獲取，java.lang.IllegalArgumentException異常：路徑的index.html不以「/」字符，訪問招搖的UI

時，我們正在用揚鞭的UI開始 - 1.0.1與揚鞭，用SpringMVC - 1.0.2。最近我們從Spring-boot 1.2升級到1.3.1 &我們在使用swagger-ui時遇到了一個小問題。早些時候，我可以使用http://localhost:8080/application-context但自從升級到spring-boot 1.3.1以來，我們必須添加一個斜線來訪問sawgger-ui。雖然試圖不斜線來訪問它，我得到java.lang.IllegalArgumentException異常：路徑的index.html不以「/」字符獲取，java.lang.IllegalArgumentException異常：路徑的index.html不以「/」字符，訪問招搖的UI

是否升級其造成了這種行爲？

我覺得麻煩的是與（嵌入式）的Tomcat 8.0.30版本，其中彈簧啓動1.3.1（1.3.2和）使用爲dependency。最簡單的解決方案可能是使用Tomcat 8.0.28或8.0.32或更新版本（使用Maven依賴關係管理來使用替代/更新版本的Tomcat）。

下面涉及的錯誤修正（取自Tomcat的8.0 change-log）：

的Tomcat 8.0.29
移動提供重定向爲上下文根和目錄，其中一個尾隨從映射器添加/向功能DefaultServlet。這使得這些請求能夠在重定向之前由任何配置的閥門和過濾器進行處理。此行爲可通過可用於恢復先前行爲的Context的mapperContextRootRedirectEnabled和mapperDirectoryRedirectEnabled屬性進行配置。

的Tomcat 8.0.30
58660修正因感動的上下文根重定向從映射到默認的servlet的變化在8.0.29迴歸。

的Tomcat 8.0.31
58765 變化的，因爲這mapperContextRootRedirectEnabled到true默認需要正確的會話管理，因爲默認爲sessionCookiePathUsesTrailingSlash的。

是的，是有道理的。謝謝，會試試這個。 – Amrut

對不起，沒有更新，但它的工作。再次感謝。 – Amrut

我覺得這是應該做你的代碼的源代碼級別，我所看到的這個問題發生時，更新的源代碼級別從1.7到1.8。當你下坡回1.7，然後一切似乎是工作像一個魅力。如果你真的想升級你的源代碼級別，那麼試着升級所有依賴項，它們可以很好地適用於1.8源代碼級別
