Java连接Linux系统执行命令并且获取返回信息

[qq_36256339]

我用的jsch 大概代码如下（手打大家凑合看）：

    String user = “123”；
    String psw = "123";
    JSch jsch = new JSch();
    session = jsch.getSession(user, ip, 22);
    session.setPassword(psw);
    session.setConfig("StrictHostKeyChecking", "no");
    session.connect();
    ChannelExec channelExec = (ChannelExec)session.opeanChannel(("exec");
    channelExec.setCommand("echo `env`");
    channelExec.connect();
    InputStream in = channelExce.getInputStream();
    bufferedReader reader = new BufferedReader(new InputStreamReader(in,Charset.forName("ntf-8")));
    String bug = null;
    StringBuffer sb = new StringBuffer();
while((buf = reader.readLine()!=null){
    sb.append(buf);
    System,out.println(sb);
}
    reader.close();
    if(channelExec.isClosed&&channelExec!=null{
    channelExec.disconnect();
}
if(session!=null&&session.isConnected()){
session.disconnect();
 

Eclipse 后台输出：


CRT上的实际的信息：



为什么会有这种结果 对比了一下，有一些值没有读取到，求大神指点一下！

如果用printStream打印命令的话 会获取全部信息，但是还有一些多余的信息

代码错误太多 整理后的 public static void main(String[] args) throws Exception{ JSch jsch = new JSch(); Session session = jsch.getSession("root", "192.168.56.113", 22); session.setPassword("123qwe"); session.setConfig("StrictHostKeyChecking", "no"); session.connect(); ChannelExec channelExec = (ChannelExec)session.openChannel("exec"); channelExec.setCommand("ps -ef|grep java"); channelExec.connect(); InputStream in = channelExec.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(in,Charset.forName("utf-8"))); String buf = null; StringBuffer sb = new StringBuffer(); while((buf = reader.readLine())!=null){ sb.append(buf); System.out.println(sb); } reader.close(); if(channelExec.isClosed()&&channelExec!=null){ channelExec.disconnect(); } if(session!=null&&session.isConnected()){ session.disconnect(); } }
