Question

我有关于文件写入权限拒绝的问题。问题是，当我尝试在webapps文件夹下编写文件时，我想到了这种拒绝。但是，我在/ tmp文件夹上写相同的文件没有任何问题。我检查了那两个的差异，特别是在一个和每个文件夹的许可。同样的 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，神秘的立场。每个目录都有特殊的隐藏访问控制标记吗？

以下是相关的html和jsp源代码。

    <HTML>
    <HEAD>
        <META http-equiv="Content-Type" content="text/html;charset=euc-kr">
        <TITLE>BBS Writing</TITLE>
    </HEAD>
    <BODY>
        <H2>Write here</H2>
        <FORM ACTION=BBSPost_new.jsp METHOD=POST>
            Name: <INPUT TYPE=TEXT NAME=NAME><BR>
            Title: <INPUT TYPE=TEXT NAME=TITLE><BR>
            <TEXTAREA COLS=30 ROWS=5 NAME=CONTENT></TEXTAREA><BR>
            <INPUT TYPE=SUBMIT VALUE='Save'>
        </FORM>
    </BODY>
</HTML>

<%@page contentType="text/html; charset=euc-kr"%>
<%@page import="java.io.*, java.util.Date"%>
<%
    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); 
%>

Answer 1

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

只是一个猜测，事实上你正在尝试编写/ WEB-INF意味着WEB-INF是你的驱动器的根源。

jsp无法在webapps上写出权限拒绝文件但/ tmp目录？
