Caused by: java.lang.IllegalArgumentException: CONTAINING (1): [IsContaining, Containing, Contains]is not supported for redis query derivation - Redis

Question

I\'m developing Spring Boot + Redis example. In this example, I\'ve developed some custom methods which pull details based on RoleName. For the below method

Answer 1

On Redis with Spring Boot you just have some queries for finder that are supported like Is, Equals, combine with And, Or , you can take a look on Table 9:

UPDATED

You can create a query following this documentation link as reference

https://docs.spring.io/spring-data/redis/docs/2.1.2.RELEASE/reference/html/#query-by-example

Answer 2

Ok lets start from "How Redis Work"

Redis work on Hashes for ID which helps in faster location of record. @Indexed is also hashed and stored for faster pin-pointing the record

So By Default for MiddleName the "contain" query will not work as Hash for "Test" string will not be contained in Hash for String "TestUser".

But ExampleMatcher is here to the rescue.

Source: https://docs.spring.io/spring-data/redis/docs/2.1.2.RELEASE/reference/html/#query-by-example

Solution for RoleName search on Role Object is relatively simple: Use this query

userRepository.findByRoleRoleName("ADMIN") (Basically remove the underscore)

And good news is that it can be combined with the above ExampleMatcher.

Let's discuss if you have doubt.
