我在 web.xml 中提供了欢迎文件但是在运行应用程序时,它显示 404 错误http://172.16.2.16:8080/sampletest/
这是一个弹簧应用程序。
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<welcome-file>index.html</welcome-file>

<!-- Spring MVC -->

</servlet>
<servlet-mapping>

</web-app>
我正在使用 eclipse luna、java 8、tomcat 8 和 maven 框架。index.html 文件直接位于 webapp 文件夹下,web.xml 位于 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。然后欢迎页面将使用http://172.16.2.16:8080/sampletest/
问题仅在于欢迎文件。否则弹簧配置正在工作。
http://localhost:8080/sampletest/test/
将从数据库加载数据。
错误登录控制台
