spring AOP 2.0 实现拦截错误和一些临时功能

spring AOP 2.0 实现拦截异常和一些临时功能

??????????本来是测试网上的例子，看着看着，觉得可以修改的简单一点，说干就干。

1，在Eclispe里面建立一个项目，随便，这叫context吧，使用jdk5的环境。

2，在项目里面加入log4j-1.2.8.jar,commons-logging-1.0.4.jar,cglib-nodep-2.1_3.jar,spring.jar(2.5),aspectweaver.jar,aspecjrt.jar。

3，为了能够在系统中使用log4j，在项目目录下加入log4j.properties，内容

?

10，编写测试类

1. package?phoenics.context.test; ??
2. ??
3. import?org.springframework.context.ApplicationContext; ??
4. import?org.springframework.context.support.FileSystemXmlApplicationContext; ??
5. import?phoenics.context.code.Logic2; ??
6. import?phoenics.context.code.LogicInterface; ??
7. /** ?
8. ?*?@author?phoenics ?
9. ?*?TestAop ?
10. ?*/??
11. public?class?TestAop?{ ??
12. ?public?static?void?main(String[]?args)?throws?InstantiationException,?IllegalAccessException,?ClassNotFoundException?{ ??
13. ????????//通过ApplicationContext获取配置文档 ??
14. ????????ApplicationContext?actx=new?FileSystemXmlApplicationContext("exception_config.xml"); ??
15. ????????LogicInterface?logic1?=?(LogicInterface)actx.getBean("logic1"); ??
16. ????????Logic2?logic2?=?(Logic2)actx.getBean("logic2"); ??
17. ????????//模拟执行新增、修改、删除方法 ??
18. ????????try?{ ??
19. ?????????System.out.println("logic1?starting..."); ??
20. ????????????logic1.doInsert("张三"); ??
21. ????????????logic1.doUpdate("李四"); ??
22. ????????????logic1.doDelete("王五"); ??
23. ????????}?catch?(Exception?ex)?{} ??
24. ????????try?{ ??
25. ?????????System.out.println("logic2?starting...");? ??
26. ????????????logic2.doInsert("张三"); ??
27. ????????????logic2.doUpdate("李四"); ??
28. ????????????logic2.doDelete("王五"); ??
29. ????????}?catch?(Exception?ex)?{} ??
30. ?} ??
31. } ??
32. ??
