SFTP Java-管道關閉Jsch異常

發布時間：2024-03-09 00:20:59 作者：網友整理

本文介紹了SFTP Java-管道關閉Jsch異常的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！

問題描述

我正在開發一種將文件從一個位置復制到另一個遠程位置的Java方法。我的代碼如下所示。我嘗試使用jsch 0.1.42&amp；0.1.50&amp；0.1.54

      public static void processFiles(ArrayList<String> FilesToBeCopied, String destFilePath) throws IOException {
        SftpClient client = new SftpClient("karthick");
        String keyFilePath = "/ab/c/d/id_rsa";
        String sftpUser = "karthickkb";
        client.login(sftpUser, keyFilePath, null);
        client.changeWorkingDirectory(destFilePath);
        Configuration conf = new Configuration();
        FileSystem fs = FileSystem.get(conf);
        FSDataInputStream fsdisPath = null;
        String filePath = null;
        for (String sourcefilePath : FilesToBeCopied) {
            try {
                filePath = sourcefilePath;
                Path inputPath = new Path(filePath);
                fsdisPath = fs.open(inputPath);
                BufferedInputStream bis = new BufferedInputStream(fsdisPath);
                client.storeFile(inputPath.getName(), bis);
                fsdisPath.close();
                fsdisPath = null;
            } catch (Exception ex) {
                ex.printStackTrace();
            } finally {
                try {
                    if (client != null) {
                        client.disconnect();


        }
                if (fsdisPath != null) {
                    fsdisPath.close();
                }
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }

}

}

我使用Jsch 0.1.42時的錯誤代碼是
使用jsch 0.1.42時收到以下錯誤代碼。

當我使用jsch 0.1.50時，錯誤如下

Exception in thread "main" java.lang.NoSuchFieldError: identities
    at com.jcraft.jsch.UserAuthPublicKey.start(UserAuthPublicKey.java:39)
    at com.jcraft.jsch.Session.connect(Session.java:463)
    at com.jcraft.jsch.Session.connect(Session.java:183)

我嘗試了足夠多的探索，但我無法為我的問題找到明確的答案，我想我遺漏了一些東西。任何建議都將不勝感激。

使用jsch 0.1.50時維護依賴關系樹

刪除所有其他JSCH庫之后，下面是我的maven，除了0.1.50

之外，我沒有看到任何其他JSCH庫

我仍然在行中出現錯誤

client.login(sftpUser，keyFilePath，null)；

 Actual Log:Exception in thread "main" java.lang.NoSuchFieldError: identities

推薦答案

再次查看您的代碼(就在我喝完咖啡之后，這樣更好)，java.io.IOException: Pipe closed使用JSCH 0.1.42實際上是由您建議的邏輯問題引起的：

您的最終擋路在您的for循環中。作為最后一個擋路，無論是否發生異常，您的客戶端總是在第一次迭代結束時被最后一個擋路斷開連接：

for(...){
    try{
        ...
    }catch(...){
        ...
    }finally{
        # this finally block is inside your for loop
        # finally block is always called whether an exception occur or not
        # on the first iteration, this is called and close your client
        try{
            if(client!=null){
                # nope, it will close the client for next iteration!
                client.disconnect();
            }if(fsdisPath!=null){
                # good to close this however
                fsdisPath.close();
            }
        }catch(Exceptionex){
            ex.printStackTrace();
        }
    }
}

相反，您應該擁有如下內容：

try {
    for(...){
        try{
            ...
        }catch(...){
            ...
        }finally{
            try{
                if(fsdisPath!=null){
                    fsdisPath.close();
                }
            }catch(Exceptionex){
                ex.printStackTrace();
            }
        }
    }
} finally {
    if(client!=null){
        client.disconnect();
    }
}

將for循環作為代碼可見性的函數也可能是個好主意；)

java.lang.NoSuchFieldError: identities是由應用程序的另一部分使用不同的JSch版本引起的，因為您根據Maven依賴關系樹進行了驗證。

在項目(使用jsch 0.1.50)中執行了mvn依賴：tree-dVerose，我發現項目和我已經添加了原始帖子中的所有日志：特別是這個：+-org.mule.transports:mule-transport-sftp:jar:3.4.0:compile[信息]|+-(com.jcraft：jsch：jar：0.1.44-1：COMPILE-由于與0.1.42沖突而省略)+-(com.jcraft：JSCH：JAR：0.1.42：COMPILE-因與0.1.50沖突而省略)[信息]-com.jcraft：jsch：jar：0.1.50：編譯[信息]
