基于Axis的自定義對象序列化

1. 在Axis服務端，注冊自定義對象的序列化/反序列化器
主要是修改axis安裝目錄下WEB-INF/server-config.wsdd文件。

<service name="SimpleObjectService" provider="java:RPC">

  <parameter name="allowedMethods" value="*"/>

  <parameter name="className" value="com.whcyit.axis.SimpleObjectService"/>

  <beanMapping languageSpecificType="java:com.whcyit.axis.SimpleObject" 

	qname="ns:SimpleObject" xmlns:ns="urn:BeanService"/>

</service>

注意service/beanMapping的定義。languageSpecificType中定義使用那個類, qname定義類的名稱。

2.  在Axis客戶端，注冊自定義對象的序列化/反序列化器。

核心代碼如下：

//創(chuàng)建調(diào)用對象

Service service = new Service();

Call call = null;

call = (Call) service.createCall();

//注冊SimpleObject的序列化類型

QName qn = new QName("urn:BeanService","SimpleObject");

call.registerTypeMapping(SimpleObject.class, qn,

        new BeanSerializerFactory(SimpleObject.class, qn),

        new BeanDeserializerFactory(SimpleObject.class, qn));

全部代碼示例如下：

//SimpleObject.java

//Web Service對象傳遞的對象，必需繼承Serializable

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

//服務程序

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;

       }

 }
