本文实例讲述了java获取服务器基本信息的方法。分享给大家供大家参考。具体如下：

利用第三方的jar包：（Hyperic-hq官方网站：http://bined()));// 总的使用率 } // 2.内存资源信息 public void getPhysicalMemory() { // a)物理内存信息 Sigar sigar = new Sigar(); Mem mem; try { mem = sigar.getMem(); // 内存总量 System.out.println("Total = " + mem.getTotal() / 1024L + "K av"); // 当前内存使用量 System.out.println("Used = " + mem.getUsed() / 1024L + "K used"); // 当前内存剩余量 System.out.println("Free = " + mem.getFree() / 1024L + "K free"); // b)系统页面文件交换区信息 Swap swap = sigar.getSwap(); // 交换区总量 System.out.println("Total = " + swap.getTotal() / 1024L + "K av"); // 当前交换区使用量 System.out.println("Used = " + swap.getUsed() / 1024L + "K used"); // 当前交换区剩余量 System.out.println("Free = " + swap.getFree() / 1024L + "K free"); } catch (SigarException e) { e.printStackTrace(); } } // 3.操作系统信息 // a)取到当前操作系统的名称： public String getPlatformName() { String hostname = ""; try { hostname = InetAddress.getLocalHost().getHostName(); } catch (Exception exc) { Sigar sigar = new Sigar(); try { hostname = sigar.getNetInfo().getHostName(); } catch (SigarException e) { hostname = "localhost.unknown"; } finally { sigar.close(); } } return hostname; } // b)取当前操作系统的信息 public void testGetOSInfo() { OperatingSystem OS = OperatingSystem.getInstance(); // 操作系统内核类型如： 386、486、586等x86 System.out.println("OS.getArch() = " + OS.getArch()); System.out.println("OS.getCpuEndian() = " + OS.getCpuEndian());// System.out.println("OS.getDataModel() = " + OS.getDataModel());// // 系统描述 System.out.println("OS.getDescription() = " + OS.getDescription()); System.out.println("OS.getMachine() = " + OS.getMachine());// // 操作系统类型 System.out.println("OS.getName() = " + OS.getName()); System.out.println("OS.getPatchLevel() = " + OS.getPatchLevel());// // 操作系统的卖主 System.out.println("OS.getVendor() = " + OS.getVendor()); // 卖主名称 System.out .println("OS.getVendorCodeName() = " + OS.getVendorCodeName()); // 操作系统名称 System.out.println("OS.getVendorName() = " + OS.getVendorName()); // 操作系统卖主类型 System.out.println("OS.getVendorVersion() = " + OS.getVendorVersion()); // 操作系统的版本号 System.out.println("OS.getVersion() = " + OS.getVersion()); } // c)取当前系统进程表中的用户信息 public void testWho() { try { Sigar sigar = new Sigar(); org.hyperic.sigar.Who[] who = sigar.getWhoList(); if (who != null && who.length > 0) { for (int i = 0; i < who.length; i++) { System.out.println("\n~~~~~~~~~" + String.valueOf(i)+ "~~~~~~~~~"); org.hyperic.sigar.Who _who = who[i]; System.out.println("getDevice() = " + _who.getDevice());

} } // 4.资源信息（主要是硬盘） // a)取硬盘已有的分区及其详细信息（通过sigar.getFileSystemList()来获得FileSystem列表对象，然后对其进行编历）： public void testFileSystemInfo() throws Exception { Sigar sigar = new Sigar(); FileSystem fslist[] = sigar.getFileSystemList(); //String dir = System.getProperty("user.home");// 当前用户文件夹路径 for (int i = 0; i < fslist.length; i++) { System.out.println("\n~~~~~~~~~~" + i + "~~~~~~~~~~"); FileSystem fs = fslist[i]; // 分区的盘符名称 System.out.println("fs.getDevName() = " + fs.getDevName()); // 分区的盘符名称 System.out.println("fs.getDirName() = " + fs.getDirName()); System.out.println("fs.getFlags() = " + fs.getFlags());// // 文件系统类型，比如 FAT32、NTFS System.out.println("fs.getSysTypeName() = " + fs.getSysTypeName()); // 文件系统类型名，比如本地硬盘、光驱、网络文件系统等 System.out.println("fs.getTypeName() = " + fs.getTypeName()); // 文件系统类型 System.out.println("fs.getType() = " + fs.getType()); FileSystemUsage usage = null; try { usage = sigar.getFileSystemUsage(fs.getDirName());

double usePercent = usage.getUsePercent() * 100D; // 文件系统资源的利用率 System.out.println(" Usage = " + usePercent + "%"); break; case 3:// TYPE_NETWORK ：网络 break; case 4:// TYPE_RAM_DISK ：闪存 break; case 5:// TYPE_CDROM ：光驱 break; case 6:// TYPE_SWAP ：页面交换 break; } System.out.println(" DiskReads = " + usage.getDiskReads()); System.out.println(" DiskWrites = " + usage.getDiskWrites()); } return; } // 5.网络信息 // a)当前机器的正式域名 public String getFQDN() { Sigar sigar = null;
