直接绕过运维，后台查询系统硬件信息

pom.xml 增加oshi-core包

		<!-- 获取系统信息 -->
		<dependency>
			<groupId>com.github.oshi</groupId>
			<artifactId>oshi-core</artifactId>
			<version>3.9.1</version>
		</dependency>
package com.qh.common.controller;

import com.qh.platform.domain.Server;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * 服务器监控
 * 
 * @author ruoyi
 */

@RequestMapping("/monitor/server")
@Controller
public class ServerController extends BaseController
{
    private String prefix = "common/server";

    @RequiresPermissions("monitor:server:list")
    @GetMapping()
    public String server(ModelMap mmap) throws Exception
    {
        Server server = new Server();
        server.copyTo();
        mmap.put("server", server);
        return prefix + "/server";
    }
}

现在来看看显示效果：（本人电脑配置信息就出来了，怎么样是不是配置很强大。做为高级搬砖的，电脑不能怂）

拓展一下：  这 oshi-core 用的版本会比较低 3.9   那么我们根据maven上面版本升级一下

		<dependency>
			<groupId>com.github.oshi</groupId>
			<artifactId>oshi-core</artifactId>
			<version>4.4.0</version>
		</dependency>

这时候就会报错了：

Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: com/sun/jna/platform/win32/VersionHelpers 

根据报错查询问题，一般情况就是项目的jar 版本不一致。然后根据提示的jna/platform这个去找下最新的包。

<dependency>
			<groupId>net.java.dev.jna</groupId>
			<artifactId>jna-platform</artifactId>
			<version>5.5.0</version>
		</dependency>

加了这个包之后 报错信息就不一样了：

Caused by: java.lang.AbstractMethodError: Receiver class com.sun.jna.platform.win32.WinNT$OSVERSIONINFOEX does not define or inherit an implementation of the resolved method abstract getFieldOrder()Ljava/util/List; of abstract class com.sun.jna.Structure.

这个错就更明显   包版本的问题，还是少了一个包。后面找了很多资料  看了一些源码发现这个.jna.platform还有一个包

<dependency>
			<groupId>net.java.dev.jna</groupId>
			<artifactId>jna</artifactId>
			<version>5.5.0</version>
		</dependency>

现在就可以了 ：

最后完整的如下： 因为我自己升级这个版本，网上基本找不到解决办法。自己研究了好一会。记录一下。正常项目不会在后台加这种。服务器的监控也都是运维去做。这个做出来只是针对小公司使用。
