在我添加spring-security-oauth2到pom.xml之后：

<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.2.0.RELEASE</version>
</dependency>

我开始得到

Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.context.ApplicationListener : org.springframework.boot.context.logging.ClasspathLoggingApplicationListener
    at org.springframework.boot.SpringApplication.createSpringFactoriesInstances(SpringApplication.java:439)
    at org.springframework.boot.SpringApplication.getSpringFactoriesInstances(SpringApplication.java:418)
    at org.springframework.boot.SpringApplication.getSpringFactoriesInstances(SpringApplication.java:409)
    at org.springframework.boot.SpringApplication.<init>(SpringApplication.java:268)
    at org.springframework.boot.SpringApplication.<init>(SpringApplication.java:247)
    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1245)
    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1233)

运行我的@SpringBootApplication。请注意，我使用的是Spring Boot
2.0.0.M5，我认为这可能是问题的根源（WRT版本）。

这是我正在使用的整个pom.xml：

我怀疑这可能与版本冲突有关-多数关于stackoverflow的答案就是这样-但我无法确定我在这里遇到的实际问题。

Spring Boot 2.0.0.M5 的发行说明说明：

---

Spring Security的 OAuth 2.0支持 功能OAuth项目正在迁移到核心Spring Security。OAuth
2.0客户端支持已被添加，其他功能将在适当时候迁移。

如果您依赖尚未迁移的Spring Security
OAuth功能，则需要org.springframework.security.oauth:spring-security- oauth2手动添加和配置。如果只需要OAuth 2.0客户端支持，则可以使用Spring Boot
2.0提供的自动配置。我们还将继续支持Spring Boot 1.5，以便较旧的应用程序可以继续使用它，直到提供升级路径为止。
