【问题描述】：

我正在将使用 Oauth 的云应用从 spring-boot 1.5 升级到 2.2.4。它在本地工作，但在部署到 PCF 时失败。

以下是依赖项。我的第一个怀疑是版本不兼容到目前为止还无法追踪与这些的冲突。谁能提供方向？

org.springframework.cloud:spring-cloud-starter-oauth2:jar:2.2.0.RELEASE
org.springframework.security.oauth:spring-security-oauth2:jar:2.4.0.RELEASE
org.springframework.boot:spring-boot-starter-oauth2-resource-server:jar:2.2.4.RELEASE
org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure:jar:2.1.2.RELEASE
org.springframework.security:spring-security-openid:jar:5.2.1.RELEASE
io.pivotal.spring.cloud:spring-cloud-services-starter-config-client:jar:2.2.0.RELEASE

Method userInfoRestTemplateFactory in org.springframework.boot.autoconfigure.security.oauth2.resource.ResourceServerTokenServicesConfiguration required a single bean, but 4 were found:

这是由于该库的副本被拉入。删除副本后问题就消失了。

<dependency>
  <groupId>org.springframework.security</groupId>
  <artifactId>spring-security-oauth2-resource-server</artifactId>
