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 为这个模式生成类：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 &lt;jaxb:property> to resolve this conflict.
  line 261 of http://www.w3.org/1999/xlink.xsd

经过一番谷歌搜索，我发现我需要使用绑定文件：

<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>

但是当我使用该绑定文件时，我得到了大量其他错误：

我有点惊讶，只是因为这似乎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多。

是否有我需要用于此模式的特定绑定文件，或者可能是一些特定的 JAXB 设置？

免责声明：我是ogc-schemas项目的主要开发人员，该项目编译了几乎所有 OGC 模式，包括WFS 1.1.0。

OGC Schema 的编译问题很大。你需要大量的绑定、自定义，有时还需要补丁。所以我的建议是使用ogc-schemas项目提供的已经编译好的 schmeas。为已编译的 WFS 1.1.0 模式获取此工件。

对于 WFS 1.1.0，您需要一些绑定：

除此之外，我还必须对架构应用一些小补丁，例如将相对架构位置 URL 更正为全局等：

ogc补丁

但是，实际上，只需采用已经编译的模式。这就是这个项目的意义所在。
