问题:

从通过目录提供的jar导入其他xsd的xsd生成java类

阴永逸
2023-03-14

我有一些XSD,其中一些共享公共定义。我将这些通用定义分离到一个单独的XSD中。到目前为止,我通过跨项目的相对路径导入了这个common.xsd。Thsi之所以起作用,是因为所有项目都在dame SCM存储库中。

现在,我将这些项目分离到单独的SCM存储库中,并且需要更改对common.xsd的访问,而该访问已经存在于它自己的项目中(common-xml.jar)。

我读到的是:http://www.sagehill.net/docbookxsl/writecatalog.html和https://github.com/highsource/maven-jaxb2-plugin/wiki/using-catalogs,但它不起作用,我也不起作用。不使用目录,xjc在maven-jaxb2-plugin/configuration/schemadirectory中的路径configuret中查找common.xsd

即使添加maven-jaxb2-plugin/configuration/arg>-dxml.catalog.verbosity=999(或者运行mvn-x-dxml.catalog.verbosity=999...,它甚至不会通知读取目录文件。

当我使用XML表单并保留<!doctype..:>元素时,我只获得目录文件的输出,但这会导致超时,因为代理仅允许浏览器连接到internet(公司策略)。

我也读到了这个答案maven-have一个XSD作为一个依赖项,但它会导致同样的问题:xjc在schema目录中查找要包含的文件,但我想避免将它提取到一个地方,在那里它可能会意外地签入SCM。

如何强制xjc查找XSD的位置以导入其他内容?

这是我的maven项目配置:

有时仔细阅读就能解决问题...

https://github.com/highsource/maven-jaxb2-plugin/wiki/using-catalogs:

由于XJC中的bug,这只在未指定schemaLocation时才起作用。因此,不幸的是,下面的组合目前不起作用。

public“http://www.w3.org/1999/xlink”“w3c/1999/xlink.xsd”
http://www.w3.org/1999/xlink.xsd”/">

从导入中删除schemaLocation属性解决了这个问题。

 类似资料:
  • 问题内容: 我有几个重复使用相同实体的XSD。例如,无论是对的XSD 和都有一个在他们的标签来描述产品的问题。因此,我创建了一个文件来定义标记,并同时定义了 两个标记,并使用ProductQuoteRequest.xsdProduct.xsd`。 我想使用Castor从这些XSD生成Java类,并且让他们两个都使用相同的类来表示XSD,这样我就可以重用相同的逻辑将它们映射到模型的类。 Castor

  • 问题内容: 我有一个巨大的QuickBooks SDK .XSD模式文件,该文件定义了我可以从QuickBooks发送/接收的XML请求/响应。 我希望能够轻松地从这些.XSD文件生成Java类,然后将其用于将XML编组为Java对象,以及将Java对象编组为XML。 是否有捷径可寻…? 理想情况下,它在运行时不需要基本Java发行版外部的任何库。但是我很灵活 问题答案: JAXB确实可以满足您的

  • 我有两个XSD,其中一个包含另一个,让我们称它们为A和B。 B有很多xs:complexType定义,并且包含在a中,但是a只对其中的一些定义感兴趣。 现在发生的事情是为B中定义的所有类型生成类。我想要实现的是只为A直接引用的类型生成类。 我曾尝试修改XSD A以导入B,而不是包含,但对于maven jaxb插件来说,效果并不理想。 XSD A导入B: 生成源的插件设置: 我知道有一种方法可以从命

  • 问题:“main.xsd”是一个有效的xml模式文档吗? 当使用解析器(或从python库(该库反过来使用xmllint)进行验证时,我会得到以下错误: 元素“{http://www.w3.org/2001/xmlschema}Element”,属性“ref”:不允许从该架构引用命名空间“http://imported”中的组件,因为没有由import语句指示。WXS架构main.xsd编译失败

  • 与JAXB为给定XSD生成JAXB类类似,Jackson是否提供了从XSD或JSON生成Jackson类的实用程序。 JAXB类geberator已经生成了一组为XSD模式定义的类。例如,对于多态类型,JAXB具有以下注释,以基于XML元素名称来标识名称。 是否可以在杰克逊中创建类似的类。即,基于XML元素名称来标识类型。

  • 有没有什么方法可以从wsdl生成xsd。任何链接或工具也可以。最简单的方法是什么?
