Spring boot REST API application doesn't see OAuth2 libraries

Question

I want to secure my REST API with authentication using OAuth2, but on beginning of my journey i faced some problems like "Cannot resolve symbol 'AuthorizationServerConfigurerAdapter'" didn't find any solution on the internet so i asking you. I simply cannot import it and with i write something like import org.springframework.security.oauth2.client.OAuth2ClientContext; it says that in cannot resolve oauth2.

Answer 1

我手动下载了库（ http://central.maven.org/maven2/org/springframework/security/oauth/spring-security-oauth2/2.3.0.RELEASE/ ），并将其安装在“项目设置”->“库”中”

Answer 2

Group id contains an error. It must be oauth without 2. The final version looks like this:

<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.3.6.RELEASE</version>
</dependency>
