java - CXF JAXB XSD 问题

Question

我有一个 Web 服务，它接收用户定义的数据类型，由各种字段组成，其中一个是我定义为的数据类型百分比

 <xsd:simpleType name="Percentage">
    <xsd:restriction base="xsd:decimal">
        <xsd:minInclusive value="0"/>
        <xsd:maxInclusive value="1"/>
    </xsd:restriction>
</xsd:simpleType>

以下是我收到的警告，有什么想法我哪里出错了吗？我从 SOAP UI 测试 Web 服务，所以我假设这与我使用服务的方式无关，添加：我首先有一个 SOAP Web 服务代码 CXF，用于创建 XSD 然后生成类的数据类型，使用xjc. 也许我需要在 Java 类的注释中添加一些东西来显式设置命名空间？

 WARN  [EndpointReferenceUtils]: SAXException for newSchema()
 org.xml.sax.SAXParseException: src-resolve.4.2: Error resolving component 'ns0:Percentage'. It was detected that 'ns0:Percentage' is in namespace 'http://www.xyz.ie/cb/projections/converter/model/common', but components from this namespace are not referenceable from schema document 'file:///C:/_dev_env_/CBProjectionsWebService/trunk/cb-projections-jetty/schema3.xsd'. If this is the incorrect namespace, perhaps the prefix of 'ns0:Percentage' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:///C:/_dev_env_/CBProjectionsWebService/trunk/cb-projections-jetty/schema3.xsd'.

（答案的长格式：）

您没有显示相关代码（如果这样做，您的问题会更好），但猜测您的 Percentage 类型在另一个模式文档中被引用，例如 CBProjectionsWebService/trunk/cb-projections-jetty/ schema3.xsd。

该模式文档包括一个命名空间声明，将某个前缀（猜测为ns0）绑定到命名空间http://www.xyz.ie/cb/projections/converter/model/common，并使用带有该前缀的 Qname 引用类型（例如 ns0:Percentage）。

但是，声明命名空间前缀是不够的：XSD 要求如果您从具有给定目标命名空间的模式文档中引用不同命名空间中的组件，则必须导入该其他命名空间。所以——正如错误消息所说——你需要在模式文档中包含一个导入：

<xsd:import namespace=
  "http://www.xyz.ie/cb/projections/converter/model/common"
/>

在某些情况下，您可能还想告诉系统在哪里可以找到该命名空间的架构文档：

<xsd:import namespace=
  "http://www.xyz.ie/cb/projections/converter/model/common"
  schemaLocation="..."
/>

一般来说，如果您将实际位置限制为验证器的调用或单个驱动程序文件，这是一个好主意并有助于模式处理器之间的互操作性，但是许多人在忽略此规则的情况下过着幸福和富有成效的生活，所以请弥补您的自己的想法。

（答案的简短形式：）
