[I] Properties `strategy` can not be null when uses class based sharding strategy. [shardingsphere]
YXxy1002 opened a new issue, #34011:
URL: https://github.com/apache/shardingsphere/issues/34011
## Question
why can't i read props
### Which version of ShardingSphere did you use?
`
<dependency>
<groupId>org.apache.shardingsphere</groupId>
<artifactId>shardingsphere-jdbc-core-spring-boot-starter</artifactId>
<version>5.2.1</version>
</dependency>
`
### YAML
`
shardingsphere:
rules:
sharding:
sharding-algorithms:
uidshardingalgorithm:
type: CLASS_BASED
props:
strategy: standard
algorithmClassName: com.task.config.UidShardingAlgorithm
tables:
t_task_recommend:
actual-data-nodes: dw.t_task_recommend
table-strategy:
standard:
sharding-column: Duid
sharding-algorithm-name: uidshardingalgorithm
`
### Actual behavior
`Caused by: java.lang.NullPointerException: Properties `strategy` can not be null when uses class based sharding strategy.
