SpringBoot无法注入JpaRepository接口 (找不到指定Bean)

2020-07-15 14:09:28.821 WARN 11732 — [ restartedMain] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘genController’: Unsatisfied dependency expressed through field ‘iGenTableService’; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘genTableServiceImpl’: Unsatisfied dependency expressed through field ‘genTableRepository’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.bella.dao.GenTableRepository’ available: expected at least 1 bean which qualifies as autowire candidate.

两个Bean的定义都没问题 , 但是 GenTableServiceImpl 却无法在Spring容器中找到 GenTableRepository 这个Bean 。 注意 : 我们使用的是JpaRepository (spring-data-jpa)的功能 , 可能是项目框架中没有定义 JpaRepository 扫描包的位置 或 定义的位置和我们Class的位置不一致导致我们的 Bean 无法的注入到 Spring 容器中。
