springboot启动报错,Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

最近在研究springboot, 昨晚写到一半后保存睡觉, 今早一运行报错. 在网上搜索大多数是说配置文件问题, 或者是配置文件的位置问题. 笔者发现在自己的工程中并没有这些问题, 于是又对前一天写的内容进行了一次排查.

发现, 原来是在最后copy了一段代码, 没有改完@RequestMapping("XXX")路径名重复所以报错 -_-! , 修改@RequestMapping("XXX")后正常运行.

出现这么尴尬的错误还真是我粗心的错, 希望对大家有所帮助, 并引以为戒.

第一篇博文, 不太成熟还请见谅 ! ! !
