SpringBootWebXmlServlet无法在Web应用程序启动时预加载：“/”

Question

我试图集成一个旧的weblogic应用程序来使用Okta SSO saml2.0流。我已经成功地使用@ServletCompenentScan将应用程序与Spring Boot集成，并且能够成功地使用Spring Security性进行基本身份验证。但是，当将特定于SAML的配置添加到SecurityConfiguration时，应用会在部署时失败。对于okta saml，我遵循这个教程https://developer.okta.com/blog/2017/03/16/spring-boot-saml.Weblogic版本是12.2.1.3.0

The app deploys fine with the base spring security without the Okta Dependency.

Answer 1

多亏了Matt提供的链接，我找到了问题的答案。

There were conflicting dependencies being pulled in so I had to specify the preferred ones in the weblogic.xml
Heres the code.
