			Java如何獲取系統(tǒng)cpu、內(nèi)存、硬盤(pán)信息
		
    
		
    　1 概述
    　　前段時(shí)間摸索在Java中怎么獲取系統(tǒng)信息包括cpu、內(nèi)存、硬盤(pán)信息等，剛開(kāi)始使用Java自帶的包進(jìn)行獲取，但這樣獲取的內(nèi)存信息不夠準(zhǔn)確并且容易出現(xiàn)找不到相應(yīng)包等錯(cuò)誤，所以后面使用sigar插件進(jìn)行獲取。下面列舉出了這兩種方式獲取系統(tǒng)信息的方式及代碼。
    　　2 使用Java自帶包獲取系統(tǒng)信息
    　　2.1 使用Java自帶包獲取系統(tǒng)信息代碼如下：
    　　2.1.1 Bytes.java
    public class Bytes {
    public static String substring(String src, int start_idx, int end_idx){
    byte[] b = src.getBytes();
    String tgt = "";
    for(int i=start_idx; i<=end_idx; i++){
    tgt +=(char)b[i];
    }
    return tgt;
    }
    }
    　　2.1.2 IMonitorService.java
    　　public interface IMonitorService {
    　　public MonitorInfoBean getMonitorInfoBean() throws Exception;
    　　}
    　　2.1.3 MonitorInfoBean.java
    public class MonitorInfoBean {
    private long totalMemory;
    private long freeMemory;
    private long maxMemory;
    private String osName;
    private long totalMemorySize;
    private long freePhysicalMemorySize;
    private long usedMemory;
    private int totalThread;
    private double cpuRatio;
    public long getFreeMemory() {
    return freeMemory;
    }
    public void setFreeMemory(long freeMemory) {
    this.freeMemory = freeMemory;
    }
    public long getFreePhysicalMemorySize() {
    return freePhysicalMemorySize;
    }
    public void setFreePhysicalMemorySize(long freePhysicalMemorySize) {
    this.freePhysicalMemorySize = freePhysicalMemorySize;
    }
    public long getMaxMemory() {
    return maxMemory;
    }
    public void setMaxMemory(long maxMemory) {
    this.maxMemory = maxMemory;
    }
    public String getOsName() {
    return osName;
    }
    public void setOsName(String osName) {
    this.osName = osName;
    }
    public long getTotalMemory() {
    return totalMemory;
    }
    public void setTotalMemory(long totalMemory) {
    this.totalMemory = totalMemory;
    }
    public long getTotalMemorySize() {
    return totalMemorySize;
    }
    public void setTotalMemorySize(long totalMemorySize) {
    this.totalMemorySize = totalMemorySize;
    }
    public int getTotalThread() {
    return totalThread;
    }
    public void setTotalThread(int totalThread) {
    this.totalThread = totalThread;
    }
    public long getUsedMemory() {
    return usedMemory;
    }
    public void setUsedMemory(long usedMemory) {
    this.usedMemory = usedMemory;
    }
    public double getCpuRatio() {
    return cpuRatio;
    }
    public void setCpuRatio(double cpuRatio) {
    this.cpuRatio = cpuRatio;
    }
    }

    　　2.2 執(zhí)行結(jié)果如下圖所示：

    　3 使用sigar獲取系統(tǒng)信息
    　　3.1 下載安裝sigar-1.6.4.zip
    　　使用java自帶的包獲取系統(tǒng)數(shù)據(jù)，容易找不到包，尤其是內(nèi)存信息不夠準(zhǔn)確，所以選擇使用sigar獲取系統(tǒng)信息。
    　　解壓壓縮包，將lib下sigar.jar導(dǎo)入eclipse的CLASSPATH中，再將sigar-x86-winnt.dll存入Java的bin目錄即可。
    　　3.2 代碼實(shí)現(xiàn)如下：
