JAXB xjc generates fields as a list of elements

Question

I have a problem with the following sequence of a wsdl file

                <xsd:sequence>
                <xsd:element maxOccurs="1" minOccurs="1" name="allowCaseWithNewContract" type="xsd:boolean">
                </xsd:element>
                <xsd:choice minOccurs="0">
                    <xsd:element name="validationError" type="mnp:ErrorType"/>
                    <xsd:element name="internalError" type="mnp:ErrorType"/>
                    <xsd:element name="businessError" type="mnp:ErrorType"/>
                    <xsd:element name="externalError" type="mnp:ErrorType"/>
                </xsd:choice>
            </xsd:sequence>

            <xsd:sequence>
                <xsd:element maxOccurs="1" minOccurs="1" name="allowCaseWithExistingContract" type="xsd:boolean">
                </xsd:element>
                <xsd:choice minOccurs="0">
                    <xsd:element name="validationError" type="mnp:ErrorType"/>
                    <xsd:element name="internalError" type="mnp:ErrorType"/>
                    <xsd:element name="businessError" type="mnp:ErrorType"/>
                    <xsd:element name="externalError" type="mnp:ErrorType"/>
                </xsd:choice>
            </xsd:sequence>

I tried to use jaxb binding customization :

<?xml version="1.0" encoding="UTF-8"?>
<jxb:bindings xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
              xmlns:xs="http://www.w3.org/2001/XMLSchema"
              xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc">
  <jxb:globalBindings>
    <xjc:simple />
  </jxb:globalBindings>
</jxb:bindings>

I'm trying to avoid jaxb - xjc from generating my fields as a List<JAXBElement<?>> validationErrorsAndAllowCaseWithExistingContractsAndInternalErrors , is there anyway I could accomplish that?

Answer 1

I advise you to simplify the schema if possible. I would put the allowCaseWithNewContract and allowCaseWithExistingContract as attributes in the enclosing element. I guess then, the remaining choice would have the type ErrorType .

我不允许发表评论，但是我相信这个问题在这里和这里都已经得到解决-基本上，您最好的选择是使用JAXB2简化插件，因为JAXB会阻止您执行想要的（反序列化）操作从XML到Java前后均保持一致（即，您需要保留顺序）。
