使用Spring Hibernate的问题 [英] Problems using Spring Hibernate

问题描述

我一直使用Spring JDBC取得了巨大的成功，但是我在这个项目中遇到了很多麻烦。我会在这里发布代码链接（这只是一个小而愚蠢的项目，以测试我是否可以启动并运行，以便将来可以使用Hibernate）：

xml-file： http://codepaste.net/uw19zc

main-file： http://codepaste.net/iks1cp

我收到了很多错误，比如

  [致命错误] bean2.out.xml：1 ：1：文件过早结束。 
 13：21：39,471 FATAL [main] Main  -  getAssociatedStylesheets失败
  

t创建了a.out.xml文件。

解决方案

这个错误是由于对xml文件的解析不正确。
使用Eclipse验证它会给出错误：

lockquote
cvc-complex-type.2.3：元素'beans'不能包含字符因为该类型的内容类型仅为元素。

似乎在一个或多个那些< bean> 声明。你是否从其他地方复制过这些文字？

删除< bean> 定义之间的所有空格和换行符，并将其放回到您的编辑器中。

更新
复制&将记事本++粘贴到您提供的代码语言中，然后将字符集设置为UTF-8将这些字符显示为空行： xA0 。这是& nbsp; 的标准Unicode转换。这可能是造成这个问题的原因。

这证实了我的好处：

 <？xml version =1.0encoding =UTF-8？> 
< beans xmlns =http://www.springframework.org/schema/beans
 xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xsi：schemaLocation =http://www.springframework.org/schema/beans

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):

xml-file: http://codepaste.net/uw19zc

main-file: http://codepaste.net/iks1cp

I get tons of errors such as

[Fatal Error] bean2.out.xml:1:1: Premature end of file.
13:21:39,471 FATAL [main] Main  - getAssociatedStylesheets failed

and I haven't created a.out.xml file.

解决方案

This error is due to incorrect parsing of the xml file. Using Eclipse to validate it gives the error:

cvc-complex-type.2.3: Element 'beans' cannot have character [children], because the type's content type is 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?

Remove all spaces and newline characters between <bean> definitions and put them back with your editor.

UPDATE Copying & 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.

This validates ok for me:

<?xml version="1.0" encoding="UTF-8"?>
