Java獲取JVM參數(shù)要怎么實現(xiàn)？動力節(jié)點小編來告訴大家實現(xiàn)思路:

使用 ManagementFactory.getRuntimeMXBean() 中的getInputArguments()方法即可獲取JVM運(yùn)行時的參數(shù)

package com.java265.other;
import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
import java.util.List;
public class Test01 {
    /*
     * java265.com 示例程序
     */
    public static void main(String[] args) {
        RuntimeMXBean bean = ManagementFactory.getRuntimeMXBean();
        List<String> aList = bean.getInputArguments();
        for (int i = 0; i < aList.size(); i++) {
            System.out.println(aList.get(i));
        }
    }
}

運(yùn)行以上代碼，將輸出以下信息
