java - 无法让 servlet 打印到文本文件

Question

到目前为止，这是我的代码，希望在没有本地路径的情况下打印它，但它仅在我写入路径时才打印

C:\Users\Javier\Documents\NetBeansProjects\HW5JavierSantana\web\WEB-INF\inputs.txt

似乎无法以任何其他方式使其工作。非常感谢任何和所有的帮助。提前致谢。

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    Writer writer = null;

    String usersLogin = request.getParameter("name");
    String usersTitle = request.getParameter("title");
    String usersName = request.getParameter("username");
    String usersSupervisor = request.getParameter("supervisor");
    String usersPassword = request.getParameter("password");

    response.setContentType("text/plain");

    String file = this.getServletContext().getRealPath("/WEB-INF/inputs.txt");
    System.out.println(file);//<-- prints correct/expected path            
    try{
        writer = new BufferedWriter(new PrintWriter(file));
        writer.write("Employee Info ");
        writer.write(" | UserName: " + usersLogin +
        " | Title: " + usersTitle +
        " | Name: " + usersName +
        " | Supervisor: " + usersSupervisor + 
        " | Password: " + usersPassword);
    } catch (FileNotFoundException e){
        e.printStackTrace();
    } catch (IOException e){
        e.printStackTrace();
    } finally {
        writer.close();
    }

    String url = "/WEB-INF/registered.jsp";
    getServletContext().getRequestDispatcher(url).forward(request, response);

}

日志输出为:

您是否注意到打印路径中的额外构建目录？它不存在于您问题中提到的路径中。
