我有一个关于文件写入权限被拒绝的问题。问题是，当我尝试在 webapps 文件夹下编写文件时，我提出了这个拒绝。但是，我在 /tmp 文件夹上写入相同的文件没有任何问题。我检查了这两者的差异，特别是在一个和每个文件夹的权限上。同 drwxr-xr-x root root /tmp drwxr-xr-x root root /usr drwxr-xr-x root root /usr/share drwxr-xr-x root root /usr/share/tomcat7-examples drwxr-xr -x root root /usr/share/tomcat7-examples/source drwxr-xr-x root root /usr/share/tomcat7-examples/source/webapps drwxr-xr-x root root /usr/share/tomcat7-examples/source /webapps/brain03 drwxr-xr-x root root /usr/share/tomcat7-examples/source/webapps/brain03/WEB-INF drwxr-xr-x root root /usr/share/tomcat7-examples/source/webapps/brain03 /WEB-INF/bbs

为什么我可以通过 /tmp 上的 jsp 页面保存文件而不是 /usr/share/tomcat7-examples/source/webapps/brain03/WEB-INF/bbs？

无论如何，我通过“chown -R tomcat7.tomcat7 /usr/share/tomcat7-examples/source”解决了这个问题。但是，谜底是存在的。每个目录是否有任何特殊的隐藏访问控制标签？

下面是相关的html和jsp源码。

        <META http-equiv="Content-Type" content="text/html;charset=euc-kr">

    <BODY>

    request.setCharacterEncoding("euc-kr"); 
    String name = request.getParameter("NAME");
    String title = request.getParameter("TITLE");
    String content = request.getParameter("CONTENT");
    Date date = new Date();
    Long time = date.getTime();
    String filename = time + ".txt";
    String result;
    PrintWriter writer = null;
    try {
        String filePath = application.getRealPath("/WEB-INF/bbs/" + filename);
        writer = new PrintWriter(filePath);
        writer.printf("Title: %s %n", title);
        writer.printf("Writer: %s %n", name);
        writer.println(content);
        result = "SUCCESS";
    }
    catch (IOException ioe) {
        out.println(ioe.getMessage());
        result = "FAIL";
    }
    finally {
        try {
            writer.close();
        } 
        catch (Exception e) {
        }
    } 
    response.sendRedirect("BBSPostResult.jsp?RESULT=" + result);

String filePath = application.getRealPath("/WEB-INF/bbs/" + filename);

只是猜测，您尝试编写 /WEB-INF 的事实意味着 WEB-INF 位于驱动器的根目录。
