Question

当JABX unmarshaller尝试解组xml时，我遇到以下错误

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。]

当我查看从服务器返回的xml时，它是以下内容：

<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？

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

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;

将架构位置添加到JAXB unmarshaller
