使用struts1.2
首先在Lisener中设置ServletGroupTemplate相关配置。
模版文件位于WEB-INF/template下
public class InitLisener implements ServletContextListener{
static Log log = LogFactory.getLog(InitLisener.class);
public void contextDestroyed(ServletContextEvent arg0) {
ActionServletContext.destroyed();
}
public void contextInitialized(ServletContextEvent event) {
log.info("加载资源文件");
ServletContext context = event.getServletContext();
String configPath = context.getRealPath("//");
ServletGroupTemplate.intance().init(context);
ServletGroupTemplate.intance().getGroup().config("", "${", "}");
ServletGroupTemplate.intance().getGroup().setCharset("UTF-8");
ServletGroupTemplate.intance().getGroup().registerFunction("fn.substring",new SubStringFunction());
ServletGroupTemplate.intance().getGroup().registerFunction("fn.length",new LengthFunction());
//context.setAttribute("templatepath", context.getRealPath("WEB-INF/template"));
System.out.println(context.getRealPath("WEB-INF/template"));
ActionServletContext.setServletContext(context);
//PropertiesUtil.loadConfig();
}
}
Action类，其中模拟了一些数据，输出路径为跟路径，文件名为index.html
public class StaticPageAction extends Action {
/*
* Generated Methods
*/
/**
* Method execute
*
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
PrintWriter pWriter = null;
ActionForward forward = new ActionForward();
response.setCharacterEncoding("UTF-8");
String templatePath = (String) ActionServletContext.getServletContext()
.getAttribute("templatepath");
String rootpath = ActionServletContext.getServletContext().getRealPath(
"/");
rootpath = rootpath + "/index.html";
List channelList = getNewsData();
try {
pWriter = response.getWriter();
Template template = ServletGroupTemplate.intance().getTemplate(
"/index.html", request, response);
template.set("channelList", channelList);
template.set("user", "chenlei");
template.set("Chal", new Channel(1, "栏目test", "栏目说明", 0, 10, 30));
StringWriter writer = new StringWriter();
template.getText(writer);
// false为从文件开始处写入
OutputStreamWriter outWriter = new OutputStreamWriter(
new FileOutputStream(rootpath, false), "UTF-8");
System.out.println(writer.toString());
Writer out = new BufferedWriter(outWriter);
out.write(writer.toString());
out.flush();
out.close();
pWriter.print("输出首页成功！返回");
} catch (IOException e) {
pWriter.print("输出首页失败！");
} catch (BeeException e) {
// e.printStackTrace();
}
return null;
}
private List getNewsData() {
List newList = new ArrayList(20);
for (int i = 1; i <= 10; i++) {
Channel chnnel = new Channel(i, "栏目" + i, "栏目说明" + i, 0, 10, 30);
for (int j = 1; j <= 11; j++) {
News news = new News(
j + i,
"新闻消息" + j + i,
"新华社消息： 控制语句占位符号是/
你好！${user}
${Chal.chnnelTitle}
${channelList.~size}
栏目列表
${Channel.chnnelTitle}
- [${fn.substring(News.channelTitle,0,2)}…${News.channelTitle} ]-${News.title}---[${News.newdate,dateFormat='yyyy-MM-dd'}]
没有数据
