oracle ojdbc7问题-升级到ojdbc7驱动程序后，camel-sql组件无法执行查询

Question

将ojdbc驱动程序升级到ojdbc7后，camel-sql组件在使用命名参数执行查询时开始产生问题。

提供了在执行期间失败的简单SQL查询。并非所有查询都失败，但只有少数查询失败。

SELECT some_id 
  FROM app_schema.app_store_table 
 WHERE store_id = :#storeId 
   AND source = :#source;

在数据库端，已验证用户名具有使用app_schema的对象的权限，并且还尝试创建PUBLIC同义词，但没有运气。

根据我的理解，它在尝试获取SqlProducer.java→process()→execute()→ps.getParameterMetaData()中的参数计数时失败，>

jdbcTemplate.execute(statementCreator, new PreparedStatementCallback<Map<?, ?>>() {
    public Map<?, ?> doInPreparedStatement(PreparedStatement ps) throws SQLException {
       int expected = parametersCount > 0 ? parametersCount : ps.getParameterMetaData().getParameterCount();
       ...
进一步的调试从ojdbc7驱动程序中发现以下错误。它确认ojdbc7驱动程序未能正确解析查询。在下面的示例中，在执行之前，将.和schema_name之间的“ table_name”（[DOT]）替换为ojdbc驱动程序。

可以使用以下命令轻松复制。

-- example for .[DOT] getting replaced between schema_name and table_name. Refer Parameter SQL.
C:\Users\xxxxxx\Desktop\ojdbc\oracle>java -cp ojdbc7_g-12.1.0.2.jar oracle.jdbc.driver.OracleParameterMetaDataParser "*SELECT some_id FROM app_schema.app_store_table WHERE store_id = ? and source = ?*"
SQL:SELECT some_id FROM app_schema.app_store_table WHERE store_id = :1  and source = :2
  SqlKind:SELECT, Parameter Count=2
  Parameter SQL: ***SELECT store_id, source FROM app_schemaapp_store_table***
-- example for invalid parsing of the query. Refer Parameter SQL. 
C:\Users\vm\ojdbc\oracle>java -cp ojdbc7_g-12.1.0.2.jar oracle.jdbc.driver.OracleParameterMetaDataParser "*SELECT f_some_id FROM app_store_table WHERE f_store_id = ? and f_source = ?*"
SQL:SELECT f_some_id FROM app_store_table WHERE f_store_id = :1  and f_source = :2
  SqlKind:SELECT, Parameter Count=2
  Parameter SQL: ***SELECT f, f FROM app_store_table***
例外：

@ Venkat。我正在使用骆驼和sql组件，并且发生了这种情况，这里的小问题是，我无法显示查询，原因是映射器显示了奇怪的数据，我的意思是我一直在锁定某种方式来捣乱查询，而这是输出。
