Shall we change the property name to apollo.check.database-name?
And is it better to use the ConditionalOnProperty mechanism? e.g.

@ConditionalOnProperty(value = {"apollo.check.database-name"}, havingValue = "true", matchIfMissing = true)

OK, I will revise it in this way.

I want to add logic to check the database name before creating the data source.
If use the @ConditionalOnProperty to deal with it, there will be a problem. There is a dependency in admin service,
adminServiceAuthenticationFilter -> bizConfig -> bizDBPropertySource -> serverConfigRepository -> serverConfig -> entityManager -> dataSourceScriptDatabaseInitializer -> dataSource, when the servlet is initialized, the filter will be initialized first,this will cause the data source to initialize, so unable to add name check before data source initialization. it seems meaningless if the name check is added after the data source is initialized，or is it the wrong way I handled it?
