H2: JdbcSQLException: URL format error

Question

I replaced a configuration which makes a connection to real database with another configuration that should make a connection to in-memory database. I want to use this configuration for integration testing. A simple test looks like this

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class WebApplicationTests {
    @Test
    public void contextLoads() {}
}

New configuration in pom.xml

<profiles>
    <profile>
        <id>IntegrationTest</id>
        <properties>
            <datasource.url>jdbc:h2:mem:db_name_test;MODE=MSSQLServer;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1;INIT=CREATE SCHEMA IF NOT EXISTS db_name_test\\;SET SCHEMA db_name_test</datasource.url>
            <datasource.username>sa</datasource.username>
            <datasource.password></datasource.password>
        </properties>
    </profile>
    <!-- other profiles omitted -->
</profiles>

<dependencies>
    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <version>1.4.195</version>
    </dependency>
    <!-- some dependencies omitted -->
</dependencies>

These properties are injected in resource files and later picked up by Spring during context initialization. Data Source configuration in XML context looks like:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="url" value="${datasource.url}"/>
    <property name="username" value="${datasource.username}"/>
    <property name="password" value="${datasource.password}"/>
</bean>

I use this command to build the project and perform testing:

mvn -T 1C clean integration-test -P IntegrationTest

The test which worked with previous configuration now throws the below exception.

How to fix it?

Answer 1

By the trial and error method I've found that this statement in the connection string is causing the error

\\;SET SCHEMA db_name_test

There's no JdbcSQLException: URL format error exception when it's removed. But I wanted to preserve an application behaviour so instead of deleting the statement I moved it into connectionInitSqls. Also I've specified driverClassName.

Updated Maven profile:

<profile>
    <id>IntegrationTest</id>
    <properties>
        <datasource.driverClassName>org.h2.Driver</datasource.driverClassName>
        <datasource.url>jdbc:h2:mem:db_name_test;MODE=MSSQLServer;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1;INIT=CREATE SCHEMA IF NOT EXISTS db_name_test</datasource.url>
        <datasource.connectionInitSqls>SET SCHEMA db_name_test</datasource.connectionInitSqls>
        <datasource.username>sa</datasource.username>
        <datasource.password></datasource.password>
    </properties>
</profile>

Updated Data Source configuration in XML context:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="${datasource.driverClassName}"/>
    <property name="url" value="${datasource.url}"/>
    <property name="username" value="${datasource.username}"/>
    <property name="password" value="${datasource.password}"/>
    <property name="connectionInitSqls" value="${datasource.connectionInitSqls}"/>
</bean>
