The Spring Data CrudRepository has various methods that return multiple instances of the entity managed by the repository. It does so by using Iterable and not List, as one might expect. In many cases, that is of no consequence, since you typically want to iterate over the result anyway. However, you might occasionally prefer a List. In these cases, Iterable is annoying.

I will write more about why that choice was made in the first place and how you can deal with it as long as you are on Spring Data 2.x. However, let me get the good news out first:

In Spring Security 5.7.0-M2 we deprecated the WebSecurityConfigurerAdapter, as we encourage users to move towards a component-based security configuration.

To assist with the transition to this new style of configuration, we have compiled a list of common use-cases and the suggested alternatives going forward.

In the examples below we follow best practice by using the Spring Security lambda DSL and the method HttpSecurity#authorizeHttpRequests to define our authorization rules. If you are new to the lambda DSL you can read about it in this blog post. If you would like to learn more about why we choose to use HttpSecurity#authorizeHttpRequests you can check out the reference documentation…

On behalf of the community, I’m pleased to announce the release of Spring Security 5.5.5 (release notes) and Spring Security 5.6.2 (release notes). These releases deliver bug fixes along with some minor improvements. Users are encouraged to update to the latest patch release.
