Spring4启动单元测试@ActiveProfiles导致无法加载applicationContext错误

Question

I want to provide different database for running unitTest than using default production database. I thought about using profile to solve this issue. This is spring4 boot project, so everything is annotated. This is what I am doing:

Under src/main/resources, I put application.properties :

spring.datasource.url=jdbc:postgresql://localhost:5432/services
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.datasource.driver-class-name=org.postgresql.Driver

Under src/test/resources, I put application-test.properties

spring.datasource.url=jdbc:postgresql://localhost:5432/services_test
spring.datasource.username=postgres
spring.datasource.password=Hercules1
spring.datasource.driver-class-name=org.postgresql.Driver

Then, I put @ActiveProfiles("test") before test, now when I run the unit test, I immediately meet this error:

java.lang.IllegalStateException: Failed to load ApplicationContext

I googled quite a lot and nothing can solve this error.

Can you point out what's wrong with my solution?

Thanks

Just suffixing -test to application.properties will not make the properties a candidate for the profile that you activate. You need to do the following:

A datasource configuration interface:

public interface DatasourceConfig {
    public void setup();
}

Test Datasource configuration:

@Component
@Profile("test")
public class ProductionDatasourceConfig implements DatasourceConfig {
    @Override
    public void setup() {
        // Set up your test datasource
    }
}

Production datasource configuration:

@Component
@Profile("prod")
public class ProductionDatasourceConfig implements DatasourceConfig {
    @Override
    public void setup() {
        // Set up your prod datasource
    }
}

Activate the profile:

@ActiveProfiles("test")

Inject the datasource based on environment:

@Autowired
DatasourceConfig datasourceConfig;

Beans declared in XML can also be mapped to the profile as below:

<beans profile="dev">
    <bean id="devDatasourceConfig" class="org.profiles.DevDatasourceConfig" />
</beans>

<beans profile="prod">
    <bean id="productionDatasourceConfig" class="org.profiles.ProductionDatasourceConfig" />
</beans>
