java - JAXB 中的 XML 解析问题

Question

我正在尝试从第三方 url 解析 xml 流。在我的控制台中它看起来像。

`

 <?xml version="1.0" encoding="utf-8"?>
    <ArrayOfString xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/">
      <string>CMSDocs</string>
      <string>CRMIncomingDocs</string>
      <string>CRMOutgoingDocs</string>
      <string>Customized Reports</string>
      <string>scripts</string>
      <string>Site Assets</string>
      <string>Site Pages</string>
      <string>Style Library</string>
    </ArrayOfString> 

`

我在错误之后收到错误。

但它像 XML 一样工作

`

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ArrayOfString>
    <string>Kshitij-1</string>
    <string>Kshitij-2</string>
    <string>Kshitij-3</string>
    <string>Kshitij-4</string>
    <string>Kshitij-5</string>
</ArrayOfString>

`

谢谢

您可以使用@XmlSchema 注释来指定 namespace 限定。包注释放置在一个名为 package-info 的特殊类中，该类必须与您的域类位于同一包中。以下是适用于您的用例的示例。

包信息

@XmlSchema( 
    namespace = "http://tempuri.org/", 
    elementFormDefault = XmlNsForm.QUALIFIED) 
package example;

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