解组XML文件时如何忽略命名空间 [英] How to ignore namespace when unmarshalling XML file

查看：154
本文介绍了解组XML文件时如何忽略命名空间的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

当源文件的命名空间为：

when the source file have the namespace with: 

xmlns="http://schemas.alcatel.com/iptv/singtel"

错误将被提升：

Encountered an error executing step sma-updstbparams.processfile in job sma-updstbparams
org.springframework.oxm.UnmarshallingFailureException: JAXB unmarshalling exception; nested exception is javax.xml.bind.UnmarshalException
 - with linked exception:
[com.sun.istack.internal.SAXParseException2; lineNumber: 3; columnNumber: 24; unexpected element (uri:"http://schemas.alcatel.com/iptv/singtel", local:"InitializedDeviceBE"). Expected elements are <{}InitializedDeviceBE>]

    at org.springframework.batch.item.support.AbstractItemCountingItemStreamItemReader.read(AbstractItemCountingItemStreamItemReader.java:88)

但如果我删除这样的命名空间：< DevicesGetInitializedByDatesResult> 或< DevicesGetInitializedByDatesResult xmlns => ，作业将成功运行。
我该如何解决这个问题？
非常感谢

but if I remove the namespace like this:<DevicesGetInitializedByDatesResult> or <DevicesGetInitializedByDatesResult xmlns="">, the job will run successfully. how can I fix this problem? Thanks a lot

预期的xml文件：

刚拆分源文件，如下面的xml文件：

just split the source file, like the below xml file:

<?xml version="1.0" encoding="utf-8"?>
<DevicesGetInitializedByDatesResult xmlns="http://schemas.alcatel.com/iptv/singtel">
    <InitializedDeviceBE>
        <AccountExternalID>23064787</AccountExternalID>

        <IPTVDeviceID>90fa277b-cc9e-4906-81b8-43f6c5c9e312</IPTVDeviceID>
        <ManufactureName>CISCO</ManufactureName>
        <ModelNo>ISB2200</ModelNo>
        <InitializedDate>2015-09-02T16:28:38.5400000+08:00</InitializedDate>
        <SerialNo>174871919</SerialNo>
        <PreviousSerialNo/>

推荐答案

正如我遇到的问题，有两种方法可以解决，

As the problem I encountered, Two ways to fix,

一个是创建package-info.java，就像这样：所有子元素都标有命名空间[Jaxb2Marshaller]

One is create "package-info.java", just like this: All child elements are tagged with namespace [Jaxb2Marshaller]

第二种方式使用 XStreamMarshaller 代替Jaxb2Marshaller，代码是：

The second way is use the XStreamMarshaller instead of the Jaxb2Marshaller the code is:

<bean id="tradeMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
    <property name="autodetectAnnotations" value="true"/>
    <property name="aliases">
     <map>
        <entry key="InitializedDeviceBE" value="com.ncs.sma.model.SmaUpdstbparamsRecord" />
      </map>
    </property>
</bean>

第二种方式更简单，更方便，配置更少。

The second way is more simple,convenience and less configuration.
