Tomcat上的Spring Security SAML元数据URL

Tomcat上的Spring Security SAML元数据URL

tomcat

我正在开发基于Java的Web应用程序，并在Tomcat服务器上使用Spring Security
SAML实现SSO。该应用程序将扮演服务提供商角色（SP）。检索此SP的元数据的默认Spring URL为：

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

这工作得很好，可以按预期返回元数据XML文件。但是，将 DefaultServlet Servlet映射添加到web.xml
时遇到问题。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>

如果web.xml中存在一个或多个默认servlet映射，则上述URL返回404。有人知道是什么原因引起的，并且有可能的解决方法？

更新：我已经从上面将确切的servlet映射放入了Spring Security
SAML示例应用程序中，并且它还阻止了元数据URL的工作。如果我将其注释掉或将其删除，它将按预期工作。以下是该web.xml：

<?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Spring SAML 1.0.0.RELEASE通过执行以下步骤来重现您的问题：

下载的Spring SAML源
换成sample/src/main/webapp/WEB-INF/web.xml你的web.xml
使用启动了示例应用程序 gradlew build tomcatRun

但我无法重现您的问题，一切都会按预期进行。该问题可能特定于某些Tomcat版本，请尝试按照我的步骤重现该问题，并最终尝试更改您的Tomcat版本。

更新：

正如您提到的，当直接部署到Tomcat时，我能够复制它。该defaultservlet的似乎跳过在定义的过滤器执行/*。以下配置将为您工作：

<?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"

确保更改文件org.springframework.security.saml.web.MetadataController并替换@RequestMapping("/metadata")为@RequestMapping("/saml/web/metadata")
