可以通过下面的代码获取到 java -D 的系统属性参数列表：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
/** * @author michael * */ public class SystemInfo { /** * @param args */ public static void main(String[] args) { Properties prop = new Properties(System.getProperties()); // 在标准输出中输出系统属性的内容 prop.list(System.out); } } |
测试系统获取到的属性列表如下：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 |
