

[weir_威尔]

没看懂

[Benjamin0705]

XML 里的
<!-- autowrired配置 -->
<context:annotation-config></context:annotation-config>

需要配置下吧？

[ll3647530]

没看懂。。。

[zouzhixionghuangyue]

注解如果不行的话，可以配置XML来配置试下，另外可以用("execution( public void *..dao.UserDao.addUser(..))")这种表达式来使用一下。。
