zjcnb opened a new issue, #19432:
URL: https://github.com/apache/shardingsphere/issues/19432

   ### Which version of ShardingSphere did you use?
   
   master
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
   
   ShardingSphere-Proxy
   
   ### Expected behavior
   
   Perceived change
   
   ### Actual behavior
   
   Not perceived
   
   ### Reason analyze (If you can)
   
   ```
    public static MetaDataContexts create(final MetaDataPersistService persistService, final Map<String, DatabaseConfiguration> databaseConfigs,
                                             final InstanceContext instanceContext) throws SQLException {
           Collection<String> databaseNames = instanceContext.getInstance().getMetaData() instanceof JDBCInstanceMetaData
                   ? databaseConfigs.keySet()
                   : persistService.getDatabaseMetaDataService().loadAllDatabaseNames();
           Map<String, DatabaseConfiguration> effectiveDatabaseConfigs = createEffectiveDatabaseConfigurations(databaseNames, databaseConfigs, persistService);
           Collection<RuleConfiguration> globalRuleConfigs = persistService.getGlobalRuleService().load();
           ConfigurationProperties props = new ConfigurationProperties(persistService.getPropsService().load());
           Map<String, ShardingSphereDatabase> databases = ShardingSphereDatabasesFactory.create(effectiveDatabaseConfigs, props, instanceContext);
           ShardingSphereRuleMetaData globalMetaData = new ShardingSphereRuleMetaData(GlobalRulesBuilder.buildRules(globalRuleConfigs, databases, instanceContext));
           return new MetaDataContexts(persistService, new ShardingSphereMetaData(databases, globalMetaData, props), OptimizerContextFactory.create(databases, globalMetaData));
       }
   ```
   
   The database is reassigned, such as :
   
   ```
       public ShardingSphereMetaData(final Map<String, ShardingSphereDatabase> databases, final ShardingSphereRuleMetaData globalRuleMetaData, final ConfigurationProperties props) {
           this.databases = new ConcurrentHashMap<>(databases.size(), 1);
           databases.forEach((key, value) -> this.databases.put(key.toLowerCase(), value));
           this.globalRuleMetaData = globalRuleMetaData;
           this.props = props;
       }
   ```
