the class Sql112Application method main.

public static void main(String[] args) throws Exception {
    // deSer sql context

    configMap.forEach((key, value) -> Configurations.setConfig(tEnv, key, value));
    // step 2: add catalog
    List<Catalog> catalogs = sqlContext.getCatalogs();
    Catalogs.registerCatalogsToTableEnv(tEnv, catalogs);
    // step 3: create temporary system function
    List<Function> functions = sqlContext.getFunctions();
