org.springframework.beans.factory.BeanCreationException：创建bean时出错

Question

我正在尝试使用Hibernate配置Spring Framework 2.5.6.SEC01 + JPA，但是当春天尝试创建一个Bean，我的xml和下面的错误堆栈跟踪时，我得到一个异常：

注意：

在我的项目中我需要使用Spring ver 2.5.6而不是Spring ver 3.x.x

请帮帮我......

解 XML文件内容可能以@Sotirios Delimanolis答案作为BOM前缀 CTRL +再次删除并编写手册：）

非常感谢:)。

Answer 1

您的XML文件内容可能以BOM为前缀。 sax解析器期望正常<开始XML文档，但是找到字节顺序标记。

您必须将其删除。可以找到执行此操作的示例here。

Answer 2

我从3.2.0.RELEASE更改了Spring jdbc jar版本 至 3.0.4.RELEASE 它已经开始工作了
