使用pojo+xml开发aop案例

定义一个接口
public interface EmployeeService {
public void work();
public void work(String name,String pass);
}
新建一个实体类实现上述接口
public class EmployeeServiceBean implements EmployeeService{
@Override
public void work() {
//int i=1/0;
System.out.println("++++++++++++++++++工作中+++++++++++++++++");
}
@Override
public void work(String name,String pass) {
//int i=1/0;
System.out.println("++++++++++++++++++带参数的工作中+++++++++++++++++");
}
}
定义一个切面类
public class AdviceUtil {
//具体通知-------进行安全检测
public void checkLogin(String name,String pass){
System.out.println("检查用户登录的用户名和密码。。。。。。。。。。。。");
}
//通知
public void goHome(){
System.out.println("...............回家................");
}
//通知
public void getUp(){
System.out.println("...............起床................");
}
//通知
public Object punchCard(ProceedingJoinPoint jp) throws Throwable{
System.out.println("===============上班打卡================");
Object obj=jp.proceed();
System.out.println("===============下班打卡================");
return obj;
}
//通知
public void back(){
System.out.println("===============back方法================");
}
//通知
public void unWell(Exception ex){
System.out.println("===============unWell方法================"+ex.getMessage());
}
}
在xml文件中配置
