记录一次掉坑过程

此次项目我用的是spring boot+mybatis+mysql, 这些都很正常，因为需要调用外部接口，在spring-application.xml里做了些配置，

然后通过@ImportResource实现xml配置的装载，结果项目启动不起来，报错如下：

Description:

The bean 'httpUtils', defined in class path resource [spring-application.xml], could not be registered. A bean with that name has already been defined in file [D:\Git\pst-v2-api\target\classes\com\pst\api\support\util\http\HttpUtils.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true


Process finished with exit code 1

说是名字重复了，简直莫名奇妙，然后就开始各种排查，大概花了一个小时时间，最后在*上找到了答案，

原来springboot 2.1.x 并不支持这种操作，改回到2.0.x，项目正常启动。

希望我的掉坑能给大家一点帮助，特此记录。
