java - 生成的 XML 中的子元素没有父级的命名空间 - JAXB

Question

我正在使用 JAXB 生成用于 XML 编码/解码的类。问题是父级的命名空间仅适用于 XML 中的父级元素，而不适用于 JAXB 带注释的类中使用的子类。

我不确定我犯了什么错误。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 class is not in the same package. How do I include it in the Jaxb class and generate the 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。

我的架构中还缺少 targetNamespace="http://w.com/"。
