我已经通过 wadl2java maven 插件从 wadl 文件生成了 java 源代码，并希望通过 Springboot jersey 创建 REST 服务。它到达服务但低于 Excetiption ：

`Can not construct instance of javax.xml.bind.JAXBElement: no suitable constructor found, can not deserialize from Object value (missing default constructor or creator, or perhaps need to add/enable type information?) at [Source: org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream@198d51da; line: 5, column: 33]

我的服务端点是这样的：

@Path("getdetails/")
public class GetdetailsResource {
    
    @POST
    @Consumes({"application/xml", "application/json" })
    @Produces({"application/xml", "application/json" })
    public Response GETDETAILS(InputParameters parameters) {
        '''''
        System.out.println(parameters);
....
        return null;
    }

}

REST 调用在解组创建具有 JAXBElement jaxbElement 的 InputParameters 时引发异常；

不知何故，即使使用此处提到的 ObjectMapper，JaxbElement 也永远不会被实例化

InputParameters 类如下：

XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "carray"
})
@XmlRootElement(name = "InputParameters")
public class InputParameters {
    public InputParameters() {
        // TODO Auto-generated constructor stub
        System.out.println();
    }

    @XmlElementRef(name = "P_CONTRACT_ARRAY", namespace = "http://xmlns.oracle.com/apps/getdetails/", type = JAXBElement.class, required = false)
    protected JAXBElement<APPAXX> carray;


    public JAXBElement<APPAXX> getcarray() {
        return carray;
    }

    public void setcarray(JAXBElement<APPAXX> value) {
        this.carray = value;
    }

}
