Is there a Spring interceptor that is called before the UsernamePasswordAuthenticationFilter name?

Question

I want to call a method before UsernamePasswordAuthenticationFilter . attemptAuthentication()called (and before any other requests are processed in the application).

I tried calling the method in the HandlerInterceptorAdapter . preHandle()but this does not work before attemptAuthentication(), although it will take care of other types of queries.

Is there a Spring interceptor that is called before UsernamePasswordAuthenticationFilter?

Answer 1

I think you are talking about the spring security filter chain.

Filters with these names must be called before UsernamePasswordAuthenticationFilter

• FIRST
• CHANNEL_FILTER,
• CONCURRENT_SESSION_FILTER,
• SECURITY_CONTEXT_FILTER,
• LOGOUT_FILTER,
• X509_FILTER,
• PRE_AUTH_FILTER,
• CAS_FILTER,

. org.springframework.security.config.http.SecurityFilters.

before:

<security:custom-filter ref="myFiler" before="FORM_LOGIN_FILTER" />
