Question

我使用JAX-RS 2.0（Jersey）实现了以下方法：

@PUT
@Path("container/{containername}/catalog")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response updateCatalog(@PathParam("containername") String containerName, 
        @FormDataParam("catalog") SIRFCatalog catalog) throws IOException, URISyntaxException {
    log.info("Unmarshalling config...");
    SIRFConfiguration config = new SIRFConfigurationUnmarshaller().
            unmarshalConfig(new String(Files.readAllBytes(Paths.get(
            SIRFConfiguration.SIRF_DEFAULT_DIRECTORY + "conf.json"))));
    log.info("Creating strategy...");
    StorageContainerStrategy strat = AbstractStrategyFactory.createStrategy(config);
    log.info("Pushing catalog...");
    strat.pushCatalog(catalog, containerName);

    log.info("Sending response...");
    return Response.ok(new URI("sirf/container/" + containerName + "/catalog")).build();
}

我正在使用Eclipse MOXy，War文件的jaxb.properties文件与编译类位于同一目录中。属性文件的内容是：

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

当我发送包含SIRFCatalog的XML文件时，所有内容都按预期运行：

curl -i -X PUT -H "Content-Type:multipart/form-data" -F catalog=@a.xml http://$OPENSIRF_IP:$OPENSIRF_PORT/sirf/container/philContainer/catalog
HTTP/1.1 100 Continue

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: application/json
Content-Length: 48
Date: Sat, 10 Sep 2016 18:30:30 GMT

{"value":"sirf/container/philContainer/catalog"}

然而，当我在JSON中发送相同的内容时（我知道它们是相同的，因为我将同一个对象编组为XML和JSON并保存到a.xml和a.json）我得到了一个HTTP 400：

curl -i -X PUT -H "Content-Type:multipart/form-data" -F catalog=@a.json http://$OPENSIRF_IP:$OPENSIRF_PORT/sirf/container/philContainer/catalog
HTTP/1.1 100 Continue

HTTP/1.1 400 Bad Request

我怀疑我的服务器实际上是使用Vanilla JAXB而不是MOXy，但不知道如何调试它！ tomcat8日志说Content not allowed in prolog：

有什么想法吗？

然而，当我在JSON中发送相同的内容时（我知道它们是相同的，因为我将同一个对象编组为XML和JSON 保存到a.xml和a.json）我得到一个HTTP 400：

我怀疑生成的json有根node（如XML中所示），因此您必须指示MOxy不使用根节点。请按照Blaise的说明检查此link和link。

更新：是的，您需要在cURL命令中指定数据类型，如下所示：

-F "catalog=@a.json;type=application/json"

Jersey无法使用MOXy解组对象（prolog中不允许使用内容）
