MVC框架实现4---Smart框架Action组件接口设计

Action接口：

package com.smart.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.smart.forwarder.Forwarder;

/**
* Smart框架中Action组件接口
* @author qiaoyupeng
*
*/
public interface Action {

/**Action组件默认调用的方法**/
public Forwarder execute(HttpServletRequest request,HttpServletResponse response);
}


Action抽象类：
package com.smart.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.smart.forwarder.Forwarder;

/**
* Smart框架提供的Action接口抽象实现
* @author qiaoyupeng
*
*/
public abstract class AbstractAction implements Action {

@Override
public Forwarder execute(HttpServletRequest request,
HttpServletResponse response) {
return null;
}

/**execute方法执行前执行，可重写**/
public void init( HttpServletRequest request,HttpServletResponse response){

}

/**execute方法执行后执行，可重写**/
public void destroy(HttpServletRequest request,HttpServletResponse response){

}

}
