1、CPU相关信息实体类
/** * CPU相关信息 * * @author csp */ public class Cpu { /** * 核心数 */ private int cpuNum; /** * CPU总的使用率 */ private double total; /** * CPU系统使用率 */ private double sys; /** * CPU用户使用率 */ private double used; /** * CPU当前等待率 */ private double wait; /** * CPU当前空闲率 */ private double free; public int getCpuNum() { return cpuNum; } public void setCpuNum(int cpuNum) { this.cpuNum = cpuNum; } public double getTotal() { return Arith.round(Arith.mul(total, 100), 2); } public void setTotal(double total) { this.total = total; } public double getSys() { return Arith.round(Arith.mul(sys / total, 100), 2); } public void setSys(double sys) { this.sys = sys; } public double getUsed() { return Arith.round(Arith.mul(used / total, 100), 2); } public void setUsed(double used) { this.used = used; } public double getWait() { return Arith.round(Arith.mul(wait / total, 100), 2); } public void setWait(double wait) { this.wait = wait; } public double getFree() { return Arith.round(Arith.mul(free / total, 100), 2); } public void setFree(double free) { this.free = free; } }
2、內存相关信息实体类
/** * 內存相关信息 * * @author csp */ public class Mem { /** * 内存总量 */ private double total; /** * 已用内存 */ private double used; /** * 剩余内存 */ private double free; public double getTotal() { return Arith.div(total, (1024 * 1024 * 1024), 2); } public void setTotal(long total) { this.total = total; } public double getUsed() { return Arith.div(used, (1024 * 1024 * 1024), 2); } public void setUsed(long used) { this.used = used; } public double getFree() { return Arith.div(free, (1024 * 1024 * 1024), 2); } public void setFree(long free) { this.free = free; } public double getUsage() { return Arith.mul(Arith.div(used, total, 4), 100); } }
3、JVM相关信息实体类
/** * JVM相关信息 * * @author csp */ public class Jvm { /** * 当前JVM占用的内存总数(M) */ private double total; /** * JVM最大可用内存总数(M) */ private double max; /** * JVM空闲内存(M) */ private double free; /** * JDK版本 */ private String version; /** * JDK路径 */ private String home; public double getTotal() { return Arith.div(total, (1024 * 1024), 2); } public void setTotal(double total) { this.total = total; } public double getMax() { return Arith.div(max, (1024 * 1024), 2); } public void setMax(double max) { this.max = max; } public double getFree() { return Arith.div(free, (1024 * 1024), 2); } public void setFree(double free) { this.free = free; } public double getUsed() { return Arith.div(total - free, (1024 * 1024), 2); } public double getUsage() { return Arith.mul(Arith.div(total - free, total, 4), 100); } /** * 获取JDK名称 */ public String getName() { return ManagementFactory.getRuntimeMXBean().getVmName(); } public String getVersion() { return version; } public void setVersion(String version) { this.version = version; } public String getHome() { return home; } public void setHome(String home) { this.home = home; } /** * JDK启动时间 */ public String getStartTime() { return DateUtils.parseDateToStr(DateUtils.YYYY_MM_DD_HH_MM_SS, DateUtils.getServerStartDate()); } /** * JDK运行时间 */ public String getRunTime() { return DateUtils.getDatePoor(DateUtils.getNowDate(), DateUtils.getServerStartDate()); } }
这里补上DateUtils工具类，其实自己封装也可以的！

4、主机系统相关信息实体类
/** * 系统相关信息 * * @author csp */ public class Sys { /** * 服务器名称 */ private String computerName; /** * 服务器Ip */ private String computerIp; /** * 项目路径 */ private String userDir; /** * 操作系统 */ private String osName; /** * 系统架构 */ private String osArch; public String getComputerName() { return computerName; } public void setComputerName(String computerName) { this.computerName = computerName; } public String getComputerIp() { return computerIp; } public void setComputerIp(String computerIp) { this.computerIp = computerIp; } public String getUserDir() { return userDir; } public void setUserDir(String userDir) { this.userDir = userDir; } public String getOsName() { return osName; } public void setOsName(String osName) { this.osName = osName; } public String getOsArch() { return osArch; } public void setOsArch(String osArch) { this.osArch = osArch; } }
5、系统文件相关信息实体类
/** * 系统文件相关信息 * * @author csp */ public class SysFile { /** * 盘符路径 */ private String dirName; /** * 盘符类型 */ private String sysTypeName; /** * 文件类型 */ private String typeName; /** * 总大小 */ private String total; /** * 剩余大小 */ private String free; /** * 已经使用量 */ private String used; /** * 资源的使用率 */ private double usage; public String getDirName() { return dirName; } public void setDirName(String dirName) { this.dirName = dirName; } public String getSysTypeName() { return sysTypeName; } public void setSysTypeName(String sysTypeName) { this.sysTypeName = sysTypeName; } public String getTypeName() { return typeName; } public void setTypeName(String typeName) { this.typeName = typeName; } public String getTotal() { return total; } public void setTotal(String total) { this.total = total; } public String getFree() { return free; } public void setFree(String free) { this.free = free; } public String getUsed() { return used; } public void setUsed(String used) { this.used = used; } public double getUsage() { return usage; } public void setUsage(double usage) { this.usage = usage; } }
6、服务器相关信息实体类

7、Controller接口对接前端
/** * 服务器监控 * * @author csp */ @RestController @RequestMapping("/monitor/server") public class ServerController { /** * 获取服务器相关信息 * @return * @throws Exception */ @PreAuthorize("@ss.hasPermi('monitor:server:list')")// Spring Security自定义权限控制注解，不影响结果，可以不加 // AjaxResult 自定义返回结果类，不影响结果，可以自定义 @GetMapping() public AjaxResult getInfo() throws Exception { // 获取服务器相关信息 Server server = new Server(); server.copyTo(); return AjaxResult.success(server); } }
