1.导入jar包：
org.aspectj
aspectjweaver
1.8.9
2.编写切面类： //切面类：功能的关注点
public class UsefulAspect {
public void sayHello(JoinPoint jp) {
System.out.println("hello");
}
public void sayBye() {
System.out.println("bye");
}
}
3.在XML中进行配置：
1 xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"
3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
4 xmlns:aop="http://www.springframework.org/schema/aop"
5 xsi:schemaLocation="http://www.springframework.org/schema/beans
6 http://www.springframework.org/schema/beans/spring-beans.xsd
7 http://www.springframework.org/schema/context
