Java-JAXB中的Xml解析问题

2023-07-17 10:09:46

我正在尝试从第三方URL解析xml流.在我的控制台中看起来像.

 <?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>

而且我得到错误之后的错误.

但是它正在使用XML

<?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

解决方法:

您可以使用@XmlSchema批注指定名称空间限定.程序包批注放置在一个名为package-info的特殊类上,该类必须与您的域类位于同一程序包中.下面是一个适用于您的用例的示例.

包装信息

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

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