It appears you might be using an incompatible version of the library. I think the class org.springframework.security.web.access.intercept.FilterSecurityInterceptor is not extending the class javax.servlet.Filter.

NOTE: The link to example repository seems to be broken.

[guruscott-meyer]

Correct. Not only has the org.springframework.security.web.access.intercept.FilterSecurityInterceptor class been deprecated for years, it was removed in the latest release.

@guruscott-meyer That is not true. FilterSecurityInterceptor was not removed. It is only deprecated and should be around at least until Spring Security 7 is released which won't for another year from now. ~ November 2025.
