SOAP接口XML响应XSD验证报错：Premature end of file

问题描述

对SOAP接口返回的XML响应进行XSD验证时，触发org.xml.sax.SAXParseException错误，错误信息显示“Premature end of file”，关联的systemId为http://schemas.xmlsoap.org/soap/envelope/。已将该链接对应的XSD文件下载到项目src/main/resources目录，但问题仍未解决。

测试代码

File file = new File("./SoapRequests/add.xml");
if(file.exists())
{
    System.out.println(">>>>  File Exists  <<<<");
}

FileInputStream fileinputstream = new FileInputStream(file);
String requestBody = IOUtils.toString(fileinputstream, "UTF-8");

baseURI = "http://www.dneonline.com";

given().
    contentType("text/xml").
    accept(ContentType.XML).
    body(requestBody).

    post("/calculator.asmx").
then().
    statusCode(200).
    log().all().
and().
    body("//*:AddResult.text()", equalTo("5")).
and().
    assertThat().body(matchesXsdInClasspath("Calculator.xsd"));

请求XML文件

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Add xmlns="http://tempuri.org/">
      <intA>2</intA>
      <intB>3</intB>
    </Add>
  </soap:Body>
</soap:Envelope>

使用的XSD文件

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://tempuri.org/" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:import namespace="http://schemas.xmlsoap.org/soap/envelope/"   
           schemaLocation="http://schemas.xmlsoap.org/soap/envelope/"/>
  <xs:element name="AddResponse">
    <xs:complexType>
      <xs:sequence>
        <xs:element type="xs:byte" name="AddResult"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

解决方案

错误原因

XSD文件中<xs:import>的schemaLocation仍指向远程地址，解析器尝试从该地址下载SOAP信封XSD时，因网络或访问限制导致下载失败，返回空内容，触发“Premature end of file”错误。即使已下载本地XSD文件，解析器也未使用。

修复步骤

修改XSD的import路径：将Calculator.xsd中的<xs:import>语句的schemaLocation改为本地XSD文件名。假设下载的SOAP信封XSD文件名为soap-envelope.xsd，且与Calculator.xsd同处于src/main/resources目录，修改后代码如下：

<xs:import namespace="http://schemas.xmlsoap.org/soap/envelope/" schemaLocation="soap-envelope.xsd"/>

确认本地XSD位置：确保soap-envelope.xsd确实放在src/main/resources目录下，编译后能被类路径加载。
重新运行测试：此时解析器会从本地类路径加载导入的XSD文件，无需访问远程地址，即可完成XML响应的验证。
