在名称为'dispatcher'的DispatcherServlet中找不到带有URI [/app/j_spring_security_login]的HTTP请求的映射 [英] No mapping found for HTTP request with URI [/app/j_spring_security_login] in DispatcherServlet with name 'dispatcher'

问题描述

我将此登录链接添加到了我的Spring应用程序:

I added this login link to my Spring app:

<a href="<spring:url value="/j_spring_security_login" htmlEscape="true" />">
Sign In
</a>

我的假设是，因为这是用于访问登录页面的内置标签，所以Spring会知道如何将其与适当的处理程序相关联，而无需我明确地指定它.

My assumption was that because this is a built-in tag for accessing the login page, Spring would know how to associate this with an appropriate handler without me having to specify it explicitly.

但是，它会产生以下错误:

However, it generates the following error:

org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI 
[/app/j_spring_security_login] in DispatcherServlet with name 'dispatcher'

为此URL定义处理程序的合适方法是什么?

What's the appropriate way to define the handler for this URL?

推荐答案

/j_spring_security_login是Spring Security的特殊URL，因此它由Spring Security过滤器处理，您无需为其定义任何其他处理程序.只需检查您是否具有正确配置和映射的Spring Security过滤器，如

/j_spring_security_login is a special Spring Security's url, so it's handled by the Spring Security filter and you don't need to define any other handler for it. Just check that you have a properly configured and mapped Spring Security filter, as described here.
