Thank you for your kindly answer.
Finally, I used reflection to update the `ContextManager` and it seemed to
work.
For referenceļ¼
```
ShardingSphereDataSource shardingSphereDataSource =
(ShardingSphereDataSource) dataSource;
Class<ShardingSphereDataSource> shardingSphereDataSourceClass =
ShardingSphereDataSource.class;
Field field =
shardingSphereDataSourceClass.getDeclaredField("contextManager");
field.setAccessible(true);
ContextManager contextManager = (ContextManager)
field.get(shardingSphereDataSource);
HikariDataSource newHikariDataSource = new HikariDataSource();
newHikariDataSource.setDriverClassName(tenantDataSource.getDriverClassName());
// ....
Map<String, DataSource> dataSourceMap =
contextManager.getDataSourceMap(SHARDING_LOGIC_SCHEMA);
dataSourceMap.put(tenantInfo.getTenantName(), newHikariDataSource);
ShardingSphereResource newResource = new
ShardingSphereResource(dataSourceMap);
ShardingSphereDatabase shardingSphereDatabase =
contextManager.getMetaDataContexts().getMetaData().getDatabases().get(SHARDING_LOGIC_SCHEMA);
Class<ShardingSphereDatabase> shardingSphereDatabaseClass =
ShardingSphereDatabase.class;
Field resource = shardingSphereDatabaseClass.getDeclaredField("resource");
resource.setAccessible(true);
resource.set(shardingSphereDatabase, newResource);
field.set(shardingSphereDataSource, contextManager);
```
