I am attempting to do unit testing of my DAO (using Spring and Hibernate). I am using HSQLDB per this tutorial. The tutorial states that the in-memory HSQLDB database can be initialized using a SQL script but I cannot find information on how to do so in Spring. Here is the pertinent Spring context config:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="org.hsqldb.jdbcDriver" />
<property name="url" value="jdbc:hsqldb:mem:mydb" />
<property name="username" value="sa" />
<property name="password" value="" />
<property name="initialSize" value="5" />
<property name="maxActive" value="10" />
<property name="poolPreparedStatements" value="true" />
<property name="maxOpenPreparedStatements" value="10" />
</bean>
Any help would be appreciated. Thanks.
If you are trying to work with in-memory databases and Spring, there is a new jdbc
namespace for Spring 3 that makes working with embedded databases very easy.
The best part is that it acts as a DataSource
, so it can easily be dropped in to replace your existing dataSource
bean.
<jdbc:embedded-database id="dataSource" type="HSQL">
<jdbc:script location="classpath:schema.sql"/>
<jdbc:script location="classpath:test-data.sql"/>
</jdbc:embedded-database>
If you are more interested in doing this with Java Config, take a look at the EmbeddedDatabaseBuilder (new in Spring 3.0).
@Configuration
public class DatabaseTestConfig {
@Bean
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder()
.setType(EmbeddedDatabaseType.HSQL)
.addScript("classpath:schema.sql")
.addScript("classpath:test-data.sql")
.build();
}
}
