无法使用 JAXB 解组收到的请求

Question

我定义了所有必需的元素，但代码无法解析服务器响应。我将 @XmlSeeAlso({ Artist.class, Venue.class }) 更改为 @XmlSeeAlso({Venue.class }) 但它没有帮助。

我还添加了一个 package-info.java 文件。

@XmlSchema(
    namespace = "http://ticketmaster.productserve.com/v2/soap.php",
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED
)
package com.myproject.tickets.ticketmaster;

import javax.xml.bind.annotation.*;

错误

org.springframework.http.converter.HttpMessageNotReadableException: Could not 
unmarshal to [class com.myproject.tickets.ticketmaster.Data]: unexpected 
element (uri:"", local:"data"). Expected elements are 
 <{http://ticketmaster.productserve.com/v2/soap.php}artist>, 
 <{http://ticketmaster.productserve.com/v2/soap.php}data>,
 <{http://ticketmaster.productserve.com/v2/soap.php}details>,
 <{http://ticketmaster.productserve.com/v2/soap.php}results>,
 <{http://ticketmaster.productserve.com/v2/soap.php}venue>; nested exception 
  is javax.xml.bind.UnmarshalException: unexpected element (uri:"", 
  local:"data"). Expected elements are 
  <{http://ticketmaster.productserve.com/v2/soap.php}artist>,
  <{http://ticketmaster.productserve.com/v2/soap.php}data>,
  <{http://ticketmaster.productserve.com/v2/soap.php}details>,
  <{http://ticketmaster.productserve.com/v2/soap.php}results>,
  <{http://ticketmaster.productserve.com/v2/soap.php}venue>

Answer 1

你的问题是你的解组器需要一个有命名空间的元素，而你的 XML 没有。

为了解决你的问题，要么：

在您的 XML 中放置一个命名空间（根元素中的 xmlns="http://ticketmaster.productserve.com/v2/soap.php" 属性）
从您的@XmlSchema 注释中删除名称空间属性
