Apache Camel: Covert JSON to a POJO using camel methods
提问by Sikorski
I have a REST server which sends JSON in response body. I have recently started reading about Apache Camel. I use following to send requests to my REST service.
我有一个 REST 服务器，它在响应正文中发送 JSON。我最近开始阅读有关 Apache Camel 的文章。我使用以下内容向我的 REST 服务发送请求。
from("direct:start").setHeader("token", simple("234da"))
.to("http://localhost:8088/foo/bar/?foo1=bar1");
Now the response will be a JSON, is there any way I get this JSON directly into a POJO using some method ahead of to()(something like this)?
现在响应将是一个 JSON，有什么方法可以使用某种方法将这个 JSON 直接放入 POJO 中to()（类似这样）？
to("http://localhost:8088/foo/bar/?foo1=bar1").toPOJO();
I would prefer a non Spring solution.
我更喜欢非 Spring 解决方案。
Thanks
谢谢

Apache Camel provides a component to marshal and unmarshal POJO to and from JSON.
Apache Camel 提供了一个组件来对 POJO 与 JSON 进行编组和解组。
In your case, it would be :
在您的情况下，它将是：
from("direct:start").setHeader("token", simple("234da"))
.to("http://localhost:8088/foo/bar/?foo1=bar1")
.unmarshal().json();
By the way, you may need to configure your json library to do it and I suggest you take look at the official configuration.
顺便说一句，您可能需要配置您的 json 库才能做到这一点，我建议您查看官方配置。

Little details from my side - although late
我身边的小细节——虽然晚了
Create jsonFormatter and then unmarshal with class you needJsonDataFormat jsonDataFormat = new JsonDataFormat(JsonLibrary.Hymanson);
this can be used in marshalling
创建 jsonFormatter 然后用你需要的类解组JsonDataFormat jsonDataFormat = new JsonDataFormat(JsonLibrary.Hymanson);
这可以在编组中使用
from("direct:consume-rest").log("calling bean method...").to("http://localhost:8080/greeting?name=baba")//.process(svProcessor) // any extra process if you want.unmarshal().json(JsonLibrary.Hymanson, Greeting.class).bean(GreetingHelper.class, "print").log("converted to bean ...").end();
from("direct:consume-rest").log("calling bean method...").to("http://localhost:8080/greeting?name=baba")//.process(svProcessor) // any extra process if you want.unmarshal().json(JsonLibrary.Hymanson, Greeting.class).bean(GreetingHelper.class, "print").log("converted to bean ...").end();
Helper class methodpublic void print (@Body Greeting greeting) {
辅助类方法public void print (@Body Greeting greeting) {
