Database-driven resource bundle in Spring

basename is a string, so it is not a spring bean, and hence no injection there.

What you can try to do is to subclass ReloadableResourceBundleMessageSource and override some methods there (for example - getMessage(..)). The DAO should be injected in the subclass.

ReloadableResourceBundleMessageSource creates an instance of the class named by the basename property. This instance will not have any of its dependencies injected by Spring. That's why the textDAO field in your Messages object is null.

This Spring issue has the source code for an example JDBC backed MessageSource, as an attachment, which you can use instead of ReloadableResourceBundleMessageSource.
