Use Spring Boot Starter

Import Maven Dependency

<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>shardingsphere-jdbc-core-spring-boot-starter</artifactId>
    <version>${shardingsphere.version}</version>
</dependency>

Configure Rule

# Configure actual data sources
spring.shardingsphere.datasource.names=ds0,ds1

# Configure the first data source
spring.shardingsphere.datasource.ds0.type=org.apache.commons.dbcp2.BasicDataSource
spring.shardingsphere.datasource.ds0.driver-class-name=com.mysql.jdbc.Driver
spring.shardingsphere.datasource.ds0.url=jdbc:mysql://localhost:3306/ds0
spring.shardingsphere.datasource.ds0.username=root
spring.shardingsphere.datasource.ds0.password=

# Configure the second data source
spring.shardingsphere.datasource.ds1.type=org.apache.commons.dbcp2.BasicDataSource
spring.shardingsphere.datasource.ds1.driver-class-name=com.mysql.jdbc.Driver
spring.shardingsphere.datasource.ds1.url=jdbc:mysql://localhost:3306/ds1
spring.shardingsphere.datasource.ds1.username=root
spring.shardingsphere.datasource.ds1.password=

# Configure t_order table rule
spring.shardingsphere.rules.sharding.tables.t_order.actual-data-nodes=ds$->{0..1}.t_order$->{0..1}

# Configure database sharding strategy
spring.shardingsphere.rules.sharding.tables.t_order.database-strategy.standard.sharding-column=user_id
spring.shardingsphere.rules.sharding.tables.t_order.database-strategy.standard.sharding-algorithm-name=database_inline

# Configure table sharding strategy
spring.shardingsphere.rules.sharding.tables.t_order.table-strategy.standard.sharding-column=order_id
spring.shardingsphere.rules.sharding.tables.t_order.table-strategy.standard.sharding-algorithm-name=table_inline

# Omit t_order_item table rule configuration ...
# ...

# Configure sharding algorithm
spring.shardingsphere.rules.sharding.sharding-algorithms.database_inline.type=INLINE
spring.shardingsphere.rules.sharding.sharding-algorithms.database_inline.props.algorithm-expression=ds_${user_id % 2}
spring.shardingsphere.rules.sharding.sharding-algorithms.table_inline.type=INLINE
spring.shardingsphere.rules.sharding.sharding-algorithms.table_inline.props.algorithm-expression=t_order_${order_id % 2}

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 datasource. For example:

# Configure actual data sources
spring.shardingsphere.datasource.names=ds0,ds1

# Configure the first data source
spring.shardingsphere.datasource.ds0.jndi-name=java:comp/env/jdbc/ds0
# Configure the second data source
spring.shardingsphere.datasource.ds1.jndi-name=java:comp/env/jdbc/ds1

# Omit rule configurations ...
# ...

Use ShardingSphereDataSource in Spring

ShardingSphereDataSource can be used directly by injection; or configure ShardingSphereDataSource in ORM frameworks such as JPA or MyBatis.

@Resource
private DataSource dataSource;
