自主配置數(shù)據(jù)源,mybatis/plus不打印sql日志問(wèn)題

更新時(shí)間：2023年12月29日 09:31:26 作者：陳賝

這篇文章主要介紹了自主配置數(shù)據(jù)源,mybatis/plus不打印sql日志問(wèn)題,具有很好的參考價(jià)值,希望對(duì)大家有所幫助,如有錯(cuò)誤或未考慮完全的地方,望不吝賜教

問(wèn)題：配置雙數(shù)據(jù)源后不打印sql日志了

看了其他博客，這些配置我都有加

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

我的問(wèn)題在配置雙數(shù)據(jù)源后，走默認(rèn)的mybatis創(chuàng)建工廠，沒(méi)有各自配置

解決

對(duì)比下之前的和之后的

注意注入的

private MybatisPlusInterceptor mybatisPlusInterceptor;
