[转]使用servlet把JSP生成html -- 风信Java论坛 -- Powered by JavaWind.Net

1、ToHtml.java(不用修改,直接用)，注意包名即可

运行复制保存 java代码

package com.jetsum.mystatic;
import java.io.ByteArrayOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponseWrapper;
public class ToHtml extends HttpServlet {
public void service(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String url = request.getParameter("urls") != null ? request.getParameter("urls") : "";
// url是要生成htm的jsp页面
String name = "";
response.setContentType("text/html;charset=gb2312");
ServletContext sc = getServletContext();
System.out.println("request.getRealPath" + request.getRealPath(""));
name = request.getRealPath("") + "/index.htm";
RequestDispatcher rd = sc.getRequestDispatcher(url);
final ByteArrayOutputStream os = new ByteArrayOutputStream();
final ServletOutputStream stream = new ServletOutputStream() {
public void write(byte[] data, int offset, int length) {
os.write(data, offset, length);
}
public void write(int b) throws IOException {
os.write(b);
}
};
final PrintWriter pw = new PrintWriter(new OutputStreamWriter(os));
HttpServletResponse rep = new HttpServletResponseWrapper(response) {
public ServletOutputStream getOutputStream() {
return stream;
}
public PrintWriter getWriter() {
return pw;
}
};
rd.include(request, rep);
pw.flush();
FileOutputStream fos = new FileOutputStream(name); // 把jsp输出的内容写到xxx.htm
os.writeTo(fos);
fos.close();
PrintWriter out = response.getWriter();
out.print("<p align=center><font size=3 color=red>首页已经成功生成！</font></p>");
}
}

2、web.xml
中添加
<servlet>
<servlet-name>tohtml</servlet-name>
<servlet-class>com.jetsum.mystatic.ToHtml</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>tohtml</servlet-name>
<url-pattern>/web/tohtml</url-pattern>
</servlet-mapping>

3、使用方法很简单 mytest.jsp(wwwroot下)
<a href="web/tohtml?urls=/kszx/kszx.jsp">生成静态页</a> kszx.jsp为要生成htm的动态页

如果不在wwwroot下，在wwwroot/pp下，就要写成
<a href="../web/tohtml?urls=/kszx/kszx.jsp">生成静态页</a>
