基于Axis的自定义对象序列化

时间:2021-08-19 15:57:53

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
package com.whcyit.axis;
import java.io.Serializable;
public class SimpleObject implements Serializable {  
   /**    *     */  
private static final long serialVersionUID = -6414428095965735488L;  
  private int i = 0;    
private float f = 0.0f;    
private String str = "";        
public SimpleObject() {        }    
public float getFloat() {    return f;    }    
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;    }}
// SimpleObjectService.java //服务程序
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!");    
SimpleObject so = new SimpleObject();    
so.setInt(i);    
so.setFloat(f);    
so.setString(str);    
return so;        } }
   // SimpleObjectClient.java //客户端调用文件
package com.whcyit.axis; 
import javax.xml.namespace.QName;
import org.apache.axis.client.Call;import org.apache.axis.client.Service;import
org.apache.axis.encoding.ser.BeanDeserializerFactory;
import org.apache.axis.encoding.ser.BeanSerializerFactory;
public class SimpleObjectClient {     /**    * @param args    */    
public static void main(String[] args) {    
String ret = "";    
try {    String wsdlUrl = "http://localhost:8080/axis/services/SimpleObjectService?
wsdl";    String nameSpaceUri = "http://localhost:8080/axis/services/
SimpleObjectService";    
//String wsdlUrl = "http://10.68.19.24:8080/sample/services/SimpleObjectService?
wsdl";    
//String nameSpaceUri = "http://10.68.19.24:8080/sample/services/
SimpleObjectService";     

//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));     

//调用sayHello    
System.out.println(">>>sayHello");    
call.setOperationName(new QName(nameSpaceUri, "sayHello"));    
call.setTargetEndpointAddress(new java.net.URL(wsdlUrl));     
ret = (String) call.invoke(new Object[] { "liu2" });    
System.out.println("return value is " + ret);        

//调用getDesc    
System.out.println(">>>getString");    
SimpleObject so = new SimpleObject();    
so.setString("hello!");    
QName getDescQn = new QName(nameSpaceUri, "getString");    
call.setOperationName(getDescQn);    
call.setTargetEndpointAddress(new java.net.URL(wsdlUrl));    
ret = (String) call.invoke(new Object[] { so });    
System.out.println("return value is " + ret);        

//调用createSimpleObject    
System.out.println(">>>createSimpleObject");   
 QName getObjectQn = new QName(nameSpaceUri, "createSimpleObject");     
call.setOperationName(getObjectQn);    
call.setTargetEndpointAddress(new java.net.URL(wsdlUrl));    
SimpleObject rtnSO = (SimpleObject) call.invoke(new Object[] 
{ new Integer(1),new Float(0.1f),"liu2" });    
System.out.println("return object " + rtnSO.getString());    
} catch (Exception ex) {    ex.printStackTrace();    }    } }
