Question

我从Web服务调用中得到了以下repsonse，我尝试使用JAXB解组它以将其映射到java类。这样做时我得到了解组异常。

<?xml version="1.0" encoding="UTF-8"?>
<ns0:QueryByLNResponse xmlns:ns0="UIS_CTMPeople_WS" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <ns0:getListValues>
        <ns0:First_Name>Pradeep</ns0:First_Name>
        <ns0:Internet_E-mail/>
        <ns0:ManagersName/>
        <ns0:Person_ID>PPL1</ns0:Person_ID>
        <ns0:Last_Name>Srinivasa Reddy</ns0:Last_Name>
        <ns0:Full_Name>Pradeep M Srinivasa Reddy</ns0:Full_Name>
    </ns0:getListValues>
    <ns0:getListValues>
        <ns0:First_Name>Geeth </ns0:First_Name>
        <ns0:Internet_E-mail>bas@yahoo.com</ns0:Internet_E-mail>
        <ns0:ManagersName/>
        <ns0:Person_ID>PPL2</ns0:Person_ID>
        <ns0:Last_Name>Srinivasan</ns0:Last_Name>
        <ns0:Full_Name>Geeth  Srinivasan</ns0:Full_Name>
    </ns0:getListValues>
</ns0:QueryByLNResponse>

我尝试使用

解组上面的代码

public static Object xmlToObject(String xml, Class... objClass) throws Exception {
    JAXBContext jc = JAXBContext.newInstance(objClass);
    final Unmarshaller unmarshaller = jc.createUnmarshaller();
    return unmarshaller.unmarshal(new StringReader(xml.toString()));
}

抛出以下错误

javax.xml.bind.UnmarshalException: unexpected element (uri:"UIS_CTMPeople_WS", local:"QueryByLNeResponse"). Expected elements are (none)

如何使用JAXB（xml to object）解组它。

Answer 1

以下是一些应该有用的项目：

<强> NAMESPACES

您应该使用@XmlSchema类上的package-info注释来指定命名空间限定。下面是一个示例，您需要更改包名称以匹配您的模型。

的 package-info.java 的

@XmlSchema( namespace = "UIS_CTMPeople_WS", elementFormDefault = XmlNsForm.QUALIFIED) package example; import javax.xml.bind.annotation.XmlNsForm; import javax.xml.bind.annotation.XmlSchema;

ROOT ELEMENTS

您似乎没有使用@XmlRootElement（或@XmlElementDecl）映射任何类。我希望你有类似的东西：

的 QueryByLNResponse 的

package example; @XmlRootElement(name="QueryByLNResponse") public class QueryByLNResponse { }

或者，您可以使用一个带有Class参数的unmarshal方法指定要解组的类：

return unmarshaller.unmarshal(xml, QueryByLNResponse.class)

<强>性能

在同一代码中，每次执行解组时都会创建一个新的JAXBContext。 JAXBContext是一个线程安全的对象，可以创建一次并重用以提高性能。

XML（带命名空间）到Object解组
