Spring的嵌入式H2数据源和DB_CLOSE_ON_EXIT [英] Spring’s embedded H2 datasource and DB_CLOSE_ON_EXIT

问题描述

对于单元测试（如果需要，可以调用它们进行集成测试）我在Spring配置中配置了一个嵌入式数据库，如下所示：

For unit tests (call them integration tests if you want) I have configured an embedded database in my Spring config like so:

<jdbc:embedded-database id="dataSource" type="H2">
    <jdbc:script location="classpath:schema_h2.sql" />
</jdbc:embedded-database>

现在，从命令行运行测试时，它们工作正常，但是我遇到了一些错误结束（无害，但有刺激性）：

Now, when running the tests from the command line, they work fine, but I get some errors at the end (harmless, but irritating):

WARN  2013-03-25 12:20:22,656 [Thread-9] o.s.j.d.e.H2EmbeddedDatabaseConfigurer 'Could not shutdown embedded database'
org.h2.jdbc.JdbcSQLException: Database is already closed (to disable automatic closing at VM shutdown, add ";DB_CLOSE_ON_EXIT=FALSE" to the db URL) [90121-170]
    at org.h2.message.DbException.getJdbcSQLException(DbException.java:329) ~[h2-1.3.170.jar:1.3.170]

    at org.springframework.beans.factory.support.DisposableBeanAdapter.destroy(DisposableBeanAdapter.java:238) [spring-beans-3.2.1.RELEASE.jar:3.2.1.RELEASE]

现在包含在e中的提示xception一般很好，但是如何将此属性添加到嵌入式数据源？我是否必须扩展它，手动配置它可以说，添加这样的'高级'功能？

Now the tip contained in the exception is fine in general, but how do I add this attribute to the embedded datasource? Do I have to expand it, configure it by hand so to speak, to add such ‘advanced’ features?

推荐答案

在JDBC URL中指定参数 jdbc：h2：〜/ test; DB_CLOSE_ON_EXIT = FALSE

Specify parameter in JDBC url jdbc:h2:~/test;DB_CLOSE_ON_EXIT=FALSE

同样对于内存测试数据库，我建议你添加 DB_CLOSE_DELAY = -1 ，就像这个：

Also for in-memory test database I suggest you to add DB_CLOSE_DELAY=-1, like this:

jdbc:h2:mem:alm;MODE=Oracle;DB_CLOSE_DELAY=-1

要将JDBC连接URL添加到 embedded-dababase ，请将其更改为：

To add JDBC connection url to embedded-dababase change it to:

<bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
    <property name="driverClass" value="org.h2.Driver"/>
    <property name="url" value="jdbc:h2:mem:test;MODE=Oracle;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE"/>
    <property name="username" value="sa"/>
    <property name="password" value=""/>
</bean>

<jdbc:initialize-database data-source="dataSource" ignore-failures="DROPS">
    <jdbc:script location="classpath:schema_h2.sql" />
 </jdbc:initialize-database>
