文件名包孕空格，在Windows和Linux上JDK的File表现不同

文件名包含空格，在Windows和Linux上JDK的File表现不同

今天在将本地的项目部署到测试服务器上，出现一个Error。追查很久，最终发现原因是配置文件多写了一个空格。这个错误在windows上不会出现，在Linux上会找不到文件。

验证代码如下（realPath是一个以空格结尾的字符串）

logger.info("A: " + realPath + "," + realPath.length() + "," + new File(realPath).exists()); String path = realPath.trim(); logger.info("B: " + path + "," + path.length() + "," + new File(path).exists()); logger.info("+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++");
Linux,运行结果 A: /opt/wf/dsweb/swap.config ,26,false B: /opt/wf/dsweb/swap.config,25,true ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Windows,运行结果 A: E:\opt\wf\dsweb/swap.config ,28,true B: E:\opt\wf\dsweb/swap.config,27,true ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
