webservice服务报错，信息如下：

javax.xml.bind.MarshalException
 - with linked exception:
[com.sun.istack.SAXException2: unable to marshal type "wsstub.sscm.importShipAdviceInfoRouteSrv.InputParameters" as an element because it is missing an @XmlRootElement annotation]

错误原因，实体类缺少注解@XmlRootElement，加上即可，如下：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "InputParameters", propOrder = {
    "inputcollection",
    "msgheader"
})
@XmlRootElement(name="InputParameters")
public class InputParameters {

}
