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

Question

在我将 spring-security-oauth2 添加到我的 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)

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:;

我怀疑这可能与版本冲突有关 - Whosebug 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 Support

Functionality from the Spring Security OAuth project is being migrated to core Spring Security. OAuth 2.0 client support has already been added and additional features will be migrated in due course.

If you depend on Spring Security OAuth features that have not yet been migrated you will need to add org.springframework.security.oauth:spring-security-oauth2 and configure things manually. If you only need OAuth 2.0 client support you can use the auto-configuration provided by Spring Boot 2.0. We’re also continuing to support Spring Boot 1.5 so older applications can continue to use that until an upgrade path is provided.

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 class 路径上。 class 是 spring-context 模块的一部分，是 Spring Framework 4.2 中的新模块。

查看 pom，您没有使用 Boot 的依赖管理（通过导入 spring-boot-dependencies bom 或使用 spring-boot-starter-parent 作为项目的父项。这意味着任何传递的版本依赖关系没有被管理。这是导致问题的原因，因为您的项目正在使用 4.0.9.RELEASE of spring-context 通过 spring-security-oauth2.

传递

我强烈建议您使用 Spring Boot 的依赖管理。如果您不想这样做或由于某些未说明的原因不能这样做，您将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，希望能解决问题。

Answer 3

更新 Maven 项目解决了我的问题..

右键单击您的 Project -> Maven -> Update Project 或快捷方式 Alt+F5

Select Force Update of Snapshots/Releases

Answer 4

我在使用 Gradle+Kotlin 时遇到了这个问题。解决方案是将我的库和主项目中 Spring Boot Gradle 插件的版本设置为相同的值：

plugins {
    id("org.springframework.boot") version "2.2.2.RELEASE"
}
