liubao616 opened a new issue #2932: Cannot obtained Data from multiple data sources when integrating MyBatis with HitManager URL: https://github.com/apache/incubator-shardingsphere/issues/2932 **Hey !** Our company uses multi-tenant mode, each tenant corresponds to a database. Now we need to get the data of two tenants at the same time, using HitManager strong routing mode. __Here is a simulated custom HintSharing Algorithm algorithm,The code is as follows:__ ` public class MyHintShardingAlgorithm implements HintShardingAlgorithm<String>{ public Collection<String> doSharding(Collection<String> availableTargetNames, HintShardingValue<String> shardingValue) { Collection<String> result=new ArrayList<String>(); //more dataSources result.add("MD_COMMON_OA"); result.add("MD_XXZX_OA"); return result; } } ` __Data can be obtained using java. sql API，The code is as follows:__ ` public void test2() throws SQLException { HintManager hintManager=HintManager.getInstance(); hintManager.setDatabaseShardingValue("MD_XXZX_OA:MD_COMMON_OA"); String sql="SELECT * from test_table"; try (Connection connection = dataSource.getConnection(); PreparedStatement preparedStatement = connection.prepareStatement(sql)) { preparedStatement.setString(1, "MD_XXZX_OA"); try (ResultSet resultSet = preparedStatement.executeQuery()) { int i=0; while (resultSet.next()) { System.out.print("application_code:" + resultSet.getObject(1) + ", "); } } } hintManager.close(); }` __But you can not get data using MyBatis, The code is as follows:__ ` public void test3() throws SQLException { SqlSession session= sqlSessionFactory.openSession(); HintManager hintManager=HintManager.getInstance(); hintManager.setDatabaseShardingValue("MD_XXZX_OA:MD_COMMON_OA"); List<Map<String, Object>> datas=session.selectList("getStartFlowListBySysType", "MD_XXZX_OA"); session.commit(); System.out.println(datas.size()); hintManager.close(); }` __The version I use is：4.0.0-RC3-SNAPSHOT__
