我正在尝试对生成的 JAXB 类强制执行枚举验证，但是在绑定它们时遇到了一些问题。

基本的 XSD 设置是：

-enumsXSD
-2 other XSDs that import this XSD

为了证明我的课程重复我正在使用剧集，但是在 enumsXSD 中添加注释时看起来这并不好

com.sun.istack.SAXParseException2: compiler was unable to honor this annox:annotateEnumValueMethod customization. It is attached to a wrong place, or its inconsistent with other bindings.

[ERROR] Error while generating code.Location [ file:somewhere/generic.episode{64,99}].
com.sun.istack.SAXParseException2: (the above customization is attached to the following location in the schema)

并在枚举 XSD

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema elementFormDefault="qualified" id="commonEnums"
           targetNamespace="http://foo.com/xsd/commons/enum"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
           jaxb:version="2.1"
           xmlns:annox="http://annox.dev.java.net"
           jaxb:extensionBindingPrefixes="annox">
<xs:simpleType name="bulletinCategory">
    <xs:annotation>
      <xs:appinfo>
        <annox:annotateEnumValueMethod>@java.lang.Deprecated</annox:annotateEnumValueMethod>
      </xs:appinfo>
    </xs:annotation>
    <xs:restriction base="xs:string">
      <xs:enumeration value="valueA" />
      <xs:enumeration value="valueB" />
      <xs:enumeration value="valueC" />
    </xs:restriction>
  </xs:simpleType>
</xs>

理想情况下，@deprecated 应该是@XmlJavaTypeAdapter(FooAdapter.class)，但我认为让我们从小处着手。

问题可能是您已将自定义直接包含在enums.xsd. 因此，当您编译其他模式时，也会考虑这些自定义。

但是由于您似乎也使用enums.xsdas 插曲，因此这有效地防止了枚举类的生成。如果没有枚举类，则无法应用自定义，因此它们不会被标记为“已识别”，这会产生您得到的错误。

为了解决这个问题，在编译时enums.xsd，只需将自定义项移动到单独的绑定文件中并在编译期间使用它。

然后，在编译其他模式时，将enums.xsd其用作插曲，但不要将绑定文件与enums.xsd.
