Question

我正在开展一个春季项目，我发现这个奇怪的错误，找不到404

当我调用localhost时：8080 / BMS /我收到以下错误

 No mapping found for HTTP request with URI [/BMS/$%7B] in DispatcherServlet with name 'spring'

请注意：我将一个Index.html文件作为webapp文件夹下的欢迎文件重定向到WEB-INF文件夹中的登录页面

所以我的问题是错误中的$%7B是什么以及我如何解决这个问题？

的index.html

<head>
   <meta http-equiv="refresh" content="0; url=http://localhost:8080/BMS/login.html" />
</head>

Web.xml中

Answer 1

根据网址编码，参考%7B表示{

查看index.html的这一行

<meta http-equiv="refresh" content="0; url=http://localhost:8080/BMS/login.html" />

尝试在零＆amp;之间删除空格网址。 将网址设为网址。

<meta http-equiv="refresh" content="0;URL=http://localhost:8080/BMS/login.html" />

希望这会对你有所帮助。

在DispatcherServlet中找不到带有URI [/ BMS / $％7B]的HTTP请求的映射，名称为“spring”
