String[] pathNames = {"path1","path2","path3"}; String path = String.join(File.pathSeparator, pathNames); 这里我们在Windows上测试我们的代码。 assertEquals("path1;path2;path3", path); 而文件路径在Linux或Mac上看起来会有所不同。 assertEquals("path1:path2:path3", path); 类似地,我们...
像这样的路径,如果是在java文件中,会需要使用转译符,否则编译会报错。当然使用 File.separator 才是最好的做法。 String str = "cn\\edu\\hdu\\grs\\tdlab\\domain\\hbm\\User.hbm.xml"; String str = "cn\\edu\\hdu\\grs\\tdlab\\domain\\hbm\\User.hbm.xml"; 1. 2. 但在xml配置文件中,没...
