Hibernate Oracle and Character Encoding
提问by Mark
Im having an issue at the moment where my testing environment is not persisting the trademark character "?" in the database. When I enter in the form data, then submit it, I can see that on the server side, the request has the correctly encoded ? character, but then when the call to hibernate's "saveOrUpdate()" method is called, the data in the table shows up as an upside down question mark.
在我的测试环境没有保留商标字符“？”时，我遇到了一个问题。在数据库中。当我输入表单数据然后提交时，我可以看到在服务器端，请求的编码正确？字符，但是当调用 hibernate 的“saveOrUpdate()”方法时，表中的数据显示为倒置的问号。
Im using SqlDeveloper to inspect the table, and I can manually change the character to a ? by pasting directly into the row then committing, and it works.
我使用 SqlDeveloper 检查表，我可以手动将字符更改为 ? 通过直接粘贴到行然后提交，它的工作原理。
So I have made the assumption that hibernates methods of persistence are not working correctly.
所以我假设休眠的持久性方法不能正常工作。
Im at a loss here, really, I just dont know what to try, I have set the:
我在这里不知所措，真的，我只是不知道该尝试什么，我已经设置了：
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">utf-8</property>
properties in the config file, with no luck.
配置文件中的属性，没有运气。
My columns in the tables are NVARCHAR2(400 CHAR) (although they were originally, just VARCHAR2 to start with, but I changed them during the debugging of this issue).
我在表中的列是 NVARCHAR2(400 CHAR)（虽然它们最初只是 VARCHAR2，但我在调试这个问题的过程中改变了它们）。
Any help here is greatly appreciated.
非常感谢这里的任何帮助。
