我有一个带有弹簧服务调用的简单 servlet 这里是 doGet 方法

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    System.out.println("==========================TEST=======================");
    logger.info("Inside doGet");

    WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext(this.getServletContext());
    MYServiceIF mYServiceIF= (MYServiceIF) wac.getBean("mYService", MYServiceImpl.class);       
    System.out.println("------------------------" + applicationContext);

    //*********************
    int recordsFetched = mYServiceIF.readInfo();
    //*********************
    logger.info("No ofrecords fetched" + recordsFetched );
    PrintWriter out = response.getWriter();
    out.println("<HTML>");
    out.println("<HEAD>");
    out.println("<TITLE>Servlet Testing</TITLE>");
    out.println("</HEAD>");
    out.println("<BODY>");
    out.println("Welcome to the Servlet Testing Center: No of Records fetched in Service"               + recordsFetched);
    out.println("</BODY>");
    out.println("</HTML>");

}

system.out.println 没有打印任何内容，我在带有数据的网页中获取输出，Sysout 不工作但 out.println 工作可能是什么错误。当我启动本地 JBOSS EAP 6.2 服务器时，会打印启动日志，但之后 Sysout 中没有打印任何内容，但程序正在运行。请帮忙。
