十二、AOP 1. 说出Spring的通知类型有哪些？ spring共提供了五种类型的通知： 通知类型 接口 描述 Around 环绕通知 org.aopalliance.intercept.MethodInterceptor 拦截对目标方法调用 Before 前置通知 org.springframework.aop.MethodBeforeAdvice 在目标方法调用前调用 After 后置通知 org.springframework.aop.AfterReturningAdvice 在目标方法调用后调用 Throws 异常通知 org.springframework.aop.ThrowsAdvice 当目标方法抛出异常时调用 前置通知[Before advice]：在连接点前面执行，前置通知不会影响连接点的执行，除非此处抛出异常。 正常返回通知[After returning advice]：在连接点正常执行完成后执行，如果连接点抛出异常，则不会执行。 异常返回通知[After throwing advice]：在连接点抛出异常后执行。 返回通知[After (finally) advice]：在连接点执行完成后执行，不管是正常执行完成，还是抛出异常，都会执行返回通知中的内容。 环绕通知[Around advice]：环绕通知围绕在连接点前后，比如一个方法调用的前后

Spring IOC & AOP

由 故事扮演 提交于 2021-02-10 07:26:50
IOC，控制反转，就是将对象的创建，销毁交由容器来控制，DI，依赖注入，对象的引用由容器来帮忙完成。 AOP面向切面编程，关注的是公共功能，将那一部分代码封装在一起，在运行时，由容器动态织入。如，事务管理，权限控制，日志记录，异常处理。AOP的概念，Pointcut（切点，表达式，用来限制连接点），Join Point（连接点，被拦截的方法），Advice（通知，分为前置通知，环绕通知，后置通知，后置通知又分为正常执行后通知和异常执行后通知），引入（允许对被通知的对象引入新的属性或者方法，实现新功能的同时不影响原来的对象），织入（将通知织入到连接点的过程） https://www.cnblogs.com/boywwj/p/7502185.html 来源： oschina 链接： https://my.oschina.net/u/2308196/blog/3020834
