AOP面向切面编程：AspectJ：注解开发

String resource = “AspectJapplicationContext.xml”; ApplicationContext applicationContext = new ClassPathXmlApplicationContext(resource); IAspectJService iAspectJService = (IAspectJService) applicationContext.getBean(“aspectJservice”); iAspectJService.doDestroy(); String doFirst = iAspectJService.doFirst(); System.out.println(doFirst);

AspectJapplicationContext.xml配置：

// 前置通知 public void before() { System.out.println(“AspectJ前置通知”); } // 前置通知，带参数（以下任何通知都能带参数，不一一列举） public void before(JoinPoint jp) { System.out.println(“AspectJ前置通知：JP=” + jp); } // 后置通知 public void afterReturning(Object ret) { System.out.println(“AspectJ后置通知：返回结果ret=” + ret); System.out.println("----------------------"); } // 环绕通知 public Object around(ProceedingJoinPoint pjp) throws Throwable { System.out.println(“AspectJ环绕通知：目标方法执行之前通知”); Object proceed = pjp.proceed(); System.out.println(“AspectJ环绕通知：目标方法执行之后通知”); if (proceed != null) { proceed = ((String) proceed).toUpperCase(); } return proceed; } // 异常通知 public void afterThrowing() { System.out.println(“AspectJ异常通知”); } // 异常通知：带参数 public void afterThrowing(Exception ex) { System.out.println(“AspectJ异常通知：ex=” + ex); } // 最终通知 public void after() { System.out.println(“AspectJ最终通知”); }
