jsp txt文件下載給我jsp內容

Question

我有一個jsp項目，在我的項目中我想從位置下載一個txt文件。代碼確實有效，但是文件的內容實際上是jsp索引頁面內容，我不喜歡不知道這是怎麼發生的。

String filename = "Teste.txt"; 
    String filepath = "D:\\Online Secure File Transfer System\\project"; 
    response.setContentType("APPLICATION/OCTET-STREAM"); 
    response.setHeader("Content-Disposition","attachment; filename=\"" + filename + "\""); 

    java.io.FileInputStream fileInputStream=new java.io.FileInputStream(filepath + filename); 

    int i; 
    while ((i=fileInputStream.read()) != -1) { 
    out.write(i); 
    } 
    fileInputStream.close(); 

Answer 1

我想與你的文件的路徑問題，不追加字符串

String filename = "Teste.txt"; 
    String filepath = "D:\\Online Secure File Transfer System\\project\\Teste.txt"; 
    response.setContentType("APPLICATION/OCTET-STREAM"); 
    response.setHeader("Content-Disposition","attachment; filename=\"" + filename + "\""); 
    java.io.FileInputStream fileInputStream=new java.io.FileInputStream(filepath); 

    int i; 
    while ((i=fileInputStream.read()) != -1) { 
    out.write(i); 
    } 
    fileInputStream.close();
