@MrXionGe
Hi， you can config this ：
```
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.ds_0.jdbc-url=jdbc:mysql://192.169.2.29:3306/demo_ds_0?serverTimezone=UTC&useSSL=false
spring.shardingsphere.datasource.ds_1.jdbc-url=jdbc:mysql://192.169.2.29:3306/demo_ds_1?serverTimezone=UTC&useSSL=false
```
why:
if you not config datasource common , in springboot 2.4 May be NullpointExcepiton
you also see #8299

@yu199195
Thank you so much!
And. Can version 5.0.0-alpha be used in a production environment?
I hope the documents and examples can be more complete about 5.x.
