URL: https://github.com/apache/shardingsphere/issues/37572
Hi everyone, I have a question regarding the definition of an own
CLASS_BASED sharing algorithm in a Spring Boot application.
I need to define a programatic sharding rule based on the customer ID and I
want to store these configuration in a database table that will be filled based
on business rules. As my application is a SpringBoot application I want to be
able to inject the JPA repository into my sharding algorithm to retrieve the
config from database.
I realize that using the standard configuration, ShardingSphere builds the
class instance using the default constructor, so can't inject anything and the
algorithm don't belongs to Spring context.
```
shardingAlgorithms:
customer-to-shard:
type: CLASS_BASED
props:
strategy: STANDARD
algorithmClassName:
com.jpenalver10.dbsharding.TenantShardingAlgorithm
```
Is there any recommended/official way to do this?
Thank you so much.
