SSH框架实现登录、新闻增删改查、树形菜单

二、基础base模块
BaseDao

BaseAction
package com.liuwenwu.base.web; import java.io.Serializable; import javax.servlet.ServletContext; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import org.apache.struts2.interceptor.ServletRequestAware; import org.apache.struts2.interceptor.ServletResponseAware; public class BaseAction implements ServletRequestAware, ServletResponseAware,Serializable private static final long serialVersionUID = -7110462505161900879L; /** * 为了传值使用 */ protected HttpServletResponse response; protected HttpServletRequest request; protected HttpSession session; protected ServletContext application; /** * 为了配置跳转页面所用 */ protected final static String SUCCESS = "success"; protected final static String FAIL = "fail"; protected final static String LIST = "list"; protected final static String ADD = "add"; protected final static String EDIT = "edit"; protected final static String DETAIL = "detail"; /** * 具体传值字段 后端向jsp页面传值所用字段 */ protected Object result; protected Object msg; protected int code; public Object getResult() return result; public Object getMsg() return msg; public int getCode() return code; @Override public void setServletResponse(HttpServletResponse arg0) this.response = arg0; @Override public void setServletRequest(HttpServletRequest arg0) this.request = arg0; this.session = arg0.getSession(); this.application = arg0.getServletContext();
