Token-based authentication is a protocol which allows users to verify their identity, and in return receive a unique access token.

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
  @Value("${auth0.audience}")
  private String audience;

  @Value("${spring.security.oauth2.resourceserver.jwt.issuer-uri}")
  private String issuer;

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
      .mvcMatchers(HttpMethod.GET, "/api/menu/items/**").permitAll() // GET requests don't need auth
      .anyRequest()
      .authenticated()
      .and()
      .oauth2ResourceServer()
      .jwt()
      .decoder(jwtDecoder());
  }

  JwtDecoder jwtDecoder() {
    OAuth2TokenValidator<Jwt> withAudience = new AudienceValidator(audience);
    OAuth2TokenValidator<Jwt> withIssuer = JwtValidators.createDefaultWithIssuer(issuer);
    OAuth2TokenValidator<Jwt> validator = new DelegatingOAuth2TokenValidator<>(withAudience, withIssuer);

    NimbusJwtDecoder jwtDecoder = (NimbusJwtDecoder) JwtDecoders.fromOidcIssuerLocation(issuer);
    jwtDecoder.setJwtValidator(validator);
    return jwtDecoder;
  }
}
