自主配置数据源,mybatis/plus不打印sql日志问题

作者：陈賝

这篇文章主要介绍了自主配置数据源,mybatis/plus不打印sql日志问题,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教

建议使用官方多数据源配置

问题：配置双数据源后不打印sql日志了

看了其他博客，这些配置我都有加

mybatis-plus:
  type-aliases-package: com.lyzw.cloud.common.entity   # 所有Entity别名类所在包
  mapper-locations: classpath:mapper/**/*.xml
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    call-setters-on-nulls: true
    cache-enabled: false

我的问题在配置双数据源后，走默认的mybatis创建工厂，没有各自配置

解决

对比下之前的和之后的

注意注入的
