Issue
.yml file
cassandra:
keyspaceApp:junit
solr:
keyspaceApp:xyz
Bean
@Component
@ConfigurationProperties(prefix="cassandra")
public class CassandraClientNew {
@Value("${keyspaceApp:@null}") private String keyspaceApp;
Main method file
@EnableAutoConfiguration
@ComponentScan
@PropertySource("application.yml")
public class CommonDataApplication {
public static void main(String[] args) {
ConfigurableApplicationContext context = new SpringApplicationBuilder(CommonDataApplication.class)
.web(false).headless(true).main(CommonDataApplication.class).run(args);
}
}
TestCase
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = CommonDataApplication.class)
@IntegrationTest
@EnableConfigurationProperties
public class CassandraClientTest {
@Autowired
CassandraClientNew cassandraClientNew;
@Test
public void test(){
cassandraClientNew.getSession();
System.out.println(" **** done ****");
}
}
Instead of setting junit as the keyspaceApp it sets xyz.
Looks like prefix="cassandra" not working
Solution
It looks like you are trying to use Spring Boot Typesafe Configuration Properties feature.
So in order to have it working correctly, you have to add a few changes to your code:
First of all, your CommonDataApplication class should have @EnableConfigurationProperties annotation e.g.
@EnableAutoConfiguration
@ComponentScan
@PropertySource("application.yml")
@EnableConfigurationProperties
public class CommonDataApplication {
public static void main(String[] args) {
// ...
}
}
I do not believe you need @PropertySource("application.yml") annotation as application.yml (as well as application.properties and application.xml) is a default configuration file used by Spring Boot.
Your CassandraClientNew class does not need to have @Value annotation prefixing keyspaceApp property. And your keyspaceApp has to have a setter method.
@Component
@ConfigurationProperties(prefix="cassandra")
public class CassandraClientNew {
private String keyspaceApp;
public void setKeyspaceApp(final String keyspaceApp) {
this.keyspaceApp = keyspaceApp;
}
}
BTW, if you are using List's or Sets and you initialise collections (e.g. List<String> values = new ArrayList<>();), then only getter is required. If a collection is not initialised then you need to provide a setter method too (otherwise an exception will be thrown).
I hope that will help.
