在Eclipse中运行简单的Web项目时，我遇到了一个问题.
I am facing an issue in while running simple web project in Eclipse.
我将首先演示创建项目的步骤:-
I will first demonstrate the steps of creating my project :-
1)新的Spring模板项目.
2)选择Spring MVC项目.
3)单击完成.
4)现在，我在"src"下的"webapps"文件夹中创建一个新文件名"login.html".
5)现在，我尝试在web.xml中添加welcome-file标记.
6)当我这样做时，我从Eclipse的web.xml中得到了上面的警告.
7)如果我运行该应用程序，则会收到404错误
1) New Spring Template Project.
2) Select Spring MVC Project.
3) Click Finish.
4) Now I create a new file name "login.html" in "webapps" folder under "src"
5) Now I tried to add welcome-file tag in the web.xml.
6) When I do that I get the above Warning inside web.xml from Eclipse.
7) If I run the application I get 404 error
这是我的web.xml
This is my web.xml
<?xml version="1.0" encoding="UTF-8"?>

</welcome-file-list>
这是我的login.html

预先感谢.
Kindly help me out of this I am not understanding what exactly the error is.

推荐答案
如果您希望欢迎文件工作，请尝试如下更改 servlet映射:
If you want your welcome file to work then try changing your servlet-mapping like below:
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/something/</url-pattern>
</servlet-mapping>
当前，所有请求都将发送到Spring的调度程序servlet，并查找"/"的请求映射.在这种情况下，需要一个Controller处理对"/"的请求，该请求将以视图形式返回login.html.您可以在此处查看一个快速入门的例子.
Currently all the requests are going to Spring's dispatcher servlet and looks for a request mapping for "/". In this case a Controller is required to handle the request for "/" that will return login.html as view. You can look here for a quick start example.
