spring 术语和总结

  • 连接点（Joinpoint）
  • 切点（Pointcut）
  • 增强（Advice）
  • 目标对象（Target）
  • 引介（Introduction）
  • 织入（Weaving）
  • 代理（Proxy）
  • 切面（Aspect）

术语太多，没必要一一记住，关键是以下几句话：
Spring AOP通过Pointcut（切点）指定在哪些类的哪些方法上织入横切逻辑，通过Advice（增强）描述横切逻辑和方法的具体织入点（方法前、方法后、方法的两端等）。此外，Spring通过Advisor（切面）将Pointcut和Advice两者组装起来。有了Advisor的信息，Spring就可以利用JDK或CGLib的动态代理技术采用统一的方式为目标Bean创见织入切面的代理对象了。
