UnmarshallingFailureException：JAXB解組異常； 嵌套的異常是javax.xml.bind.UnmarshalException

Question

我正在嘗試發送SOAP請求並通過WebServiceTemplate接收響應，但是我收到以下異常：

WSDL在這里 。

SEVERE: Servlet.service() for servlet [bb] in context with path [/Bb] threw 
exception [Request processing failed; nested exception is 
org.springframework.oxm.UnmarshallingFailureException: JAXB unmarshalling 
exception; nested exception is javax.xml.bind.UnmarshalException: unexpected 
element (uri:"http://ticketmaster.productserve.com/v2/soap.php", 
local:"findEventsResponse"). Expected elements are <{}findEvents>,<{}request>,
<{}sortTicket>] with root cause

請求

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso({Request.class})
public class FindEvents {
    @XmlElement
    private Request request;

           getter / setter
}


@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso({SortTicket.class})
public class Request {
    @XmlElement
    private String apiKey;
    @XmlElement
    private String country;
    @XmlElement
    private int resultsPerPage;
    @XmlElement

public class SortTicket {
    @XmlElement
    private String field;
    @XmlElement
    private String order;

           getters / setters

    private Double maxPrice;
    @XmlElement(name = "Artists")
    private Artist artist;
    @XmlElement
    private Venue venue;

     getters / setters
}


@XmlRootElement(name = "Artists")
@XmlAccessorType(XmlAccessType.FIELD)
public class Artist {

配置如下

<oxm:jaxb2-marshaller id="marshaller">
        <oxm:class-to-be-bound name="com.bb.tickets.ticketmaster.FindEvents"/>
    </oxm:jaxb2-marshaller>

    <bean id="webServiceTemplate" 
        class="org.springframework.ws.client.core.WebServiceTemplate">
        <property name="marshaller" ref="marshaller" />
        <property name="unmarshaller" ref="marshaller" />
        <property name="defaultUri"
            value="http://ticketmaster.productserve.com/v2/soap.php" />

    </bean>

發送請求和接收響應的代碼

SortTicket sortTicket = new SortTicket();
Request request = new Request();
request.setApiKey("APIKEY");
request.setCountry("UK");
FindEvents findEvents = new FindEvents();
findEvents.setRequest(request);
FindEventsResponse response = (FindEventsResponse) 
webServiceTemplate.marshalSendAndReceive(findEvents);
System.err.println("response:"+ 
response.getReturnResult().getDetails().getCurrentPage());

從堆棧跟蹤中，我了解到JAX-B收到了marshall類型的FindEventsResponse的findEventsResponse ，但它期望使用FindEvents對象。

問題出在您的spring配置中。 您只告訴Spring， FindEvents類應該綁定到編組器。 您還需要使用classesToBeBound屬性添加FindEventsResponse類：

<oxm:jaxb2-marshaller id="marshaller">
    <property name="classesToBeBound">
        <list>
            <value>com.bb.tickets.ticketmaster.FindEvents</value>
            <value>com.bb.tickets.ticketmaster.FindEventsResponse</value>
        </list>
    </property>
</oxm:jaxb2-marshaller>

您也可以使用packageToScan屬性綁定一個包，請檢查此問題 。

希望能做到。

[編輯]：如果不起作用，請嘗試：

<oxm:jaxb2-marshaller id="marshaller">
    <oxm:class-to-be-bound name="com.bb.tickets.ticketmaster.FindEvents"/>
    <oxm:class-to-be-bound name="com.bb.tickets.ticketmaster.FindEventsResponse"/>
</oxm:jaxb2-marshaller>
