spring对AOP的支持 采用在配置文件中配置的形式
package zhc.love.dj.test; public interface UserManger { public void addUser(String name,String password); public void delUser(int id) ; public void modUser(int id,String name,String password); }
package zhc.love.dj.test; public class UserMangerImp implements UserManger { public void addUser(String name, String password) { System.out.println("==============UserMangerImp.addUser()==================="); } public void delUser(int id) { System.out.println("==============UserMangerImp.delUser()==================="); } public void modUser(int id, String name, String password) { System.out.println("==============UserMangerImp.modUser()==================="); } }
package zhc.love.dj.test; public interface MySecurtyManger { public void checkSecurity(); }
package zhc.love.dj.test; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; public class MySecurtyMangerImp implements MySecurtyManger { public void checkSecurity() { System.out.println("=========checkSecurity()========="); } }
package zhc.love.dj.test; import org.springframework.beans.factory.BeanFactory; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Client { public static void main(String[] args) { //用spring的类来加载配置文件 BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml"); //通过工厂产生类 调用对应类的id UserManger mangaer = (UserManger)factory.getBean("UserManger"); //mangaer.addUser("zhang", "jingjing"); mangaer.delUser(1); } }

跟上面不同的是这个配置
