内存中的Spring引导飞行道H2：由：org.H2.jdbc引起。JdbcSQLException：找不到表“xxxx”；SQL语句：

Question

我在Spring启动项目中使用H2作为内存数据库进行单元测试。但是，我得到以下错误

按配置如下

spring.datasource.url =jdbc:h2:mem:test;DB_CLOSE_ON_EXIT=FALSE;AUTO_RECONNECT=TRUE;DATABASE_TO_UPPER=false;INIT=create schema if not exists test;
spring.datasource.username = sa
spring.datasource.password =
spring.datasource.driverClassName = org.h2.Driver

# Specify the DBMS
spring.jpa.database =

# Show or not log for each sql query
spring.jpa.show-sql = false



#flyway.check-location=true
flyway.locations=classpath:db/migration/mysql
flyway.schemas=test

Answer 1

尝试在test.properties:

spring.datasource.url = jdbc:h2:mem:DBNAME
spring.datasource.username = sa
spring.flyway.url = jdbc:h2:mem:DBNAME
spring.flyway.baseline-on-migrate = true

Answer 2

这是一个非常古老的问题，但我刚刚在2021年遇到了同样的问题。我设法通过将DB_CLOSE_DELAY=-1添加到连接字符串来解决这个问题，如下所示：

这是我的申请。

spring:
  flyway:
    url: jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1
    baseline-on-migrate: true
    user: sa
    password:

Answer 3

结合Spring启动，飞行方式和H2，我有一些模拟问题，可以在默认的公共架构以外的其他架构中查找表。

我解决这个问题的方法是：

>

添加为第一个脚本V1.0.1__create_schema.sql

create schema if not exists test;  

在过程、函数和语句中使用allways完整限定符

create table test.my_table;

或者改为使用测试数据库的H2默认模式。

 flyway.schemas=PUBLIC
