Java如何獲取系統(tǒng)cpu、內(nèi)存、硬盤信息

　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、硬盤信息等，剛開始使用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：
