添加spring-security-oauth2后无法实例化接口org.springframework.context.ApplicationListener

问题描述 投票：4回答：3

我将spring-security-oauth2添加到我的pom.xml后：

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

我开始得到了

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)

在运行我的@SpringBootApplication之后。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（w.r.t.版本）。

这是我正在使用的整个pom.xml：;

我怀疑这可能与冲突的版本有关 - stackoverflow上的大多数答案都是这样 - 但我无法弄清楚我在这里遇到的实际问题。

Spring Boot 2.0.0.M5状态的release notes：

OAuth 2.0支持 Spring Security OAuth项目的功能正在迁移到核心Spring Security。已添加OAuth 2.0客户端支持，并将在适当时候迁移其他功能。 如果您依赖尚未迁移的Spring Security OAuth功能，则需要手动添加org.springframework.security.oauth:spring-security-oauth2并进行配置。如果您只需要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，因此较旧的应用程序可以继续使用它，直到提供升级路径。

修复了示例pom的问题后，我现在可以看到失败的完整堆栈跟踪：

问题的根本原因是org.springframework.context.event.GenericApplicationListener不在类路径上。该类是spring-context模块的一部分，是Spring Framework 4.2中的新增功能。

看看pom，你没有使用Boot的依赖管理（通过导入spring-boot-dependencies bom或者使用spring-boot-starter-parent作为项目的父级。这意味着任何传递依赖的版本都没有被管理。这就引起了这里的问题您的项目通过spring-context传递使用4.0.9.RELEASE的spring-security-oauth2。

我强烈建议您使用Spring Boot的依赖关系管理。如果您不想这样做或因某些未说明的原因而无法执行此操作，则必须手动确保所有传递依赖项都具有受支持的版本。

尝试使用以下配置，希望它能解决问题。
