jetty嵌入java project提供http服务

5ol.cc

　　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、[size=1em]ResultServlet [size=1em] 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());
}
}

　　[size=1em] 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[size=1em]request.getParameter的时候被解析成parameter的key；
　　[size=1em]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：

2013-09-18 11:13:20.292:WARN:oeju.UrlEncoded:org.eclipse.jetty.util.Utf8Appendable$NotUtf8Exception: Not valid UTF8! byte E3 in state 2
　　[size=1em]
