LogInterceptor 类：

package com.mth.aop;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

/**

*/
// @Aspect
// @Component
public class LogInterceptor {
// 多个一样的植入点可以抽出来定义
// @Pointcut("execution(public void com.mth.impl..*.*(..))")
public void myMethod() {

}

// 在方法执行之前先要执行这个方法
// 植入点语句
// @Before("execution(public void com.mth.impl.StuDaoImpl.save*(com.mth.bean.Student))")
public void before() {
System.out.println("before save");
}

// 方法正常执行完成之后（参数就是方法名）
// @AfterReturning("myMethod()")
public void afterReturning() {
System.out.println("after save");
}

// 方法抛异常之后执行(StuDaoImpl里面的保存学生方法)
// @AfterThrowing("myMethod()")
public void afterThrowing() {
System.out.println("afterThrowing");
}

// 环绕方法
// @Around("myMethod()")
public void aroundMethod(ProceedingJoinPoint pjp) throws Throwable {
System.out.println("around save start");
pjp.proceed();
System.out.println("arround save end");
}

// 最终通知 任意返回值类型 com.mth下的任意包中的任意类中的任意方法 参数任意
// @After("execution(* com.mth..*.*(..))")
public void afterMethod() {
System.out.println("---------after----------");
}

}

StuDaoImpl：

package com.mth.impl;

import org.aspectj.lang.annotation.AfterThrowing;
import org.springframework.stereotype.Component;

import com.mth.bean.Student;
import com.mth.dao.IStuDao;

@Component("stuDao")
public class StuDaoImpl implements IStuDao {

@Override
public void saveStu(Student stu) {
System.out.println("保存学生");
//配合注解@AfterThrowing测试
// throw new RuntimeException();
}

}

Service:

package com.mth.service;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;

import com.mth.bean.Student;
import com.mth.dao.IStuDao;
@Component("ser")
public class Service {
private IStuDao dao;

public IStuDao getDao() {
return dao;
}

@Resource(name="stuDao")
public void setDao(IStuDao dao) {
this.dao = dao;
}

public void saveStu(Student student) {
dao.saveStu(student);
}

}

测试代码：

package com.mth.test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.mth.bean.Student;
import com.mth.service.Service;

public class Test {

/**
* @Title: main
* @Description: 测试Spring注解
* @param @param args 设定文件
* @return void 返回类型
* @throws
*/
public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
"applicationContext.xml");
Service service = (Service) context.getBean("ser");
service.saveStu(new Student());
}
}
