## 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 ``` # 配置真实数据源 spring.shardingsphere.datasource.names=ds0,ds1 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= 123456 spring.shardingsphere.datasource.ds0.jdbc-url=jdbc:mysql://localhost:3306/ds0?serverTimezone=UTC&useSSL=false spring.shardingsphere.datasource.ds1.jdbc-url=jdbc:mysql://localhost:3306/ds1?serverTimezone=UTC&useSSL=false # 配置 t_order 表规则 spring.shardingsphere.rules.sharding.tables.t_order.actual-data-nodes=ds$->{0..1}.t_order$->{0..1} # 配置分库策略 spring.shardingsphere.rules.sharding.tables.t_order.database-strategy.standard.sharding-column=user_id spring.shardingsphere.rules.sharding.tables.t_order.database-strategy.standard.sharding-algorithm-name=database_inline # 配置分表策略 spring.shardingsphere.rules.sharding.tables.t_order.table-strategy.standard.sharding-column=order_id spring.shardingsphere.rules.sharding.tables.t_order.table-strategy.standard.sharding-algorithm-name=table_inline # 配置 分片算法 spring.shardingsphere.rules.sharding.sharding-algorithms.database_inline.type=INLINE spring.shardingsphere.rules.sharding.sharding-algorithms.database_inline.props.algorithm-expression=ds_${user_id % 2} spring.shardingsphere.rules.sharding.sharding-algorithms.table_inline.type=INLINE spring.shardingsphere.rules.sharding.sharding-algorithms.table_inline.props.algorithm-expression=t_order_${order_id % 2} ``` ### Expected behavior ### Actual behavior ``` Configuration property name 'spring.shardingsphere.rules.sharding.sharding-algorithms.database_inline.props' is not valid: Invalid characters: '_' Reason: Canonical names should be kebab-case ('-' separated), lowercase alpha-numeric characters and must start with a letter ``` fix it. ``` # 配置真实数据源 spring.shardingsphere.datasource.names=ds0,ds1 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= 123456 spring.shardingsphere.datasource.ds0.jdbc-url=jdbc:mysql://localhost:3306/ds0?serverTimezone=UTC&useSSL=false spring.shardingsphere.datasource.ds1.jdbc-url=jdbc:mysql://localhost:3306/ds1?serverTimezone=UTC&useSSL=false # 配置 t_order 表规则 spring.shardingsphere.rules.sharding.tables.t_order.actual-data-nodes=ds$->{0..1}.t_order$->{0..1} # 配置分库策略 spring.shardingsphere.rules.sharding.tables.t_order.database-strategy.standard.sharding-column=user_id spring.shardingsphere.rules.sharding.tables.t_order.database-strategy.standard.sharding-algorithm-name=databaseinline # 配置分表策略 spring.shardingsphere.rules.sharding.tables.t_order.table-strategy.standard.sharding-column=order_id spring.shardingsphere.rules.sharding.tables.t_order.table-strategy.standard.sharding-algorithm-name=tableinline # 配置 分片算法 spring.shardingsphere.rules.sharding.sharding-algorithms.databaseinline.type=INLINE spring.shardingsphere.rules.sharding.sharding-algorithms.databaseinline.props.algorithm-expression=ds_${user_id % 2} spring.shardingsphere.rules.sharding.sharding-algorithms.tableinline.type=INLINE spring.shardingsphere.rules.sharding.sharding-algorithms.tableinline.props.algorithm-expression=t_order_${order_id % 2} ``` Application run failed ``` 2020-11-27 18:28:08.224 ERROR 46307 --- [ main] o.s.boot.SpringApplication : Application run failed java.lang.reflect.InvocationTargetException: null at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_251] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_251] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_251] ``` ### Reason analyze (If you can) ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ### Example codes for reproduce this issue (such as a github link). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
