1.输入进入的目录

<body>
<h1>输入读取的目录</h1>
<input id="filePath" name="filePath"/>
<input type="button" value="提交" onclick="location.href='<%=request.getContextPath()%>/logList.jsp?filePath='+encodeURIComponent(encodeURIComponent(document.getElementById('filePath').value))"/>
</body>

2.得到目录列表

<body>
<%
    String filePath =request.getParameter("filePath");
    filePath = URLDecoder.decode(URLDecoder.decode(filePath,"utf-8"), "utf-8");
    File dir = new File(filePath);
    if (dir.exists()) {
        //获取该目录下的所有文件和目录组成的File数组

        File[] files =dir.listFiles();
        //递归遍历每一个子文
        for (File file : files) {
%>
<ahref="<%=request.getContextPath()%>/logDetail.jsp?filePath=<%=URLEncoder.encode(URLEncoder.encode(file.getPath(),"utf-8"),"utf-8")%>"><%=file.getName()%>
</a>;<br>

<%}
%>
<inputtype="button" value="返回上一层" onclick="history.back()">
<%
    }
%>
</body>

3.详情页面,如果是目录进入目录,如果是文件则打开

<body>
<%
    String filePath =request.getParameter("filePath");
    filePath = URLDecoder.decode(URLDecoder.decode(filePath,"utf-8"), "utf-8");
    String fileFullName = filePath;
%>
<h5><%=fileFullName%>
</h5>
<p>
  <%
        File file = new File(fileFullName);

        if (file.exists()) {
            //如果是目录，则：
            if (file.isDirectory()) {

    %>
    <a href="<%=request.getContextPath()%>/logList.jsp?filePath=<%=URLEncoder.encode(URLEncoder.encode(file.getPath(),"utf-8"),"utf-8")%>"><%=file.getName()%>
        <input type="button" value="进入" onclick="history.back()">
            <%
    } else {
        InputStreamReader read = new InputStreamReader(
                new FileInputStream(file), "gbk");//考虑到编码格式
        BufferedReaderbufferedReader = new BufferedReader(read);
        String lineTxt = null;
        while ((lineTxt =bufferedReader.readLine()) != null) {
    %>
            <%=lineTxt%><br>
            <%
            }
            read.close();
         %>
        <input type="button" value="返回上一层" onclick="history.back()">
            <%
        }
    } else {
    %>
        无内容<br>
            <%
        }
    %>
</p>
</body>
