将H2数据库用于Flyway的Spring测试配置文件

我正在尝试设置我的端到端测试,以使用内存数据库,该数据库可以轻松启动,关闭,擦除和播种测试数据.我正在开发一个spring项目,正在使用flyway迁移数据库.当没有任何配置文件启动我的spring服务器时,flyway正确运行迁移,一切都很好.但是,在我的“测试”配置文件中运行时,不会运行flyway迁移.

application.properties

# Database Properties
spring.jpa.database=POSTGRESQL
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=validate
spring.database.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/mydb

# Data Rest Properties
spring.data.rest.basePath=/api

# Logging Properties
logging.level.root=WARN
logging.level.org.flywaydb=INFO
logging.level.com.myproj=INFO

application-test.properties

# Server Properties
server.port=8081

# Database Properties
spring.jpa.database=H2
spring.database.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:mydb-test

# Dev Tools Properties
spring.devtools.restart.enabled=false

# Flyway Properties
flyway.locations=classpath:db/migration,classpath:db/test_seed_data

这是使用测试配置文件启动spring服务器时获得的输出：

最终的错误是验证失败(当我关闭验证时仍然无法创建表)：

Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing table [table-name]

知道为什么迁移没有针对“测试”配置文件运行吗？

编辑

刚刚意识到我的迁移是用PostgresQL编写的,我希望它们能用H2工作……我认为这显然是一个问题.因此,请将此问题扩展为如何在两种不同的数据库类型上运行相同的迁移(如果可能的话)…

但是为什么我没有收到错误声明Flyway试图运行迁移并且数据库不接受查询？

解决方法:

这个答案基于你的问题更新; “如何在两种不同的数据库类型上运行相同的迁移”.从Flyway FAQ：

What is the best strategy for handling database-specific sql?

Assuming you use Derby in TEST and Oracle in PROD.

You can use the flyway.locations property. It would look like this:

TEST (Derby): flyway.locations=sql/common,sql/derby

PROD (Oracle): flyway.locations=sql/common,sql/oracle

You could then have the common statements (V1__Create_table.sql) in
common and different copies of the DB-specific statements
(V2__Alter_table.sql) in the db-specific locations.

从您的配置看起来您已经拥有了不同的测试数据位置,因此您可以顺利完成任务.在命令行上使用-X打开调试,以查看flyway搜索迁移的方式,以帮助管理这三个目录.我不知道如何从春天开始这样做,这个答案可能会有所帮助：logging-flyway-sql-with-spring-boot.
