APPLICATION FAILED TO START

Description:

A component required a bean of type 'com.trs.mapper.TestMapper' that could not be found.


Action:

Consider defining a bean of type 'com.trs.mapper.TestMapper' in your configuration.

问题出在com.trs.mapper.TestMapper

原因：TestMapper注入有多个，导致内存泄露，

解决办法：在pom.xml先去掉test模块的引入。
