JAXB:所有元素都需要命名空间前缀

I am Using Spring WebServiceTemplate to make webservice call which uses JAXB to generate request XML. My requirement needs all the elements (including root) to have a namespace prefix (there is only a single namespace) in the SOAP request.

我正在使用Spring WebServiceTemplate进行webservice调用，该调用使用JAXB生成请求XML。我的需求需要所有元素(包括根)在SOAP请求中具有名称空间前缀(只有一个名称空间)。

Ex :

例:

<ns1:Login xmlns:ns1="www.example.com/a">
    <ns1:username>abc</ns1:username>
    <ns1:password>abc</ns1:password>
</ns1:Login>

But i am getting

但我得到

<Login xmlns="www.example.com/a">
    <username>abc<username>
    <password>abc<password>
</Login>

xsd :

xsd:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="www.example.com/a"   xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ilreq="www.example.com/a" elementFormDefault="qualified" attributeFormDefault="unqualified">

<xs:complexType name="Login">
    <xs:sequence>
        <xs:element name="username" type="xs:string"/>
        <xs:element name="password" type="xs:string"/>
    </xs:sequence>
</xs:complexType>

Generated Java Class from XSD

从XSD生成Java类

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Login", propOrder = {
    "username",
    "password"
})

@XmlRootElement
public class Login {

@XmlElement(required = true)
protected String username;
@XmlElement(required = true)
protected String password;
......
}

package-info.java

@javax.xml.bind.annotation.XmlSchema(
    namespace = "www.example.com/a",
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package authenticator.beans.login;

Want to know how to generate the request XML with Namespace prefix to all elements including root.

想知道如何为包括root在内的所有元素生成带有名称空间前缀的请求XML。

Solved by adding

解决了通过添加

@XmlSchema(
    namespace = "http://www.example.com/a",
    elementFormDefault = XmlNsForm.QUALIFIED,
    xmlns = {
        @XmlNs(prefix="ns1", namespaceURI="http://www.example.com/a")
    }
)  

package authenticator.beans.login;
import javax.xml.bind.annotation.*;

in package-info.java

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

您是否尝试将名称空间声明设置为这样的成员变量?:

@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;

@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.

对于我们的项目，它解决了命名空间问题。我们还必须创建名称空间前缀映射器。

#3

Another way is to tell the marshaller to always use a certain prefix

另一种方法是告诉编组器总是使用某个前缀

marshaller.setProperty("com.sun.xml.bind.namespacePrefixMapper", new NamespacePrefixMapper() {
             @Override
            public String getPreferredPrefix(String arg0, String arg1, boolean arg2) {
                return "ns1";
            }
        });'

#4

To specify more than one namespace to provide prefixes, use something like:

要指定多个名称空间以提供前缀，请使用以下内容:

@javax.xml.bind.annotation.XmlSchema(
    namespace = "urn:oecd:ties:cbc:v1", 
    elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
    xmlns ={@XmlNs(prefix="cbc", namespaceURI="urn:oecd:ties:cbc:v1"), 
            @XmlNs(prefix="iso", namespaceURI="urn:oecd:ties:isocbctypes:v1"),
            @XmlNs(prefix="stf", namespaceURI="urn:oecd:ties:stf:v4")})

... in package-info.java

marshaller.setProperty only works on the JAX-B marshaller from Sun. The question was regarding the JAX-B marshaller from SpringSource, which does not support setProperty.

信号员。setProperty仅在Sun的JAX-B封送器上工作。问题是关于来自SpringSource的JAX-B marshaller，它不支持setProperty。

Was facing this issue, Solved by adding package-info in my package

在我的包中添加包信息解决了这个问题吗

and the following code in it:

其中的代码如下:

@XmlSchema(
    namespace = "http://www.w3schools.com/xml/",
    elementFormDefault = XmlNsForm.QUALIFIED,
    xmlns = {
        @XmlNs(prefix="", namespaceURI="http://www.w3schools.com/xml/")
    }
)  
package com.gateway.ws.outbound.bean;

import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

 For same query i want to set the xmlns for each element and the 
 prefix should not be there, e.g.
<Login xmlns="www.example.com/a">
<username xmlns="http://sample.com/user">abc<username>
<password xmlns="http://sample.com/user">abc<password>
</Login>
Please suggest....
