Spring調度程序servlet找不到index.html。在DispatcherServlet中找不到使用URI []的HTTP請求的映射

我一直在試圖獲得一個簡單的spring mvc webapp工作。我或多或少地遵循本教程：http://www.codejava.net/frameworks/spring/spring-mvc-beginner-tutorial-with-spring-tool-suite-ideSpring調度程序servlet找不到index.html。在DispatcherServlet中找不到使用URI []的HTTP請求的映射

請注意，即時通訊使用彈簧3.2.5.RELEASE。除非控制器返回「index」，否則一切都工作正常，調度程序servlet映射到「/websitebasetest/WEB-INF/views/index.html」，即使在「WEB- INF /意見」。

控制器被稱爲是偉大的！但之後，似乎有一個問題發現相關的視圖很奇怪，因爲日誌建議視圖解析器在「/websitebasetest/WEB-INF/views/index.html」（見下文）中找到適當的視圖。

我的問題是，爲什麼它沒有找到視圖（而是顯示404），我如何得到它的工作？

以下是你可能會問的信息：

     logger.info("Hello world!"); 

     return "index";

的index.html：我想

<html> 
<head> 
    <title>Home</title> 
</head> 
<body> 
    <h1>Hello world!</h1> 
</body>

我找到了解決方案。

在servlet上下文我增加：

<resources mapping="/views/**" location="/WEB-INF/views/" />

和編輯這一部分：

<!-- Resolves views selected for rendering by @Controllers to .html resources in the /WEB-INF/webcontent/views directory --> 
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <beans:property name="prefix" value="/views/" /> 
    <beans:property name="suffix" value=".html" /> 
</beans:bean>

的視圖解析器從控制器，其然後改變到「/視圖/索引接收 「索引」。 HTML」。由於我爲任何以「/ views/**」開頭的映射到「/ WEB-INF/views /」的資源添加了資源映射，因此它現在可以正確地找到視圖xD。

似乎被映射到「/websitebasetest/WEB-INF/views/index.html」（這是之前做的）是不正確的，因爲它無法找到該文件。

特別感謝一路上幫助過的人！

我剛剛在我的本地機器上運行了您的整個代碼，以查看我的方式是否正確。 問題出在您的網頁上。XML

<servlet-mapping> 
    <servlet-name>appServlet</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping>

取而代之的是，它應該是

<servlet-mapping> 
      <servlet-name>appServlet</servlet-name> 
      <url-pattern>*.html</url-pattern> 
    </servlet-mapping>

這樣，你的servlet可以處理與.html擴展任何東西。

順便說一句我運行它在碼頭服務器

這沒有奏效。事實上，當我嘗試這個「Hello World」不會出現在控制檯日誌中。這意味着HomeController.index（）沒有被調用... – TenaciousDan

你可以共享一些控制檯日誌嗎？我只是在本地進行了測試，並且工作正常。\ – Sohil

@TenaciousDan我在碼頭服務器上運行的其他修改是失去了所有slf4j依賴關係，並且失去了常見的日誌記錄排除功能。看看它是否適用於您。 – Sohil
