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
