Apache Camel jackson unmarshaller dont work

Question

Im using camel and jackson for unmarshalling string with json

{"GUID":"123"}


... .unmarshal().json(JsonLibrary.Jackson, TestPojo.class)

And hava pojo

    TestPojo {
     @JsonProperty("GUID)
     private String guid;

     @JsonProperty("GUID")
     public String getGuid(){
      return guid;
     }
     @JsonProperty("GUID")
     public String setGuid(){
      return guid;
     }
    }

But have this exception:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "GUID" (class package.TestPojo), not marked as ignorable (1 known properties: "guid")

Im tested route with processor, which work fine

        .process(e -> {
            ObjectMapper mapper = new ObjectMapper();
            e.getIn().setBody(mapper.readValue(e.getIn().getBody(String.class),TestPojo.class));
        })

What im doing wrong?

Answer 1

Your setguid is returning the guid in lowercase. However, in the json body, the guid is capitalized (GUID). Try to capitalize the guid or set.

public void setGUID(String GUID){
  this.GUID = GUID 

}
