JAXB-在xsd：all内部具有不受限制的maxOccur的元素

假设您仍然可以修改此模型，则可以将角色列表包装为自己的类型，因此最终得到一个

<roles>

<role>

<SearchParams>    <firstname>firstname</firstname>    <lastname>lastname</lastname>    <roles>        <role>role</role>    </roles></SearchParams>

XSD将是

<xsd:schema ... >    <xsd:element name="SearchParams">        <xsd:complexType> <xsd:all>     <xsd:element name="firstname" type="xsd:string" />     <xsd:element name="lastname" type="xsd:string" />     <xsd:element name="roles" type="Roles" /> </xsd:all>        </xsd:complexType>    </xsd:element>    <xsd:complexType name="Roles">        <xsd:sequence> <xsd:element name="role" type="xsd:string" maxOccurs="unbounded" />        </xsd:sequence>    </xsd:complexType></xsd:schema>

而且您将有两个班级。

Roles

Roles

@XmlAccessorType(XmlAccessType.FIELD)@XmlType(name = "", propOrder = {})@XmlRootElement(name = "SearchParams")public class SearchParams {    @XmlElement(required = true)    protected String firstname;    @XmlElement(required = true)    protected String lastname;    @XmlElement(required = true)    protected Roles roles;    ...}@XmlAccessorType(XmlAccessType.FIELD)@XmlType(name = "Roles", propOrder = {    "role"})public class Roles {    @XmlElement(required = true)    protected List<String> role;    ...}

更新

“如果我可以通过这种方式更改模型类，那么这将是解决此问题的好方法。不幸的是，我只允许更改注释”

您可以使用

@XmlList

@XmlAccessorType(XmlAccessType.FIELD)@XmlType(name = "", propOrder = {})@XmlRootElement(name = "SearchParams")public class SearchParams {    @XmlElement(required = true)    protected String firstname;    @XmlElement(required = true)    protected String lastname;    @XmlList    @XmlElement(required = true)    protected List<String> role;    ...}

xsd看起来像

<xsd:element name="SearchParams">    <xsd:complexType>        <xsd:all> <xsd:element name="firstname" type="xsd:string" /> <xsd:element name="lastname" type="xsd:string" /> <xsd:element name="role">     <xsd:simpleType>         <xsd:list itemType="xsd:string" />     </xsd:simpleType> </xsd:element>        </xsd:all>    </xsd:complexType></xsd:element>

注： 如前所述 这里
，这种方法是一种“危险的”，我在文章的开头的解决方案优于使用
