spring报找不到bean但是配置文件已经配置了
SpringAop3.xml的配置文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"

default-autowire="byName">
<bean id="eatHepler" class="com.o0kiss0o.springaop.EatHelper" />
<bean id="human" class="com.o0kiss0o.springaop.Human" />
<aop:aspectj-autoproxy/>
<aop:config proxy-target-class="true">
<aop:aspect ref="eatHelper">
<aop:before method="before" pointcut="execution(* *.eatSomething(..))"/>
<aop:after method="afterReturning" pointcut="execution(* *.eatSomething(..))"/>
</aop:aspect>
</aop:config>
</beans>
测试的方法如下
package com.o0kiss0o.springaop;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
public static void main(String[] args){
ApplicationContext container = new ClassPathXmlApplicationContext("SpringAop3.xml");
//Eatable et = (Eatable)container.getBean("humanProxy");//对应SpringAop1.xml
Eatable et = (Eatable)container.getBean("human");
et.eatSomething("apple");
}
}
EatHelper 的类如下
package com.o0kiss0o.springaop;
import java.lang.reflect.Method;
import org.springframework.aop.AfterReturningAdvice;
import org.springframework.aop.MethodBeforeAdvice;
public class EatHelper implements MethodBeforeAdvice,AfterReturningAdvice{
public EatHelper(){
}
@Override
public void afterReturning(Object arg0, Method arg1, Object[] arg2,
Object arg3) throws Throwable {
// TODO Auto-generated method stub
System.out.println("After eat something ----");
}
@Override
public void before(Method arg0, Object[] arg1, Object arg2)
throws Throwable {
// TODO Auto-generated method stub
System.out.println("Before eat something ----");
}
}
但是执行的时候报了这个错误
