Quick Start

1. Add Authentication Dependency

implementation libs.bitso.api.base.spring.webapi

2. Configure gRPC Client

grpc:
  client:
    user-security:
      address: dns:/${USER_SECURITY_HOST:localhost}:${GRPC_PORT:8201}
      negotiation-type: PLAINTEXT

3. Create Controller

@RestController
@RequestMapping("/")
public class MyController {

    @Autowired
    SpringHttpResponseFactory responseFactory;

    @Autowired
    WebAuthenticationContext authenticationContext;

    @GetMapping("/private")
    @WebAPI(WebAPIType.PRIVATE)
    public ResponseEntity<?> privateEndpoint() {
        Long userId = authenticationContext.getPrincipalId();
        return responseFactory.ok(userId);
    }
}

Authentication

Configuration Bean

@Configuration
public class UserSecurityContextConfiguration {
    @Bean
    @Primary
    public AuthenticationService authenticationService(
        @GrpcClient("user-security") AuthorizationServiceV1BlockingStub stub,
        @Qualifier("userSecurityResilienceConfig") ResilienceConfiguration config
    ) {
        return new ProtoShimAuthenticationService(config, stub);
    }
}

Component Scan

Ensure your main application scans Bitso components:

@SpringBootApplication
@ComponentScan("com.bitso.*")
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

Documentation

OpenAPI Specification

All endpoints should be documented under ./docs/api/rest/openapi.yaml
