将架构位置添加到JAXB unmarshaller [英] Add schema location to JAXB unmarshaller

问题描述

当JABX unmarshaller尝试解组xml时，我遇到以下错误

I am facing the below error when JABX unmarshaller tries to unmarshall the xml

线程main中的异常javax.xml.bind.UnmarshalException
- 链接异常：
[org.xml.sax.SAXParseException; lineNumber：1; columnNumber：456;与元素类型customerProductStatus关联的属性xsi：nil的前缀xsi未绑定。]

Exception in thread "main" javax.xml.bind.UnmarshalException - with linked exception: [org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 456; The prefix "xsi" for attribute "xsi:nil" associated with an element type "customerProductStatus" is not bound.]

当我查看从中返回的xml时服务器，如下所示：

When I looked at the xml being returned from the server , it is the below :

<customerProductStatus xsi:nil = "true"></customerProductStatus>

我没有在任何父标签中看到xsi定义。是否可以在不更改任何绑定的情况下将schemaLocation添加到unmarshaller？

I don't see xsi defined in any of the parent tags. Is it possible to add the schemaLocation to unmarshaller without changing any of the bindings?

JAXBContext jaxbContext1 = JAXBContext.newInstance(Request.class);
Unmarshaller jaxbUnMarshaller1 = jaxbContext1.createUnmarshaller();
Request request = (Request)jaxbUnMarshaller1.unmarshal(receiveData.getBinaryStream());

推荐答案

您可以添加：

//Gets schema
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = schemaFactory.newSchema(xmlSchema);

JAXBContext jaxbContext1= JAXBContext.newInstance(Request.class);
Unmarshaller jaxbUnMarshaller1 = jaxbContext1.createUnmarshaller();

//Sets schema with unmarshaller
jaxbUnMarshaller1 .setSchema(schema);

Request request = (Request)jaxbUnMarshaller1.unmarshal(receiveData.getBinaryStream());

所需的套餐是：

import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
