将 spring boot 从 2.1.0 升级到 2.2.2.RELEASE ，现在启动时出现异常

Question

我将SpringBoot版本2.1.0升级到2.2.2.RELEASE

java：openjdk11 弹簧启动：v2.2.0.RELEASE springCloudVersion : Hoxton.RC1

错误：

应用程序启动失败

说明：

试图调用一个不存在的方法。尝试是从以下位置进行的：

springfox.documentation.spring.web.plugins.DocumentationPluginsManager.createContextBuilder(DocumentationPluginsManager.java:152)

以下方法不存在：

 org.springframework.plugin.core.PluginRegistry.getPluginFor(Ljava/lang> /Object;Lorg/springframework/plugin/core/Plugin;)Lorg/springframework/plugin/core/Plugin;

该方法的类 org.springframework.plugin.core.PluginRegistry 可从以下位置获得：

jar:file:/home/cuelogic.local/kanisha.modi/.gradle/caches/modules-2/files-2.1/org.springframework.plugin/spring-plugin-core/2.0.0.RELEASE/95fc8c13037630f4aba9c51141f535becec00fe6/spring-plugin-core-2.0.0.RELEASE.jar!/org/springframework/plugin/core/PluginRegistry.class

它是从以下位置加载的：

file:/home/cuelogic.local/kanisha.modi/.gradle/caches/modules-2/files-2.1/org.springframework.plugin/spring-plugin-core/2.0.0.RELEASE/95fc8c13037630f4aba9c51141f535becec00fe6/spring-plugin-core-2.0.0.RELEASE.jar

行动：

更正应用程序的类路径，使其包含一个兼容的 org.springframework.plugin.core.PluginRegistry 版本

由

引起的错误

如何解决这个问题？请帮助我，将不胜感激。 我想将我的应用升级到springboot v2.2.2。所以需要这个版本的解决方案。

Answer 1

更新您的 springfox-swagger 版本。我用 boot 2.2.2 运行 springfox 2.9.2

编辑 98.01.2020：

你不知何故在你的类路径中得到了 spring-plugin-core-2.2.0.RELEASE。 SpringFox 需要 1.2.0 版本，Spring Boot 2.2.2 本身并没有拉入这个。你能运行 gradle dependencies --configuration runtimeClasspath 并检查哪个依赖拉入这个版本吗？
