老样子先数据库中反射Cat.java

在前面的配置文件加了springmvc切面所以这边来测试下TestAdvice.java

 1 package com.hpe.advice;
 2 
 3 import org.aspectj.lang.JoinPoint;
 4 import org.aspectj.lang.ProceedingJoinPoint;
 5 
 6 public class TestAdvice {
 7 
 8     // 前置通知
 9     public void before(JoinPoint point) {
10 
11         System.out.println(point.getTarget() + "开始进行log记录---");
12         System.out.println(point.getSignature().getName() + ":方法开始执行");
13         Object obj[] = point.getArgs();
14         if (obj != null) {
15             for (Object objs : obj) {
16                 System.out.println(objs);
17             }
18         }
19     }
20 
21     // 后通知
22     public void after(JoinPoint point) {
23         System.out.println(point.getTarget() + "方法执行结束----");
24 
25     }
26 
27     // 返回后通知
28     public void afterReturn(JoinPoint point, Object ret) {
29         System.out.println(point.getTarget() + "方法执行后的结果为" + ret);
30     }
31 
32     // 抛出异常后通知
33     public void afterThrow(JoinPoint point, Object ex) {
34         System.out.println("异常为" + ex);
35 
36     }
37 
38     // 环绕通知必须又一个参数ProceedingJoinpoint和一个返回值类型
39     public Object around(ProceedingJoinPoint pjp) {
40         Object obj = null;
41 
42         try {
43             // 前置通知
44             System.out.println(pjp.getTarget() + "前置通知开始执行");
45             obj = pjp.proceed();
46             // 返回通知
47             System.out.println(pjp.getSignature().getName() + "方法返回执行结果为：" + obj);
48         } catch (Throwable e) {
49 
50             e.printStackTrace();
51             System.out.println("异常通知开始执行");
52         }
53         // 后置通知
54         System.out.println(pjp.getTarget() + "后置通知-----");
55 
56         return obj;
57 
58     }
59 
60 }
