servlet源码
public class TestServlet extends HttpServlet {
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException {
doPost(request,response);
}
public void doPost(HttpServletRequest request,IOException {
request.setCharacterEncoding("utf-8");
String name = request.getParameter("name");
System.out.println(name );
response.setContentType("text/xml");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
out.print("<mes>success</mes>");
out.close();
}
}
注意事项：
flex的源文件所在目录必须与servlet的根路径相同
例如：flex的文件放在Webroot/user文件夹下，则servlet的路径配置为<url-pattern>/user/TestServlet</url-pattern>
