运行 Websphere App 服务器 V8.5 Liberty Profile。我找不到任何可以解决这些警告的帮助。我在 eclipse 。

        ************** Here's my servlet code ************
        package com.rocketsoft.zoskmip.kmipuser;

        import java.io.IOException;
        import java.io.PrintWriter;
        import javax.servlet.ServletException;
        import javax.servlet.annotation.WebServlet;
        nhập javax.servlet.http.HttpServlet;
        import javax.servlet.http.HttpServletRequest;
        import javax.servlet.http.HttpServletResponse;
         /**
         * Servlet implementation class AddUser
         */
        @WebServlet("/user")
        public class AddUser extends HttpServlet {
     private static final long serialVersionUID = 1L;

         public AddUser() {
    siêu();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
       throws ServletException, IOException {
    PrintWriter printWriter = response.getWriter();
    printWriter.print("Welcome");
    String firstName = request.getParameter("fname");
    printWriter.print(firstName);
}
}

这些警告看起来很像是您尝试在 Java8 下运行 Liberty Profile。

Liberty profile does not (yet) support Java8 ，据我所知，目前唯一支持的选项是返回到 Java7。
