你可以在这个网站上找到很多像这样的问题,但没有一个问题解决了我的问题.

Unmarshal代码:

    public LookupInstances unmarshallXmlRequest(String xmlReq)
    {
        LookupInstances instances = null;
           try {
            JAXBContext jc = JAXBContext.newInstance( LookupInstances.class );
               Unmarshaller u = jc.createUnmarshaller();
               StringBuffer xmlStr = new StringBuffer( xmlReq );
               StringReader strReader = new StringReader( xmlStr.toString() );
               StreamSource strSource = new StreamSource(strReader);
               Object o = u.unmarshal( strSource );
               instances = (LookupInstances)o;
        } catch (JAXBException e) {

            e.printStackTrace();
        }
        return instances;
    }

我收到了这个错误:

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>

请帮忙.

以下是一些应该有用的信息:

XML

下面是XML的一部分.有一点需要注意的是xmlns属性.这是一个特殊属性,指的是XML文档中的名称空间限定.

下面是另一个具有相同命名空间限定的XML版本:

删除xmlns属性时,将删除命名空间限定.以下文件不等同于上述两个.

你的错误

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>

此错误表示您尚未正确映射命名空间限定.

在JAXB中映射Namesapce资格

JAXB中的命名空间限定是使用包级别@XmlSchema注释完成的.包级别注释进入package-info.java.以下是此课程的完整来源.如果您已有package-info.java源文件,请确保正在编译并与其余类一起打包.

@XmlSchema( 
    namespace = "http://www.pqr.com/awd/rest/v1", 
    elementFormDefault = XmlNsForm.QUALIFIED) 
package your_package;

import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

XML Schema

如果要从XML Schema生成模型,请确保在此处正确定义此命名空间限定.它看起来像:

更改

@XmlRootElement(name = "lookupInstances")

至

@XmlRootElement( namespace = "http://www.pqr.com/awd/rest/v1", name = "lookupInstances")
