第一步：添加依赖：

<dependency>
    			<groupId>com.github.oshi</groupId>
    			<artifactId>oshi-core</artifactId>
    			<version>3.9.1</version>
    		</dependency>
    
    		<dependency>
    			<groupId>net.java.dev.jna</groupId>
    			<artifactId>jna</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>net.java.dev.jna</groupId>
    			<artifactId>jna-platform</artifactId>
    		</dependency>

第二步：CPU、内存、虚拟机、系统、系统文件属性基础封装

package com.zzg.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    import com.zzg.monit.domain.Server;
    import io.swagger.annotations.Api;
    import io.swagger.annotations.ApiOperation;
    import lombok.extern.slf4j.Slf4j;
    
    /**
     * 服务器监控
     * @author zzg
     *
     */
    @Api(value = "服务器监控", description = "服务器监控管理")
    @Controller
    @RequestMapping("/server")
    @Slf4j
    public class ServerController {
    	
    	/**服务器监控首页
    	 * @throws Exception **/
        @ApiOperation(value = "服务器监控首页", notes = "服务器监控首页")
        @GetMapping("/server")
        public ModelAndView user() throws Exception{
        	Server server = new Server();
            server.copyTo();
        	ModelAndView modelAndView = new ModelAndView();
        	modelAndView.setViewName("admin/server/server");
        	modelAndView.addObject("server", server);
            return modelAndView;
        }
    	
    
    }
