Configuring JWT Token Services in axon

Imported from Google Groups

Hi all
I’m trying to configure spring security with OAuth and JWT tokens.Here’s a config of in the resourse server:

@Override
public void configure(ResourceServerSecurityConfigurer config) {
    config.tokenServices(tokenServices());
}

@Bean
@Qualifier("tokenStore")
public TokenStore tokenStore() {
    return new JwtTokenStore(accessTokenConverter());
}

@Bean
public JwtAccessTokenConverter accessTokenConverter() {
    JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
    Resource resource = new ClassPathResource("public.txt");
    String publicKey = null;
    try {
        publicKey = IOUtils.toString(new FileReader(resource.getFile()));
    } catch (final IOException e) {
        throw new RuntimeException(e);
    }
    converter.setVerifierKey(publicKey);
    return converter;
}

@Bean
@Primary
public DefaultTokenServices tokenServices() {
    DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
    defaultTokenServices.setTokenStore(tokenStore());
    return defaultTokenServices;
}

When i run the application, I get the following error:

`

My tokenstore bean implementation is being overriden by axon’s tokenstore. How do I bypass that?

If you rename your tokenStore() method (the one returning the JWT token), that should resolve the issue. Alternatively, you can specify a beanName in the @Bean annotation on that method.

Thanks Allard.
