Thymeleaf 3.0 implements the Spring 5.0 view infrastructure for WebMVC
and the new WebFlux framework. This commit adds auto-configuration for
the WebFlux support.
In that process, the configuration property for `spring.thymeleaf` has
been changed to add `spring.thymeleaf.servlet` and
`spring.thymeleaf.reactive` for MVC/WebFlux specific properties.
Now that the `spring-boot-starter-thymeleaf` does not only support
Spring MVC, the transitive dependency on `spring-boot-starter-web` is
removed from it.
Fixes gh-8124
We can't easily solve the problem by not allowing Spring Security to
eagerly instantiate everything, but we can be defensive about data.sql
and make sure it is executed even if the listener isn't yet registered.
Fixes gh-1386
