业务Bean，接口就不贴了
package cn.itcast.service.impl; import cn.itcast.service.PersonService; public class PersonServiceBean implements PersonService { public String getPersonName(Integer id) { System.out.println("我是getPersonName()方法"); return "XXX"; } public void save(String name) { System.out.println("我是save()方法"); } public void update(String name, Integer id) { System.out.println("我是update()方法"); } }
实现AOP的类
package cn.itcast.service; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; @Aspect public class MyInterceptor { @Pointcut("execution (* cn.itcast.service.impl.PersonServiceBean.*(..))") private void anyMethod() {} @Before("anyMethod()") public void doAccessCheck(String userName) { System.out.println("前置通知"); } }
测试方法
package junit.test; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import cn.itcast.service.PersonService; public class SpringAOPTest { @Test public void interceptorTest(){ ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml"); PersonService personService = (PersonService)ctx.getBean("personService"); personService.save("xxx"); } }
