Spring Boot Application not reading application.properties file when using Maven test

Try to define the <resources> tag in the build section in your pom, setting path for resource directory where is application.properties:

<build>        <resources>            <resource>                <directory>resources</directory>                <targetPath>${project.build.outputDirectory}</targetPath>                <includes>                    <include>application.properties</include>                </includes>            </resource>        </resources></build>

You can configure your main datasource as the following, I'm using mysql here. But you can use your own datasource. you can configure the following in your application.properties inside src/main/resources

spring.datasource.url = jdbc:mysql://localhost:3306/dsmspring.datasource.username = rootspring.datasource.password = admin123spring.datasource.testWhileIdle = truespring.datasource.validationQuery = SELECT 1spring.jpa.show-sql = truespring.jpa.hibernate.ddl-auto = updatespring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategyspring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

to run test inside your application you can either use the same datasource or create application-test.properties inside src/test/resources and its possible to configure test data source over there.

Just add the following statement;

@TestPropertySource("classpath:application.properties")

To your test class. I am assuming you have your application.properties file under src/test/resources

Here is my working example;

@RunWith(SpringJUnit4ClassRunner.class)@TestPropertySource("classpath:application.properties")public class TestTwitterFeedRoute extends CamelTestSupport {//...}
