如何使用 vertx.eventBus().send() 方法将 RoutingContext 对象从路由 Verticle 发送到其他 Verticle?

问题描述

从具有路由 URL 的路由顶点，我想将 RoutingContext 对象发送到另一个顶点.我相信我们只能使用 vertx.eventBus().send() 将消息从路由顶点发送到其他动作顶点.我可以将 RoutingContext 对象作为消息发送吗?

From my routing verticle which has route URL, I want to send RoutingContext object to another verticle. I believe we can only use vertx.eventBus().send() to send message from routing verticle to some other action verticle. Can I send RoutingContext object as a message?

在路由器垂直我正在做vertx.eventBus().send("address", routingContext)

在消费者verticle中我正在做vertx.eventBus().consumer("address").handler(message -> {RoutingContext routingContext = message.body();LOGGER.info("routingContext body = "+routingContext.getBodyAsString());});

and in consumer verticle I am doingvertx.eventBus().<RoutingContext>consumer("address").handler(message -> { RoutingContext routingContext = message.body(); LOGGER.info("routingContext body = "+routingContext.getBodyAsString());});

但看起来vertx本身无法执行'vertx.eventBus().send'谁能告诉我如何使用 vertx.eventBus().send 方法发送 RoutingContext 对象?

but looks like vertx itself is not able to execute 'vertx.eventBus().send'Could anyone please let me know how could I send RoutingContext object using vertx.eventBus().send method?

推荐答案

如果你想通过 Vert.x EventBus 发送一个对象，它不是 JsonObject 或像 String 这样的普通 Java 对象，例如，您需要实现自己的编解码器.

If you want to send an object over Vert.x EventBus which is not a JsonObject or a plain Java object like a String, for example, you need to implement your own codec.

这意味着基本上描述了您要传输对象的哪些部分.

What that means is basically describing which parts of the object you want to transfer.

您可以在此处查看实现自定义编解码器的示例:

You can see examples of implementing your custom codec here:

https://github.com/vert-x3/vertx-examples/blob/master/core-examples/src/main/java/io/vertx/example/core/eventbus/messagecodec/util/CustomMessageCodec.java

在我看来，为 RoutingContext 实现它仍然没有多大意义.只传输您实际需要的部分，而不是整个对象.

It still doesn't make much sense to implement it for RoutingContext, in my opinion. Just transfer the parts that you actually need, not the entire object.
