Java 如何在Camel 2.14.1 REST DSL中将响应pojo绑定或转换为XML/JSON

我正在尝试在ApacheCamel中使用RESTDSL

我希望路由能够根据请求负载将响应pojo绑定/格式化为XML或JSON格式。若请求负载为JSON，则响应应为JSON格式，若负载为XML，则响应应为XML格式

然而，这并没有发生。响应始终仅使用XML。当绑定模式为RestBindingMode.json时，只有它给出json响应

请帮我找出我做错了什么！还可以做些什么来获得期望的结果

路线生成器：

restConfiguration().component("servlet").bindingMode(RestBindingMode.json_xml)
            .dataFormatProperty("prettyPrint", "true").contextPath("test/profile").port(8080);

    rest("/getProfile").description("User profile services")

    .post().description("Find profile by ID").type(Request.class).outType(Response.class)
    .to("direct:userId-post");

    from("direct:userId-post").routeId("profileRoute").processRef("profileProcessor");

处理器：

{
Response response = new Response();
Request request = (Request) exchange.getIn().getBody();
List<Profile> profileList = profileService.getProfile(request.getId()); // Calling method to populate the list
response.setStatusCode("200");
response.setStatusDesc("success");
response.setStatusType("SUCCESS");
response.setUserProfiles(profileList);
exchange.getOut().setBody(response);
}   

答复POJO：

@XmlRootElement(name = "profiles")
@XmlAccessorType(XmlAccessType.FIELD)
public class Response {
    @XmlElement(name = "statusCode")
    private String statusCode;
    @XmlElement(name = "statusDescription")
    private String statusDesc;
    @XmlElement(name = "statusType")
    private String statusType;
    @XmlElement(name = "profile")
    private List<Profile> userProfiles;
    // Getters-Setters
}

将内容类型头设置为application/json以获取json。我已经尝试过了。但它不起作用。无论我传递application/json还是application/xml，它都只给出xml响应。然而，要补充的是，当我将内容类型的值指定为application/json时，json负载是不被接受的。它抛出javax.xml.bind.UnmarshalException我正在为此使用RESTClient。请确保在ClassPath上有camel jackson我在pom中添加了camel jaxb和camel jackson依赖项，我可以在Libraries>Maven依赖项中看到这些JAR

@XmlRootElement(name = "profiles")
@XmlAccessorType(XmlAccessType.FIELD)
public class Response {
    @XmlElement(name = "statusCode")
    private String statusCode;
    @XmlElement(name = "statusDescription")
    private String statusDesc;
    @XmlElement(name = "statusType")
    private String statusType;
    @XmlElement(name = "profile")
    private List<Profile> userProfiles;
    // Getters-Setters
}
