Spring批處理JdbcPagingItemReader缺少參數

我有一個Spring Batch應用程序，我必須使用Oracle Data Dump根據配置表導出分區。在配置表中，我有如運行導出的日子，要導出的表的名稱等信息。這是我的查詢提供Spring批處理JdbcPagingItemReader缺少參數

private PagingQueryProvider queryProviderStep1() throws Exception { 
     SqlPagingQueryProviderFactoryBean queryProvider = new SqlPagingQueryProviderFactoryBean(); 
     queryProvider.setDataSource(infraConfig.dataSourceLocal()); 
     queryProvider.setDatabaseType("ORACLE"); 
     queryProvider 
       .setSelectClause("SELECT part.partition_name, config.ID_CONFIG_DATA_EXPORT, config.SERVIDOR_ORIGEM, " 
         + "config.SERVIDOR_DESTINO, config.CAMINHO_DESTINO, config.NOME_TABELA, config.TEMPO_RETENCAO_BD, " 
         + "config.TEMPO_RETENCAO_TAPELIBRARY, config.TEMPO_DELAY, config.FREQUENCIA_EXECUCAO "); 
     queryProvider.setFromClause("FROM [email protected]_RAC part " 
       + "INNER JOIN CONFIG_DATA_EXPORT config ON config.NOME_TABELA = part.TABLE_NAME " 
       + "LEFT JOIN CONFIG_DATA_EXPORT_LOG exlog ON config.ID_CONFIG_DATA_EXPORT = exlog.ID_CONFIG_DATA_EXPORT "); 
     queryProvider.setWhereClause(" WHERE exlog.ID_CONFIG_DATA_EXPORT IS NULL"); 
     queryProvider.setSortKey("config.id_config_data_export"); 
     return queryProvider.getObject();

我的問題是，當彈簧產生在查詢末尾的「remainingPagesSql」，它包括「AND（（config.id_config_data_export>？））」。我期待的是，Spring會自動使用SORTKEY作爲參數，但它不是不和給我的錯誤：

org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [SELECT * FROM (SELECT part.partition_name, config.ID_CONFIG_DATA_EXPORT, config.SERVIDOR_ORIGEM, config.SERVIDOR_DESTINO, config.CAMINHO_DESTINO, config.NOME_TABELA, config.TEMPO_RETENCAO_BD, config.TEMPO_RETENCAO_TAPELIBRARY, config.TEMPO_DELAY, config.FREQUENCIA_EXECUCAO FROM [email protected]_RAC part INNER JOIN CONFIG_DATA_EXPORT config ON config.NOME_TABELA = part.TABLE_NAME LEFT JOIN CONFIG_DATA_EXPORT_LOG exlog ON config.ID_CONFIG_DATA_EXPORT = exlog.ID_CONFIG_DATA_EXPORT WHERE exlog.ID_CONFIG_DATA_EXPORT IS NULL ORDER BY config.id_config_data_export ASC) WHERE ROWNUM <= 10 AND ((config.id_config_data_export > ?))]; SQL state [99999]; error code [17041]; Missing IN or OUT parameter at index:: 1; nested exception is java.sql.SQLException: Missing IN or OUT parameter at index:: 1

我試圖映射參數，但我沒有或不知道如何使用這個參數，因爲它基於PAGE_SIZE，所以在每次執行查詢時，值都會改變。

先編輯
我已經更新了SORTKEY爲「id_config_data_export」，沒有「配置」。但錯誤仍然發生。

SQL是否在SQL客戶端中運行？ –

它運行時沒有'（（config.id_config_data_export>？））'，但它與我得到ORA-00904字符串：無效的標識符，但我不明白爲什麼，因爲這是我的主鍵，它的工作。 –

我沒有看到它在堆棧跟蹤中......你是否從工廠中獲得正確類型的'SqlQueryProvider'？ –

終於讓它工作了！我不是直接用Java編寫查詢，而是用查詢創建了一個視圖，它工作正常。我仍然不知道爲什麼它不起作用，但這是解決方法。這是現在的queryProvider：

private PagingQueryProvider queryProviderStep1() throws Exception { 
     SqlPagingQueryProviderFactoryBean queryProvider = new SqlPagingQueryProviderFactoryBean(); 
     queryProvider.setDataSource(infraConfig.dataSourceLocal()); 
     queryProvider.setDatabaseType("ORACLE"); 
     queryProvider.setSelectClause("SELECT * "); 
     queryProvider.setFromClause("FROM VW_CONFIG_EXPORT_PART_CDRONE "); 
     queryProvider.setSortKey("id_config_data_export"); 
     return queryProvider.getObject();
