问题描述

此问题已解决.请在下面查看检查后的答案.

我将DAO重新配置为更方便的方式(通过使用JpaRepository)，而不是手动完成所有样板代码.但是现在每次我启动Spring Application时，都会出现以下错误:

I reconfigured my DAOs to a more convenient way (by using JpaRepository) instead of doing all that boilerplate code manually. But now everytime I start the Spring Application it gives me the following error:

申请无法开始

说明:

DAO.UserDAOService中的字段userRepository需要找不到类型为'DAO.UserRepository'的bean.

Field userRepository in DAO.UserDAOService required a bean of type 'DAO.UserRepository' that could not be found.

注入点具有以下注释: -@ org.springframework.beans.factory.annotation.Autowired(required = true)

The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true)

动作:

考虑在您的配置中定义类型为'DAO.UserRepository'的bean.

Consider defining a bean of type 'DAO.UserRepository' in your configuration.

以退出代码1完成的过程

Process finished with exit code 1
