最佳答案
您的应用程序上下文缺少JPA架构参考。
此行为您提供问题的位置:
来自类路径资源的XML文档中的第14行
[applicationContext.xml]无效;嵌套异常为
org.xml.sax.SAXParseException; lineNumber:14; columnNumber:43;艾尔
prefijo“ jpa” para el elemento“ jpa:repositories” noestáenlazado。
解决方案是正确引用jpa模式:
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
...
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.8.xsd
...
>
请注意您的
context.xml
如何缺少xmlns:jpa
