Background

Any data source object configured as Spring bean can be used with the Spring namespace of ShardingSphere-JDBC Data Planning.

The database driver in the example is MySQL and the connection pool is HikariCP, both of which can be replaced by other database drivers and connection pools. When using ShardingSphere JDBC, the property names of the JDBC pools depend on the definition of JDBC pools themselves respectively, rather than being rigidly defined by ShardingSphere. For relevant processing, you can see reference class org.apache.shardingsphere.infra.datasource.pool.creator.DataSourcePoolCreator. As for Alibaba Druid 1.2.9, using url instead of jdbcUrl as in the following example is the expected behavior.
