Use Native Data Source

Configuration Item Explanation

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

Example

In this example, the database driver is MySQL, and connection pool is HikariCP, which can be replaced with other database drivers and connection pools.

# 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=

Use JNDI Data Source

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.

Configuration Item Explanation

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

Example

# 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
