Answer 1

命名空间的顺序无关紧要。确保spring-data-jpa工件位于类路径中，并仔细检查模式版本。没有spring-jpa-2.0这样的东西。它应该介于1.0和1.3之间。使用Spring，您通常也可以省略版本并默认获取最新模式。

Answer 2

问题是bean架构的定义。

更改xmlns="http://www.springframework.org/schema/beans"

xmlns:beans="http://www.springframework.org/schema/beans"

Answer 3

您可以添加bean;

xmlns:jpa="http://www.springframework.org/schema/data/jpa"
