Couchbase 5.0 with Spring-boot XML configuration - spring-boot

Question

How to Spring-boot XML configuration with couchbase 5.0?
Full story: Recently, upgraded couchbase server from 4.0.0-4051 to 5.0.0 build 3519 (both are community versions).
Couchbase 4.0 was a bucket based authorization and couchbase 5.0 became Role-Based Access Control (RBAC). (user can have an access to particular buckets).
I have a Spring-boot application which all configs are through XML beans. It works perfectly with couchbase 4.0 but when I change to couchbase 5.0 (note all credentials are CORRECT) I get following error:
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'userRepo'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'couchbaseRepositoryOperationsMapping' available

My dependencies are:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.5.RELEASE</version>
</parent>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-couchbase</artifactId>
</dependency>
I can overcome this issue through manual couchbase client configuration (I already made a sample and tested.) through this code (as explained here https://blog.couchbase.com/new-sdk-authentication/):
Cluster cluster = CouchbaseCluster.create();
cluster.authenticate("username", "password");
Bucket bucket = cluster.openBucket("bucket-name");
(If source required here it is https://github.com/mashhur/twitter_blockchain)
Anyway XML option would be very appreciated!

Better RBAC support with Spring Boot and Spring Data is on the way. It's in the current milestones and should be in a release soon! See DATACOUCH-322 targeted to Kay SR6 and Lovelace M2.
Also, note you can make 5.0 behave like earlier releases by simply creating a user whose name is the same as the bucket.
