创办好的BaseAction

创建好的BaseAction

创建好的 BaseAction , 在其中实现常用的方法,开发就比较轻松.

?

我们项目中实现基本的 request , response 获得,? Json 数据转换 。

?

/** * Action基类 * */public class BaseAction extends ActionSupport implements ServletRequestAware, ServletResponseAware {    /**     * 返回json字符串     */    protected void renderJSON(Map map) {        JSONObject jsonObjectFromMap = JSONObject.fromObject(map);        renderText(jsonObjectFromMap.toString());    }    /**     * 直接输出字符?     */    protected String renderText(String text) {        return render(text, "text/plain;charset=UTF-8");    }    /**     * 直接输出HTML.     */    protected String renderHtml(String html) {        return render(html, "text/html;charset=UTF-8");    }    /**     * 直接输出XML.     */    protected String renderXML(String xml) {        return render(xml, "text/xml;charset=UTF-8");    }/** * Description: 直接输出Text * @param result 输出的内容  removeCache 是否清楚cache * @return  */protected void writeResult(String result, boolean removeCache) {PrintWriter writer = null;try {if(removeCache) {response.setHeader("Pragma", "No-cache");// 清除缓存response.setHeader("Cache-Control", "no-cache");response.setDateHeader("Expires", 0);}response.setContentType("text/html; charset=utf-8");writer = response.getWriter();writer.print(result);writer.flush();} catch (IOException e) {} finally {if (writer != null) {writer.close();}}}@Overridepublic void setServletRequest(HttpServletRequest request) {this.request = request;}@Overridepublic void setServletResponse(HttpServletResponse response) {this.response = response;}}
