开发简单的Web Services

1.jws方式实例

 编写一个服务类

 

public class HelloWorld{public String sayHello(String name){  return "axis" +name;}}

将这个类的源文件HelloWorld.java 重命名为HelloWorld.jws，并将它复制到Tomcat/webapps/axis目录下，启动tomcat

编写客户端程序，调用上面的服务

package com.liyang.axis.client;import java.rmi.RemoteException;import javax.xml.rpc.ParameterMode;import javax.xml.rpc.ServiceException;import org.apache.axis.client.Call;import org.apache.axis.client.Service;import org.apache.axis.encoding.XMLType;public class HelloWorld {/** * @param args * @throws ServiceException  * @throws RemoteException  */public static void main(String[] args) throws ServiceException, RemoteException {        String endpoint="http://localhost:8080/axis/HelloWorld.jws";        String name="liuyang";        org.apache.axis.client.Service service=new Service();        Call call=(Call) service.createCall();        call.setTargetEndpointAddress(endpoint);        call.setOperationName("sayHello");        call.addParameter("param1", XMLType.XSD_STRING,ParameterMode.IN);        call.setReturnType(XMLType.XSD_STRING);        String set=(String) call.invoke(new Object[]{name});        System.out.println(set);}}

运行，既可以得到结果跑

2.wsdd方式

 编写一个服务类

 

编译这个类。并将class文件复制到tomcat/webapps/axis/web-inf/classes目录下

3.编写文件deploy.wsdd

  

public class HelloWorld{public String <pre name="code" class="html"><?xml version="1.0" encoding="UTF-8"?><deployment xmlns="http://xml.apache.org/axis/wsdd/"            xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"> <globalConfiguration>  <parameter name="adminPassword" value="admin"/>  <parameter name="attachments.Directory" value="./attachments"/>  <parameter name="attachments.implementation"             value="org.apache.axis.attachments.AttachmentsImpl"/>  <parameter name="sendXsiTypes" value="true"/>  <parameter name="sendMultiRefs" value="true"/>  <parameter name="sendXMLDeclaration" value="true"/>  <parameter name="axis.sendMinimizedElements" value="true"/>  <requestFlow>   <handler type="java:org.apache.axis.handlers.JWSHandler">    <parameter name="scope" value="session"/>   </handler>   <handler type="java:org.apache.axis.handlers.JWSHandler">    <parameter name="scope" value="request"/>    <parameter name="extension" value=".jwr"/>   </handler>  </requestFlow> </globalConfiguration> <handler name="LocalResponder"          type="java:org.apache.axis.transport.local.LocalResponder"/> <handler name="URLMapper"          type="java:org.apache.axis.handlers.http.URLMapper"/> <handler name="Authenticate"          type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/> <service name="AdminService" provider="java:MSG">  <parameter name="allowedMethods" value="AdminService"/>  <parameter name="enableRemoteAdmin" value="true"/>  <parameter name="className" value="org.apache.axis.utils.Admin"/>  <namespace>http://xml.apache.org/axis/wsdd/</namespace> </service> <service name="MyService" provider="java:RPC">  <parameter name="allowedMethods" value="*"/>  <parameter name="className" value="com.myaxis.MyService"/> </service><transport name="http">  <requestFlow>   <handler type="URLMapper"/>   <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/>  </requestFlow> </transport> <transport name="local">  <responseFlow>   <handler type="LocalResponder"/>  </responseFlow> </transport></deployment>

sayHello(String name){ return "axis" +name;}}

注意修改上面service的内容

打开命令行，将目录切换到deploy.wsdd所在的目录，

运行：java org.apache.axis.client.AdminClient deploy.wsdd

得到以下结果：

processing file deploy.wsdd

<admin>done processing</admin>

完成部署

编写客户端调用

package com.liyang.axis.client;


import java.rmi.RemoteException;


import javax.xml.rpc.ParameterMode;
import javax.xml.rpc.ServiceException;


import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;


public class HelloWorld {


/**
* @param args
* @throws ServiceException 
* @throws RemoteException 
*/
public static void main(String[] args) throws ServiceException, RemoteException {
        String endpoint="http://localhost:8081/axis/services/MyService";
        String name="liuyang";
        org.apache.axis.client.Service service=new Service();
        Call call=(Call) service.createCall();
        call.setTargetEndpointAddress(endpoint);
        call.setOperationName("sayHello");
        call.addParameter("param1", XMLType.XSD_STRING,ParameterMode.IN);
        call.setReturnType(XMLType.XSD_STRING);
        String set=(String) call.invoke(new Object[]{name});
        System.out.println(set);
}


}
