I have spring boot application which use 2 databases. I defined 2 configurations providing specified datasources. I want to have that datasources managed separately by liquibase. I defined 2 separated changelog files.
The problem is that I can't define 2 separate beans for liquibase.
Here are my config classes:
...
public class CCSConfiguration {
...
@Bean
@ConfigurationProperties("ccs.liquibase")
public LiquibaseProperties ccsLiquibaseProperties() {
return new LiquibaseProperties();
}
@Bean
public SpringLiquibase ccsLiquibase(LiquibaseProperties liquibaseProperties) {
...
}
...
}
...
public class CCAConfiguration {
...
@ConfigurationProperties("cca.liquibase")
public LiquibaseProperties ccaLiquibaseProperties() {
return new LiquibaseProperties();
}
@Bean
public SpringLiquibase ccaLiquibase(LiquibaseProperties liquibaseProperties) {
...
}
...
}
And properties:
cca:
liquibase:
change-log: classpath:config/liquibase/cca/master.xml
ccs:
liquibase:
change-log: classpath:config/liquibase/ccs/master.xml
With this config i get following error while running appliction:

Description:
A component required a bean named 'liquibase' that could not be found.
Action:
Consider defining a bean named 'liquibase' in your configuration.
So, is it possible to define multiple liquibase beans for different datasources?
there are two options:
you define a bean named liquibase to let spring-boot integrated process to update your schema on you first DS. You have to handle the second one by hand
you disable liquibase automatic update at startup with
and define your way DS and liquibase beans to update your two databases
