Please help.
请帮忙。
回答by Magnilex
It seems that the class created by JAXB does not contain the namespace information:
JAXB创建的类似乎不包含命名空间信息：
@XmlType(name = "", propOrder = {
"lookupParameters"
})
I suspect that it causes this error, simply because it expects no namespace:
我怀疑它会导致此错误，仅仅是因为它不需要命名空间：
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
javax.xml.bind.UnmarshalException：意外元素（uri：“ http://www.pqr.com/awd/rest/v1”，本地：“lookupInstances”）。预期元素为 <{}lookupInstances>
I am not sure why the generated class lacks this information, but I would start with adding it manually to verify that this is the problem:
我不确定为什么生成的类缺少此信息，但我会先手动添加它以验证这是问题所在：
@XmlType(name = "", namespace= "http://www.pqr.com/awd/rest/v1", propOrder = {
"lookupParameters"
})

I have changed the jaxb class by changing the xsd and it is working now.
我通过更改 xsd 更改了 jaxb 类，现在它正在工作。

Below is some information that should help:
以下是一些应该有帮助的信息：
XML
XML
Below is a portion of your XML. One thing to note is the xmlnsattribute. This is a special attribute and refers to namespace qualification within the XML document.
下面是您的 XML 的一部分。需要注意的一件事是xmlns属性。这是一个特殊的属性，指的是 XML 文档中的命名空间限定。
<lookupInstances xmlns='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<lookupParameters/>
</lookupInstances>
Below is another version of the XML with the same namespace qualification:
下面是具有相同命名空间限定的 XML 的另一个版本：
<abc:lookupInstances xmlns:abc='http://www.pqr.com/awd/rest/v1' name='LKIMGR'>
<abc:lookupParameters/>
</abc:lookupInstances>
When you remove the xmlnsattribute the namespace qualification is removed. The document below is not equivalent to the two above.
当您删除xmlns属性时，命名空间限定被删除。下面的文档不等同于上面的两个。
<lookupInstances name='LKIMGR'>
<lookupParameters/>
</lookupInstances>
Your Error
你的错误
javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.pqr.com/awd/rest/v1", local:"lookupInstances"). Expected elements are <{}lookupInstances>
This error indicates that you have not mapped the namespace qualification correctly.
此错误表明您没有正确映射命名空间限定。
Mapping the Namesapce Qualification in JAXB
在 JAXB 中映射 Namesapce Qualification
Namespace qualification in JAXB is done using the package level @XmlSchemaannotation. Package level annotations go in package-info.java. Below is the complete source for this class. If you already have a package-info.javasource file ensure it is being compiled and packaged with the rest of your classes.
JAXB 中的命名空间限定是使用包级别@XmlSchema注释完成的。包级注释进入package-info.java. 下面是这个类的完整源代码。如果您已经有一个package-info.java源文件，请确保它正在与您的其余类一起编译和打包。
@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
XML 架构
If you are generating your model from an XML Schema make sure this namespace qualification is properly define there. It will look like:
如果您从 XML 模式生成模型，请确保在那里正确定义了此命名空间限定。它看起来像：
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.pqr.com/awd/rest/v1"
xmlns="http://www.pqr.com/awd/rest/v1"
elementFormDefault="qualified">
</xs:schema>
回答by Satya.pydikondala
First of all you have to check the input XML file. Make sure the input XML should have the same root element as your XSD file(Which you have used to create the JAXb classes) So please try below XML, It will work fine :)
首先，您必须检查输入的 XML 文件。确保输入的 XML 应该与您的 XSD 文件具有相同的根元素（您用来创建 JAXb 类）所以请尝试下面的 XML，它会正常工作:)
<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<lookupInstances name='LKIMGR'>
<lookupParameters>
<lookupParameter name='businessArea'>PQAA</lookupParameter>
<lookupParameter name='MEMBERNUMBER'>ANTHONY1900</lookupParameter>
</lookupParameters>
</lookupInstances>

回答by ClickBright
@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;
This part is very important for JAXB generated classes, especially elementFormDefault = XmlNsForm.QUALIFIEDwill not automatically be added by the JAXB.
这部分对于 JAXB 生成的类非常重要，尤其是elementFormDefault = XmlNsForm.QUALIFIED不会被 JAXB 自动添加。
