我已经使用xew 插件创建了一个带有 cxf 的 web 服务客户端,用于列表展开
问题是null
列表中的 消失了。例如:
我有一个List<String>
带有字符串和null
-entry的请求
当请求现在到达服务器时,它只包含字符串而不是null
条目。所以示例列表中只有 2 个条目。
这是 wsdl 的示例:
[..]
<!-- the request -->
<xsd:element name="createGroup">
<xsd:complexType>
<xsd:sequence>
<xsd:element maxOccurs="1" minOccurs="1" name="in0" nillable="true" type="xsd:string"/>
<xsd:element maxOccurs="1" minOccurs="1" name="in1" nillable="true" type="ns2:ArrayOfRole"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
[..]
<!-- the list which will be unwrapped -->
<xsd:complexType name="ArrayOfRole">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" minOccurs="0" name="Role" nillable="true" type="xsd:String"/>
</xsd:sequence>
</xsd:complexType>
我正在使用 maven 生成 ws 客户端

样品请求:
final CreateGroup create = new CreateGroup();
create.setIn0("newgroup");
final List<String> roles = new ArrayList<String>();
roles.add("testrole");
roles.add(null);
roles.add("testrole2");
create.setIn1(roles);
final SamplePortType proxy = ..;
proxy.createGroup(create);
有没有办法让null
条目仍然存在于服务器端?
