最近接触的公司产品是基于springboot框架的微服务，我想在本地部署一下，结果各种大坑小坑踩了个遍。docker、springboot、postgresql各种各样的新东西，完全都没有接触过。部署之前，我还一个劲的在找tomcat在哪里呢？部署完也是各种报错，百度都快被我度烂了。
耗了一个多星期，springboot项目还是一启动就报错。数据库问题、网络问题、系统问题、配置文件问题、协助应用问题我排查和解决了一系列问题，最后报错日志终于稳定下来了。

服务一启动就报上面这种bootstrap启动错误，这个应该跟数据库、redis什么的没关系啊，最大可能是包依赖问题。但是研发提供的包没问题啊，已经有安装成功的先例了。我拿我的安装介质对比了安装完成的示例，最后确定除了配置文件不一样，安装介质都是一样的。而且我这还是docker安装啊。
经过众多无效尝试后，我今天试了一下直接在Linux系统中修改jar包配置文件的方法，启动测试一下，发现报错日志终于变了。原来问题出在这啊！毕竟是jar包，跟zip包什么的可能还是不一样的，不能直接在windows系统下直接拖拽文件。当然用jar命令打包估计也是可以的，修改配置文件然后用jar命令重新打包，但我没用这种方法。我用的是vim命令直接修改jar包里面的配置文件。
使用vim命令直接修改jar包里面的配置文件要先安装vim、zip和unzip，要不然Linux不支持这些命令。直接vim xxx.jar，然后用上下方向键移动光标来定位要修改的配置文件，当然也可以用右斜杠查找命令定位要修改的配置文件。定位要修改的配置文件后，按回车键就进入文件修改界面了。其他命令都跟vim编辑器一样。
