Chained Methods

In the configure method for Spring Security, we see code like this:

http
        .authorizeRequests()
            .antMatchers("/","/login**","/webjars/**","/error**")
            .permitAll()
        .anyRequest()
            .authenticated();

This is equivalent to:

http.authorizeRequests();
http.antMatchers("/","/login**","/webjars/**","/error**");
http.permitAll();
http.anyRequest();
http.authenticated();

We also discussed that the forEach and the for loop here are equivalent:

         Iterable<ClientRegistration> iterable;
         iterable = ((Iterable<ClientRegistration>) clientRegistrationRepository);
-        iterable.forEach(clientRegistration -> urls.put(clientRegistration.getClientName(),
-                "/oauth2/authorization/" + clientRegistration.getRegistrationId()));
+        // cr = clientRegistration
+        // iterable.forEach(cr -> urls.put(cr.getClientName(),"/oauth2/authorization/" + cr.getRegistrationId()));
+
+        for (var cr : iterable) {
+            urls.put(cr.getClientName(),"/oauth2/authorization/" + cr.getRegistrationId());
+        }
+
