Springboot+MybatisPlus+Oracle实现主键自增的示例代码

# Mybatis的相关配置
mybatis-plus:
 mapper-locations: classpath*:com/XX/XX/XX/dao/mapping/*.xml
 typeAliasesPackage: com.XX.XX.XX.model
 global-config:
  #主键类型 0:"数据库ID自增", 1:"用户输入ID",2:"全局唯一ID (数字类型唯一ID)", 3:"全局唯一ID UUID";
  id-type: 1
  #序列接口实现类配置
  key-generator: com.baomidou.mybatisplus.incrementer.OracleKeyGenerator
