Answer 1

From your log , you should have a Class called AccessConfirmationController .It has an internal property whose type is ClientAuthenticationCache, right?

The error says you do not define any beans whose type is ClientAuthenticationCache , so theAccessConfirmationController bean cannot be created too.

You could use the Spring ‘s component scanning feature to automatically detect and instantiate the ClientAuthenticationCache .

To enable the component scanning feature , add <context:component-scan base-package="some.package"> in the applicationContext.xml .Any classes in the specified base-package and its sub-packages that are annotated with @Component subtypes such as @Controller,@Repository, @Service can automatically discovered and instantiated by Spring.
