logging:
  level:
    org.jeecg.modules.hdx.mapper: debug

#mybatis plus 设置
mybatis-plus:
  mapper-locations: classpath*:org/jeecg/modules/**/xml/*Mapper.xml
  global-config:
    # 关闭MP3.0自带的banner
    banner: false
    db-config:
      #主键类型  0:"数据库ID自增",1:"该类型为未设置主键类型", 2:"用户输入ID",3:"全局唯一ID (数字类型唯一ID)", 4:"全局唯一ID UUID",5:"字符串全局唯一ID (idWorker 的字符串表示)";
      id-type: 4
      # 默认数据库表下划线命名
      table-underline: true
  configuration:
    # 这个配置会将执行的sql打印出来，在开发或测试的时候可以用

#数据库的配置
spring:
 datasource:
  driver-class-name: com.mysql.cj.jdbc.Driver
  url: jdbc:mysql://localhost:3306/mytest?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT
  username: root

#mybatis的配置
mybatis:
 configuration:
#   sql日志显示，这里使用标准显示
  log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
#  数据库中如果有类似 如  user_name 等命名，会将 _后的字母大写，这里是为了和实体类对应
  map-underscore-to-camel-case: true
#  配置mapper文件的路径
 mapper-locations: classpath:org/jeecg/modules/hdx.mapper/*/mapper/*.xml
 #pageHelper配置分页（官网推荐配置）

 helperDialect: mysql
