JAXB XJC 代码生成 - “schemaLocation"Marshaller 生成的 xml 中缺少

2022-01-09 00:00:00 xml xsd java jaxb xjc

我使用 XJC 工具为我的 XSD 模式生成 Java 类.当我使用 JAXB Marshaller 将类编组为 XML 有效负载时，我在输出 XML 中缺少schemaLocation"参数，但我在 xsd 文件中声明了此参数.如何在输出 XML 中强制执行schemaLocation"参数?

I Use XJC tool to generate Java classes for my XSD schema. When I use JAXB Marshaller to marshall classes into XML payloads, I'm missing "schemaLocation" parameter in the output XML, but I declare this parameter in xsd file. How to enforce "schemaLocation" parameter in the output XML?

下面是我用于代码生成的 xsd 架构文件的开头:

Below is the begining of my xsd schema file used for code generation:

<?xml version="1.0" encoding="UTF-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="xsdns" xmlns:messages="http://www.exampleURI.com/Schema1" xmlns:datatypes="http://www.exampleURI.com/Schema1" xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance" xsi:schemaLocation="http://www.exampleURI.com/Schema1 ./messages.xsd" targetNamespace="http://www.exampleURI.com/Schema1" elementFormDefault="unqualified" version="true">
<xs:include schemaLocation="datatypes.xsd"/>
<xs:complexType name="execute-system-command-struct">
    <xs:annotation>
        <xs:documentation>The request for system command execution.</xs:documentation>
    </xs:annotation>
    <xs:sequence/>
    <xs:attribute name="action" type="datatypes:system-action-kind-enum" use="required">
        <xs:annotation>
            <xs:documentation>The action that the Voice System has to proceed.</xs:documentation>
        </xs:annotation>
    </xs:attribute>

问候

推荐答案

试试这个:

marshaller.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "http://my.namespace my.schema.xsd");
