小白轻松使用axis2构建webservice

# 引言： #

**使用axis2是来实现webservice接口是比较常见的，就我来说，如果要学一个首次接触东西，简单了解相关基础概念后，就希望自己能够简单快速的实现一个例子，在学习一门开发语言的时候，一个helloWorld例子能够快速的让你入坑，今天也来写一个小白快速入坑的helloWorld。**

# 实现思路 #

1.  **下载好相关jar包；**
2.  **创建web工程，给web工程的lib引入这些jar包；**
3.  **书写接口实现类；**
4.  **创建和配置service.xml文件，配置web.xml；**
5.  **编写测试类**

# 具体实现 #

## 获取jar包 ##

**1.可以axis的官网下载，具体就不说明了。**

**2.文章末尾下载源码，源码里面有下载好的jar包，jar包列表如下：**

## 创建web工程、创建相关目录 ##

## 编写接口实现类 ##

package com;
    
    public class HelloWorld {
       
        public String sayHello(String name){return "Hello， "+name+".";}
        public String saySorry(String name){return "Sorry,"+name+".";}
        public String getWorld(){return "Hello,World";}
    
    }

## **配置service.xml** ##

**配置详情**

<service name="HelloWorld">  
        <description>  
            HelloWorld Service Example
        </description>  
        
        <parameter name="ServiceClass">  
            com.HelloWorld
        </parameter>  
        
        <operation name="sayHello">  
            <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />  
        </operation>  
        <operation name="saySorry">  
            <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />  
        </operation>  
        <operation name="getWorld">  
            <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />  
        </operation>  
    </service>

## 配置web.xml ##

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    	<welcome-file-list>
    		<welcome-file>index.jsp</welcome-file>
    	</welcome-file-list>
    
    	<servlet>
    		<servlet-name>AxisServlet</servlet-name>
    		<servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
    		<load-on-startup>1</load-on-startup>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>AxisServlet</servlet-name>
    		<url-pattern>/services/*</url-pattern>
    	</servlet-mapping>
    </web-app>

## 部署到tomcat，启动服务器 ##

**输入地址：**[http://localhost:8080/helloWorldWebService/services/HelloWorld?wsdl][http_localhost_8080_helloWorldWebService_services_HelloWorld_wsdl]

描述：（[http://localhost:8080/][http_localhost_8080_helloWorldWebService_services_HelloWorld_wsdl] + 工程名 + / + web.xml里面的(services) + / + services.xml的指定服务名 + ?wsdl）

## 测试 ##

**1.可以直接通过soupui来测试**

**2.编写测试类（就直接在这个工程下编写，不另外开工程了）**

package client;
    
    import javax.xml.namespace.QName;
    
    import org.apache.axis.client.Call;
    import org.apache.axis.client.Service;
    
    public class TestMain {
    	public static void main(String args[]) {
    
    		try {
    			String xmlInfo = "abc";
    			String webServiceUrl = "http://localhost:8080/helloWorldWebService/services/HelloWorld?wsdl";
    			Service service = new Service();
    			Call call = (Call) service.createCall();
    			String url = webServiceUrl.replace("?wsdl", "");
    			call.setTargetEndpointAddress(url);
    			call.setTimeout(20000);
    			// call.setOperationName(new QName("http://com", "sayHello"));
    
    			// call.setOperationName(new QName("http://com", "saySorry"));
    
    			call.setOperationName(new QName("http://com", "getWorld"));
    
    			String retVal = (String) call.invoke(new Object[] { xmlInfo });
    			System.out.println("返回：" + retVal);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    
    	}
    }

**右键执行这个测试类**
