Use Spring Namespace

• Import Maven Dependency
• Configure Rule
• Use ShardingSphereDataSource in Spring

Import Maven Dependency

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

Configure Rule

Note: The example database connection pool is HikariCP, which can be replaced with other mainstream database connection pools according to business scenarios.

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;
