從xsd文件生成一些類後，JAXB生成錯誤類

Question

，這些類發生故障。 @xmlElementRef與required =「false」一起使用，並且該屬性不被允許。 我的.xsd我使用：

和結果（部分）

package com.softm.pau.shop.xsd; 
import javax.xml.bind.JAXBElement; 
import javax.xml.bind.annotation.XmlAccessType; 
import javax.xml.bind.annotation.XmlAccessorType; 
import javax.xml.bind.annotation.XmlElementRef; 
import javax.xml.bind.annotation.XmlType; 
@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "Address", propOrder = { 
    "city", 
    "country", 
    "createAddress", 
    "name", 
    "name2", 
    "name3", 
    "name4", 
    "street", 
    "zip" 
}) 
public class Address { 

@XmlElementRef(name = "city", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> city; 
@XmlElementRef(name = "country", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> country; 
protected Object createAddress; 
@XmlElementRef(name = "name", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> name; 
@XmlElementRef(name = "name2", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> name2; 
@XmlElementRef(name = "name3", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> name3; 
@XmlElementRef(name = "name4", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> name4; 
@XmlElementRef(name = "street", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> street; 
@XmlElementRef(name = "zip", namespace = "http://shop.pau.softm.com/xsd", type = JAXBElement.class, required = false) 
protected JAXBElement<Object> zip; 

？我怎樣才能XmlElement的，而不是XmlElementRef將？我必須在xsd中更改哪些內容？ xsd是wsdl的摘錄，我想使用生成的類來調用 webservice。

OK，有些鐵道部的相關信息在這裏，不能回答我的問題...

我與STS和工作的Java6。在我的build.xml編碼

<!-- JAXB--> 
<taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask"> 
    <classpath> 
     <fileset dir="lib/ct" includes="*.jar" /> 
    </classpath> 
</taskdef> 

<target name="gen.java" description="Generates the JAXB business objects"> 
    <xjc destdir="src/gen" extension="true"> 
     <schema dir="conf/webapp/WEB-INF/schema" includes="*.xsd" /> 
     <binding dir="resources" includes="*.xjb" /> 
    </xjc> 
</target> 

我binding.xjb看起來像

<jxb:bindings version="1.0" 
xmlns:jxb="http://java.sun.com/xml/ns/jaxb" 
xmlns:s="http://www.w3.org/2001/XMLSchema" 
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" 
jxb:extensionBindingPrefixes="xjc"> 

<jxb:bindings schemaLocation="../conf/webapp/WEB-INF/schema/wsinapa.xsd" node="/s:schema"> 
    <jxb:bindings node="/s:schema/s:element[@name='AccountStatus']"> 
     <jxb:class name="AccountStatusRequest"/> 
    </jxb:bindings> 
</jxb:bindings> 

在src目錄

是2的.xsd應該編譯。其中一個編譯時沒有 錯誤，其他沒有。兩者都從wsdl文件中提取。

Answer 1

你JAXB (JSR-222)實現不產生錯誤的類。 required屬性已添加到JAXB 2.2中的@XmlElementRef註釋中。

• http://docs.oracle.com/javase/7/docs/api/javax/xml/bind/annotation/XmlElementRef.html#required()

最有可能你已經生成Java SE 7中（包括JAXB 2.2）JAXB類，並試圖在Java SE 6中（包括JAXB 2.1），然後運行。使用JAXB 2.2實現，您可以使用-target標誌創建JAXB 2.1（或JAXB 2.0）兼容代碼。

xjc -target 2.1 schema.xsd 

Answer 2

我覺得它在xsd中沒什麼改變。嘗試創建一個綁定文件，如simple-binding.xjb。

<jaxb:bindings version="2.1" 
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" 
xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <jaxb:globalBindings generateElementProperty="false"/> 
</jaxb:bindings> 

然後在從xsd生成java類時使用此命令。我想你是wsimport，伴隨着jdk來生成源代碼。

wsimport -b simple-binding.xjb 

所以，如果你正在使用the maven-jaxb2-plugin運行XJC你不會得到標籤XmlElementRef

Answer 3

，你可能會碰到同樣的問題。我通過將<specVersion>的2.1加到我的pom.xml來修復它。如下：

<plugin> 
    <groupId>org.jvnet.jaxb2.maven2</groupId> 
    <artifactId>maven-jaxb2-plugin</artifactId> 
    <executions> 
    <execution> 
     ... 
     <configuration> 
     ... 
     <specVersion>2.1</specVersion> 
     ... 
     </configuration> 
    </execution> 
    </executions> 
</plugin>
