I have a spring boot application and I want to add liquibase configuration change log for it.
I have created a LiquibaseConfig class for configuring liquibase:
@Configuration
public class LiquibaseConfiguration {
@Value("${com.foo.bar.liquibase.changelog}")
private String changelog;
@Autowired
MysqlDataSource dataSource;
@Bean
public SpringLiquibase liquibase() {
SpringLiquibase liquibase = new SpringLiquibase();
liquibase.setDataSource(dataSource);
liquibase.setChangeLog(changelog);
return liquibase;
}
}
and I have configured the datasource information in properties file:
spring.datasource.url=jdbc:mysql://localhost:3306/dms
spring.datasource.username=root
spring.datasource.password=test
spring.datasource.testWhileIdle = true
spring.jpa.show-sql = true
#liquibase
com.foo.bar.liquibase.changelog=classpath:/db/changelog/db.changelog.xml
when I run my application I receive this error:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'liquibaseConfiguration': Unsatisfied dependency expressed through field 'dataSource': No qualifying bean of type [com.mysql.jdbc.jdbc2.optional.MysqlDataSource] found for dependency [com.mysql.jdbc.jdbc2.optional.MysqlDataSource]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.mysql.jdbc.jdbc2.optional.MysqlDataSource] found for dependency [com.mysql.jdbc.jdbc2.optional.MysqlDataSource]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
Now I understood that this means the application cannot autowire the MysqlDataSource dataSource;
but I need to pass the data source to liquibase bean. How can I do that?
Here's a simple step to integrate liquibase in spring boot
Add liquibase dependency
runtime "org.liquibase:liquibase-core"
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
<scope>runtime</scope>
</dependency>
Add liquibase changelog file path in application.yml
liquibase:
enabled: true #this is optional as enabled by default
change-log: classpath:/liquibase/db-changelog.xml
Notice property liquibase.change-log.
I'm referring path as /liquibase/db-changelog.xml.
so you should have a file name db-changelog.xml
inside src/main/resources/liquibase/
Add your changesets on the file and when Spring-Boot application is started (spring-boot:run
) your changeset will be loaded.
This will use default dataSource
that your app uses.
For Spring Boot 2.0 as @veben pointed out in comment use
spring:
liquibase:
change-log: #path
