spring boot + mybatis 连接 oracle 出现 ORA-00923: 未找到要求的 FROM 关键字 错误

1.原因

hikari 连接池配置错误,mysql和oracle的配置不一样

2.修改

spring:
 datasource:
   hikari:
      connection-test-query: select 1

修改为

spring:
 datasource:
   hikari:
      connection-test-query: select 1 from dual

 

各个数据库的配置:

DataBase     validationQuery
hsqldb     select 1 from INFORMATION_SCHEMA.SYSTEM_USERS
Oracle     select 1 from dual
DB2     select 1 from sysibm.sysdummy1
MySql     select 1
Microsoft SqlServer     select1
postgresql     select version()
ingres     select 1
derby     values 1
H2     select 1
