The Java API rule configuration for broadcast, which allows users to create ShardingSphereDataSource objects directly by writing Java code, is flexible enough to integrate various types of business systems without relying on additional jar packages.
Class：org.apache.shardingsphere.broadcast.config.BroadcastRuleConfiguration
Attributes：
| name | DataType | Description | Default Value |
|---|---|---|---|
| tables (+) | Collection<String> | Broadcast table rules |
The following is an example of the broadcast table Java API configuration:
public final class ShardingDatabasesAndTablesConfigurationPrecise {
@Override
public DataSource getDataSource() throws SQLException {
return ShardingSphereDataSourceFactory.createDataSource(createDataSourceMap(), Arrays.asList(createBroadcastRuleConfiguration()), new Properties());
}
private Map<String, DataSource> createDataSourceMap() {
Map<String, DataSource> result = new HashMap<>();
result.put("demo_ds_0", DataSourceUtil.createDataSource("demo_ds_0"));
result.put("demo_ds_1", DataSourceUtil.createDataSource("demo_ds_1"));
return result;
}
private BroadcastRuleConfiguration createBroadcastRuleConfiguration() {
return new BroadcastRuleConfiguration(Collections.singletonList("t_address"));
}
}
