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

我将该架构下载到本地文件，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

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，我收到了大量其他错误：

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

是否有我需要为此模式使用的特定绑定文件，或者某些特定的 JAXB 设置？

Answer 1

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

OGC 模式的编译问题很大。 您需要大量绑定、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：

• xlink-v_1_0.xjb
• ows-v_1_0_0.xjb
• 过滤器-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即可。 这就是这个项目的意义所在。

@lexicore我在尝试为WFS 2.0生成JAXB类时遇到相同的问题。 我需要在客户端中使用它们来与WFS 2.0.0一起使用。不幸的是，在mavenrepository中，没有用于WFS 2.0架构的JAR（org.geotools.schemas»wfs-2。）只有wfs.xsd文件。 我想念什么吗？
