生成pojo类的java核心代码

public static String createStaticHTMLPage(HttpServletRequest request,
            HttpServletResponse response, ServletContext servletContext,
            String fileFullPath, String jspPath) throws ServletException,
            IOException {
        response.setContentType("text/html;charset=UTF-8");
        RequestDispatcher rd = servletContext.getRequestDispatcher(jspPath);//jspPath为模板的jsp文件名
        final ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        final ServletOutputStream servletOuputStream = new ServletOutputStream() {
            public void write(byte[] b, int off, int len) {
                byteArrayOutputStream.write(b, off, len);
            }

            public void write(int b) {
                byteArrayOutputStream.write(b);
            }
        };
        final PrintWriter printWriter = new PrintWriter(new OutputStreamWriter(
                byteArrayOutputStream, "UTF-8"));
        HttpServletResponse httpServletResponse = new HttpServletResponseWrapper(
                response) {
            public ServletOutputStream getOutputStream() {
                return servletOuputStream;
            }

            public PrintWriter getWriter() {
                return printWriter;
            }
        };
        rd.include(request, httpServletResponse);
        printWriter.flush();
        File codeFile = new File(fileFullPath);//需要生成的pojo的文件,如果BaseUser.java
        FileUtils.createDirAndFile(codeFile);
        FileOutputStream fileOutputStream = new FileOutputStream(codeFile);
        byteArrayOutputStream.writeTo(fileOutputStream);
        fileOutputStream.close();
        return fileFullPath;
        // response.sendRedirect(fileName);
    }
