由于最近公司采用Web Services技术做企业应用集成(EAI)相关的项目,有关技术人员反应采用Axis不能传
递用户自定义对象。 错误信息大体如下: AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelo
pe/}Server.userException faultSubcode: faultString: java.io.IOException: No serializer found for class com.whcyit.axis.SimpleObject in registry org.apache.axis.encoding.TypeMappingDelegate@da3a1e faul
tActor: faultNode: faultDetail: {http://xml.apache.org/axis/}stackTrace:java.io.IOException: No serializer
found for class com.whcyit.axis.SimpleObject in registry org.apache.axis.encoding.TypeMappingDelegate@da3a1e at org.apache.axis.encoding.SerializationContext.serializeActual(SerializationContext.java:1429) 对于Web Services的接触已经是4年多前的事情了,基本上对于Web Services只是存在一个概念了。抱着疑问,
决定自己试一下到底怎么回事?最后通过2个多小时的测试,终于把问题解决了。解决方式如下:
1. 在Axis服务端,注册自定义对象的序列化/反序列化器主要是修改axis安装目录下WEB-INF/server-confi
g.wsdd文件。
<service name="SimpleObjectService" provider="java:RPC"> <parameter name="all
owedMethods" value="*"/> <parameter name="className" value="com.whcyit.axis.S
impleObjectService"/> <beanMapping languageSpecificType="java:com.whcyit.axis.
SimpleObject" qname="ns:SimpleObject" xmlns:ns="urn:BeanService"/></service>
注意service/beanMapping的定义。languageSpecificType中定义使用那个类, qname定义类的名称。
2. 在Axis客户端,注册自定义对象的序列化/反序列化器。 核心代码如下:
//创建调用对象
Service service = new Service();
Call call = null;
call = (Call) service.createCall();
//注册SimpleObject的序列化类型
QName qn = new QName("urn:BeanService","SimpleObject");
call.registerTypeMapping(SimpleObject.class, qn, new BeanSerializerFactory(
SimpleObject.class, qn), new BeanDeserializerFactory(SimpleObject.class, qn));全部代码示例如下: //SimpleObject.java
//Web Service对象传递的对象// SimpleObjectService.java //服务程序
package com.whcyit.axis;
import java.io.Serializable;
public class SimpleObject implements Serializable {
/** * */
private static final long serialVersionUID = -6414428095965735488L;

public void setFloat(float f) { this.f = f; }
public int getInt() { return i; }
public void setInt(int i) { this.i = i; }
public String getString() { return str; }
public void setString(String str) { this.str = str; }}
package com.whcyit.axis;
public class SimpleObjectService {
public String sayHello(String name) {
return "Hello " + name +"!"; }
public String getString(SimpleObject obj) {
System.out.println("SimpleObjectService getString invoked!");
return "return by serviced:"+obj.getString(); }
public SimpleObject createSimpleObject(int i,float f,String str) {
System.out.println("SimpleObjectService createSimpleObject invoked!");// SimpleObjectClient.java //客户端调用文件
SimpleObject so = new SimpleObject();
so.setInt(i);
so.setFloat(f);
so.setString(str);
return so; } }
