For example, the class path entry foo/*specifies all JAR files in the directory named foo. A classpath entryconsisting simply of * expands to a list of all the jar files in the currentdirectory.A class path entry that contains * will not match class files. To matchboth classes and JAR files in a single directory foo, use either foo;foo/*or foo/*;foo. The order chosen determines whether the classes and resourcesin foo are loaded before JAR files in foo, or vice versa.Subdirectories are not searched recursively. For example, foo/* looks forJAR files only in foo, not in foo/bar, foo/baz, etc.The order in which the JAR files in a directory are enumerated in theexpanded class path is not specified and may vary from platform to platformand even from moment to moment on the same machine. A well-constructedapplication should not depend upon any particular order. If a specific orderis required then the JAR files can be enumerated explicitly in the class path.Expansion of wildcards is done early, prior to the invocation of a program’smain method, rather than late, during the class-loading process itself. Eachelement of the input class path containing a wildcard is replaced by the(possibly empty) sequence of elements generated by enumerating the JAR filesin the named directory. For example, if the directory foo contains a.jar,b.jar, and c.jar, then the class path foo/* is expanded intofoo/a.jar;foo/b.jar;foo/c.jar, and that string would be the value of thesystem property java.class.path.The CLASSPATH environment variable is not treated any differently from the-classpath (or -cp) command-line option. That is, wildcards are honored inall these cases. However, class path wildcards are not honored in the Class-Path jar-manifest header.在windows下这个工作java -cp Test.jar;lib/* my.package.MainClass这不起作用java -cp Test.jar;lib/*.jar my.package.MainClass注意.jar **所以应该单独使用通配符** 。在Linux上以下工作java -cp Test.jar:lib/* my.package.MainClass分隔符是冒号而不是分号。未经作者同意本文严禁转载违者必究
