spring.shardingsphere.datasource.names= # Actual data source name, multiple split by `,`
# <actual-data-source-name> indicate name of data source name
spring.shardingsphere.datasource.<actual-data-source-name>.type= # Full class name of database connection pool
spring.shardingsphere.datasource.<actual-data-source-name>.driver-class-name= # Class name of database driver, ref property of connection pool
spring.shardingsphere.datasource.<actual-data-source-name>.jdbc-url= # Database URL, ref property of connection pool
spring.shardingsphere.datasource.<actual-data-source-name>.username= # Database username, ref property of connection pool
spring.shardingsphere.datasource.<actual-data-source-name>.password= # Database password, ref property of connection pool
spring.shardingsphere.datasource.<actual-data-source-name>.<xxx>= # ... Other properties for data source pool
In this example, the database driver is MySQL, and connection pool is HikariCP, which can be replaced with other database drivers and connection pools. When using ShardingSphere JDBC, the property name of the JDBC pool depends on the definition of the respective JDBC pool, and is not defined by ShardingSphere. For related processing, please refer to the class org.apache.shardingsphere.infra.datasource.pool.creator.DataSourcePoolCreator . For example, with Alibaba Druid 1.2.9, using url instead of jdbc-url in the example below is the expected behavior.
# Configure actual data sources
spring.shardingsphere.datasource.names=ds1,ds2
# Configure the 1st data source
spring.shardingsphere.datasource.ds1.type=com.zaxxer.hikari.HikariDataSource
spring.shardingsphere.datasource.ds1.driver-class-name=com.mysql.jdbc.Driver
spring.shardingsphere.datasource.ds1.jdbc-url=jdbc:mysql://localhost:3306/ds1
spring.shardingsphere.datasource.ds1.username=root
spring.shardingsphere.datasource.ds1.password=
# Configure the 2nd data source
spring.shardingsphere.datasource.ds2.type=com.zaxxer.hikari.HikariDataSource
spring.shardingsphere.datasource.ds2.driver-class-name=com.mysql.jdbc.Driver
spring.shardingsphere.datasource.ds2.jdbc-url=jdbc:mysql://localhost:3306/ds2
spring.shardingsphere.datasource.ds2.username=root
spring.shardingsphere.datasource.ds2.password=
If developer plan to use ShardingSphere-JDBC in Web Server (such as Tomcat) with JNDI data source,
spring.shardingsphere.datasource.${datasourceName}.jndiName can be used as an alternative to series of configuration of data source.
spring.shardingsphere.datasource.names= # Actual data source name, multiple split by `,`
# <actual-data-source-name> indicate name of data source name
spring.shardingsphere.datasource.<actual-data-source-name>.jndi-name= # JNDI of data source
# Configure actual data sources
spring.shardingsphere.datasource.names=ds1,ds2
# Configure the 1st data source
spring.shardingsphere.datasource.ds1.jndi-name=java:comp/env/jdbc/ds1
# Configure the 2nd data source
spring.shardingsphere.datasource.ds2.jndi-name=java:comp/env/jdbc/ds2
