URL: https://github.com/apache/shardingsphere/issues/16751

   i want use the hash_mod sharding-algorithm, and have configure the sharding-count , but when i start the project
   it throw the exception as the below, why?
   
   
   [org/apache/shardingsphere/sharding/spring/boot/ShardingRuleSpringBootConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.shardingsphere.infra.config.RuleConfiguration]: Factory method 'shardingRuleConfiguration' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hash_mod_user': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Sharding count cannot be null.
   
   
   and my config like this:
   
   sharding-algorithms:
             hash_mod_user:
               type: HASH_MOD
               props:
                 sharding-count: '2'

   i have solved the problem， 'hash_mod_user' do not works ，because  it must replace the '_' to '-',  as  'hash-mod-user'

   Hi @luckleemon 
   What is the version of ShardingSphere?  
   Please provide some more information, like sharding table rule.  I suspect this problem is caused by not using auto table.
