我已经在 web.xml 中提供了我的欢迎文件但是在运行应用程序时，它在 http://172.16.2.16:8080/sampletest/

上显示 404 错误

这是一个 spring 应用程序。

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    id="WebApp_ID" version="3.1">
    <display-name>sampletest</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

    <!-- Spring MVC -->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

我正在使用 eclipse luna、java 8、tomcat 8 和 maven 框架。index.html 文件直接在 webapp 文件夹下，web.xml 在 webapp/WEB-INF 文件夹下。如果我使用 index.jsp 而不是 index.html，它就可以工作。然后将使用 http://172.16.2.16:8080/sampletest/

加载欢迎页面

问题仅与欢迎文件有关。否则 Spring 配置正在工作。http://localhost:8080/sampletest/test/ 将从数据库加载数据。

控制台报错

最佳答案

尝试添加 <mvc:default-servlet-handler/>在您的 dispatcher-servlet.xml 中。
