需要一个“com.supriya.banking.repository”类型的bean。找不到AccountRepository

应用程序启动失败

说明:

com.supriya.banking.service中的字段帐户存储库。AccountService需要类型为“com.supriya.banking.repository”的bean。找不到AccountRepository。

注射点有以下注释: -@org.springframework.beans.factory.commentation。自动连线(必填=真)

行动:

考虑定义一个“com.supriya.banking.repository”类型的bean。配置中的AccountRepository。

为什么它要求创建bean,它不应该自己创建吗?
