Axis2学习的第一天

按照下面，分别建2个工程，一个client（客户端），一个server（服务端）

先实现服务端：

1、编写services.xml文件，该文件是放在aar文件里的META-INF目录下的：

<?xml version="1.0" encoding="UTF-8"?>
<!-- This file was auto-generated from WSDL -->
<!-- by the Apache Axis2 version: 1.4.1  Built on : Aug 19, 2008 (10:13:39 LKT)
     <parameter name="useOriginalwsdl">false</parameter>
     <parameter name="modifyUserWSDLPortAddress">true</parameter>
 -->
<serviceGroup>
    <service name="axis2Service">    
        <description>  
           This is a sample Web Service.  
        </description>  
        <!-- // ServiceClass指定Java Class的位置，即实现服务的类。  --> 
        <parameter name="ServiceClass" locked="false">com.study.axis2.service.impl.Axis2ServiceImpl</parameter>  
        <!-- // operation 与Java Class中方法名对应。  -->   
        <operation name="user">  
            <!-- // messageReceiver看下文注解。    --> 
               <messageReceiver class="com.study.axis2.receive.Axis2MessageReceiverInOut"/>  
        </operation>  
    </service>  
</serviceGroup>

2、编写Axis2ServiceImpl类：

package com.study.axis2.service.impl;

import com.study.axis2.domain.User;
import com.study.axis2.domain.UserResponse;
import com.study.axis2.service.Axis2Service;

public class Axis2ServiceImpl implements Axis2Service {

    public UserResponse user(User user) {
        // 将in转换为String。
        int userId = user.getUserId();
        String userName = user.getUserName();
        
        System.out.println("USER ID : " + userId + "; USER NAME : " + userName);
        
        UserResponse response = new UserResponse();
        response.setRspCode("0000");
        response.setRspDesc("SUCCESS");
        
        return response;
    }

}

3、编写User和UserResponse类：

package com.study.axis2.domain;

public class User {
    
    private int userId;
    private String userName;
    
    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
}

package com.study.axis2.domain;

public class UserResponse {
    
    private String rspCode;
    private String rspDesc;
    
    public String getRspCode() {
        return rspCode;
    }
    public void setRspCode(String rspCode) {
        this.rspCode = rspCode;
    }
    public String getRspDesc() {
        return rspDesc;
    }
    public void setRspDesc(String rspDesc) {
        this.rspDesc = rspDesc;
    }
}

4、编写Axis2MessageReceiverInOut类，用来接收报文的，实际上用Axis2ServiceImpl类来处理业务逻辑，但为了省事，略，直接在InOut类里编写了响应报文：

package com.study.axis2.receive;

import java.io.ByteArrayInputStream;
import java.util.Iterator;

import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axiom.om.impl.builder.StAXOMBuilder;
import org.apache.axiom.soap.SOAPBody;
import org.apache.axiom.soap.SOAPEnvelope;
import org.apache.axiom.soap.SOAPFactory;
import org.apache.axis2.AxisFault;
import org.apache.axis2.context.MessageContext;
import org.apache.axis2.receivers.AbstractInOutMessageReceiver;

public class Axis2MessageReceiverInOut extends AbstractInOutMessageReceiver{
    private static String ENCODEING = "UTF-8";
    private static String NAMING_SPACE = "http://impl.service.axis2.study.com";

    @Override
    public void invokeBusinessLogic(MessageContext envMsg, MessageContext newEnvMsg)
            throws AxisFault {
        System.out.println("------------------------------------");
        String body = envMsg.getEnvelope().getBody().toString();
        System.out.println("request body1 : " + body);
        
        //Axis2Service axis2 = new Axis2ServiceImpl();
        
        StringBuffer soapRequestData = new StringBuffer();
        soapRequestData.append("<userResponse>");
        soapRequestData.append("<rspCode>0000</rspCode>");
        soapRequestData.append("<rspDesc>SUCCESS</rspDesc>");
        soapRequestData.append("</userResponse>");
        
        SOAPEnvelope env = toEnvelope(soapRequestData.toString());
        
        newEnvMsg.setEnvelope(env);
    }
    
    public static SOAPEnvelope toEnvelope(String sourceXml)
    {
        String xmlBody = sourceXml;

        OMFactory of = OMAbstractFactory.getOMFactory();
        OMNamespace bname = of.createOMNamespace(NAMING_SPACE, "");

