Question

在调用API时从休眠查询下面获取异常。

dao类方法：

public List<ErmChangeLog> fetchChangeLog(JsonInput jsonInput) throws SQLException {
    Session session = this.sessionFactory.openSession();    
    List<ErmChangeLog> objectList = null;
    Long instanceKey = 0L;
    try {
        instanceKey = jsonInput.getSystematic_Risk_ID();
        logger.debug("Connection creation process is completed.");
        Query query = session.createQuery(CommonConstants.fetch_ChangeLog);
        logger.info("query   : " + CommonConstants.fetch_ChangeLog);
        query.setParameter("instanceKey", instanceKey);
        logger.info("instanceKey : " + instanceKey);
        objectList = query.list();

    } catch (Exception e) {
        logger.debug("Failed to fetch Change Log");
        e.printStackTrace();
        throw e;
    }
    session.close();
    return objectList;

}

query：字符串fetch_ChangeLog =“来自ErmChangeLog p，其中p.instanceKey =：instanceKey”;

例外：

看起来您的参数与查询期望的数据类型不匹配。您可以尝试使用Integer代替Long吗？
