CXF解组日期不接受NULL值

Question

我有一个包含-的WSDL文件

<xs:complexType name="PNV">
<xs:sequence>
<xs:element name="dataType" type="xsd:int" />
<xs:element name="multiValued" type="xsd:boolean" />
<xs:element name="booleanValue" type="xsd:boolean" />
<xs:element name="dateValue" nillable="true" type="xsd:dateTime" />
..........

然后它被转换成这样的Java文件-

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "PNV", propOrder = {
"dataType",
"multiValued",
"booleanValue",
"dateValue",
})
public class PNV
implements Serializable
{
private final static long serialVersionUID = 1L;
protected int dataType;
protected boolean multiValued;
protected boolean booleanValue;
@XmlElement(required = true, type = String.class, nillable = true)
@XmlJavaTypeAdapter(Adapter1 .class)
@XmlSchemaType(name = "dateTime")
protected Date dateValue;
}

绑定文件-

<jaxws:bindings  node="wsdl:definitions/wsdl:types/xs:schema[@targetNamespace='http://changeservice.xxservices.service.xx']">      
<jxb:globalBindings xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema">        
<jxb:javaType name="java.util.Date" xmlType="xs:dateTime" 
parseMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.parseDateTime"
printMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.printDateTime"/>    
<jxb:serializable uid="1"/>     
</jxb:globalBindings>  
</jaxws:bindings>

在我的SOAPUI测试案例中，我通过了

<dateValue nil="true"/>

但它给了我以下错误-

Caused by: java.lang.IllegalArgumentException:

at com.sun.xml.bind.v2.runtime.reflect.AdaptedAccessor.set(AdaptedAccessor.java:55) ~[jaxb-runtime-2.3.3.jar:2.3.3]

我检查了Adapter1类中的date属性，它是空的，而不是null，所以它抛出了一个错误。我的问题是，为什么即使我在SOAPUI测试用例中传递nil=true，它也不取NULL值。为什么它是空白的？我还试图从我的输入请求中完全删除这个dateValue字段，但它仍然给了我相同的日期字段错误。

我还尝试使用XMLGregorianCalendar作为日期值的类型，但当我在SOAPUI中传递nil=true时，它会给我同样的错误消息。。请帮忙。

这个链接帮助了我：https://blogs.oracle.com/rammenon/specifying-null-content-in-your-xml-document-using-nillable-and-xsi:nil

我添加了xmlns:xsi＝"；http://www.w3.org/2001/XMLSchema-instance在我的SOAPUI测试&添加日期值作为

<dateValue xsi:nil="true"/>

如果您无法更改wsdl文件(在由外部系统提供的情况下(，您可以覆盖标准org.apache.cxf.xjc.runtime.DataTypeAdapter

问题的根不是null，而是空字符串，作为parseDateTime方法的输入参数。

1. 创建类似于"；org.apache.cxf.xjc.runtime.DataTypeAdapter"；对空字符串进行额外检查

   public class DateAdapter  {
   public static Date parseDateTime(String s) {
   if (s == null||s.isEmpty()) {
   return null;
   }
   return DatatypeConverter.parseDateTime(s).getTime();
   }
   public static String printDateTime(Date dt) {
   if (dt == null) {
   return null;
   }
   Calendar c = Calendar.getInstance();
   c.setTime(dt);
   return DatatypeConverter.printDateTime(c);
   }
   

   }

2. 在绑定文件中指定新类

<jaxws:bindings  node="wsdl:definitions/wsdl:types/xs:schema[@targetNamespace='http://changeservice.xxservices.service.xx']">      
<jxb:globalBindings xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema">        
<jxb:javaType name="java.util.Date" xmlType="xs:dateTime" 
parseMethod="your_class_here.parseDateTime"
printMethod="your_class_here.printDateTime"/>    
<jxb:serializable uid="1"/>     
</jxb:globalBindings>  
</jaxws:bindings>
