与Flyway/Spring和H2嵌入式数据库相关的模式问题

与Flyway/Spring和H2嵌入式数据库相关的模式问题

我正在构建一个使用MySQL数据库的Spring 3 MVC应用程序,并且最近将Flyway集成到解决方案中以管理数据库迁移.我已根据Flyway文档成功配置了我的applicationContext.xml,以便在应用程序启动时,Flyway将迁移到最新版本.

我无法让Flyway与我的单元/功能测试很好地配合使用.我使用Spring Data JPA作为我的数据访问层,并构建了一些JUnit测试来测试一些自定义查询.

我用于这些测试的应用程序配置是:

<jdbc:embedded-database id="dataSource" type="H2" />

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
  <property name="driverClassName" value="org.h2.Driver"/>
  <property name="url" value="jdbc:h2:mem:medical_claims_tracker;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1;MODE=MySQL;INIT=CREATE SCHEMA IF NOT EXISTS medical_claims_tracker" />
</bean>

<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate">
    <property name="dataSource" ref="dataSource"/>
    <property name="schemas" value="medical_claims_tracker"/>
    <property name="sqlMigrationPrefix" value="Migration_"/>
</bean>

当我运行单元测试时(通过Eclipse或使用Maven),我得到以下异常:

I can't work out how to get the H2 database to recognise the fact that I want to use a schema called medical_claims_tracker. I used this answer to help me try out different connection URLs and this answer to help me nail down the applicationContext overrides for use during testing.

I suspect it is something to do with H2 dropping the schema after initial creation but before the test can be run, but I thought that DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1; would solve that for me. Interestingly, if I remove the specification of the schema in the flyway bean config:

<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate">
    <property name="dataSource" ref="dataSource"/>
    <property name="sqlMigrationPrefix" value="Migration_"/>
</bean>

So it seems that with the first configuration, Flyway is able to create the schema_version table in the medical_claims_tracker schema but can't then find that schema to run the tests in, whereas in the second version, it can't even find the "default" schema in which to create the schema_version table. Is this correct, or have I got this the wrong way round?

Answer 1

Omi*_*mid 13

来自http://www.h2database.com/javadoc/org/h2/engine/DbSettings.html:

databaseToUpper:数据库设置DATABASE_TO_UPPER(默认值:true).

数据库短名称将转换为DATABASE()函数的大写 ... 将此设置为"false"是实验性的.设置为false时,所有标识符名称(表名,列名)都区分大小写 ...

问题是默认情况下模式名称是大写的.

解:

添加;DATABASE_TO_UPPER=false到数据库URL

Answer 2

Tom*_*Tom 12

从我测试的结果来看,整个问题只发生在将flyway和H2与MySql兼容模式混合时(如果是MySql模式则不会发生).它是由区分大小写不一致引起的:

初始化期间h2创建默认架构'PUBLIC'(大写!)
当flyway尝试获取默认模式名称时,它会变为"公共"(小写!)
当flyway尝试将当前架构更改为"public"(小写!)时会抛出错误.即使将飞路模式设置为"MYSCHEMA",在迁移过程的某个阶段,它总是会尝试更改为"公共".

在我目前开发的应用程序中,我们使用MySql作为主数据库,使用H2进行测试.我的解决方法涉及在h2初始化期间创建'public'(小写!)模式:
