Какой опыт работы с авторизацией

String token = Jwts.builder()
    .setSubject(username)
    .setExpiration(new Date(System.currentTimeMillis() + EXPIRATION_TIME))
    .signWith(SignatureAlgorithm.HS512, SECRET_KEY)
    .compact();

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/public/**").permitAll()
            .anyRequest().authenticated()
            .and()
            .oauth2ResourceServer().jwt();
    }
}
