未找到 ProviderSettings 类，它显示无法解析符号 ProviderSettings

Question

我是 Spring Boot 空间的新手。我正在按照教程学习创建 OAuth 身份验证服务器。

在配置

AuthorizationServerConfig.java

时，讲师从包“org.springframework.security.oauth2.server.authrization.config”导入“ProviderSettings”类

但是，我没有从该特定包中获得该类。

我是否缺少任何依赖项？还是现在没有课程？

参考文献1：错误点。无法解析符号 ProviderSettings

@Bean
    public ProviderSettings providerSettings(){
        return ProviderSettings.builder()
                .issuer("http://auth-server:9000")
                .build();
    }

I tried to find the correct import for the required class i.e. 'ProviderSettings'
Cross checked dependencies.

Answer 1

你不会相信我，但我几分钟前刚刚解决了这个问题。看起来该指南使用的是过时版本

spring-security-oauth2-authorization-server

他们改名了

ProviderSettings to AuthorizationServerSettings

https://github.com/spring-projects/spring-authorization-server/issues/864

https://github.com/spring-projects/spring-authorization-server/issues/681

https://github.com/spring-projects/spring-authorization-server/issues/986

他们应该将这些更改添加到文档中或使其更加清晰（IMO）

Answer 2

我猜你指的是这个人：https://youtu.be/zvR-Oif_nxg?t=32043 .

其实他不太清楚自己在做什么，添加样板代码。

无论如何，您可以使用 Spring 的参考指南，其中显示了授权服务器的工作示例： https://docs.spring.io/spring-authorization-server/reference/getting-started.html#defining-required-components

@Bean
public AuthorizationServerSettings authorizationServerSettings() {
    return AuthorizationServerSettings
            .builder()
            .issuer("http://auth-server:9000")
            .build();
}
