HycTest.java

public class HycTest{
    public static void main(String[] args) throws Throwable {
        System.out.println("打包成功！");
    }
}

执行maven->clean->package

在target将hycCall.jar移动到lib文件夹下，此时lib文件夹和hycCal-testl.jar就是可以执行的jar包了

命令行

// 命令行debug模式(-Xms4G -Xmx8G -XX:PermSize=4G -XX:MaxPermSize=8G为指定内存大小)
java -Xdebug -Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=y -jar -Xms4G -Xmx8G -XX:PermSize=4G -XX:MaxPermSize=8G -Djava.ext.dirs=./lib mist-calculate-1.0-test.jar

// 后台执行模式(nohup xxx &)
nohup java -jar -Xms4G -Xmx8G -XX:PermSize=4G -XX:MaxPermSize=8G -Djava.ext.dirs=./lib mist-calculate-1.0-test.jar &

// 日志查看
tail -10f nohup.out

// 查看java命令的进程
ps -a | grep java

// 杀死指定线程号
kill -9  线程号
