Tomcat上的Spring Security SAML元数据URL

Question

我正在开发一个基于Java的web应用程序，在Tomcat服务器上使用Spring Security SAML实现SSO。此应用程序将扮演服务提供者的角色(SP)。检索此SP元数据的默认Spring URL是：

https://www.server.com:8080/context/saml/metadata

这样做很好，按预期返回元数据XML文件。但是，当我向web.xml添加DefaultServlet servlet-mappings时，我遇到了一个问题。甚至只是一些基本的东西：

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.gif</url-pattern>
</servlet-mapping>

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

我尝试用Spring SAML 1.0.0..发布，通过以下步骤重现您的问题：

• 下载的Spring SAML源代码
• 用您的web.xml
替换了 sample/src/main/webapp/WEB-INF/web.xml
• 使用Gradlew build Tomcatrun
启动示例应用程序

但我无法再现你的问题，一切都在继续正常运转。这个问题可能是特定于某个Tomcat版本的，请尝试用我的步骤重现它，并最终尝试更改您的Tomcat版本。

确保更改文件org.springframework.security.saml.web.metadataController并将@requestmapping（“/saml/web/metadata”）替换为@requestmapping（“/saml/metadata”）
