mybatis-plus在控制台打印SQL语句的⽅法
⽅法⼀、在application.yml添加配置
mybatis-plus:  configuration:
#默认不显⽰SQL⽇志
#    log-impl: org.apache.ibatis.logging.nologging.NoLoggingImpl    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
⽅法⼆、 mapper增加⽇志等级为debug
logging: level:
com.xxx.mapper: debug
mybaits相关配置
mybatis-plus:
mapper-locations: classpath*:cn/demo/**/mapping/*.xml, classpath:/META-INF/modeler-mybatis-mappings/*.xml  configuration:
map-underscore-to-camel-case: true    cache-enabled: true
lazy-loading-enabled: true
multiple-result-sets-enabled: true    #默认不显⽰SQL⽇志
#    log-impl: org.apache.ibatis.logging.nologging.NoLoggingImpl    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl  global-config:    banner: false    db-config:
id-type: assign_id      table-underline: true    enable-sql-runner: true  configuration-properties:    prefix:
