说明：获取的数据是操作系统整体的资源占用情况，不是当前 java进程占用的资源
1. 获取系统CPU占用情况 ：
import java.lang.management.ManagementFactory;
import com.sun.management.OperatingSystemMXBean;
private static OperatingSystemMXBean osmxb = (OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean();
public static int cpuLoad() {
double cpuLoad = osmxb.getSystemCpuLoad();
int percentCpuLoad = (int) (cpuLoad * 100);
return percentCpuLoad;
}
注意：JDK必须是1.8及以上的
返回的值是CPU的百分比，取的是整数值
2. 获取系统内存占用情况
import java.lang.management.ManagementFactory;
import com.sun.management.OperatingSystemMXBean;
private static OperatingSystemMXBean osmxb = (OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean();
public static int memoryLoad() {
double totalvirtualMemory = osmxb.getTotalPhysicalMemorySize();
double freePhysicalMemorySize = osmxb.getFreePhysicalMemorySize();
double value = freePhysicalMemorySize/totalvirtualMemory;
int percentMemoryLoad = (int) ((1-value)*100);
return percentMemoryLoad;
}
注意：JDK为1.6及以上版本
返回的值是内存的百分比，取的是整数值
