我正在尝试使用JAXB来为该架构生成类: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,我发现我需要使用一个绑定(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,当我使用该绑定(bind)文件时,会遇到很多其他错误:

我有点惊讶,只是因为这似乎是其他人会为其生成JAXB类的架构,但是google似乎并没有提出任何建议。我以前使用过JAXB,但它似乎比过去更复杂。
是否有需要用于此模式的特定绑定(bind)文件,或者某些特定的JAXB设置?
最佳答案
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的OGC模式,包括WFS 1.1.0。
OGC模式很难编译。您需要大量的绑定(bind),自定义项,有时还需要补丁程序。因此,我的建议是仅使用ogc-schemas项目提供的已编译模式。为编译的WFS 1.1.0模式获取this artifact。
对于WFS 1.1.0,您将需要一些绑定(bind):
除此之外,我还必须对架构应用一些次要补丁,例如将相对架构位置URL更正为全局等:
但是,实际上,只需采用已经编译的架构即可。这就是这个项目的目的。
