Spring MVC中找不到類異常

Question

我遇到了這個異常，但是當我查看MAVEN DEPENDENCIES文件夾時，可以看到pom.xml正確下載了所有類。

對於類似的問題，我已經引用了堆棧溢出提供的所有其他答案。 我的項目也成功建立。

Answer 1

我刪除了Maven存儲庫文件夾.repository

並更新了eclipse中的所有依賴項，然后解決了這個問題

Answer 2

在web.xml使用以下命令：

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/context.xml</param-value>
    </context-param>

    <!-- Spring Context Listener -->
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

Answer 3

我刪除了“目標”目錄中的war文件，重新啟動了eclipse，然后在maven中進行了全新安裝。 這解決了我的問題。
