创建一个通用的 xsd 生成类以供其他包使用

问题描述

我试图在不同的包中使用相同的生成类.所以结构应该是这样的:

I am trying to use the same generated class but in separate packages. So the structure should look something like this:

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

但我一直收到这个:

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:

My common.xsd looks like this:

<?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

the objectA.xsd looks like

<?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>

和 objectB.xsd 看起来像:

And objectB.xsd looks like:

<?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>

我有一个通用的绑定文件 common.xjb，它看起来像这样:

I have a common binding file common.xjb which looks like this:

    <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:

And finally my maven job looks like this:

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

            </executions>

推荐答案

maven-jaxb2-plugin 文档中有一部分专门用于 单独的模式编译.但是您也可以使用通常的 XJC 绑定来实现您的目标.

There is a part in the maven-jaxb2-plugin documentation dedicated specifically to the separate schema compilation. But you can also achieve your goal with usual XJC bindings.

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

• Do not use generatePackage in the plugin config, use jaxb:package in bindings, ex.:

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

在 xjb/commons.xjb 上的 commonType 上使用 <jaxb:class ref="com.test.common.CommonType"/>代码>.

Use <jaxb:class ref="com.test.common.CommonType"/> on commonType in xjb/commons.xjb.
