我采用java代码用客户端向服务端发出jdbc查询请求但是不能返回数据。同样的语句用命令行确可以实现查询es请问是我哪里配置错误了吗？（已经同步过元数据）
代码如下：
`public static void main(String[] args) throws ClassNotFoundException, SQLException {

Class.forName("com.qihoo.qsql.client.Driver"); //注入Drvier

Properties properties = new Properties();
properties.setProperty("runner","jdbc");
String url = "jdbc:quicksql:url=http://10.121.8.4:5888";
Connection connection = DriverManager.getConnection(url,properties);
Statement pS = connection.createStatement();
String sql = "SELECT * FROM product";
ResultSet rs =  pS.executeQuery(sql);
int j=0;
while (rs.next()) {
	for (int i = 1; i <= rs.getMetaData().getColumnCount(); i++) {
		System.out.println(rs.getMetaData().getColumnName(i)
				+ ":" + rs.getObject(i)+"|");
	}
	j++;
	System.out.println("行数"+j);
}
rs.close();
pS.close();

}`

错误如下：
20/04/10 18:08:14 INFO DynamicSqlRunner: The SQL that is ready to execute is: SELECT count(*) FROM product 20/04/10 18:08:14 INFO DynamicSqlRunner: Read schema from manual schema, schema or path is: inline: { "version": "1.0", "defaultSchema": "QSql", "schemas": [{ "type": "custom", "name": "ecommerce", "factory": "com.qihoo.qsql.org.apache.calcite.adapter.elasticsearch.ElasticsearchCustomSchemaFactory", "operand": { "coordinates": "{'10.121.8.5': 9200}", "userConfig": "{'bulk.flush.max.actions': 10, 'bulk.flush.max.size.mb': 1,'esUser':'','esPass':''}", "index": "ecommerce" }, "tables": [ { "name": "product", "factory": "com.qihoo.qsql.org.apache.calcite.adapter.elasticsearch.ElasticsearchTableFactory", "operand": { "dbName": "ecommerce", "tableName": "product", "esNodes": "10.121.8.5", "esPort": "9200", "esUser": "", "esPass": "", "esIndex": "ecommerce/product", "esScrollNum": "1" }, "columns": [ {"name": "desc:string"}, {"name": "name:string"}, {"name": "price:bigint"}, {"name": "producer:string"}, {"name": "tags:string"} ] } ] } ] } java.lang.RuntimeException: java.sql.SQLException: Error while executing SQL "SELECT COUNT(*) FROM ecommerce.productASproduct`": Error while compiling generated Java code:
