Question

我正在尝试对生成的JAXB类强制执行枚举验证，但是我遇到了一些限制它们的问题。

基本的XSD设置是：

-enumsXSD
-2 other XSDs that import this XSD

为了防止我的课程重复，我正在使用剧集，但在enumsXSD中添加注释时看起来这并不好看

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)

              <!-- Set the package of the generated code -->
              <generatePackage>com.foo.something</generatePackage>
              <generateDirectory>${project.build.directory}/generated-sources/xjc1/a_something</generateDirectory>

              <!-- Define the directory where we should find the XSD files -->

            </configuration>
          </execution>
     </executions>
   <plugin>
</plugins>

并在枚举XSD中

<?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做起。

问题可能是您已将自定义项直接包含在enums.xsd中。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.xsd作为剧集，这有效地防止了枚举类的生成。如果没有枚举类，则无法应用自定义项，因此未将其标记为＆＃34;已识别＆＃34;这会产生你得到的错误。

要解决此问题，在编译enums.xsd时，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，使用enums.xsd作为剧集，但不使用该绑定文件和enums.xsd的自定义。

Jaxb2-annotate-plugin不适用于剧集
