sorry, I can't reappear it when I use sharding jdbc 5.2.1 in a demo project, so I think this is a compatibility issue with other frameworks，such as mybatis-plus, shiro and so on. So I later use sharding jdbc 5.1.2, other issues arise at this time, it occrus NullPointerException. Trace the source code back. It occrus in this line in 'ClassBasedShardingAlgorithm'  I think it doesn't Inject my algorithm class normally. My yaml like this: ` spring: shardingsphere: datasource: names: ds0 ds0: type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.cj.jdbc.Driver url: "jdbc:mysql://172.18.100.87:3306/eeyes_energy?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&serverTimezone=GMT" username: root password: hgny initial-size: 10 max-active: 100 min-idle: 10 max-wait: 60000 pool-prepared-statements: true max-pool-prepared-statement-per-connection-size: 20 time-between-eviction-runs-millis: 60000 min-evictable-idle-time-millis: 300000 test-while-idle: true test-on-borrow: false test-on-return: false stat-view-servlet: enabled: true url-pattern: /druid/* #login-username: admin #login-password: admin filter: stat: log-slow-sql: true slow-sql-millis: 1000 merge-sql: false wall: config: multi-statement-allow: true rules: sharding: tables: data_energy_15min: actual-data-nodes: ds0.data_energy_15min_$->{2020..2030}${(1..12).collect{t->t.toString().padLeft(2,'0')}} table-strategy: standard: sharding-column: stat_date_time sharding-algorithm-name: dateTime sharding-algorithms: dateTime: type: CLASS_BASED props: strategy: STANDARD algorithmClassName: com.hgny.energy.module.data.sharding.StatTimeShardingAlgorithm props: sql-show: true `  Can you spot any problems, please. -- This is an automated message from the Apache Git Service.
