Answer 1

* com.springmodel.Qishi.tanXian()改成
execution(* com.springmodel.Qishi.tanXian())
我不知道你tanXian()这个方法怎么写的，如果上面的不行，就改成
execution(public * com.springmodel.Qishi.tanXian(**))

Answer 2

没注意到忘了些execution了不过改完之后出现

Answer 3

<bean name="logManager" class="com.study.spring.aop.LogManager"></bean>

<bean name="LogTestService" class="com.study.spring.aop.service.impl.LogTestServiceImpl"></bean>

<aop:config>
<aop:aspect id="logAspect" ref="logManager">
<aop:pointcut id="logAOP" expression="execution(* com.study.spring.aop.service.*.*(..))"/>
<aop:before method="printLog" pointcut-ref="logAOP"/>
<aop:after method="printLog" pointcut-ref="logAOP"/>
</aop:aspect>
</aop:config>

Answer 4

现在是在apc.getBean("qs")时出了异常 - -什么情况

Answer 5

at com.springmodel.test.TempTest.test(TempTest.java:13)这行贴出来看一下

Answer 6

package com.springmodel.test;import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import com.springmodel.Qishi;public class TempTest {
@Test
public void test(){
ApplicationContext apc=new ClassPathXmlApplicationContext("beans.xml");
Qishi q=(Qishi)apc.getBean("qs");
q.tanXian();
}
}但是我注释掉AOP的配置后，能够运行成功

Answer 7

http://mopishv0.blog.163.com/blog/static/54455932200911118572079/这是我刚搜到的一篇文章 应该能帮你解决问题先看一下有没有导cglib的包

Answer 8

java.lang.ClassCastException: $Proxy4
at com.springmodel.test.TempTest.test(TempTest.java:13)
造型异常，这说明你通过getBean获取出来的对象不是Qishi,com.springmodel.Shiren这个贴出来看看

Answer 9

我刚测试了一下吧，你的Qishi非接口吧，所以他无法为你生成代理对象，所以你需要有个接口，用接口的方式就可以了。
