MICROSERVICES FOR BEGINNERS

Comment

A microservices architecture consists of small, autonomous services, and each one is self-contained and implements a single business capability

@SpringBootApplication
@EnableDiscoveryClient
@ComponentScan(useDefaultFilters=false)  // Disable component scanner
public class WebServer {

    // Case insensitive: could also use: http://accounts-service
    public static final String ACCOUNTS_SERVICE_URL
                                        = "http://ACCOUNTS-SERVICE";

    public static void main(String[] args) {
        // Will configure using web-server.yml
        System.setProperty("spring.config.name", "web-server");
        SpringApplication.run(WebServer.class, args);
    }

    @LoadBalanced    // Make sure to create the load-balanced template
    @Bean
    RestTemplate restTemplate() {
        return new RestTemplate();
    }

    /**
     * Account service calls microservice internally using provided URL.
     */
    @Bean
    public WebAccountsService accountsService() {
        return new WebAccountsService(ACCOUNTS_SERVICE_URL);
    }

    @Bean
    public WebAccountsController accountsController() {
         return new WebAccountsController
                       (accountsService());  // plug in account-service
    }
}

• There is no "one size fits all" approach when implementing microservices. In

this section, different examples are analyzed to crystalize the microservices

concept.

• Fly By Points collects points that are accumulated when a customer books a

hotel, flight, or car through the online website. When the customer logs in to

the Fly By Points website, he/she is able to see the points accumulated,

personalized offers that can be availed of by redeeming the points, and

upcoming trips if any.

• Let's assume that the following page is the home page after login. There are

two upcoming trips for Jeo, four personalized offers, and 21,123 loyalty

points. When the user clicks on each of the boxes, the details are queried

and displayed

@EnableAutoConfiguration
@EnableDiscoveryClient
@Import(AccountsWebApplication.class)
public class AccountsServer {

    @Autowired
    AccountRepository accountRepository;

    public static void main(String[] args) {
        // Will configure using accounts-server.yml
        System.setProperty("spring.config.name", "accounts-server");

        SpringApplication.run(AccountsServer.class, args);
    }
}
