Java JpaRepository:NoSuchBeanDefinitionException

我使用spring数据jpa。没有弹簧靴

package ru.spb.repository;

public interface CrudUserRepository extends JpaRepository<User, Integer> {
}

xml配置文件：

spring-app.xml

<context:component-scan base-package="ru.spb.service"/>
<context:component-scan base-package="ru.spb.repository"/

问题解决了。 我在my web.xml中contextConfigLocation的参数值中添加了“classpath:spring/spring db.xml”：

 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring/spring-app.xml
        classpath:spring/spring-db.xml
    </param-value>
  </context-param>

上下文配置位置
类路径：spring/spring-app.xml
类路径：spring/spring-db.xml

您是否有机会获得重复的

CrudUserRepository

课程？异常跟踪将包显示为

ru.spb.repository.*user*.CrudUserRepository

，共享的代码不同。可能是不正确的导入？您是否有可能获得重复的
