Spring MVC + Thymeleaf java.io.IOException：文件名，目錄名稱或卷標語法不正確

Question

我正在Spring MVC框架上構建一個Web應用程序，並使用thymeleaf作爲我的模板引擎。

在添加新的REST控制器之前，我有一個工作應用程序。一個IOException現在拋出

產生java.io.IOException：文件名，目錄名或卷標語法不正確

當瀏覽器嘗試獲取的CSS這只是發生，JS或來自我的taoConnection-servlet.xml的任何其他靜態資源。我的jetty和tomcat7部署都發生同樣的情況。經過幾個小時的搜索後，我找不到任何類似的問題。

編輯：我正在調用/帳戶請求映射，但它發生在所有訪問靜態資源的請求映射。如果我嘗試直接在瀏覽器中訪問資源，例如http://localhost:8080/css/bootstrap.min.css或http://localhost:8080/js/sb-admin-2.js引發異常。

或者，如果我嘗試訪問假資源，例如http://localhost:8080/js/fake.js我仍然得到一個標準的http 404，這是預期的，但不拋出IOException。

試試這個：

<mvc:resources mapping="/css/**" location="/css/" /> 
<mvc:resources mapping="/js/**" location="/js/" /> 
<mvc:resources mapping="/font-awesome-4.1.0/**" location="/font-awesome-4.1.0/" />
