BaseAction基类

在项目当中基类也是必不可少的,定义一个基类,然后它继承你要的那种Action.

并且在基类当中定义一些常用需要的方法,

然后我们只要继承这个基类就可以了.(积累就相当于我们的Action了,我们继承它就可以了)

java 代码

package org.langsin.computer.web.core;

import java.lang.reflect.InvocationTargetException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.commons.beanutils.BeanUtils;
import org.apache.struts.action.ActionForm;
import org.apache.struts.actions.DispatchAction;

public class BaseAction extends DispatchAction {
    /**
     * 将Form里的属性值，通过Java的反射机制全部复制到对象中
     *
     * @param form
     * @param obj
     */
    protected void bindEntity(ActionForm form, Object obj) {
        if (form != null) {
            try {
                BeanUtils.copyProperties(obj, form);
            } catch (IllegalAccessException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

    }

    /**
     * 将对象里的属性值，通过Java的反射机制全部复制到Form中
     *
     * @param form
     * @param obj
     */
    protected void bindForm(ActionForm form, Object obj) {
        if (obj != null) {
            try {
                BeanUtils.copyProperties(form, obj);
            } catch (IllegalAccessException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
    protected Object getSessionObject(HttpServletRequest request,String sessionName){
        Object objSession=null;
        HttpSession session=request.getSession(false);
        if(session!=null){
            objSession=session.getAttribute(sessionName);
        }
        return objSession;
    }
    protected SessionContainer getSessionContainer(HttpServletRequest request){
        SessionContainer sessionContainer=(SessionContainer)this.getSessionObject(request, "SessionContainer");
        if(sessionContainer==null){
             sessionContainer=new SessionContainer();
             sessionContainer.setLocale(request.getLocale());
             HttpSession session=request.getSession(true);
             session.setAttribute("SessionContainer", sessionContainer);
        }
        return sessionContainer;
    }

}
