问题

I'm working on a pass-through REST service in Apache Camel. Exposed an end point with jetty component which invokes another REST end point which responds with JSON like below. But when I hit the exposed URL of Camel in a browser not getting desired output. Since I just started working on Camel, any help would be highly appreciated.

from("jetty:http://0.0.0.0:8080/api/camel/appoverview")
		.to("http4://10.150.60.237:80/api/itsb/applicationoverview?httpMethod=GET&bridgeEndpoint=true&throwExceptionOnFailure=false")
		.transform().simple("<out>${body}</out>")
		.log("Response sent -> ${body}");

Getting output -

<out> {
         "applicationId": "1",
         "applicationName": "NetInfo",
         "serviceNoticeCount": "13",
         "operationalStatus": {
            "id": "2",
            "status": "red",
            "statusLevel": "3"
         }
      }
</out>

Desired output -

 {
         "applicationId": "1",
         "applicationName": "NetInfo",
         "serviceNoticeCount": "13",
         "operationalStatus": {
            "id": "2",
            "status": "red",
            "statusLevel": "3"
         }
  }

from("jetty:http://0.0.0.0:8080/api/camel/appoverview")
		.to("http4://10.150.60.237:80/api/itsb/applicationoverview?httpMethod=GET&bridgeEndpoint=true&throwExceptionOnFailure=false")
		.transform().simple("<out>${body}</out>")
		.log("Response sent -> ${body}");

<out> {
         "applicationId": "1",
         "applicationName": "NetInfo",
         "serviceNoticeCount": "13",
         "operationalStatus": {
            "id": "2",
            "status": "red",
            "statusLevel": "3"
         }
      }
</out>

 {
         "applicationId": "1",
         "applicationName": "NetInfo",
         "serviceNoticeCount": "13",
         "operationalStatus": {
            "id": "2",
            "status": "red",
            "statusLevel": "3"
         }
  }

以下是您要翻译的部分：

"from("jetty:http://0.0.0.0:8080/api/camel/appoverview")
.to("http4://10.150.60.237:80/api/itsb/applicationoverview?httpMethod=GET&bridgeEndpoint=true&throwExceptionOnFailure=true")
.unmarshal().json(JsonLibrary.Jackson)
.transform().simple("${body}")
.log("Response sent -> ${body}");"

"unmarshalling needs to be added in pom.xml

<dependency>
			<groupId>org.apache.camel</groupId>
			<artifactId>camel-jackson</artifactId>
</dependency>
```"

It worked after unmarshalling the JSON reply like below -

from("jetty:http://0.0.0.0:8080/api/camel/appoverview")
.to("http4://10.150.60.237:80/api/itsb/applicationoverview?httpMethod=GET&bridgeEndpoint=true&throwExceptionOnFailure=true")
.unmarshal().json(JsonLibrary.Jackson)
.transform().simple("${body}")
.log("Response sent -> ${body}");

Dependency for unmarshalling needs to be added in pom.xml

<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-jackson</artifactId>
</dependency>
