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);

}

}
