        System.out.println("after loginServic.login()");
/*ModelAndView就是在view和model中传数据*/
        return new ModelAndView("/helloq", "message", "你好");
    }
}

package service;

public class LoginServiceImpl implements ILoginService {
    public void login() {
        System.out.println("LoginServiceImpl");
    }    
}

package aop;
import java.lang.reflect.Method;
import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;

public class AOPMyTransactionManagerMark_To_Win implements MethodInterceptor {
    public Object invoke(MethodInvocation arg0) throws Throwable {
        System.out.println("模拟start transaction");
        arg0.proceed();
        System.out.println("模拟commit transaction");
        return null;
    }
}

helloq.jsp

<%@ page contentType="text/html; charset=GBK" %>

  
    ${message}
  


输出结果：

模拟start transaction
LoginServiceImpl
模拟commit transaction
after loginServic.login()

补充语法：execution(modifiers-pattern? ret-type-pattern declaring-type-pattern? name-pattern(param-pattern)throws-pattern?)
returning type pattern,name pattern, and parameters pattern是必须的.
ret-type-pattern:可以为*表示任何返回值,全路径的类名等.
name-pattern:指定方法名,*代表所有,set*,代表以set开头的所有方法.
parameters pattern:指定方法参数(声明的类型),(..)代表所有参数,(*)代表一个参数,(*,String)代表第一个参数为任何值,第二个为String类型.
