我对命名空间做错了什么？

我认为问题在于您使用spring-data-commons-core版本1.1和spring-data-jpa版本1.2。对齐这些库的版本。

从我看到的一个项目中查看pom.xml文件。

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.2.0.RELEASE</version>
</dependency>

它使用spring-data-commons-core-1.4.0.RELEASE.jar

如果您将spring-data-jpa的包装切换为pom，则应下载必要的依赖项，然后将其切换回jar。
