Question

我的目标是从几个xsd架构生成Java类。

我有四个XSD文件，它们都有一个空命名空间，我无法更改它们：

SimpleTypeDefinitions（所有其他人引用的misc类型）
标题（由以下两个xsds引用）
SingleRequest
BatchRequest

SingleRequest和BatchRequest非常相似，它们都包含具有相同名称的元素。有一个带有单个XMLAny元素的通用Web服务。这可以（当前）包含SingleRequest或BatchRequest。这种设计不在我的掌控之中，绝对不能改变。

我想从xsds生成我的Java类，它对SingleRequest工作正常。我必须在单个webservice-method中包含带有XMLSeeAlso注释的生成类。现在我必须添加BatchRequest，我遇到了麻烦，因为它们存在冲突。

我首选的解决方案是将所有内容放在一个项目中（和一个pom.xml），以及来自不同包中生成的不同xsds的java类。在这一点上，我对任何解决方案都很满意。

我尝试了很多我在网上找到的不同解决方案（其中有几个在SO上），但是没有一个解决方案，据我所知，在每个解决方案中，XSD都位于不同的命名空间中。其中我试过：

为每个xsd文件执行jaxb2-maven-plugin的几次
剧集有多种方式（直接在maven-plugin执行中，在执行中使用命令行参数，引用生成的.episode文件）
在jaxb绑定文件中重命名冲突的类名，我仍然得到＆＃34; ...已定义＆＃34;来自maven的错误。

我使用JAXB 2.2.7和maven-jaxb2-plugin 0.9.0。

有什么想法吗？

EDIT1 2014-06-08：我创建了示例XSD文件来重现我的问题，我还包括一个示例pom。使用包含的pom，Java类在不同的包中生成，但每个包都有一个类＆＃34; Header.java＆＃34;。这会在运行时导致以下错误（当我尝试调用web服务时）：

javax.xml.ws.WebServiceException：无法创建JAXBContext导致 by：java.security.PrivilegedActionException： com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException：5 IllegalAnnotationExceptions的计数两个类具有相同的XML 输入姓名＆＃34; {myService} myElement＆＃34;。使用@ XmlType.name和 @ XmlType.namespace为它们分配不同的名称。

Answer 1

我有一个解决方案，但你的xsd并不好。

BatchRequest.xsd中的RequestContentType和SingleRequest.xsd中的RequestContentType是相同的类型。

如果你改变这种方式，一切正常......

Header.xsd

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

  <xs:complexType name="HeaderType">
    <xs:sequence>
      <xs:element minOccurs="1" maxOccurs="1" name="TimeStamp" type="xs:dateTime" nillable="false"/>
      <xs:element minOccurs="1" maxOccurs="1" name="TimeOut" type="xs:long" default="0" nillable="true"/>
    </xs:sequence>
  </xs:complexType>

</xs:schema>

                    </xs:sequence>
                </xs:complexType>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:element>

<xs:complexType name="RequestContentType">
    <xs:sequence>
        <xs:element minOccurs="1" maxOccurs="1" nillable="false" name="RequestContentId" type="xs:string" />
        <xs:element minOccurs="1" maxOccurs="1" nillable="false" name="batchSpecificContent" type="xs:string" />
