The project already use [redissson ](https://github.com/redisson/redisson/)framework ``` <redisson:client id="redissonClient" netty-threads="20" threads="20" name="redissonClinet"> <redisson:cluster-servers idle-connection-timeout="${redisson.idleConnectionTime}" connect-timeout="${redisson.connectTimeout}" timeout="${redisson.timeout}" retry-attempts="${redisson.retryAttempts}" retry-interval="${redisson.retryInterval}" scan-interval="${redisson.scanInterval}" client-name="cleitName"> <redisson:node-address value="${redisson.hostAndPort1}" /> <redisson:node-address value="${redisson.hostAndPort2}" /> <redisson:node-address value="${redisson.hostAndPort3}" /> <redisson:node-address value="${redisson.hostAndPort4}" /> <redisson:node-address value="${redisson.hostAndPort5}" /> <redisson:node-address value="${redisson.hostAndPort6}" /> </redisson:cluster-servers> </redisson:client> ``` and when I use **shardingsphere-jdbc-5.0.0-alpha** version in project，in the proccess of application startup, [ShardingSphereAlgorithmBeanRegistry ](https://github.com/apache/shardingsphere/blob/c05b58b1610b18503f436a61db1d24dba72c7e33/shardingsphere-jdbc/shardingsphere-jdbc-spring/shardingsphere-jdbc-spring-infra/shardingsphere-jdbc-spring-namespace-infra/src/main/java/org/apache/shardingsphere/spring/namespace/registry/ShardingSphereAlgorithmBeanRegistry.java#L48) class iterate all beanDefinitions by **beanDefinitionNames**，but there was a beanDefination‘s '**beanClassName**' attribute was null，and then when it **equals** with _**algorithmFactoryBeanClassName**_, it causes **NPE**   @menghaoranss ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
