Spring 、
AOP
我的aop 基礎(chǔ)
spring 實際使用 （這就使用一個例子說明）
測試類以及結(jié)果：
package?unit;
import?org.springframework.context.ApplicationContext;
import?org.springframework.context.support.ClassPathXmlApplicationContext;
import?bean.HelloService;
public?class?Main?{
????public?static?void?main(String[]?args)?{
???????????ApplicationContext?context?=?new?ClassPathXmlApplicationContext(??????
???????????????????"beans.xml");????
???????????HelloService?service?=?(HelloService)?context.getBean("helloService");????
???????????service.annotationAop();
???????????
???????????System.out.println();
???????????
???????????service.xmlAop();
???????????
????}
}
結(jié)果：
?annotationAop//正常方法運行
aop--AspectJ!?//annotation攔截
?xmlAop? //正常方法運行
?aop--XmlAop! //配置攔截
use jar- --aspectjrt.jar
- --aspectjweaver.jar
- --acglib-nodep-2.1_3.jar
- --commons-logging.jar
- --spring.jar
- --spring-aspects.jar