        SOAPFactory s12f = OMAbstractFactory.getSOAP12Factory();
        SOAPEnvelope s12e = s12f.getDefaultEnvelope();

        try
        {
            byte[] bytes = xmlBody.getBytes(ENCODEING);
            ByteArrayInputStream is = new ByteArrayInputStream(bytes);
            
            StAXOMBuilder builder = new StAXOMBuilder(is);
            
            OMElement elementBody = builder.getDocumentElement();
            //elementBody.setNamespace(bname);
            //addNameSpacePrefix(elementBody, bname);
            
            SOAPBody s12b = s12e.getBody();
            s12b.addChild(elementBody);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        return s12e;
    }

    public static OMElement addNameSpacePrefix(OMElement element,
            OMNamespace prefix)
    {
        if (element.getChildElements() != null)
        {
            Iterator<OMElement> it = element.getChildElements();
            element.setNamespace(prefix);
            while (it.hasNext())
            {
                OMElement childelement = (OMElement) it.next();
                childelement.setNamespace(prefix);

                if ((childelement.getChildElements() == null)
                        || (!childelement.getChildElements().hasNext()))
                    continue;
                addChildNameSpacePrefix(childelement.getChildElements(), prefix);
            }
        }

        return element;
    }

    public static void addChildNameSpacePrefix(Iterator element,
            OMNamespace prefix)
    {
        if (element != null)
        {
            while (element.hasNext())
            {
                OMElement childelement = (OMElement) element.next();

                childelement.setNamespace(prefix);
                if ((childelement.getChildElements() == null)
                        || (!childelement.getChildElements().hasNext()))
                    continue;
                addChildNameSpacePrefix(childelement.getChildElements(), prefix);
            }
        }
    }

}

5、将该类和services.xml文件都放在axis2service.aar下 ,并在WEB-INF/services/services.list文件下增加axis2service.aar：

axis2service.aar
version-1.6.2.aar

服务端编写好，发布，http://localhost:8082/axis2_server_150701/services/axis2Service?wsdl

axis2可以访问http://localhost:8082/axis2_server_150701/services/listServices来查看发布了哪些接口：

以上服务端已完全搭好，现编写客户端client，服务端增加个User类：

package com.study.axis2.client;

import java.io.ByteArrayInputStream;
import java.io.InputStream;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.RequestEntity;

import com.study.axis2.domain.User;


public class Axis2Client {
    private static String url = "http://localhost:8082/axis2_server_150701/services/axis2Service";

    public static void main(String[] args) {
    
        User user = new User();
        user.setUserId(11111);
        user.setUserName("66666");
        
        HttpClient client = new HttpClient();
        PostMethod method = new PostMethod(url);
        StringBuffer soapRequestData = new StringBuffer();
        soapRequestData.append("<?xml version="1.0" encoding="utf-8"?>");
        soapRequestData
                .append("<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance""
                        + " xmlns:xsd="http://www.w3.org/2001/XMLSchema""
                        + " xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">");
        soapRequestData.append("<soap12:Body>");
        soapRequestData.append("<user xmlns="http://impl.service.axis2.study.com">");
        soapRequestData.append("<userId>" + user.getUserId() + "</userId>");
        soapRequestData.append("<userName>" + user.getUserName() + "</userName>");
        soapRequestData.append("</user>");
        soapRequestData.append("</soap12:Body>");
        soapRequestData.append("</soap12:Envelope>");
        
        String xml = soapRequestData.toString();
        
        byte[] b;
        
        try
        {
            b = xml.getBytes("utf-8");
            
            System.out.println("request : " + xml);
            InputStream is = new ByteArrayInputStream(b, 0, b.length);
            RequestEntity re = new InputStreamRequestEntity(is, b.length, "application/soap+xml; charset=utf-8");
            method.setRequestEntity(re);
            
            client.executeMethod(method);
            String response = method.getResponseBodyAsString();
            System.out.println("response : " + response);
        } 
        catch (Exception e) 
        {
            e.printStackTrace();
        }
    }
    
}

执行客户端代码，输出（输出结果内容为xml，稍微format下）：

request : 
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
    <soap12:Body>
        <user xmlns="http://impl.service.axis2.study.com">
            <userId>11111</userId>
            <userName>yff</userName>
        </user>
    </soap12:Body>
</soap12:Envelope>
response : 
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
    <soapenv:Body>
        <userResponse>
            <rspCode>0000</rspCode>
            <rspDesc>SUCCESS</rspDesc>
        </userResponse>
    </soapenv:Body>
</soapenv:Envelope>
