Spring AOP实例 Junit4单元测试

一、创建maven项目springAOP

TestAspect.java 基于XML配置的切面

package com.sheng.example.springaop.aspect;import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;/*** Created by Dell on 2017/1/20.*/
public class TestAspect {public void doAfter(JoinPoint jp) {System.out.println("log Ending method: " + jp.getTarget().getClass().getName() + "." + jp.getSignature().getName());}public Object doAround(ProceedingJoinPoint pjp) throws Throwable {long time = System.currentTimeMillis();Object retVal = pjp.proceed();time = System.currentTimeMillis() - time;System.out.println("process time: " + time + " ms");return retVal;}public void doBefore(JoinPoint jp) {System.out.println("log Begining method: " + jp.getTarget().getClass().getName() + "." + jp.getSignature().getName());}public void doThrowing(JoinPoint jp, Throwable ex) {System.out.println("method " + jp.getTarget().getClass().getName() + "." + jp.getSignature().getName() + " throw exception");System.out.println(ex.getMessage());}
}

TestAnnotationAspect.java 基于注解的切面

package com.sheng.example.springaop.aspect;import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;/*** Created by Dell on 2017/1/20.*/
@Aspect
public class TestAnnotationAspect {@Pointcut("execution(* com.sheng.example.springaop.service.*.*(..))")private void pointCutMethod() {}//声明前置通知@Before("pointCutMethod()")public void doBefore() {System.out.println("前置通知");}//声明后置通知@AfterReturning(pointcut = "pointCutMethod()", returning = "result")public void doAfterReturning(String result) {System.out.println("后置通知");System.out.println("---" + result + "---");}//声明例外通知@AfterThrowing(pointcut = "pointCutMethod()", throwing = "e")public void doAfterThrowing(Exception e) {System.out.println("例外通知");System.out.println(e.getMessage());}//声明最终通知@After("pointCutMethod()")public void doAfter() {System.out.println("最终通知");}//声明环绕通知@Around("pointCutMethod()")public Object doAround(ProceedingJoinPoint pjp) throws Throwable {System.out.println("进入方法---环绕通知");Object o = pjp.proceed();System.out.println("退出方法---环绕通知");return o;}
}

AOPService.java

package com.sheng.example.springaop.service;/*** Created by Dell on 2017/1/20.*/
public interface AOPService {String aoptest();
}

AOPServiceImpl.java

package com.sheng.example.springaop.service.impl;import com.sheng.example.springaop.service.AOPService;
import org.springframework.stereotype.Service;/*** Created by Dell on 2017/1/20.*/
@Service
public class AOPServiceImpl implements AOPService {@Overridepublic String aoptest() {return "aoptest";}
}

MyController.java:

package com.sheng.example.springaop.controller;import com.sheng.example.springaop.service.AOPService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;/*** Created by Dell on 2017/1/20.*/
@RestController
public class MyController {@Autowiredprivate AOPService aopService;@RequestMapping("/springaop")public String springAop(){return aopService.aoptest();}
}

启动tomcat服务，在浏览器里输入：http://localhost:8080/springaop

可以看到控制台输出：

log Begining method: com.sheng.example.springaop.service.impl.AOPServiceImpl.aoptest
进入方法---环绕通知
前置通知
后置通知
---aoptest---
最终通知
退出方法---环绕通知
process time: 0 ms
log Ending method: com.sheng.example.springaop.service.impl.AOPServiceImpl.aoptest

MyTest.java

package com.sheng.example.test;import com.sheng.example.springaop.service.AOPService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;/*** Created by Dell on 2017/1/20.*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:ApplicationContext.xml")
public class MyTest {@Autowiredprivate AOPService aopService;@Testpublic void testAOP(){System.out.println(aopService.aoptest());}
}
