使用 Java 获取电脑性能参数

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());
    }
}
