从定义 SOAP 消息的 XSD 生成 Java 源

Question

我有一个为远程设备定义 SOAP 消息的 XSD。我想使用这个 XSD 并从中生成 Java 源代码来创建这些消息。 XSD 中的一条消息的示例如下：

<xs:element name="get-ethernet-stats">
    <xs:annotation>
        <xs:documentation>Ethernet stats information</xs:documentation>
    </xs:annotation>
    <xs:complexType>
        <xs:sequence>
            <xs:element name="mode" type="response-mode"/>
        </xs:sequence>
    </xs:complexType>
</xs:element>
<xs:element name="get-ethernet-stats-resp">
    <xs:complexType>
        <xs:annotation>
            <xs:documentation>Ethernet Stats</xs:documentation>
        </xs:annotation>
        <xs:sequence>
            <xs:element ref="status"/>
            <xs:element name="result" minOccurs="0">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="rx" type="xs:int"/>
                        <xs:element name="tx" type="xs:int"/>
                        <xs:element name="drops" type="xs:int"/>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:element>

关于如何做到这一点的任何建议？我查看了 JAXB，但没有原始源文件，当我运行“xjc file.xsd”来获取源文件时，这里是输出的一部分：

Answer 1

我建议你看看jaxws-rt-2.1.4.jar。这允许通过两种方式提供要在 SOAP 消息中发送的 XML：
(1) 只提供正文内容；该代码负责根据检索到的 wsdl 添加 Envelope/Header/Body 以及命名空间
(2) 提供完整的信封，加上命名空间

那么就不需要生成代码了。

例如见jaxws-guide.html
