在“变量名”中输入CLASSPATH,在“变量值”中输入你的类路径(可以是文件夹路径或JAR文件路径,例如:C:\myproject\lib\*)。 确认并保存。 在Linux/Mac中设置CLASSPATH 在Linux或Mac环境中,可以通过命令行设置CLASSPATH,通常是在终端中输入以下命令: exportCLASSPATH=/path/to/your/classes:/path/to/your/lib/*:...

definedclassesandpackages. The parameter may be set either on thecommand-line, or through anenvironment variable. CLASSPATH是供JVM和java编译器使用,用来查找class,CLASSPATH里的第一个值是“.;”, 也就是先在当前路径下查找类文件; CLASSPATH里也可能有第三方或者自己写的jar文件,意思是可以在这个jar里...
相反,使用JVM自己的-Xbootclasspath选项,以及皮肤-Xbootclasspath/p和-Xbootclasspath/a。 -Xbootclasspath使您可以设置完整的引导类路径(这通常包括一个对rt.jar的引用),以及一些其他JDK附带的(不是 rt.jar的一部分)JAR文件。-Xbootclasspath/p将值前置到现有bootclasspath中,并将 -Xbootclasspath/a附加到...

5. Check the CLASSPATH variable The CLASSPATH variable is one way to tell applications written in the Java programming language (including the SDK tools) where to look for user classes. (The-classpathcommand-line switch is the preferred way.) If your machine does not have the CLASSPATH vari...
