#### 3.1 修改前 ####

mybatis:
    #  type-aliases-package: com.wen.system
      mapper-locations: classpath:mapper/**/*.xml
      configuration:
        map-underscore-to-camel-case: true
        log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

#### 3.2 修改后 ####

mybatis:

        map-underscore-to-camel-case: true
        log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
