Vertx与Spring配合完成DML操作

服务启动：

  public static void main( String[] args ) {
    ApplicationContext context = new AnnotationConfigApplicationContext(SimpleSpringConfiguration.class);
    final Vertx vertx = Vertx.vertx();
    vertx.deployVerticle(new SpringSimpleVerticle(context));
    vertx.deployVerticle(new ServerVerticle());
  }

 EventBus接受给Service：

public class SpringSimpleVerticle extends AbstractVerticle {
 
    public static final String ALL_PRODUCTS_ADDRESS = "example.all.products";
 
 
    private final ObjectMapper mapper = new ObjectMapper();
    private final ProductService service;
 
    public SpringSimpleVerticle(final ApplicationContext context) {
 
        service = (ProductService) context.getBean("productService");
 
    }
 
    private Handler<Message<String>> allProductsHandler(ProductService service, String name) {
        return ms2g -> vertx.<String>executeBlocking(future -> {
                    try {
                        future.complete(mapper.writeValueAsString(service.getAllProducts(ms2g.body())));
                    } catch (JsonProcessingException e) {
                        System.out.println("Failed to serialize result");
                        future.fail(e);
                    }
                },
                result -> {
                    if (result.succeeded()) {
                        ms2g.reply(result.result());
                    } else {
                        ms2g.reply(result.cause().toString());
                    }
                });
    }
 
    @Override
    public void start() throws Exception {
        super.start();
 
        System.out.println("<<<<<<<<<<<<<<<<<<<<<<< CONSUMER >>>>>>>>>>>>>>>>>>>>>>>>>");
        vertx.eventBus().<String>consumer(ALL_PRODUCTS_ADDRESS).handler(allProductsHandler(service, "message"));
 
    }
}

端口监听：

@Service
public class ProductService {
 
    @Autowired
    private ProductRepository repo;
 
    public List<Product> getAllProducts(String productId) {
        System.out.println("productid : " + productId);
        return repo.findAll();
    }
 
    public void getProduct(String productId) {
        System.out.println("productid : " + productId);
    }
 
}

结论：

DML操作基本都是类似的做法，但是观念的改变其实很大，传统烟囱的方式=》基于消息、事件的方式转移
