當這樣的錯誤會發生？Web服務：BeanSerializer

每當元件standardHeader設置爲null，但它被標記爲在XSD nillable="false"。

請詳細說明 – vetri02 2010-01-20 16:00:15

給你的代碼的一些有意義的部分，我會的。 – Bozho 2010-01-20 16:22:01

得到同樣的錯誤，同時創造JAXWS客戶：

2016-03-16 10:42:02 ERROR BeanSerializer:274 - Exception: 
java.io.IOException: Non nillable element 'createDate' is null. 
     at org.apache.axis.encoding.ser.BeanSerializer.serialize(BeanSerializer.java:215)

於是我研究了產生JAXWS類的含量，結果發現：

elemField = new org.apache.axis.description.ElementDesc(); 
     elemField.setFieldName("createDate"); 
     elemField.setXmlName(new javax.xml.namespace.QName("", "createDate")); 
     elemField.setXmlType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string")); 
     elemField.setNillable(false); 
     typeDesc.addFieldDesc(elemField);

代碼的原因

elemField.setNillable(false);

在從WSDL創建JAXWS客戶端時，提供了XSD提供的

。

<xs:complexType name="AddEventRequestType"> 
    <xs:sequence> 
     <xs:element name="id" type="xs:int"/> 
     <xs:element name="createDate" type="xs:string"/>

設置的minOccurs = 0元場XSD，

elemField = new org.apache.axis.description.ElementDesc(); 
    elemField.setFieldName("createDate"); 
    elemField.setXmlName(new javax.xml.namespace.QName("", "createDate")); 
    elemField.setXmlType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string")); 
    elemField.setMinOccurs(0); //it's treated as null value 
    elemField.setNillable(false); 
    typeDesc.addFieldDesc(elemField);
