java获取服务器信息

java获取服务器信息需要用到sigar.jar，但该jar在linux下依赖于libsigar-amd64-linux.so、libsigar-x86-linux.so。在window下依赖于sigar-amd64-winnt.dll、sigar-x86-winnt.dll。配置文件这存在这模拟系统命名的操作，可以通过这些系统命名来获取系统的参数。

默认情况下是将依赖文件放在jdk下的lib包中，这样项目启动的时候会自动加载这些配置文件。但每个人使用就需要这么配置，太麻烦了，为了方便我们写一个公共类来优化这一问题。

package com.dhcc.isccore.common.util;import java.io.File;import org.hyperic.sigar.Sigar;import com.dhcc.isccore.common.constant.IsccoreConstant;public class SigarUtils {public final static Sigar sigar = initSigar();public static Sigar initSigar() {try {File classPath = new File(IsccoreConstant.SIGAR_PATH);String path = System.getProperty("java.library.path");String sigarLibPath = classPath.getCanonicalPath();// 为防止java.library.path重复加，此处判断了一下if (!path.contains(sigarLibPath)) {if (isOSWin()) {path += ";" + sigarLibPath;} else {path += ":" + sigarLibPath;}System.setProperty("java.library.path", path);}return new Sigar();} catch (Exception e) {return null;}}public static boolean isOSWin() {// OS 版本判断String OS = System.getProperty("os.name").toLowerCase();if (OS.indexOf("win") >= 0) {return true;} elsereturn false;}
}

文件存放位置如下：

jar依赖：

<dependency><groupId>org.hyperic</groupId><artifactId>sigar</artifactId><version>1.6.5.132</version>
</dependency>

