Spring-boot with Liquibase Overloading Property - spring-boot

Question

I am using Spring boot and Liquibase.
Using this url as guidelines
http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/
In pom.xml, the below entry is present so that spring boot knows about liquibase.
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
</dependency>
and put the changelog file in resources folder.
db.changelog-master.xml
Now Spring boot first tring to find db.changelog-master.yaml in classpath and throwing the exception like this.
Cannot find changelog location: class path resource [db/changelog/db.changelog-master.yaml
To Fix the Issue, I have added the bean like below in my class and tried to set changeLog proprty.
#Configuration
#ComponentScan
#EnableAutoConfiguration
public class SampleDataJpaApplication {
#Autowired
LiquibaseProperties properties;
#Autowired
private DataSource dataSource;
#Bean
public SpringLiquibase liquibase() {
SpringLiquibase liquibase = new SpringLiquibase();
properties.setChangeLog("classpath:/db/changelog/db.changelog-master.xml");
liquibase.setChangeLog(this.properties.getChangeLog());
liquibase.setContexts(this.properties.getContexts());
liquibase.setDataSource(this.dataSource);
liquibase.setDefaultSchema(this.properties.getDefaultSchema());
liquibase.setDropFirst(this.properties.isDropFirst());
liquibase.setShouldRun(this.properties.isEnabled());
return liquibase;
}
public static void main(String[] args) throws Exception {
Logger logger = LoggerFactory.getLogger("SampleDataJpaApplication");
SpringApplication springApplication = new SpringApplication();
springApplication.run(SampleDataJpaApplication.class, args);
}
}
but it is failing with the message.
org.springframework.beans.factory.BeanCreationException: Error
creating bean with name 'sampleDataJpaApplication': Injection of
autowired dependencies failed; nested exception is
org.springframework.beans.factory.BeanCreationException: Could not

Please provide the inputs here, why i am getting this exception or Is there any any other available way to override the same class so that i can change the changeLog property of liquibase properties.

I'm not entirely sure what the exact runtime path to your change log is, but why don't you just use the "liquibase.*" properties in application.properties? You should be able to leave out the Liquibase #Bean and let Boot do it for you.
If you prefer to add you own Liquibase #Bean then take the hint and make sure you define a LiquibaseProperties bean as well (e.g. by declaring #EnableConfigurationProperties(LiquibaseProperties.class)).
