Question

我正在使用Spring Boot 2.1.1和Java 8开发微服务应用程序。此数据库中使用的数据库是AWS DynamoDB。运行我的应用程序时出现以下错误：-

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userProfileJpaRepository': Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

完整的错误日志：-