获取服务器信息的vo类定义：

package com.dhcc.isccore.entity.serverinfo;import java.util.Date;
import java.util.List;import org.hyperic.sigar.NetInterfaceConfig;public class ServerInfoVo {private String serverIP;       //服务器IPprivate String serverURL;        //服务器Urlprivate String serverType;      //服务器类型private Date serverTime;     //服务器时间private String osName;           //操作系统名称private String osVersion;       //操作系统版本private String userName;        //用户名称private String userHome;      //用户主目录private String osTimeZone;       //操作系统时区private String memTotal;        //物理内存总量private String memUsed;         //已使用的物理内存private String memFree;           //物理内存剩余量private int cpuNum;                //cpu总数private List<CpuInfoVo> cpuList;//cpu信息private int netNum;         //网卡总数private List<NetInterfaceConfig> netList;   //网卡信息private String javaPath;      //java安路径private String javaVendor;     //java运行时供应商private String javaVersion;     //java版本private String javaName;        //java运行时名称private String jvmVersion;       //java虚拟机版本private String jvmTotalMemory;   //java虚拟机总内存private String jvmFreeMemory;   //java虚拟机剩余内存private String databaseType;   //数据库类型private String databaseVersion;  //数据库类型private String databaseDriver;   //数据库驱动private String driverVersion;    //数据库驱动版本private String jdbcUrl;            //数据库连接urlpublic String getServerIP() {return serverIP;}public void setServerIP(String serverIP) {this.serverIP = serverIP;}public String getServerURL() {return serverURL;}public void setServerURL(String serverURL) {this.serverURL = serverURL;}public String getServerType() {return serverType;}public void setServerType(String serverType) {this.serverType = serverType;}public String getOsName() {return osName;}public void setOsName(String osName) {this.osName = osName;}public String getOsVersion() {return osVersion;}public void setOsVersion(String osVersion) {this.osVersion = osVersion;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}public String getUserHome() {return userHome;}public void setUserHome(String userHome) {this.userHome = userHome;}public String getOsTimeZone() {return osTimeZone;}public void setOsTimeZone(String osTimeZone) {this.osTimeZone = osTimeZone;}public String getJavaVendor() {return javaVendor;}public void setJavaVendor(String javaVendor) {this.javaVendor = javaVendor;}public String getJavaVersion() {return javaVersion;}public void setJavaVersion(String javaVersion) {this.javaVersion = javaVersion;}public String getJavaName() {return javaName;}public void setJavaName(String javaName) {this.javaName = javaName;}public String getJvmVersion() {return jvmVersion;}public void setJvmVersion(String jvmVersion) {this.jvmVersion = jvmVersion;}public String getJvmTotalMemory() {return jvmTotalMemory;}public void setJvmTotalMemory(String jvmTotalMemory) {this.jvmTotalMemory = jvmTotalMemory;}public String getJvmFreeMemory() {return jvmFreeMemory;}public void setJvmFreeMemory(String jvmFreeMemory) {this.jvmFreeMemory = jvmFreeMemory;}public String getDatabaseType() {return databaseType;}public void setDatabaseType(String databaseType) {this.databaseType = databaseType;}public String getDatabaseVersion() {return databaseVersion;}public void setDatabaseVersion(String databaseVersion) {this.databaseVersion = databaseVersion;}public String getDatabaseDriver() {return databaseDriver;}public void setDatabaseDriver(String databaseDriver) {this.databaseDriver = databaseDriver;}public String getDriverVersion() {return driverVersion;}public void setDriverVersion(String driverVersion) {this.driverVersion = driverVersion;}public String getJdbcUrl() {return jdbcUrl;}public void setJdbcUrl(String jdbcUrl) {this.jdbcUrl = jdbcUrl;}public Date getServerTime() {return serverTime;}public void setServerTime(Date serverTime) {this.serverTime = serverTime;}public String getJavaPath() {return javaPath;}public void setJavaPath(String javaPath) {this.javaPath = javaPath;}public int getCpuNum() {return cpuNum;}public void setCpuNum(int cpuNum) {this.cpuNum = cpuNum;}public List<CpuInfoVo> getCpuList() {return cpuList;}public void setCpuList(List<CpuInfoVo> cpuList) {this.cpuList = cpuList;}public int getNetNum() {return netNum;}public void setNetNum(int netNum) {this.netNum = netNum;}public List<NetInterfaceConfig> getNetList() {return netList;}public void setNetList(List<NetInterfaceConfig> netList) {this.netList = netList;}public String getMemTotal() {return memTotal;}public void setMemTotal(String memTotal) {this.memTotal = memTotal;}public String getMemUsed() {return memUsed;}public void setMemUsed(String memUsed) {this.memUsed = memUsed;}public String getMemFree() {return memFree;}public void setMemFree(String memFree) {this.memFree = memFree;}}

