## Bug Report Under JPA use repository to save entity to DB I defined my own ComplexKeysShardingAlgorithm use two columns (dealer_id & company_code) to shard table But these two columns could not be null, when one of them is null Then got java.lang.IllegalArgumentException: Sharding value must implements Comparable. ### Which version of ShardingSphere did you use? implementation 'org.apache.shardingsphere:sharding-jdbc-core:4.1.1' ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior JPA repo save successfully ### Actual behavior got java.lang.IllegalArgumentException: Sharding value must implements Comparable. ### Reason analyze (If you can) In org.apache.shardingsphere.sharding.route.engine.condition.engine.InsertClauseShardingConditionEngine#getRouteValue ```java Preconditions.checkArgument(result instanceof Comparable, "Sharding value must implements Comparable."); ``` this code will check sharding value is instanceof Comparable and throw above Exception ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. as above ### Example codes for reproduce this issue (such as a github link). as above ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
