Spring Batch JdbcPagingItemReader缺少参数

我有一个Spring Batch应用程序，我必须使用Oracle Data Dump导出基于配置表的分区。在配置表中，我有运行导出的天数，要导出的表的名称等信息。 这是我的查询提供程序

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 user_tab_partitions@CDRONE_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();

我遇到的问题是Spring生成剩余的页面＆＃39;它包括＆＃39; AND（（config.id_config_data_export＆gt;？））＆＃39;在查询结束时。我期待Spring会自动使用sortKey作为参数，但它没有并且给我错误：

我已尝试映射参数，但我不知道如何使用此参数，因为它基于PAGE_SIZE，所以每次查询执行后，值会改变。

第一次编辑
我已将sortKey更新为＆＃34; id_config_data_export＆＃34;，没有＆＃34; config。＆＃34;。但错误仍然存​​在。

终于成功了！我没有直接用Java编写查询，而是使用查询创建了一个视图，并且它工作正常。我仍然不知道它为什么不起作用，但这是解决方法。 这是queryProvider现在：

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();
