AopMethod.java

public void before() { System.out.println("before"); } public void after() { System.out.println("after"); } public void afterReturn() { System.out.println("afterReturn"); } public Object around(ProceedingJoinPoint pjp) { Object result = null; // this.before(call);// 相当于前置通知 try { System.out.println("around before"); //获取对应的处理方法 //参照http://blog.csdn.net/meiyang1990/article/details/50562046 // Signature sig = pjp.getSignature(); // MethodSignature msig = null; // if (!(sig instanceof MethodSignature)) { // throw new IllegalArgumentException("该注解只能用于方法"); // } // msig = (MethodSignature) sig; // Object target = pjp.getTarget(); // Method currentMethod = target.getClass().getMethod(msig.getName(), msig.getParameterTypes()); result = pjp.proceed(); System.out.println("around after"); // this.afterReturn(); // 相当于后置通知 } catch (Throwable e) { // this.afterThrowing(); // 相当于异常抛出后通知 // throw e; } finally { // this.after(); // 相当于最终通知 } return result; }

ICallService.java

java public interface ICallService { void sayHello(); void doNotSayHello(); } 之后提供注解版
