操作日志对于程序员或管理员而言，可以快速定位到系统中相关的操作，而对于操作日志的管理的实现不能对正常业务实现进行影响，否则即不满足单一原则，也会导致后续代码维护困难，因此我们考虑使用AOP切面技术来实现对日志管理的实现。

文章大致内容：
1、基本概念
2、基本应用
3、日志管理实战
对这几部分理解了，会对AOP的应用应该很轻松。

一、基本概念

项目	描述
Aspect（切面）	跨越多个类的关注点的模块化，切面是通知和切点的结合。通知和切点共同定义了切面的全部内容——它是什么，在何时和何处完成其功能。事务处理和日志处理可以理解为切面
Join point（连接点）	程序执行过程中的一个点，如方法的执行或异常的处理
Advice（通知）	切面在特定连接点上采取的动作
Pointcut（切点）	匹配连接点的断言。通知与切入点表达式相关联，并在切入点匹配的任何连接点上运行(例如，具有特定名称的方法的执行)。切入点表达式匹配的连接点概念是AOP的核心，Spring默认使用AspectJ切入点表达式语言
Introduction（引用）	为类型声明其他方法或字段。Spring AOP允许您向任何建议的对象引入新的接口(和相应的实现)。例如，您可以使用介绍使bean实现IsModified接口，以简化缓存
Target object（目标）	由一个或多个切面通知的对象。也称为“通知对象”。由于Spring AOP是通过使用运行时代理实现的，所以这个对象始终是代理对象
AOP proxy（代理）	AOP框架为实现切面契约(通知方法执行等)而创建的对象。在Spring框架中，AOP代理是JDK动态代理或CGLIB代理
Weaving（织入）	织入是将通知添加对目标类具体连接点上的过程，可以在编译时(例如使用AspectJ编译器)、加载时或运行时完成

Spring切面可以应用5种类型的通知：

前置通知（Before）：在目标方法被调用之前调用通知
后置通知（After）：在目标方法完成之后调用通知（无论是正常还是异常退出）
返回通知（After-returning）：在目标方法成功执行之后调用通知
异常通知（After-throwing）：在目标方法抛出异常后调用通知
环绕通知（Around）：通知包裹了被通知的方法，在被通知的方法调用之前和调用之后执行自定义的行为
其执行的顺序为：

后续的基本应用，会将 环绕通知、前置通知、后置通知、返回通知、异常通知进行实现，并演示其执行顺序。

二、基本应用

声明通知
大家可以将下面的代码复制出来，验证上面的执行顺序。

</code></span>

其中需要注意的是切入点：@Pointcut的表达式
格式：

execution(modifiers-pattern? ret-type-pattern declaring-type-pattern? name-pattern(param-pattern)throws-pattern?)
括号中各个pattern分别表示：

修饰符匹配（modifier-pattern?）
返回值匹配（ret-type-pattern）可以为*表示任何返回值,全路径的类名等
类路径匹配（declaring-type-pattern?）
方法名匹配（name-pattern）可以指定方法名或者 代表所有, set 代表以set开头的所有方法
参数匹配（(param-pattern)）可以指定具体的参数类型，多个参数间用“,”隔开，各个参数也可以用“”来表示- 匹配任意类型的参数，如(String)表示匹配一个String参数的方法；(,String) 表示匹配有两个参数的方法，第一个参数可以是任意类型，而第二个参数是String类型；可以用(…)表示零个或多个任意参数
异常类型匹配（throws-pattern?）
其中后面跟着“?”的是可选项

示例：

1）execution(* (…))
//表示匹配所有方法
2）execution(public * com. savage.service.UserService.(…))
//表示匹配com.savage.server.UserService中所有的公有方法
3）execution(* com.savage.server….(…))
//表示匹配com.savage.server包及其子包下的所有方法

三、日志管理实战

有了上面基本应用的理解，现在我们直接就贴代码：
1、依赖的jar包

<span style="color:#000000"><code class="language-xml"><span style="color:#5c6370"><!-- aop依赖 --></span>
<span style="color:#e06c75"><span style="color:#e06c75"><span style="color:#999999"><</span>dependency</span><span style="color:#999999">></span></span>
  <span style="color:#e06c75"><span style="color:#e06c75"><span style="color:#999999"><</span>groupId</span><span style="color:#999999">></span></span>org.springframework.boot<span style="color:#e06c75"><span style="color:#e06c75"><span style="color:#999999"></</span>groupId</span><span style="color:#999999">></span></span>
  <span style="color:#e06c75"><span style="color:#e06c75"><span style="color:#999999"><</span>artifactId</span><span style="color:#999999">></span></span>spring-boot-starter-aop<span style="color:#e06c75"><span style="color:#e06c75"><span style="color:#999999"></</span>artifactId</span><span style="color:#999999">></span></span>
<span style="color:#e06c75"><span style="color:#e06c75"><span style="color:#999999"></</span>dependency</span><span style="color:#999999">></span></span>
</code></span>

2、自定义注解

<span style="color:#000000"><code class="language-java"><span style="color:#999999">@Target</span><span style="color:#999999">(</span>ElementType<span style="color:#999999">.</span>METHOD<span style="color:#999999">)</span>
<span style="color:#999999">@Retention</span><span style="color:#999999">(</span>RetentionPolicy<span style="color:#999999">.</span>RUNTIME<span style="color:#999999">)</span>
<span style="color:#c678dd">public</span> @<span style="color:#c678dd">interface</span> Log <span style="color:#999999">{</span>
    String <span style="color:#61aeee">value</span><span style="color:#999999">(</span><span style="color:#999999">)</span> <span style="color:#c678dd">default</span> <span style="color:#669900">""</span><span style="color:#999999">;</span>
<span style="color:#999999">}</span>

</code></span>

3、实现切面
