Configure Rule

Using ZooKeeper as config center and registry center for example.

governance:
  name: governance_ds
  registryCenter:
      type: Zookeeper
      serverLists: localhost:2181
  overwrite: true

// Create GovernanceShardingSphereDataSource
DataSource dataSource = YamlGovernanceShardingSphereDataSourceFactory.createDataSource(yamlFile);

Use GovernanceShardingSphereDataSource

The GovernanceShardingSphereDataSource created by YamlGovernanceShardingSphereDataSourceFactory implements the standard JDBC DataSource interface. Developer can choose to use native JDBC or ORM frameworks such as JPA or MyBatis through the DataSource.

Take native JDBC usage as an example:

DataSource dataSource = YamlGovernanceShardingSphereDataSourceFactory.createDataSource(yamlFile);
String sql = "SELECT i.* FROM t_order o JOIN t_order_item i ON o.order_id=i.order_id WHERE o.user_id=? AND o.order_id=?";
try (
        Connection conn = dataSource.getConnection();
        PreparedStatement ps = conn.prepareStatement(sql)) {
    ps.setInt(1, 10);
    ps.setInt(2, 1000);
    try (ResultSet rs = preparedStatement.executeQuery()) {
        while(rs.next()) {
            // ...
        }
    }
}
