Question

在运行项目时，出现以下错误：

***************************
APPLICATION FAILED TO START
***************************

Description:

Field userDetailsService in org.o7planning.sbshoppingcart.config.WebSecurityConfig required a bean of type 'org.o7planning.sbshoppingcart.service.UserDetailsServiceImpl' that could not be found.


Action:

Consider defining a bean of type 'org.o7planning.sbshoppingcart.service.UserDetailsServiceImpl' in your configuration.

我搜索了同样的错误，并提示添加@ComponentScan({"com.o7planning"})。因此，我在主类中添加了@ComponentScan，这个bean错误消失了：

当我像这样添加此属性时：

@SpringBootApplication
@ComponentScan({"com.o7planning"})
@EnableAutoConfiguration(exclude = { //  
        DataSourceAutoConfiguration.class, //
        DataSourceTransactionManagerAutoConfiguration.class, //
        HibernateJpaAutoConfiguration.class })

public class SbHibernateShoppingCart1Application {


    public static void main(String[] args) {
        SpringApplication.run(SbHibernateShoppingCart1Application.class, args);
    }
//i have full code down

}

但是当我运行项目时，我的spring安全配置消失了，并显示了spring的默认登录形式。

显示默认登录屏幕，因为这需要由我在春季提供的登录页面覆盖：

所以，仅通过添加@ComponentScan，我的spring安全性就无法正常工作了。什么问题？

所以，我的代码是：
