how to get Keycloak access token and store it in db for spring boot? - mysql

Question

i want get the access token first and store the access token generated by keycloak during login... in my db. i am using spring boot .
this is the code that i tried for getting the access token ..but result is nothing.... have a better solution?
..
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String getCustomers()
{
HttpServletRequest request =((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes())
.getRequest();
KeycloakAuthenticationToken token = (KeycloakAuthenticationToken) request.getUserPrincipal();
KeycloakPrincipal principal = (KeycloakPrincipal) token.getPrincipal();
KeycloakSecurityContext session = principal.getKeycloakSecurityContext();
AccessToken accessToken = session.getToken();
String a = principal.getName();
String username = accessToken.getPreferredUsername();
String realmName = accessToken.getIssuer();
AccessToken.Access realmAccess = accessToken.getRealmAccess();
String s = session.getToken().toString();
System.out.println(s);
return realmName;
.. }
i expect to get the access token generated by keycloak and store it in db.
#KeycloakConfiguration class SecurityConfig extends
KeycloakWebSecurityConfigurerAdapter {
/**
* Registers the KeycloakAuthenticationProvider with the authentication manager.
*/
#Autowired public void configureGlobal(AuthenticationManagerBuilder auth)
throws Exception { KeycloakAuthenticationProvider
keycloakAuthenticationProvider=keycloakAuthenticationProvider();
keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new
SimpleAuthorityMapper());
auth.authenticationProvider(keycloakAuthenticationProvider); }
/**
* Defines the session authentication strategy.
*/
#Bean
#Override protected SessionAuthenticationStrategy
sessionAuthenticationStrategy() { return new
RegisterSessionAuthenticationStrategy(new SessionRegistryImpl()); }
#Bean public KeycloakConfigResolver keycloakConfigResolver() { return new
KeycloakSpringBootConfigResolver(); }
#Override protected void configure(HttpSecurity http) throws Exception {
super.configure(http); http .authorizeRequests()
.antMatchers("/login*").hasRole("springrole") .anyRequest().permitAll(); } }
this is my keycloak configuration..