获取服务器信息的实现类：

public void findServerInfo(BaseAbstractDto baseAbstractDto){try {SigarUtils.initSigar();         //初始化动态库链接路径ServerInfoDto dto = super.getExactlyDto(baseAbstractDto);Properties props=System.getProperties();HttpServletRequest request = ServletActionContext.getRequest();Runtime runTime = Runtime.getRuntime();InetAddress address = InetAddress.getLocalHost();//服务信息ServerInfoVo serverInfoVo = new  ServerInfoVo();InetAddress.getLocalHost().getHostAddress();serverInfoVo.setServerIP(address.getHostAddress());serverInfoVo.setServerURL(request.getScheme()                    //请求头+"://" + address.getHostAddress()  //服务器地址  + ":"   + request.getServerPort()          //端口号  + request.getContextPath());        //项目名称 ServletContext application = request.getSession().getServletContext();serverInfoVo.setServerType(application.getServerInfo());serverInfoVo.setServerTime(new Date());//操作系统serverInfoVo.setOsName(props.getProperty("os.name")+"  "+props.getProperty("os.arch"));serverInfoVo.setOsVersion(props.getProperty("os.version"));serverInfoVo.setUserName(props.getProperty("user.name"));serverInfoVo.setUserHome(props.getProperty("user.home"));Calendar cal = Calendar.getInstance();TimeZone timeZone = cal.getTimeZone();serverInfoVo.setOsTimeZone(timeZone.getDisplayName());//CpuSigar sigar = new Sigar();CpuInfo cpuInfos[] = sigar.getCpuInfoList();serverInfoVo.setCpuNum(cpuInfos.length);CpuPerc cpuList[] = sigar.getCpuPercList();List<CpuInfoVo> cpuVoList = new ArrayList<CpuInfoVo>();for(int m=0;m<cpuList.length;m++){CpuInfoVo cpuInfoVo = new CpuInfoVo();cpuInfoVo.setCpuMhz(cpuInfos[m].getMhz());String cpuIdle = String.format("%.2f",cpuList[m].getIdle()*100)+"%";cpuInfoVo.setCpuLdle(cpuIdle);String cpuCombined = String.format("%.2f",cpuList[m].getCombined()*100)+"%";cpuInfoVo.setCpuCombined(cpuCombined);cpuVoList.add(cpuInfoVo);}serverInfoVo.setCpuList(cpuVoList);//网卡信息String netInfos[] = sigar.getNetInterfaceList();List<NetInterfaceConfig> netList = new ArrayList<NetInterfaceConfig>();for(int i=0;i<netInfos.length;i++){NetInterfaceConfig netInfo = sigar.getNetInterfaceConfig(netInfos[i]); if((NetFlags.LOOPBACK_ADDRESS.equals(netInfo.getAddress()))     //127.0.0.1 || (netInfo.getFlags() == 0)                              //标识为0|| (NetFlags.NULL_HWADDR.equals(netInfo.getHwaddr())) //MAC地址不存在|| (NetFlags.ANY_ADDR.equals(netInfo.getAddress()))       //0.0.0.0){continue;}netList.add(netInfo);}serverInfoVo.setNetNum(netList.size());serverInfoVo.setNetList(netList);//物理内存Mem mem = sigar.getMem();  serverInfoVo.setMemTotal((mem.getTotal()/(1024*1024))+"M");serverInfoVo.setMemUsed((mem.getUsed()/(1024*1024))+"M");serverInfoVo.setMemFree((mem.getFree()/(1024*1024))+"M");//java配置serverInfoVo.setJavaPath(props.getProperty("java.home"));serverInfoVo.setJavaVendor(props.getProperty("java.vendor"));serverInfoVo.setJavaVersion(props.getProperty("java.version"));serverInfoVo.setJavaName(props.getProperty("java.specification.name"));serverInfoVo.setJvmVersion(props.getProperty("java.vm.version"));serverInfoVo.setJvmTotalMemory((int)(runTime.totalMemory()/(1024*1024))+"M");serverInfoVo.setJvmFreeMemory((int)(runTime.freeMemory()/(1024*1024))+"M");//数据库信息findDatabase(serverInfoVo);dto.setServerInfoVo(serverInfoVo);} catch (Exception e) {e.printStackTrace();}
}//数据库连接信息
public void findDatabase(ServerInfoVo serverInfoVo){try{PropertiesUtil propertiesUtil = PropertiesUtil.getInstance("hibernate.properties");//读取配置文件的连接信息String driver = propertiesUtil.getProperty("jdbc.driver");String jdbcUrl = propertiesUtil.getProperty("jdbc.url");serverInfoVo.setJdbcUrl(jdbcUrl);String username = propertiesUtil.getProperty("jdbc.username");String password = propertiesUtil.getProperty("jdbc.password");Class.forName(driver);Connection con = (Connection) DriverManager.getConnection(jdbcUrl,username,password);DatabaseMetaData metaData = (DatabaseMetaData) con.getMetaData();serverInfoVo.setDatabaseType(metaData.getDatabaseProductName());serverInfoVo.setDatabaseVersion(metaData.getDatabaseProductVersion());serverInfoVo.setDatabaseDriver(metaData.getDriverName());serverInfoVo.setDriverVersion(metaData.getDriverVersion());}catch(Exception e){e.printStackTrace();}
}

显示效果如下：
