在Java中执行Linux命令，日志都是在命令执行完返回，现在用zt-exec实现日志实时同步输出
第一步：maven中引用zt-exec
<dependency><groupId>org.zeroturnaround</groupId><artifactId>zt-exec</artifactId><version>1.11</version></dependency>
第二步：编写工具类并测试
import com.yeexun.webgl.config.websocket.WebSocketServer;import org.zeroturnaround.exec.ProcessExecutor;import org.zeroturnaround.exec.stream.LogOutputStream;import java.io.IOException;import java.util.UUID;import java.util.concurrent.TimeoutException;/*** @Author 小伍子安* @Date /8/5 16:33* @Version 1.0*/public class ZtExecCommandServer {public static Integer exec(String sid,String... command) throws InterruptedException, TimeoutException, IOException {int exit = new ProcessExecutor().command(command).destroyOnExit().redirectOutput(new LogOutputStream() {@Overrideprotected void processLine(String s) {System.out.println("成功日志："+s);try {WebSocketServer.sendInfo("<span style='color:green;'>"+s+"</span>",sid);} catch (IOException e) {e.printStackTrace();}}}).redirectError(new LogOutputStream() {@Overrideprotected void processLine(String s) {System.out.println("错误日志："+s);try {WebSocketServer.sendInfo("<span style='color:red;'>"+s+"</span>",sid);} catch (IOException e) {e.printStackTrace();}}}).execute().getExitValue();return exit;}public static void main(String[] args) throws InterruptedException, IOException, TimeoutException {exec(UUID.randomUUID().toString(),"ping","");}}
