1. Java代码:
public class TestDPara { public static void main(String[] args) { String flag = System.getProperty("Para");
System.err.println(flag);
}
}
2. cmd命令:
java -DPara=sdfdsfdsfdsfsd TestDPara

3. 使用多个参数,如Para、Para1
public class TestDPara { public static void main(String[] args) { String flag = System.getProperty("Para");
System.out.println(flag);
String flag1 = System.getProperty("Para1");
System.out.println(flag1);
}
}
java -DPara=sdfdsfdsfdsfsd -DPara1= TestDPara
执行命令后输出:
