Question

我写了Office.xsd

<?xml version="1.0" encoding="windows-1252" ?>

<xsd:element name="name" type="xsd:string" />

<xsd:complexType name="Employee">
    <xsd:sequence>
        <xsd:element name="entry_time" type="xsd:decimal"
            minOccurs="0" />
        <xsd:element name="exit_time" type="xsd:decimal"
            minOccurs="0" />
    </xsd:sequence>
</xsd:complexType>

 <xsd:complexType name="Furniture">
    <xsd:sequence>
        <xsd:element name="name" type="xsd:string"
            minOccurs="0" />
        <xsd:element name="quantity" type="xsd:int"
            minOccurs="0" />
    </xsd:sequence>
</xsd:complexType>

<xsd:complexType name="Office">
    <xsd:sequence>
        <xsd:element name="name" type="xsd:string" minOccurs="0" />
        <xsd:element name="address" type="xsd:string" minOccurs="0" />
        <xsd:element name="employee" type="Employee"
            minOccurs="0" />
        <xsd:element name="furniture" type="Furniture"
            minOccurs="0" />
    </xsd:sequence>
</xsd:complexType>

我正在创建另一个Institute.xsd，其中包含Office.xsd，如下所示

<xsd:include schemaLocation="Office.xsd" />

<xsd:complexType name="Institute">
    <xsd:sequence>
        <xsd:element name="id" type="xsd:in" minOccurs="1" />
        <xsd:element name="name" type="xsd:string" minOccurs="1" />
        <xsd:element name="employee" type="Employee"
            minOccurs="0" />
        <xsd:element name="furniture" type="Furniture"
            minOccurs="0" />
    </xsd:sequence>
</xsd:complexType>

我正在使用maven-jaxb2-plugin插件..这是我的插件

我在两个包中都得到了Employee.java, Furniture.Java and Office.java （com.nuovo.institute.model和com.nuovo.employee.model）。不仅在Institute.xsd中，我必须在Employee中仅使用type作为xsd，而在某些XSDs中我必须仅使用Furniture作为type Employee.java如何确保这些类在其他包中不重复，以及如何使这些生成的类（Furniture.java，Office.java和toto）与其他类相同

Answer 1

为了避免使用maven-jaxb2-plugin重复的类，您必须使用modular - aka episodic - schema compilation，即使用剧集和XML目录referencing the XSD file(s) from Maven artifact resources。但是，它known issue不适用于架构include，而只适用于架构import。因此，您可以在include中将import更改为Institude.xsd，或使用known issue页面上提到的两个选项之一：

手动编写META-INF / sub-jaxb.episode文件。

编写您自己的XJC插件以生成此文件而不使用map =“false”。这并不难，请参阅com.sun.tools.xjc.addon.episode.PluginImpl。

另外请确保升级maven-jaxb2-plugin和jaxb2-basics的版本，它们已经很老了。

如何在所有包中创建通用xsd生成的类
