需要添加方法的类：
package com.xh.spring.aop;
public class CutPoint {
public void doSomething()
{
System.out.println("I am donging something:");
}
}
提供方法的类：
package com.xh.spring.aop;
public class TestAspect {
public void doBefore()
{
System.out.println("I do it before");
}
public void doAfter()
{
System.out.println("I do it After");
}
}
测试类：
package com.xh.spring.test;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.xh.spring.aop.CutPoint;
public class CutPointTest {
@Test
public void test() {
ApplicationContext app=new ClassPathXmlApplicationContext("applicationContext.xml");
CutPoint cut=(CutPoint) app.getBean("B_cut");
cut.doSomething();
}
}
xml:
