for (OSFileStore fs : fsArray)
{
long free = fs.getUsableSpace();// 磁盘空闲容量
long total = fs.getTotalSpace();// 磁盘总容量
long used = total - free;// 磁盘已使用容量

sysFile.setDirName(fs.getMount());// 磁盘符号 C:\
sysFile.setSysTypeName(fs.getType());// 磁盘类型 NTFS

long mb = kb * 1024;
long gb = mb * 1024;

}
else if (size >= mb)
{
float f = (float) size / mb;
return String.format(f > 100 ? "%.0f MB" : "%.1f MB", f);
}
else if (size >= kb)
{

return String.format(f > 100 ? "%.0f KB" : "%.1f KB", f);
}
else
{
return String.format("%d B", size);
}
}
}7、Controller接口对接前端
@RestController
@RequestMapping("/monitor/server")
public class ServerController
{
@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);
}
