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

Description:

Field tokenEndpoint in com.nebula.cloud.auth.controller.AuthController required a bean of type 'org.springframework.security.oauth2.provider.endpoint.TokenEndpoint' that could not be found.

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

Action:

Consider defining a bean of type 'org.springframework.security.oauth2.provider.endpoint.TokenEndpoint' in your configuration.

Disconnected from the target VM, address: '127.0.0.1:56396', transport: 'socket'

Process finished with exit code 1

自定义实现认证授权服务，报以上异常错误

异常内容报错很明显是TokenEndpoint这个对象并没有实例化，注入失败

但是为什么会是实例化失败呢

spring boot在启动时候回自动注入相关依赖，实例化TokenEndpoint，然而事实上并没有，经过分析是未在配置类上添加@EnableAuthorizationServer导致

EnableAuthorizationServer这个注解上会导入

AuthorizationServerEndpointsConfiguration

如果为配置@EnableAuthorizationServer这个注解，就不会实例化TokenEndpoint对象
