jaxb2简化了xs:choice的具有相同类型的插件 [英] jaxb2 simplify plugin for xs:choice having same types
问题描述
我正在尝试将jaxb2基础简化插件用于我的架构到JAXB的转换.
对于下面的复杂类型，它工作正常.在xs:choice内部定义的每个元素都有不同的类型(type1和type2).
I'm trying to use jaxb2 basics simplify plugin for my schema to JAXB conversion.
It works fine for the complex types like below. Each element is defined inside the xs:choice has different types (type1 and type2).
sample.xsd(具有不同类型的复杂选择类型)
<xs:complexType name="doclist">
<xs:sequence>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:annotation>
<xs:appinfo>
<simplify:as-element-property />
</xs:appinfo>
</xs:annotation>
<xs:element name="document1" type="type1" />
<xs:element name="document2" type="type2" />
</xs:choice>
</xs:sequence>
<xs:attribute name="heading" type="xs:string" />
</xs:complexType>
但是，如果复杂类型包含多个具有相同类型(xs:string)的元素，如下所示，则maven安装会引发错误.
But if the complex type contains more than one element with same type (xs:string), as shown below, then maven install throws error.
sample.xsd(具有相同类型的复杂选择类型)
<xs:complexType name="addressTEST">
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:annotation>
<xs:appinfo>
<simplify:as-element-property />
</xs:appinfo>
</xs:annotation>
<xs:element name="street" type="xs:string" />
<xs:element name="city" type="xs:string" />
</xs:choice>
</xs:complexType>
如果我为多个元素使用相同类型， jaxb2简化是否行不通?
Does jaxb2 simplify will not work if I have same types for more than one elements ?

推荐答案
它应该可以工作，但是请尝试自定义xs:element之一.
It should work, but try customizing one of the xs:elements instead.
根据生成的属性类型，您需要自定义xs:choice或子级xs:elements之一.
Depending on the property type produced, you'll need to customize either xs:choice or one of the child xs:elements.
如果获得元素"属性，请自定义xs:choice.参见文档.这是第一种情况.
If you get an "elements" property, customize xs:choice. See the documentation. This is what you have in the first case.
如果获得元素引用"属性，请自定义xs:elements之一.参见文档.这是第二种情况.
If you get an "element references" property, customize one of the xs:elements. See the documentation. This is what you have in the second case.
