[英]how to create an REST API then the REST API will put object/string to ActiveMQ
i am trying to implement spring-boot camel.我正在尝试实现 spring-boot 骆驼。 i should create an REST API then the REST API will put object/string to ActiveMQ.我应该创建一个 REST API,然后 REST API 会将对象/字符串放入 ActiveMQ。 i have done :我已经做好了 :
rest("/test/").description("Teste REST Service")
.id("api-route")
.post("/bean")
.consumes(MediaType.APPLICATION_JSON_VALUE)
.produces(MediaType.APPLICATION_JSON_VALUE)
.bindingMode(RestBindingMode.auto)
.type(User.class)
.enableCORS(true)
.to("seda:next");
from("seda:next")
.routeId("direct-route")
.tracing()
.log(">>> ${body.id}")
.log(">>> ${body.name}")
.transform().simple("Hello ${in.body.name}")
.to("activemq:queue:foo")
// .to("direct:remoteService1")
;

If you are not expecting a reply from your message into your foo queue, then you need to tell activeMQ you are not expecting a reply by sending an inOnly type exchange, or it will create a temporary queue and await a reply:如果您不希望从您的消息回复到您的 foo 队列,那么您需要通过发送 inOnly 类型交换来告诉 activeMQ 您不希望收到回复,否则它将创建一个临时队列并等待回复:
from("seda:next")
.routeId("direct-route")
.tracing()
.log(">>> ${body.id}")
.log(">>> ${body.name}")
.transform().simple("Hello ${in.body.name}")
.inOnly("activemq:queue:foo")
This will result in your "Hello Name" message being returned as the result of the seda:next
, and thus to the rest call.这将导致您的“Hello Name”消息作为seda:next
的结果返回,从而返回到 rest 调用。
Alternatively, you could have或者,你可以有
.inOnly("seda:next")
in your first route if you don't want a response from the "next" route, which I think would mean that your rest call would get the original input class as the response (but don't quote me on that).在您的第一条路线中,如果您不想要来自“下一个”路线的响应,我认为这意味着您的休息调用将获得原始输入类作为响应(但不要引用我的话)。
