Spring Boot中ProviderSettings类无法解析的问题求助

我是Spring Boot新手，正在跟随教程搭建OAuth认证服务器。在配置AuthorizationServerConfig.java时，教程中从org.springframework.security.oauth2.server.authorization.config包导入ProviderSettings类，但我的项目中该包下没有这个类。已经尝试查找正确的导入路径并核对依赖，仍未解决问题。请问是缺少依赖还是该类已不再可用？

错误代码示例 #

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

问题原因及解决办法 #

• 核心原因是依赖版本不匹配：你当前使用的Spring Boot版本是3.0.3，对应的Spring Security OAuth2 Authorization Server应该用1.1.x系列，但你配置的是1.0.1。这两个版本里ProviderSettings的包路径不一样：

  • 1.0.x版本：org.springframework.security.oauth2.server.authorization.settings
  • 1.1.x版本：org.springframework.security.oauth2.server.authorization.config（也就是教程里的路径）

• 两种解决方式任选其一：

  1. 升级依赖版本：把spring-security-oauth2-authorization-server的版本改为1.1.2（和Spring Boot 3.0.3兼容的稳定版本），这样就能直接用教程里的导入路径，代码无需改动。
  2. 修改导入路径：保持1.0.1版本不变，把导入语句改成import org.springframework.security.oauth2.server.authorization.settings.ProviderSettings;，代码逻辑不需要调整。
