Spring Boot报错：Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

近期学校在学习Java ee，实验要求基于Spring Boot + JSP开发图书管理平台。用idea编写时经常遇到各种各样的问题，都无法好好得到解决。今天便遇见启动Tomcat出错的问题。

查阅网上资料，尝试了各种方法都不能解决我的问题。最后通过修改json jar包的版本，使其成为更高版本，最后问题得以解决，Spring Boot成功启动！

报错：

  1 Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
