CXF JSONProvider编组导致java.lang.ClassNotFoundException：com.sun.xml.bind.marshaller.NamespacePrefixMapper

Question

我正在尝试使用CXF设置JAX-RS服务，该服务将接受并返回json和xml 。 我也希望通过xsd通过JAXB验证请求消息。 为了实现这一点，我已经解决了几个问题，但始终有另一个问题需要克服。

所以这个问题是关于

java.lang.ClassNotFoundException: com.sun.xml.bind.marshaller.NamespacePrefixMapper

我得到的配置和异常如下所示

我的服务

@Path("incident")
public class IncidentService {

    @POST
    @Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    public Response createIncident(Incident incident,
            @HeaderParam("Accept") String acceptHeader,
            @HeaderParam("skip-creation") boolean skip) {

        String responseType = null;
        if (acceptHeader.equals(MediaType.APPLICATION_XML)) {
            responseType = MediaType.APPLICATION_XML;
        } else {
            responseType = MediaType.APPLICATION_JSON;
        }
        IncidentServiceResponse response = getResponse();
        return Response.ok(response).type(responseType).build();    
    }
}

IncidentServiceResponse

package com.ba.sysman.assyst.rest.responses;
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class IncidentServiceResponse {

    @XmlElement
    Integer ticketId;
    @XmlElement
    String errorMessage;
    @XmlTransient
    String rawResponse;
    public IncidentServiceResponse() {
        // TODO Auto-generated constructor stub
    }
    public IncidentServiceResponse(Integer id, String rawResponse) {
        this.ticketId = id;
        this.rawResponse = rawResponse;
    }
    public Integer getTicketId(){
        return ticketId;
    }
    public String getRawResponse() {
        return rawResponse;
    }
    public void setErrorMessage(String errorMessage) {
        this.errorMessage = errorMessage;
    }
    public String getErrorMessage() {
        return errorMessage;
    }
}

pacage-info.java用于IncidentServiceResponse

@XmlSchema(namespace = "http://www.ba.com/schema/BAserviceDeskAPI", elementFormDefault = XmlNsForm.QUALIFIED)
package com.ba.sysman.assyst.rest.responses;

import javax.xml.bind.annotation.XmlSchema;

在我的请求中，我正在发送一个JSON消息，该消息已被取消编组并成功通过验证，因此没有在上面包含Incident对象。 但是在响应中， IncidentServiceResponse的解组失败，但上面有例外。

我花了一整天寻找解决方案，但没有运气。 有任何想法吗？

我正在将tomcat 7.0.42与java 1.7.0_55和CXF 3.0.1一起使用。 在Java的rt.jar中， com.sun.xml.bind.marshaller.NamespacePrefixMapper不存在（这是造成异常的原因），但是com.sun.xml.internal.bind.marshaller.NamespacePrefixMapper存在。 为什么cxf没有选择此实现？

谢谢

经过一天的搜索和绝望，并发布了这个大问题后，经过5分钟，我找到了解决方案。 搞笑！

我在pom中缺少这种依赖性

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-databinding-jaxb</artifactId>
    <version>3.0.1</version>
</dependency>

不管怎么说，还是要谢谢你
