我正在研究一种将文件从一个位置复制到另一个远程位置的java方法。我的代码如下。我尝试使用 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();
}
}
}
}
}
使用Jsch 0.1.42时的错误代码是 我使用jsch 0.1.42时收到以下错误代码。

当我使用jsch 0.1.50时，错误如下
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)
我试图进行足够的探索，但我无法得到一个明确的问题答案，我想我错过了一些东西。任何建议将不胜感激。
当我使用 jsch 0.1.50 时，Maven依赖树

答案 0 :(得分：4)
第二次查看你的代码（在我的咖啡之后，它更好），java.io.IOException: Pipe closed与JSch 0.1.42实际上是由你建议的逻辑问题引起的：
你的finally块是里面你的for循环。因为始终调用finally块，无论是否发生异常，客户端总是在第一个iteraton末尾的finally块中断开连接：
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，你应该有类似的东西：
try {
for(...){
try{
...
}catch(...){
...
}finally{
try{
if(fsdisPath!=null){
fsdisPath.close();
}
}catch(Exceptionex){
ex.printStackTrace();
}
}
}
} finally {
if(client!=null){
client.disconnect();
}
}
将for循环作为代码可用性的函数也可能是个好主意;）
java.lang.NoSuchFieldError: identities是由您使用不同JSch版本的另一个应用程序引起的，因为您根据Maven依赖关系树进行了证据。
做了一个mvn依赖：tree -Dverbose在项目中（使用jsch 0.1.50）我发现该项目和我在原帖中添加了所有日志：特别是：+ - org.mule.transports： mule-transport-sftp：jar：3.4.0：编译[INFO] | + - （com.jcraft：jsch：jar：0.1.44-1：compile - 与0.1.42冲突省略）+ - （com.jcraft：jsch：jar：0.1.42：compile - 省略与0.1的冲突。 50）[INFO] - com.jcraft：jsch：jar：0.1.50：编译[INFO]
答案 1 :(得分：0)
看起来像服务器问题。您确定要连接的用户是否具有写入权限？您的SFTP服务器是否可以访问？看一下这篇文章：com.jcraft.jsch.JSchException: java.io.IOException: Pipe closed
同时检查你的ssh服务器日志，你可能会有一些有用的东西。
