创建一个常见的xsd生成类,供其他包使用

Question

我试图使用相同的生成类,但在单独的包中.所以结构看起来应该是这样的:

com.test.common
     -commonType.java
com.test.A
     -objectA.java
com.test.B
     -objectB.java

但我一直这样:

com.test.common
     -commonType.java
com.test.A
     -objectA.java
     -commonType.java
com.test.B
     -objectB.java
     -commonType.java

我的common.xsd看起来像这样:

<?xml version="1.0"?>
<xs:schema elementFormDefault="qualified" version="1.0"
    targetNamespace="http://test.com/magic/common"
    xmlns="http://test.com/magic/common"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    jaxb:version="2.0">

    <xs:complexType name="CommonType">
        <xs:sequence>
            <xs:element name="name" type="xs:string" />
        </xs:sequence>
    </xs:complexType>

</xs:schema>

objectA.xsd看起来像

<?xml version="1.0"?>
<xs:schema elementFormDefault="qualified" version="1.0"
    targetNamespace="http://test.com/magic/objectA"
    xmlns:common="http://test.com/magic/common"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    jaxb:version="2.0">

    <xs:complexType name="ObjectA">
        <xs:sequence>
            <xs:element name="size" type="xs:string" />
            <xs:element name="commonA" type="common:CommonType" />
        </xs:sequence>
    </xs:complexType>

</xs:schema>

而objectB.xsd看起来像:

<?xml version="1.0"?>
<xs:schema elementFormDefault="qualified" version="1.0"
    targetNamespace="http://test.com/magic/objectB"
    xmlns:common="http://test.com/magic/common"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    jaxb:version="2.0">

    <xs:complexType name="ObjectB">
        <xs:sequence>
            <xs:element name="version" type="xs:string" />
            <xs:element name="commonB" type="common:CommonType" />
        </xs:sequence>
    </xs:complexType>

</xs:schema>

我有一个常见的绑定文件common.xjb,如下所示:

    <jxb:bindings schemaLocation="../xsd/common.xsd" node="/xsd:schema">
        <jxb:schemaBindings>
            <jxb:package name="com.test.common"/>
        </jxb:schemaBindings>
    </jxb:bindings>

最后我的maven工作看起来像这样:

        <plugin>
            <groupId>org.jvnet.jaxb2.maven2</groupId>
            <artifactId>maven-jaxb2-plugin</artifactId>

Answer 1

maven-jaxb2-plugin文档中有一部分专门用于单独的模式编译.但您也可以通过常用的XJC绑定实现目标.

• 不要generatePackage在插件配置中使用,请jaxb:package在绑定中使用,例如:

  <jaxb:schemaBindings>
      <jaxb:package name="generatePackage"/>
  </jaxb:schemaBindings>
  

• 使用<jaxb:class ref="com.test.common.CommonType"/>上commonType在xjb/commons.xjb.

Answer 2

您可以使用-episodeJAXB XJC中的扩展来处理此用例:

XJC调用common.xsd

xjc -d out -episode common.episode common.xsd

XJC调用objectA.xsd

从第一步生成的剧集文件实际上是一个JAXB外部绑定文件,其中包含模式类型和现有类之间的链接.这可以防止XJC重新生成这些类.

xjc -d out objectA.xsd -extension -b common.episode
