中方法setUserService的参数0需要找不到类型的bean

Question

我经历了这个问题，找不到发生了什么....试图@ComponentScan，试图命名我的服务，似乎没有一个工作。

Description:

Parameter 0 of method setUserService in com.ipayso.services.security.UserDetailsServiceImpl required a bean of type 'com.ipayso.services.UserService' that could not be found.


Action:

Consider defining a bean of type 'com.ipayso.services.UserService' in your configuration.

Answer 1

如果您在运行junit测试时收到这个错误，那么您可能需要为该对象添加模拟

@MockBean ClassError class Error；在具有@SpringBootConfiguration注释的类中

Answer 2

您正在此处查找< code > @ Qualifier(value = " UserService ")的< code>UserService:

@Autowired
@Qualifier(value = "userService")
public void setUserService(UserService userService) {
    this.userService = userService;
}

但是你没有它，因为你的UserServiceImpl注释为@Service而没有提供它的id。

要为您的UserServiceImpl设置id，您需要使用@Service（“userService”）。但是，如果您有一个UserService实现，只需从setter中删除@Qualifier（value=“UserService”），因为它是冗余的。

在我看来，这不是唯一一个你必须删除@Qualifier的地方。

@Qualifier如果您有许多相同类型的bean，则需要注释来选择精确的bean。如果你有一个，你不需要使用它。
