当前使用版本(必须填写清楚，否则不予处理)

springBootVersion = '2.1.3.RELEASE' springCloudVersion = 'Greenwich.RELEASE' mybatisPlusVersion = '3.1.0' ctripApolloVersion = '1.4.0' // 携程Apollo配置中心

该问题是怎么引起的？(最新版上已修复的会直接close掉)

重现步骤

mybaits-plus配置

mybatis-plus: mapper-locations: classpath:/mapper/*Mapper.xml global-config: banner: false db-config: id-type: 0 field-strategy: 1 table-underline: true logic-delete-value: 1 logic-not-delete-value: 0 configuration: map-underscore-to-camel-case: true

自己排查

@miemieYaho 有没有点建议？就这样关闭了？

最后debug发现异常

java.lang.IllegalArgumentException: No enum constant com.baomidou.mybatisplus.annotation.FieldStrategy.1

@miemieYaho 请问这里应该如何处理呢

@yuxiaobin 非常感谢，问题解决了，很奇怪的是之前用的spring配置中心没问题，但是使用了携程的apollo配置中心后就出现问题了，mybatis-plus版本依然是3.1.0，没有发生变化。

spring配置中心配置

mybatis-plus:
  mapper-locations: classpath:/mapper/*Mapper.xml
  global-config:
    banner: false
    db-config:
      id-type: 0
      field-strategy: 1
      table-underline: true
      logic-delete-value: 1
      logic-not-delete-value: 0

集成apollo之后配置

mybatis-plus:
  mapper-locations: classpath:/mapper/*Mapper.xml
  global-config:
    banner: false
    db-config:
      id-type: auto
      field-strategy: not_null
      table-underline: true
      logic-delete-value: 1
      logic-not-delete-value: 0

另外一个问题，我这边IDEA没有弹出提示，只有黄色警告，需要怎么做才能有提示？

可能是mp版本问题，请使用最新3.1.2试一下

Comment From: JanWarlen

给后来者提个醒，即便升级到最新3.5.3.1，集成apollo需要在apollo中配置mybatis-plus.global-config.db-config.id-type = auto，哪怕是spring的本地配置文件bootstrap.yml中也是不生效的
