休眠 4.3.11 与 c3p0 0.9.5.2 setCharacterStream 导致 AbstractMethodError答案

【问题标题】：Hibernate 4.3.11 with c3p0 0.9.5.2 setCharacterStream causes AbstractMethodError休眠 4.3.11 与 c3p0 0.9.5.2 setCharacterStream 导致 AbstractMethodError
【发布时间】：2017-04-07 13:05:55
【问题描述】：

我知道这个问题已经在各种问题中得到了处理，我认为HERE 中的答案似乎是合乎逻辑的解决方案，但对我来说它无济于事。仅保存或更新某个实体时会发生错误。与所有其他人一起，它的工作方式很奇怪 \oO/

这是我的堆栈跟踪：

当我加载应用程序时，c3p0 日志是：

这是我的 pom.xml sn-p（我不得不从 hibernate-c3p0 中排除 c3p0，因为它正在加载与 JDBC4 驱动程序不兼容的旧版本）

我现在不知道在哪里寻找根本原因...... 这可能与 LanguageText 实体类中的一些 JPA 配置有关吗？不过里面没什么好看的……

感谢您对此的任何提示。

【问题讨论】：

我刚刚意识到我的项目似乎没有使用 JDBC4 。它打印此日志 INFO [main] 07.04.17 15:19:11.978 org.hibernate.engine.jdbc.internal.LobCreatorBuilder@useContextualLobCreation: HHH000423: Disabling contextual LOB creation as JDBC driver reported JDBC version [3] less than 4 。但是 Spring 4.3.11 应该使用 JDBC4 ......现在我更加困惑了
它与 Spring 或 C3P0 无关...您使用的驱动程序是 JDBC3 驱动程序而不是 JDBC4 驱动程序（在 the website 中也明确说明）。此外，您应该删除 hibernate-annotations 依赖项，因为它应该由核心包含（或管理）。
@M.Deinum 感谢您的回复。由于我正在处理的应用程序非常老旧，并且将其接管以重构为更新的技术，我有很多工作要做。有没有办法从 JTDS 到某事。使用 JDBC4 没有任何问题？我尝试了 microsoft 的原始 sqljdbc 驱动程序，但随后一半的 HQL 语句给了我类似 conversion from nvarchar to clob not possible 的错误。有什么好的方法吗？为什么没有使用 JDBC4 的 JTDS 继任者？
为什么没有 JTDS 的 JDBC4 版本你必须问项目作者我无法回答。您在切换到其他驱动程序时是否指定了正确的方言？
@M.Deinum 我真的没想到我的愚蠢问题会得到答案 ;-) 我指定了 SQLServerDialect 并尝试使用 SQLServer2008

标签： spring hibernate c3p0

【解决方案1】：

所以我终于找到了我的问题所在，并且像往常一样它坐在椅子和屏幕之间。通过添加真正的 JDBC4 驱动程序解决了 setCharacterStream 方法问题。我选择了微软自己的那个。我不会提到这个选择带来的大量问题，但它解决了标题中提到的问题。

对于那些关心的人：我的转换问题真的很愚蠢。我仔细查看了实体类，并在字符串字段上找到了 @Lob 注释。嗯...删除它，解决了转换问题。我不知道为什么这适用于 JTDS（我认为 JTDS 比 MS 驱动程序更聪明，并且在这种情况下有一些内部自动转换......）。
