问题
Front end of my spring-boot service gets rendered in a 3rd party dashboard. That dashboard also has a generic search bar which we want to use. Now, once we implemented Keycloak authentication, we started facing problems specifically in this search bar. All the other API's works fine because they are called from my front end only, But search API gets called by the 3rd party dashboard.
Weirdly, 3rd party calls my method using Http OPTION method, but my endpoint is registered as GET.
For an interim fix, we are trying to disable the auth on search API only and does not seems to work at all. My configurer is:
@KeycloakConfiguration
@Profile("!local") // in local profile InsecureLocalConfigurer must be included instead
public class KeycloakSecurityConfigurer extends KeycloakWebSecurityConfigurerAdapter {
/**
* Enable Keycloak configuration over Spring Boot config instead of {@code keycloak.json} file.

I've tried multiple approaches but none of them works. Sometimes I start getting CORS exception, once I fix it, it again starts throwing unauthorised user error. Kindly help in identifying what I am doing wrong.
Stuff which I tried yet:
super.configure(http); http.csrf().disable(); http .cors() .and() .authorizeRequests() .antMatchers("/health", "/error").permitAll() .antMatchers(HttpMethod.OPTIONS, "/**").permitAll() .anyRequest().authenticated();@Override public void configure(final WebSecurity web) { web.ignoring().antMatchers(HttpMethod.OPTIONS, "/**"); }` http.csrf().disable();
http .cors() .and() .authorizeRequests() .antMatchers("/health", "/error").permitAll() .antMatchers(HttpMethod.OPTIONS, "/item/search").permitAll() .antMatchers(HttpMethod.OPTIONS, "/item/search/").permitAll() .antMatchers(HttpMethod.OPTIONS, "/item/search/**").permitAll() .antMatchers(HttpMethod.OPTIONS, "/**/search").permitAll() .antMatchers(HttpMethod.OPTIONS, "/**/search/").permitAll() .antMatchers(HttpMethod.OPTIONS, "/**/search/**").permitAll() .anyRequest().authenticated();`
