APPLICATIONFAILEDTOSTART以下方法不存在：org.springframework.plugin.core.PluginRegistry.of(org.springframewor-有解無憂

我新創建了一個spring boot專案并添加了swagger依賴項，現在當我試圖運行我的應用程式時，我得到了以下錯誤，我已經嘗試了這個解決方案鏈接1和這個來自stackoverflow的鏈接2，但它并沒有解決我的問題。請幫助我解決這個問題。

這是錯誤的描述：

。

***************************
應用程式未能啟動
***************************

描述。

有人試圖呼叫一個不存在的方法。該嘗試是從以下位置進行的。

    org.springframework.hateoas.server.core.DelegatingLinkRelationProvider.<init>/span>（DelegatingLinkRelationProvider.java:36

以下方法并不存在。

    'org.springframework.plugin.core.PluginRegistry org.springframework.plugin.core.PluginRegistry.of(org.springframework.plugin.core.Plugin[])'

該方法的類，org.springframework.plugin.core.PluginRegistry，可以從以下位置獲得。

    jar:file:/C:/Users/john/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar! /org/springframework/plugin/core/PluginRegistry.class

類的層次結構從以下位置加載。

    org.springframework.plugin.core.PluginRegistry: file:/C:/Users/john/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar


行動。

糾正你的應用程式的classpath，使其包含一個單一的、兼容的org.springframework.plugin.core.PluginRegistry的版本

uj5u.com熱心網友回復：

看來你有不兼容的版本。請嘗試以下方法（將springfox-swagger2和springfox-swagger-ui依賴關系替換為springfox-boot-starter）：
