Problems using Spring Hibernate
提问by why_vincent
I've been using Spring JDBC with great success but I am having alot of trouble with this project. I'll post the code links here(it's just a small and silly project to test if I can get it up and running so that I can use Hibernate in the future):
我一直在使用 Spring JDBC 并取得了巨大的成功，但我在这个项目中遇到了很多麻烦。我将在这里发布代码链接（这只是一个小而愚蠢的项目，用于测试我是否可以启动并运行它以便我将来可以使用 Hibernate）：

xml 文件：http: //codepaste.net/uw19zc

I get tons of errors such as
我收到大量错误，例如
[Fatal Error] bean2.out.xml:1:1: Premature end of file.

and I haven't created a.out.xml file.
我还没有创建 a.out.xml 文件。

This error is due to incorrect parsing of the xml file. Using Eclipse to validate it gives the error:
此错误是由于对 xml 文件的错误解析造成的。使用 Eclipse 来验证它给出了错误：
cvc-complex-type.2.3: Element 'beans' cannot have character [children], because the type's content type is element-only.
cvc-complex-type.2.3：元素 'beans' 不能有字符 [children]，因为该类型的内容类型是 element-only。
There appears to be some strange character in between one or many of those <bean>declarations. Have you copied this text from somewhere else?
在这些<bean>声明中的一个或多个之间似乎有一些奇怪的字符。您是否从其他地方复制了此文本？
Remove all spaces and newline characters between <bean>definitions and put them back with your editor.
删除<bean>定义之间的所有空格和换行符，并将它们放回您的编辑器中。
UPDATECopying & pasting into notepad++ the text in the codepaste you provided, and setting the charset to UTF-8 showed these characters in the blank lines: xA0. This is the standard Unicode translation for . This is likely to be the cause of this problem.
更新将您提供的代码粘贴中的文本复制并粘贴到记事本 ++ 中，并将字符集设置为 UTF-8 会在空行中显示这些字符：xA0. 这是 . 这很可能是导致此问题的原因。
This validates ok for me:
这对我来说没问题：

If you are in linux, use cat -v file-name.xmlto detect special "invisible" characters like 'M-BM-' in your xml file
如果您使用的是 linux，请用于cat -v file-name.xml检测 xml 文件中的特殊“不可见”字符，例如“M-BM-”
