html实现页面静态化的案例

public class News { private String title; private String pubTime; private String category; private String newsContent; public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getPubTime() { return pubTime; } public void setPubTime(String pubTime) { this.pubTime = pubTime; } public String getCategory() { return category; } public void setCategory(String category) { this.category = category; } public String getNewsContent() { return newsContent; } public void setNewsContent(String newsContent) { this.newsCOntent= newsContent; }}

自定义流的工具类

public class CharStreamIO { public void copyFile(String fsrc,String fDest){ File file = new File(fDest); if(file.exists()){ file.delete(); } PrintWriter out = null; BufferedReader in = null; try { in = new BufferedReader(new FileReader(fsrc)); out = new PrintWriter(new BufferedWriter(new FileWriter(fDest))); String strRet; while((strRet=in.readLine()) != null){ out.println(strRet); out.flush(); } } catch (Exception e) { e.printStackTrace(); }finally{ if(in != null){ try { in.close(); } catch (Exception e2) { e2.printStackTrace(); } } if(out != null){ try { out.close(); } catch (Exception e2) { e2.printStackTrace(); } } } } /** * 把传入的信息，保存成文件 * @param finfo 传入的文件内容信息 * @param fname 目标路径和文件名 */ public void writeFile(String finfo,String fDest){ File file = new File(fDest); if(file.exists()){ file.delete(); } PrintWriter out = null; try { out = new PrintWriter(new BufferedWriter(new FileWriter(fDest))); out.write(finfo); out.flush(); } catch (Exception e) { e.printStackTrace(); }finally{ if(out !=null){ out.close(); } } } /** * 读取文本型文件 * @param name * @return */ public String readFile(String fname){ File file = new File(fname); StringBuilder bild = new StringBuilder(); BufferedReader in = null; if(file.exists()){ try { in = new BufferedReader(new FileReader(fname)); String strRet; while((strRet=in.readLine()) != null){ bild.append(strRet); } } catch (Exception e) { e.printStackTrace(); }finally{ if(in != null){ try { in.close(); } catch (Exception e2) { e2.printStackTrace(); } } } }else{ System.out.println(fname + "不存在"); } return bild.toString(); }}

数据访问层

public class NewsDao { /** * 读取数据库中要生成的新闻信息 * @return */ public List getAllNews(){ CharStreamIO io = new CharStreamIO(); SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); List newsList = new ArrayList(); News n1 = new News(); n1.setCategory("sport"); String c1 = io.readFile("NewsInfo\\news1.txt"); n1.setNewsContent(c1); n1.setPubTime(sd.format(new Date())); n1.setTitle("深足教练组：说我们买球是侮辱 朱广沪常暗中支招"); News n2 = new News(); n2.setCategory("hot"); String c2 = io.readFile("\\NewsInfo\\news2.txt"); n2.setNewsContent(c2); n2.setPubTime(sd.format(new Date())); n2.setTitle("对对对发发发失误失误"); newsList.add(n1); newsList.add(n2); return newsList; }}

业务逻辑层

public class NewsBiz { /** * 读取数据库中要生成的新闻信息 * @return */ public void createAllNews() throws Exception{ NewsDao dao = new NewsDao(); List newsList = dao.getAllNews(); String destPath = "/News/newspages"; for(int i=0;i

TemplateParam类

public class TemplateParam { public static final String TITLE = "%{title}%"; public static final String CATEGORY = "%{category}%"; public static final String COnTENT= "%{newsContent}%"; public static final String PUB_TIME = "%{pubTime}%";}

用户接口层

public class NewsTest { public static void main(String[] args) { NewsBiz biz = new NewsBiz(); try { biz.createAllNews(); System.out.println("新闻页面创建完毕！"); } catch (Exception e) { e.printStackTrace(); } }}
