如何将JAXBElement编组为Response？ [英] How to marshal JAXBElement into Response?

问题描述

我的 CXF 提供 REST 服务通常返回 javax.ws.rs.core。响应通常的原因是，将结果实体数据封装为XML并返回代码：

My CXF provided REST services usually return javax.ws.rs.core.Response for the usual reason, to encapsulate the result entity data marshaled as XML and a return code:

@GET
@Path("/getPojo")
@Produces("application/xml")
public Response getPojo() {

    SomePojo resultObj = ...;

    Response result = Response.status(200).entity(resultObj).build();

    return result;
}

需要 SomePojo 包含正确的注释：

@XmlRootElement(name = "somePojo")
@XmlAccessorType(XmlAccessType.FIELD)
public class SomePojo implements Serializable {
    ...
}

但是，现在我面临的情况是注释约定对我不起作用，我必须构建自己的 JAXBElement 。如何在 Response 中包含自定义封送的JAXBElement，而不是使用 Response.ResponseBuilder.entity（resultObj），哪个依赖于注释配置？我正在整理类似此处的内容。但他只是将封送的XML打印到控制台中，我想将它打印到Response中（而不仅仅是 HttpResponse out）。

However, now I am facing a scenario where the annotation convention does not work for me and I have to build my own JAXBElement. How can I include the custom-marshaled JAXBElement in the Response instead of using Response.ResponseBuilder.entity(resultObj), which relies on the annotation configuration? I am marshaling something similar to what is explained here but he's just printing the marshaled XML into the console and I would like to print it into the Response (and not just HttpResponse out).

推荐答案

您可以使用自定义编组器对xml进行编组，并在响应的实体中设置结果XML， as String 或 InputStream

You can marshall the xml using your custom marshaller and set the resultant XML in the entity of the Response, as String or InputStream

@GET
@Path("/getXML")
@Produces("application/xml")
public Response getXML() {

    String xml = // custom marshall

    Response result = Response.
           status(200).
           entity(xml).
           type("application/xml").
           build();

    return result;
}
