## Bug Report **For English only**, other languages will not accept. Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response anymore and we cannot reproduce it on current information, we will **close it**. Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? ``` <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.2.RELEASE</version> </parent> <dependency> <groupId>org.apache.shardingsphere</groupId> <artifactId>shardingsphere-jdbc-core-spring-boot-starter</artifactId> <version>5.0.0-alpha</version> </dependency> ``` ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior ### Actual behavior https://github.com/apache/shardingsphere/blob/5.0.0-alpha/examples/shardingsphere-jdbc-example/sharding-example/sharding-spring-boot-jpa-example/src/main/resources/application-replica-query.properties ``` spring.shardingsphere.datasource.names=primary_ds,replica_ds_0,replica_ds_1 spring.shardingsphere.datasource.common.type=com.zaxxer.hikari.HikariDataSource spring.shardingsphere.datasource.common.driver-class-name=com.mysql.jdbc.Driver spring.shardingsphere.datasource.common.username=root spring.shardingsphere.datasource.common.password= spring.shardingsphere.datasource.primary_ds.jdbc-url=jdbc:mysql://localhost:3306/demo_primary_ds?serverTimezone=UTC&useSSL=false&useUnicode=true&characterEncoding=UTF-8 spring.shardingsphere.datasource.replica_ds_0.jdbc-url=jdbc:mysql://localhost:3306/demo_replica_ds_0?serverTimezone=UTC&useSSL=false&useUnicode=true&characterEncoding=UTF-8 spring.shardingsphere.datasource.replica_ds_1.jdbc-url=jdbc:mysql://localhost:3306/demo_replica_ds_1?serverTimezone=UTC&useSSL=false&useUnicode=true&characterEncoding=UTF-8 spring.shardingsphere.rules.replica-query.load-balancers.round_robin.type=ROUND_ROBIN spring.shardingsphere.rules.replica-query.data-sources.pr_ds.primary-data-source-name=primary_ds spring.shardingsphere.rules.replica-query.data-sources.pr_ds.replica-data-source-names=replica_ds_0,replica_ds_1 spring.shardingsphere.rules.replica-query.data-sources.pr_ds.load-balancer-name=round_robin ``` ``` /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.3.2.RELEASE) 2020-12-10 22:33:12.160 INFO 9469 --- [ main] c.i.d.DistributedShardingApplicationTest : Starting DistributedShardingApplicationTest on MacBook-Pro-2 with PID 9469 (started by admin in /Users/admin/code/myProjects/java/imooc/distributed-sharding) 2020-12-10 22:33:12.161 INFO 9469 --- [ main] c.i.d.DistributedShardingApplicationTest : No active profile set, falling back to default profiles: default 2020-12-10 22:33:12.744 INFO 9469 --- [ main] .s.d.r.c.RepositoryConfigurationDelegate : Bootstrapping Spring Data JPA repositories in DEFERRED mode. 2020-12-10 22:33:12.796 INFO 9469 --- [ main] .s.d.r.c.RepositoryConfigurationDelegate : Finished Spring Data repository scanning in 45ms.
