Question

我正在使用JAXB生成用于编组/解组XML的类。问题是父命名空间仅适用于XML中的父元素，而不适用于JAXB注释类中使用的子类。

我不确定我在做什么错。下面是我的xsd和xml以及类。

XSD：

package-info.java具有以下条目

@javax.xml.bind.annotation.XmlSchema(
    xmlns = {
            @javax.xml.bind.annotation.XmlNs(prefix = "ns2", 
            namespaceURI="http://walmart.com/"),
            @javax.xml.bind.annotation.XmlNs(prefix = "wmSpecs", 
            namespaceURI ="http://w.com"),
            @javax.xml.bind.annotation.XmlNs(prefix = "xsi", 
            namespaceURI = "http://www.w3.org/2001/XMLSchema-instance")
    },
    namespace = "http://w.com/",
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
    package com.w.services.item.setup.query.domain.model.v3;

Money类不在同一个包中。我如何将其包含在 Jaxb类并生成xml？

Answer 1

添加：

@javax.xml.bind.annotation.XmlSchema(
   namespace = "http://w.com/",
   elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)

到相应包的package-info.java。

确保Money位于同一个包中。

我也错过了架构中的targetNamespace="http://w.com/"。

生成的XML中的子元素没有Parent的命名空间--JAXB
