SpringBoot 應用程序運行失敗

Question

我正在通過教程學習 SpringBoot，為公司的員工數據庫構建一個帶有 API 的示例網站。 當我嘗試運行該應用程序時，我收到以下消息：

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadDatabase' defined in file [/Users/westonjorgensen/Downloads/payroll/target/classes/com/company/payroll/LoadDatabase.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.company.payroll.LoadDatabase$$EnhancerBySpringCGLIB$$6abc07cf]: Constructor threw exception; nested exception is java.lang.Error: Unresolved compilation problems: 
The declared package "payroll" does not match the expected package "com.company.payroll"
The method save(Employee) is undefined for the type EmployeeRepository
The method save(Employee) is undefined for the type EmployeeRepository

整個項目在這里https://github.com/wjorgensen/payroll.git

我正在關注的教程是https://spring.io/guides/tutorials/rest/

關於如何解決問題的任何想法？

Answer 1

包裹有問題。

異常提到<...>/com/company/payroll/LoadDatabase.class但您的項目在src/main/java/com/company/payroll中不包含LoadDatabase.java類。 嘗試將所有類從com.company.payroll包移動到payroll包，如您所遵循的教程中所述。
