java - 在我的 Spring 应用程序中配置 hibernate 的问题

Question

我在 Spring 应用程序上配置 hibernate ，并在 servlet-context 文件上出现以下错误。

我把 xml 文件弄乱了什么？

错误如下:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 38 in XML document from ServletContext resource [/WEB-INF/servlet-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 38; columnNumber: 109; cvc-complex-type.2.4.a: Invalid content was found starting with element 'bean'. One of '{"http://www.springframework.org/schema/beans":import, "http://www.springframework.org/schema/beans":alias, "http://www.springframework.org/schema/beans":bean, WC[##other:"http://www.springframework.org/schema/beans"], "http://www.springframework.org/schema/beans":beans}' is expected.

我的 Servlet-context.xml

Answer 1

您开始使用命名空间前缀

<beans:bean...

和

<beans:property...

但是你停下来了

<bean...

和

<property...

为什么？任何属于 beans 命名空间的元素都需要以 beans 为前缀。

或者，将 bean 设置为 default namespace这样您就不必为属于它的所有元素添加前缀。
