This article introduces the knowledge of "Java Spring Cloud how to create account services". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

account service

Create a basic Spring Boot project named cloud-account.

The following dependency coordinates should be in the final pom. xml:

org.springframework.boot spring-boot-starter-data-mongodb-reactive org.springframework.boot spring-boot-starter-webflux org.springframework.cloud spring-cloud-starter-netflix-eureka-client org.projectlombok lombok true io.projectreactor reactor-test test

Configuration file application.yml

spring: application: name: cloud-accountserver: port: 8100eureka: client: service-url: defaultZone: http://localhost:8000/eureka/

Create the entity class of the account, where @AllArgsConstructor,@NoArgsConstructor and @Data are all comments provided by Lombok. Those who don't know can learn by themselves. I won't say more here.

@AllArgsConstructor@NoArgsConstructor@Data@Document(collection = "accounts")public class Account { @Id private String id; private String customerId; private Double amount;}

Spring Data Reactive. Corresponding to CrudRepository of non-responsive Spring Data, responsive Spring Data also provides the corresponding Repository library: ReactiveCrudRepository, and we can also use its sub-interface ReactiveMongoRepository.

public interface AccountMongoReactiveRepository extends ReactiveCrudRepository { Flux findByCustomerId(String customerId);}

Create a corresponding Controller for the account service. Here, we simply provide an interface to query all accounts of the customer. To test Load Balancer later, a print of the invocation timestamp is added.

@RequestMapping("/account")@RestControllerpublic class AccountController { @Autowired private AccountMongoReactiveRepository repository; @GetMapping("/customer/{customer}") public Flux findByCustomer(@PathVariable(name = "customer") String customer) { System.out.println("Customer => " + customer + " [ " + LocalDateTime.now().format(DateTimeFormatter.ofPattern("HH:mm:ss.SSS")) + " ]"); return repository.findByCustomerId(customer); }}"Java Spring Cloud how to create account services" content introduced here, thank you for reading.
