Spring Boot集成OAuth库遇类无法解析问题求助

在Spring Boot中集成OAuth库时，出现以下类无法解析的报错：

ProtectedResourceDetails cannot be resolved to a type
OAuthConsumerSupport cannot be resolved to a type
BaseProtectedResourceDetails cannot be resolved to a type

当前pom.xml依赖配置如下：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.5.2.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-test</artifactId>
    <scope>test</scope>
</dependency>

需要引入正确依赖以使用以下类：

OAuthConsumerSupport oAuthConsumerSupport = new CoreOAuthConsumerSupport();
ProtectedResourceDetails is24ClientKeyDetails = createIs24ClientKeyDetails();
BaseProtectedResourceDetails protectedResourceDetails = new BaseProtectedResourceDetails();

类无法解析的核心原因是混用了新旧两套Spring OAuth体系，依赖配置存在冲突：

1. 明确类归属：ProtectedResourceDetails、OAuthConsumerSupport、BaseProtectedResourceDetails都属于旧版Spring Security OAuth项目（org.springframework.security.oauth组），和Spring Boot官方提供的新版OAuth2 Starter（spring-boot-starter-oauth2-client/resource-server）不属于同一体系，二者不兼容。

2. 调整依赖配置：

   • 移除冲突的新版OAuth Starter依赖：spring-boot-starter-oauth2-client和spring-boot-starter-oauth2-resource-server。
   • 建议通过Spring Boot的依赖管理自动控制spring-security-oauth2版本，避免手动指定版本号引发的版本不匹配问题。

调整后的pom.xml依赖示例：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<!-- 仅保留旧版Spring Security OAuth2依赖 -->
<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-test</artifactId>
    <scope>test</scope>
</dependency>

3. 额外提示：旧版Spring Security OAuth项目已停止维护，若为新项目建议迁移至Spring官方推荐的新版OAuth2体系，不过这意味着需要重构代码，用RegisteredClient、OAuth2AuthorizedClient等新版API替代旧类。
