Java JAXB解组异常

在底部编辑

当前正在经历一个又一个错误。似乎我向前迈出了一步，不得不后退两步：）不幸的是，我在本地没有可以配对的人，所以我的很多调试都是通过谷歌完成的，等等

我不太熟悉jaxb，也不太熟悉使用它进行soap调用（这是我目前正在尝试的——连接到soap服务），但有人告诉我，这是我想要做的最简单的方法，我应该研究一下，因为我在项目的其余部分使用spring boot，所以我找到了一个教程（）并从那里开始

下面是我的pom的插件部分，它创建了基于wsdl的类包：

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.12.3</version>

    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>

    <configuration>
        <schemaLanguage>WSDL</schemaLanguage>
        <generatePackage>vantiveGenericWebService.wsdl</generatePackage>

        <schemas>
            <schema>
                <url>http://hostname:port/GenericWebService/ws?service=InstalledComponentService2&amp;appl=vantive&amp;wsdl</url>               
            </schema>
        </schemas>
    </configuration>
</plugin>

以及客户端配置类：

@Configuration
public class VantiveGenericWebServiceConfig {

    @Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setContextPath("vantiveGenericWebService.wsdl");
        return marshaller;
    }

    @Bean
    public VantiveGenericWebServiceClient vantiveGenericWebServiceClient(Jaxb2Marshaller marshaller) {
        VantiveGenericWebServiceClient client = new VantiveGenericWebServiceClient();
        client.setDefaultUri("http://hostname:port/GenericWebService/ws?&service=InstalledComponentService2&appl=vantive");
        client.setMarshaller(marshaller);
        client.setUnmarshaller(marshaller);

//        ClientInterceptor[] interceptors = new ClientInterceptor[] { new ClientInterceptor() {
//            @Override
//            public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {
//                return false;
//            }
//
//            @Override
//            public boolean handleResponse(MessageContext messageContext) throws WebServiceClientException {
//                return true;
//            }
//
//            @Override
//            public boolean handleFault(MessageContext messageContext) throws WebServiceClientException {
//                return true;
//            }
//
//            @Override
//            public void afterCompletion(MessageContext messageContext, Exception e) throws WebServiceClientException {
//
//            }
//        }};

//        client.setInterceptors(interceptors);
        return client;
    }
}

现在来看看错误！首先，我得到一个像这样的：

org.springframework.oxm.MarshallingFailureException: JAXB marshalling exception; nested exception is javax.xml.bind.MarshalException
 - with linked exception:
[com.sun.istack.internal.SAXException2: unable to marshal type "vantiveGenericWebService.wsdl.GetICDetailsByAssetTag" as an element because it is missing an @XmlRootElement annotation]

@XmlRootElement(name = "assetTag")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "getICDetailsByAssetTag", propOrder = {
    "assetTag"
})
public class GetICDetailsByAssetTag {

因此，我修改了GetICDetailsByAssetTag类（从wsdl生成的类）如下所示：

org.springframework.oxm.MarshallingFailureException: JAXB marshalling exception; nested exception is javax.xml.bind.MarshalException
 - with linked exception:
[com.sun.istack.internal.SAXException2: unable to marshal type "vantiveGenericWebService.wsdl.GetICDetailsByAssetTag" as an element because it is missing an @XmlRootElement annotation]

@XmlRootElement(name = "assetTag")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "getICDetailsByAssetTag", propOrder = {
    "assetTag"
})
public class GetICDetailsByAssetTag {

我不能100%确定它是正确的xml根，但是错误消失了。现在，我的第二个（也是当前）错误是：

org.springframework.oxm.UnmarshallingFailureException: JAXB unmarshalling exception; nested exception is javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are <{http://hostname/vantive/ws/InstalledComponentService2}DuplicateException>,<{http://hostname/vantive/ws/InstalledComponentService2}FunctionalException>,<{http://hostname/vantive/ws/InstalledComponentService2}GetICDetailsByAssetTagResponse>,<{http://hostname/vantive/ws/InstalledComponentService2}GetInstalledComponentDetailsByAssetTagAndStatusResponse>,<{http://hostname/vantive/ws/InstalledComponentService2}InvalidValuesException>,<{http://hostname/vantive/ws/InstalledComponentService2}SetClientDeviceXrefResponse>,<{http://hostname/vantive/ws/InstalledComponentService2}SetInstalledComponentAssetTagResponse>,<{http://hostname/vantive/ws/InstalledComponentService2}TechnicalException>,<{http://hostname/vantive/ws/InstalledComponentService2}assetTag>,<{http://hostname/vantive/ws/InstalledComponentService2}getICDetailsByAssetTag>,<{http://hostname/vantive/ws/InstalledComponentService2}getInstalledComponentDetailsByAssetTagAndStatus>,<{http://hostname/vantive/ws/InstalledComponentService2}installedComponentAssetTagDetails>,<{http://hostname/vantive/ws/InstalledComponentService2}installedComponentDetails>,<{http://hostname/vantive/ws/InstalledComponentService2}setClientDeviceXref>,<{http://com.savvis.it/vantive/ws/InstalledComponentService2}setClientDeviceXrefResult>,<{http://hostname/vantive/ws/InstalledComponentService2}setInstalledComponentAssetTag>,<{http://hostname/vantive/ws/InstalledComponentService2}setInstalledComponentAssetTagResult>

查看这篇博客文章，了解关于XmlRootElement的非常好的解释：嘿，感谢@jonckwanderkogel的链接！这是很多信息（好东西），实际上我带着更多的问题离开了，但我将把这些问题留给另一个主题：）我带走的一件很快的事情是我将XmlRootElement设置为“assetTag”实际上可能是正确的元素…基于soap请求。查看这篇博客文章，了解关于XmlRootElement的非常好的解释：嘿，谢谢@jonckwanderkogel的链接！这是很多信息（好东西），实际上我带着更多的问题离开了，但我将把这些问题留给另一个主题：）我带走的一件很快的事情是，我将XmlRootElement设置为“assetTag”实际上可能是正确的元素……基于soap请求。
