Spring 5.0.0.M3調用ApplicationEventListener時出錯：沒有ServletContext set - 在上下文初始化期間遇到異常

今天我決定從最新的Spring 4.3官方發佈版本切換到5.0.0.M3版本，這要感謝他支持junit多線程內置它的Flux gestion絕對聽起來很有趣。Spring 5.0.0.M3調用ApplicationEventListener時出錯：沒有ServletContext set - 在上下文初始化期間遇到異常

花了整整一天玩我的pom.xml試圖找出爲什麼它不起作用，我終於設法使它工作，至少我認爲，mvn測試命令運行良好，並輸出一個建築成功我所有的百次單元測試。 Altough應用程序不啓動，這讓我這個奇怪的錯誤：

我發現了一些非常類似的錯誤，到這裏並通過谷歌搜索，但事情是它總是從與另一個無法用非常明確的消息啓動的bean發生錯誤。在我的情況下，它說servlet上下文沒有設置，我可以理解會有問題，但我不明白爲什麼它沒有設置？任何人都有線索？感謝您的未來幫助！

請問你能分享一個樣本，我們可以運行重現問題？ –

@ stephane-nicoll我可以嘗試在專用的環境中重現此操作，並將發送完成後，感謝您的答案！ –

@ stephane-nicoll我試圖在一個新的項目中使用相同的配置和相同的pom.xml重現這一點，除了我刪除了所有的bean和我的項目的核心，這樣只有配置被留在這裏，並且工作順利......我可能在另一個項目的IDE中有一些問題，讓我檢查所有這些 –

雖然試圖分享一個非工作的例子，但我發現這一個按預期工作。因此，我試圖評論我的配置類的一些部分，並設法進行春季啓動。其實這個問題是以下幾點：其擴展WebMvcConfigurationSupport類我的春天配置類包含

public void addInterceptors(InterceptorRegistry registry);

我用這個方法來添加一個customHandlerInterceptor爲一些自定義的原因。問題是這個攔截器是一個在另一個conf類中聲明的bean，並且我使用@Autowired註解來獲取它在這個實際的類中。由於我忽略的原因，這個過去與以前的Spring版本一起工作，但現在它不再了......我設法通過在這個類中聲明這個bean給我所有這些問題來獲得這個bean，而不是從@Autowired註釋。引導現在運行良好，除了在每個請求我收到了404錯誤：例如

2017-08-30 16:43:03.379 WARN 18584 --- [nio-8082-exec-4] o.s.web.servlet.PageNotFound : No mapping found for HTTP request with URI [/v1/admin/validate] in DispatcherServlet with name 'dispatcherServlet'

編輯 -

映射實際工作，但在Spring 4.3它曾經考慮「/v1「之前，這個參數是在application.properties中給出的，我沒有把它考慮進去。看起來swagger文檔插件在新的spring版本中還不被支持，因爲整個文檔只是不加載，而是在重定向時發送404。除此之外，我的處理程序現在沒有正確註冊，但我想這是因爲我已經做了錯誤的最新修改，所以我需要先解決這個問題。

EDIT 2 -

我讀的地方，在Spring 5，你必須更換「擴展WebMvcConfigurerAdapter」，因爲第一個被棄用「擴展WebMvcConfigurerSupport」級，然而這並沒有爲工作我和我不得不實現WebMvcConfigurer。現在一切正常，如預期（包括招搖）。另外，要修改contextPath，你必須在你的application.properties中修改這個參數：「server.servlet.context-path」，而不是最後一個支持的「server.contextPath」
