Liquibase with Spring Boot and multiple schemas, how to specify execution order

After some scratching of heads and digging into the source code, it turns out to be extremely simple.

SpringLiquibase implements InitializingBean and executes the Liquibase update within the InitializingBean.afterPropertiesSet() method.

Spring calls this method on each bean, one by one, after finishing initializing each one.

So to force a particular order, you need to force the order in which the beans are defined in the Spring context. And the easiest way to do this is with the @DependsOn annotation.

So we put in place something like:

@Bean
public SpringLiquibase liquibaseA(
    @Qualifier("dataSourceA") DataSource dataSource,
    @Qualifier("liquibasePropertiesA") LiquibaseProperties liquibaseProperties
) {
    return instantiateSpringLiquibase(dataSource, liquibaseProperties); 
}

@Bean
@DependsOn("liquibaseA")
public SpringLiquibase liquibaseB(
    @Qualifier("dataSourceB") DataSource dataSource,
    @Qualifier("liquibasePropertiesB") LiquibaseProperties liquibaseProperties
) {
    return instantiateSpringLiquibase(dataSource, liquibaseProperties); 
}

private SpringLiquibase instantiateSpringLiquibase(DataSource dataSource, LiquibaseProperties liquibaseProperties) {
    // set the datasource from dataSource and everything else from liquibaseProperties
}
