Question

m trying using the JAXB annotations to send and xml file but I saw that the nodes has this format:

<:subject xmlns="http://www..." xmlns:atom="http://www.w3.org/2005/atom">
 <:data>maths<:data>
</:subject>

而不是:

<subject xmlns="http://www..." xmlns:atom="http://www.w3.org/2005/atom">
 <data>maths<data>
</subject>

I can t understand why this happens. From where insert the : symbol and why? T

My model has this form:


@XmlRootElement(name="subject")
@XmlAccessorType(XmlAccessType.FIELD)
public class Registration {

   private String data;

    get/set
}

我的包裹——Info.java:

  @javax.xml.bind.annotation.XmlSchema (
   namespace="http://www..",
   elementFormDefault=XmlNsForm.QUALIFIED,
xmlns = { 
  @javax.xml.bind.annotation.XmlNs( prefix=" ", namespaceURI="http://www..."),
  @javax.xml.bind.annotation.XmlNs( prefix="atom" ,namespaceURI="http://www.w3.org/2005/atom")
})

 package mypackage.affil;

 import javax.xml.bind.annotation.XmlNsForm;

我认为:

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
 <%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
 <%@ page language="java" contentType="text/html"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"    "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
 <meta http-equiv="Content-Type" content="text/html">
<title>Insert title here</title>
</head>
<body>

<h1>Create New Person</h1>

<c:url var="takeinto" value="/takedata" />
<form:form modelAttribute="takedataAttribute" method="POST" action="${takeinto}">
<table>
    <tr>
        <td><form:label path="data">Affiliation</form:label></td>
        <td><form:input path="data"/></td>
    </tr>

谁能告诉我,文号是:出现在什么?

你们在那里触发了奇怪的 b! 我的猜测是,问题在于此(我删除了 Java名称,你可以通过在<条码>后填入右栏“进口<>/条码>声明”来填写这些名称:

@XmlSchema (
    namespace="http://www..",
    elementFormDefault=XmlNsForm.QUALIFIED,
    xmlns = { 
        @XmlNs( prefix=" ", namespaceURI="http://www..."),
        @XmlNs( prefix="atom" ,namespaceURI="http://www.w3.org/2005/atom")
})

I m guessing that it is a combination of using a single empty string for the prefix and QUALIFIED for elementFormDefault. Try this instead:

@XmlSchema(
    namespace="http://www..",
    elementFormDefault=XmlNsForm.UNQUALIFIED,
    xmlns = { 
        @XmlNs(prefix="atom", namespaceURI="http://www.w3.org/2005/atom")
})

That is, UNQUALIFIED and only providing xmlns for the parts that you want qualified. It s possible that you ll need to specify the namespace on @XmlElement tags throughout (the documentation is somewhat unclear) so I also recommend refactoring that out into a constant in an interface; that makes things clearer too.
