以后更新时，先删除原来的证书，然后导入新的证书 查看证书，密钥(yue)口令：changeit
当格式化后，start-dfs.sh。namenode没启动。查看日志。报错例如以下
近期很多小伙伴问我，为何启动项目的时候Spring 或 Spring MVC资源文件找不到 ，这里我总结几个问题出现的原因和解决方案
需要在IDE内获取文件的绝对路径，此处使用copy-absoulte path 发现文件路径内是多出了 \\src
使用 FileReader f = new FileReader(new File("D:\\AAA")); 出现了这个java.io.FileNotFoundException: D:\AAA(拒绝访问...java.io.FileNotFoundException: D:\AAA(拒绝访问。)
我们在使用Java获取文件的时候，如果出现：java.io.FileNotFoundException: E:\data\rocketmqdata\dataDir\checkpoint (拒绝访问。)...出错关键代码： java.io.FileNotFoundException: D:\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps
1、Intellij Idea 这个开发编辑神器（虽然我一点也不喜欢用它），在项目正常启动的时候，如果在你的webapp目录下的空文件夹它是不给你部署的。
