当时的情况是这样的，我需要在基于Eclipse 3.6+jre6的RCP中调用一个使用jre1.5工具。通过Runtime.exec(command)的方式执行，这个事儿本事很平淡，简单的调用而已。 生成的命令应该是如下的模样：（因为有名称带空格的文件夹，为了偷懒，我把整个路径都用双引号引上了。） cmd /c “c:\Programe Files\Java\jdk1.5\bin\java.exe” -jar aaa.jar -name xxx -file “D:\a.file” 这种做法硬是让我碰到了一个棘手的问题：粘贴到CMD窗口里可以正常执行，但是在代码里就是没法运行。没头苍蝇一样google了一通也没找到合理的解决方法。 最终我决定老老实实的把CMD /?里面的东西看看，果然给我找到解决方法了： 这段文字复制自CMD的帮助文档，详细解释了双引号在命令中的用法 If /C or /K is specified, then the remainder of the command line after the switch is processed as a command line, where the following logic is used to process quote (“) characters: 1. If all of the following conditions are met, then quote characters on the command line are preserved: – no /S switch – exactly two quote characters – no special characters between the two quote characters, where special is one of: &<>()@^| – there are one or more whitespace characters between the the two quote characters – the string between the two quote characters is the name of an executable file. 2. Otherwise, old behavior is to see if the first character is a quote character and if so, strip … Continue reading »
