jetty嵌入java project提供http服务

1、main函数中启动一个servlet

public static void main(String[] args) throws Exception {  
	    LogUtil.loadLog4J(Constants.log4jPropertyPath);
        Server server = new Server(8080);  
        ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);  
        context.setContextPath("/"); 
        server.setHandler(context);  
        ResultServlet servlet = new ResultServlet();
        ServletHolder holder = new ServletHolder(servlet);
        context.addServlet(holder, "/result");
        server.start();  
        server.join();  
    } 

 2、ResultServlet  extends HttpServlet

    public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        System.out.println("---------:" + request.getCharacterEncoding());
        InputStream is = request.getInputStream();
             InputStreamReader reader = new InputStreamReader(is, "gbk");
             StringWriter writer = new StringWriter();
             char[] buffer = new char[1024];
             int n = 0;
             while (-1 != (n = reader.read(buffer))) {
             writer.write(buffer, 0, n);
             }
             String result = writer.toString();

        String partnerCode = request.getParameter("partnerCode");
        System.out.println("partnerCode:" + partnerCode);
        response.setContentType("text/html;charset=utf-8");
        try {
            String rp = "ok"
            response.setStatus(HttpServletResponse.SC_OK);
            response.getWriter().println(rp);
        } catch (Exception e) {
            LOG.error(e.getMessage());
            response.setStatus(HttpServletResponse.SC_OK);
            response.getWriter().println(e.getMessage());
        }

    }

 建议先从流中读取不带参数post过来的字符串文本，否则如果post的时候没有设置header、Content-Type，将会解析出错,post过来的文本会在request.getParameter的时候被解析成parameter的key；

jetty默认编码格式为utf-8，如果请求的编码格式没有设置，jetty解析的时候会按utf-8解析，有汉字会报警告：
