Spring Boot项目集成Sharding-jdbc, 配置的是单库分表，正常添加了pom、配置文件。其中sharding-sphere使用了当前最新的版本： 4.1.1

spring:
  shardingsphere:
    datasource:
      names: master
      master:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://xxx:3306/xxx
        username: xx
        password: xx
    sharding:

          key-generator:
            column: id

          actual-data-nodes: master.st_$->{0..3}
          table-strategy:
            inline:
              sharding-column: st_id
              algorithm-expression: st_$->{st_id % 4}

启动后报数据源相关错误
Failed to configure a DataSource: ‘url’ attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class

Sharding-jdbc url attribute is not specified

解决

参考网上一般的解决方案 升级POM版本 没有效果，看Issues（ https://github.com/apache/shardingsphere/issues/3831 ）里有提到排除相关boot-starter。

尝试将原先使用的pom
