在java中使用sshj时ssh时出现问题
我正在尝试远程连接到服务器以执行一些命令。 我对此很陌生，所以开始谷歌搜索。经过一番搜索，我尝试了一下：
我正在使用 sshj0.2.3.jar。
这是我的实现方式：
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
final SSHClient ssh = new SSHClient();
ssh.loadKnownHosts();
ssh.connect("serverName");
try{
ssh.authPublickey("myUserId");
final Session session = ssh.startSession();
try{
final Command cmd = session.exec("net send myMachineName Hello!!!");
System.out.println(cmd.getOutputAsString());
System.out.println("\n Exit Status: "+cmd.getExitStatus());
}finally{
session.close();
}
}finally{
ssh.disconnect();
}
}
}
但我得到以下异常：
Exception in thread "main" java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory
at net.schmizz.sshj.DefaultConfig.(DefaultConfig.java:92)
at net.schmizz.sshj.SSHClient.(SSHClient.java:133)
at SSHTEST.main(SSHTEST.java:24)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:345)
at java.lang.ClassLoader.loadClass(ClassLoader.java:609)
.....
我需要额外的罐子吗，多少额外的罐子我需要吗？我执行正确吗？ 请帮忙。
提前致谢。
I am trying to get a remote connection to server to execute some commands.
I am new to this so started googling. After some search, I gave a try:
I am using sshj0.2.3.jar.
And here is how I implemented it:
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
final SSHClient ssh = new SSHClient();
ssh.loadKnownHosts();
ssh.connect("serverName");
try{
ssh.authPublickey("myUserId");
final Session session = ssh.startSession();
try{
final Command cmd = session.exec("net send myMachineName Hello!!!");
System.out.println(cmd.getOutputAsString());
System.out.println("\n Exit Status: "+cmd.getExitStatus());
}finally{
session.close();
}
}finally{
ssh.disconnect();
}
}
}
But I get the folowing exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory
at net.schmizz.sshj.DefaultConfig.(DefaultConfig.java:92)
at net.schmizz.sshj.SSHClient.(SSHClient.java:133)
at SSHTEST.main(SSHTEST.java:24)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory

at java.lang.ClassLoader.loadClass(ClassLoader.java:609)
.....
Do I need extra jars,How many extra jars do i need. Am I implementing correctly?.
please help.
Thanks in advance.

sshj，第一个结果揭示了答案：From googling
sshj, the first result reveals the answer:是的，您需要 slf4j 的 jar（请参阅 2 页手册）
slf4j 附带API，然后是可插拔的实现，但建议的 slf4j-simple 应该就可以了
Yes, you need the jars for slf4j (see the 2-page manual)
slf4j comes with a API and then a pluggable implementation, but the proposed slf4j-simple should be just fine
slf4j 只是一个外观，您需要提供具体的实现。如果您并不真正关心日志记录，请坚持使用 slf4j 发行版中的 slf4j-nop-$(ver).jar。
slf4j is just a facade, and you need to supply a concrete implementation. If you don't really care about logging, stick in slf4j-nop-$(ver).jar that is present in the slf4j distribution.
