我写了一些webservices，其中一些返回一个简单的String（这个工作）和其他返回一个对象列表。不，axis2（1.5.1）无法处理集合类型，因此我将返回类型更改为Object[]但仍然接受此异常

该服务由eclipse提供的向导创建。 axis2无法返回这些对象吗？只返回原始类型不符合我的需要。
答案 0 :(得分：2)
Axis找不到能够翻译您通过XML发送的对象所需的映射。它不知道如何将XML转换为对象，反之亦然。一个好主意是返回一个包含对象数组的对象。
使用Axis，您必须告诉它如何在XML和对象之间进行映射。这是使用WSDL和Classes本身定义的。
1）查看Web服务生成的WSDL：您可以通过查看http://localhost:8080/Service?wsdl找到它。检查一下就可以了。
2）Axis通过查看Class.getTypeDesc（）的返回值来查找它的映射;检查此映射是否正确。
对于我的一个服务，我将以下映射定义为Web服务的返回值（类RechercherBatimentRetour，Retour的子类）。
typeDesc.setXmlType(new QName("sbatimentto", "RechercherBatimentRetour")); // 1
org.apache.axis.description.ElementDesc elemField = new org.apache.axis.description.ElementDesc();
elemField.setFieldName("batiments");
elemField.setXmlName(new QName("", "batiments")); // 2
elemField.setXmlType(new QName("sbatimentto", "ResumeBatimentTo"));
elemField.setNillable(true);
typeDesc.addFieldDesc(elemField);
这是定义此SOAP服务的返回值。
// 1 - ＆gt;这就是说WSDL ComplexType RechercherBatimentRetour位于命名空间'sbatimentto'。
// 2 - ＆gt;我们将字段'batiments'添加到ComplexType中，ComplexType是通过类中的getter和setter定义的：
public ResumeBatimentTo[] getBatiments() {
return batiments;
}
public void setBatiments(ResumeBatimentTo[] batiments) {
this.batiments = batiments;
}
ResumeBatimentTo也在同一名称空间中。所以这最终得到一个包含（其他东西）的WSDL
<complexType name="Retour">
<sequence>
<element name="codeRetour" nillable="true" type="xsd:string"/>
<element name="message" nillable="true" type="xsd:string"/>
<element name="statut" type="xsd:boolean"/>
</sequence>
</complexType>
<complexType name="RechercherBatimentRetour">
<complexContent>
<extension base="tns1:Retour">
<sequence>
<element name="batiments" nillable="true" type="impl:ArrayOf_tns1_ResumeBatimentTo"/>
</sequence>
</extension>
</complexContent>
</complexType>
所有使用过的类必须有getTypeDesc，getSerializer＆amp;正确定义了getDeserializer以便能够使用。

实际上，Web服务方法的返回类型应该是非泛型的。
它不应该是Object，也不应该只是List ...
所以，返回一个特定的Person类对象..如果Person类的一个对象需要返回 或者如果对象列表在那里.....使用...列表.....
做改变....并享受...... !!!!!
