   @bigno-feng Hi,I tested the following code in version 5.3.2, and it can be routed to the main library correctly.
   
   ```java
   public class RwTest {
   
       public static void main(String[] args) throws SQLException {
           //定义数据源
           Map<String, DataSource> map = new HashMap<>();
   
           HikariDataSource dataSource = new HikariDataSource();
           dataSource.setDriverClassName(Driver.class.getName());
           dataSource.setJdbcUrl("jdbc:mysql://localhost:3306/demo_write_ds?serverTimezone=UTC");
           dataSource.setUsername("root");
           dataSource.setPassword("root");
   
           HikariDataSource dataSource1 = new HikariDataSource();
           dataSource1.setDriverClassName(Driver.class.getName());
           dataSource1.setJdbcUrl("jdbc:mysql://localhost:3306/demo_read_ds_0?serverTimezone=UTC");
           dataSource1.setUsername("root");
           dataSource1.setPassword("root");
   
           HikariDataSource dataSource2 = new HikariDataSource();
           dataSource2.setDriverClassName(Driver.class.getName());
           dataSource2.setJdbcUrl("jdbc:mysql://localhost:3306/demo_read_ds_1?serverTimezone=UTC");
           dataSource2.setUsername("root");
           dataSource2.setPassword("root");
   
           map.put("write", dataSource);
           map.put("read_0", dataSource1);
           map.put("read_1", dataSource2);
   
           StaticReadwriteSplittingStrategyConfiguration staticConfiguration
                   = new StaticReadwriteSplittingStrategyConfiguration(
                   "write", Arrays.asList("read_0","read_1"));
   
           ReadwriteSplittingDataSourceRuleConfiguration configuration  =
                   new ReadwriteSplittingDataSourceRuleConfiguration(
                           "abc",staticConfiguration,null,"myBalancer");
   
           Map<String, AlgorithmConfiguration> loadBalancers = new HashMap<>();
   
           Properties prop  = new Properties();
           prop.put("transaction-read-query-strategy","FIXED_PRIMARY");
           loadBalancers.put("myBalancer",new AlgorithmConfiguration("RANDOM",prop));
   
           ReadwriteSplittingRuleConfiguration readwriteSplittingRuleConfiguration  =
                   new ReadwriteSplittingRuleConfiguration(Collections.singleton(configuration),loadBalancers);
           Properties properties  = new Properties();
           properties.put("show-sql",true);
           DataSource abc = ShardingSphereDataSourceFactory.createDataSource(map, Collections.singleton(readwriteSplittingRuleConfiguration), properties);
           Connection connection = abc.getConnection();
   
           connection.setAutoCommit(false);
           for (int i = 0; i < 10; i++) {
               ResultSet resultSet = connection.prepareStatement("select * from t_order").executeQuery();
               while (resultSet.next()){
                   String aLong = resultSet.getString(1);
                   String string = resultSet.getString(2);
                   System.out.println(aLong+"====="+string + "route: " + resultSet.getString(3));
               }
               System.out.println("===============================================");
           }
           connection.commit();
           connection.close();
       }
   }
   ```
