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>
