使用 Java 获取电脑性能参数

本文主要是介绍使用 Java 获取电脑性能参数，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Java内置的api 不能直接获取电脑的参数，需要借助第三方工具 oshi

JavaSE 方式

所需要的 jar
com.github.oshi:oshi-core:5.8.0、net.java.dev.jna:jna:5.9.0、net.java.dev.jna:jna-platform:5.9.0
org.slf4j:slf4j-api:1.7.21、org.slf4j:slf4j-simple:1.7.21

实现

package com.test;import oshi.SystemInfo;
import oshi.hardware.CentralProcessor;
import oshi.hardware.GlobalMemory;
import oshi.hardware.HardwareAbstractionLayer;public class SystemInfoTest { public static void main(String[] args) {// 创建 SystemInfo 对象SystemInfo systemInfo = new SystemInfo();// 获取硬件相关信息HardwareAbstractionLayer hardware = systemInfo.getHardware();CentralProcessor processor = hardware.getProcessor();GlobalMemory memory = hardware.getMemory();// 打印 CPU 信息System.out.println("CPU 型号: " + processor.getProcessorIdentifier().getName());// 打印内存信息System.out.println("内存大小: " + memory.getTotal() / (1024L * 1024L) + " MB");// 打印显卡信息System.out.println("显卡信息: " + hardware.getGraphicsCards());// 打印声卡信息System.out.println("声卡信息: " + hardware.getSoundCards());}
}

SpringBoot 方式

所需要的依赖
