JSP如何生成静态的html页面?

JSP如何生成静态的html页面?

Answer 1

public class HTMLMaker {
final static Object lock = new Object();
public static void makeHtml(String page, String filePath){
makeHtml(page,filePath,"UTF-8");
}

public static void makeHtml(String page, String filePath,String chartset) {
synchronized (lock) {
HttpURLConnection huc = null;
BufferedReader br = null;
BufferedWriter bw = null;
try {
huc = (HttpURLConnection)new URL(page).openConnection();
System.setProperty("sun.net.client.defaultConnectTimeout", "30000");
System.setProperty("sun.net.client.defaultReadTimeout", "30000");
huc.connect();
InputStream stream = huc.getInputStream();
bw = new BufferedWriter(new OutputStreamWriter (new FileOutputStream(filePath),chartset));
br = new BufferedReader(new InputStreamReader(stream, chartset));
String line;
while((line = br.readLine())!= null){
if(line.trim().length() > 0){
bw.write(line);
bw.newLine();
}
}
}catch (Exception e) {
e.printStackTrace();
}finally {
try {
br.close();
bw.close();
huc.disconnect();
}catch (Exception e) {
e.printStackTrace();
}
}
}
}

}
参数解释:
page:jsp页面的网络地址，比如http://localhost:8080/xxx/index.jsp
filePath：生成的html文件的保存路径
chartset：编码，不填默认utf-8。

思想：
把jsp文件开流读入，再用输出流写入到目标文件。
