java - 为 http ://schemas. opengis.net/wfs/1.1.0/wfs.xsd 生成 JAXB 类

Question

我正在尝试使用 JAXB 为该模式生成类:http://schemas.opengis.net/wfs/1.1.0/wfs.xsd

我将该模式下载到本地文件，现在我正在尝试生成 JAXB 类。首先我得到这个错误:

[ERROR] Property "Title" is already defined. Use <jaxb:property> to resolve this conflict.
  line 261 of http://www.w3.org/1999/xlink.xsd

谷歌搜索后，我发现我需要使用绑定(bind)文件:

<jxb:bindings version="2.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <jxb:bindings schemaLocation="http://www.w3.org/1999/xlink.xsd"
        node="/xs:schema">

        <jxb:bindings node="//xs:attributeGroup[@name='locatorAttrs']">
            <jxb:bindings node=".//xs:attribute[@ref='xlink:title']">
                <jxb:property name="title1" />
            </jxb:bindings>
        </jxb:bindings>

        <jxb:bindings node="//xs:attributeGroup[@name='arcAttrs']">
            <jxb:bindings node=".//xs:attribute[@ref='xlink:title']">
                <jxb:property name="title2" />
            </jxb:bindings>
        </jxb:bindings>

    </jxb:bindings>

    <jxb:bindings
        schemaLocation="http://schemas.opengis.net/gml/3.1.1/base/geometryPrimitives.xsd"
        node="/xs:schema">
        <jxb:bindings node="//xs:element[@name='_Solid']">
            <jxb:factoryMethod name="gmlAbstractSolidElementFactory" />
        </jxb:bindings>
    </jxb:bindings>

</jxb:bindings>

但是当我使用那个绑定(bind)文件时，我遇到了很多其他错误:

我有点惊讶，只是因为这看起来像是其他人会为其生成 JAXB 类的模式，但谷歌似乎没有发现任何问题。我以前使用过 JAXB，但这似乎比我过去看到的更复杂。

是否有我需要用于该模式的特定绑定(bind)文件，或者某些特定的 JAXB 设置？

Answer 1

免责声明:我是 ogc-schemas 的首席开发人员编译几乎所有 OGC 模式的项目，包括 WFS 1.1.0 .

OGC Schemas 的编译问题很大。您需要大量绑定(bind)、定制，有时还需要补丁。所以我的建议是只使用 ogc-schemas 提供的已经编译的 schmeas。项目。得到 this artifact用于编译的 WFS 1.1.0 架构。

对于 WFS 1.1.0，您需要一些绑定(bind):

• xlink-v_1_0.xjb
• ows-v_1_0_0.xjb
• filter-v_1_1_0.xjb
• gml-v_3_1_1.xjb

除此之外，我还必须对模式应用一些小补丁，例如将相对模式位置 URL 更正为全局等:

• ogc.patch

但是，实际上，只需采用已编译的模式。这就是这个项目的目的。
