法律研究从 Java 中的 RuntimeMXBean 获取启动路径
RuntimeMXBean 在 Java 虚拟机运行时系统的管理接口中。
RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();
要获取启动路径，请使用 getBootClassPath() 方法 −
runtimeMX.getBootClassPath()
以下是一个示例 −
示例
import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
import java.util.Date;
public class Demo {
public static void main(String args[]) throws Exception {
RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();
System.out.println("Class path = "+runtimeMX.getClassPath());
System.out.println("Boot Class path = "+runtimeMX.getBootClassPath());
}
}输出
Class path = /home/cg/root/GNUstep/Library/Libraries/Java:/usr/GNUstep/Local/Library/Libraries/Java:/usr/GNUstep/System/ Library/Libraries/Java::/usr/share/java/mysql-connector-java.jar:.:/var/www/html/lib:/var/www/html/lib/dom4j- 1.6.jar:/var/www/html/lib/guava-18.0.jar:/var/www/html/lib/jackson-all.jar:/var/www/html/lib/jaxen- 1.1.4.jar:/var/www/html/lib/jcommon.jar:/var/www/html/lib/jdom2- 2.0.5.jar:/var/www/html/lib/jfreechart.jar:/var/www/html/lib/junit-4.12.jar:/var/www/html/lib/spymemcached- 2.10.3.jar:/var/www/html/lib/stax-1.2.0.jar:/var/www/html/lib/xstream-1.4.7.jar:/var/www/html/lib/gson- 2.3.1.jar:/var/www/html/lib/hamcrest-core-1.3.jar Boot Class path = /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141- 1.b16.fc26.x86_64/jre/lib/resources.jar:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141- 1.b16.fc26.x86_64/jre/lib/rt.jar:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141- 1.b16.fc26.x86_64/jre/lib/sunrsasign.jar:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141- 1.b16.fc26.x86_64/jre/lib/jsse.jar:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141- 1.b16.fc26.x86_64/jre/lib/jce.jar:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141- 1.b16.fc26.x86_64/jre/lib/charsets.jar:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141- 1.b16.fc26.x86_64/jre/lib/jfr.jar:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.141-1.b16.fc26.x86_64/jre/classes
