利用Runtime call操作系统的命令,具体的命令取决于不同的操作系统,注意不要调用Runtime.getRuntime().exec(String)接口,要用 Runtime.getRuntime().exec(String[])这个接口,不然复杂命令的执行会有问题。例子如下(拿cpu个数,其他类似): 定义命令: WindowsCmd ="cmd.exe /c echo %NUMBER_OF_PROCESSORS%";//windows的特殊 SolarisCmd = {"/bin/sh", "-c", "/usr/sbin/psrinfo | wc -l"}; AIXCmd = {"/bin/sh", "-c", "/usr/sbin/lsdev -Cc processor | wc -l"}; HPUXCmd = {"/bin/sh", "-c", "echo /"map/" | /usr/sbin/cstm | grep CPU | wc -l "}; LinuxCmd = {"/bin/sh", "-c", "cat /proc/cpuinfo | grep ^process | wc -l"}; 然后判断系统: os = System.getProperty("os.name").toLowerCase(); 根据不同的操作系统call不同的命令。 */ import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.LineNumberReader;
