Axis2的部署和应用

Axis2是由大家熟悉的Axis1.x系列演化过来,对它进行了彻底的重写,它使用了新的模块化架构,更方便于功能性的扩展等等。
Axis2支持WS-Addressing、WS-RM、WS-Security和WS-I BasicProfile,WS-Policy将在新版本里得到支持。
Axis2支持更多的data bindings,包括XMLBeans、JiBX、JaxMe和JaxBRI,以及它原生的data binding(ADB)。

 

一、范例测试环境:

     axis2-1.5.1

     jdk1.5.0_15

     apache-tomcat-5.5.23

 

二、部署步骤

     1、将Axis2的二进制工程axis2-1.5.1-bin.zip解压到C:\axis2-1.5.1。设置环境变量AXIS2_HOME=C:\axis2-1.5.1,在Path环境变量追加“%AXIS2_HOME%\bin”串。

 

     2、新增一个web工程(工程名为axis2),将Axis2自带的axis2.war范例中WEB-INF下的conf、lib、modules、services文件夹拷贝到新工程的WEB-INF下。

 

     3、在web.xml文件中增加以下配置信息:

<servlet>
        <servlet-name>Axis2Servlet</servlet-name>
        <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>Axis2Servlet</servlet-name>
        <url-pattern>*.jws</url-pattern>
    </servlet-mapping>

    <servlet-mapping>
        <servlet-name>Axis2Servlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

 

     4、增加一个用于作为WebService发布的java类,源码如下:

package com.achievo.ws;
import com.achievo.bean.UserBean;

public class SimService {
	public String sayHello(String name){
		return "Hello " + name;
	}
	
	public Double getPrice(){
		return 123.45;
	}
	
	public String[] getArray(){
		String[] arr = new String[2];
		arr[0] = "11111";
		arr[1] = "22222";
		return arr;
	}
	
	public UserBean getUser(){
		UserBean user = new UserBean("cjm", "123");
		return user;
	}
}

 

package com.achievo.bean;

public class UserBean {
	private String username;
	private String password;
	
	public UserBean(){
		
	}
	
	public UserBean(String uid, String pwd){
		this.username = uid;
		this.password = pwd;
	}
	
	public String getUsername() {
		return username;
	}
	
	public void setUsername(String username) {
		this.username = username;
	}
	
	public String getPassword() {
		return password;
	}
	
	public void setPassword(String password) {
		this.password = password;
	}
}

 

     5、在WEB-INF\services\目录下新增一个文件夹sim(名称随意),在sim文件夹中增加一个子文件夹META-INF,在META-INF中增加一个名为services.xml的文件,该xml文件的信息如下:

<serviceGroup>
	<service name="SimService" scope="application">
	    <description>Sim Service</description>
	    <messageReceivers>
	        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>
	        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out" class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
	    </messageReceivers>
	    <parameter name="ServiceClass">com.achievo.ws.SimService</parameter>
	</service>
</serviceGroup>

      表示将com.achievo.ws.SimService类以SimService名称发布为WebService。

 

     6、将新工程部署到Tomcat,并启动Tomcat。在浏览器的地址中输入以下URL:

           http://localhost:8888/axis2/services/SimService?wsdl,如果正常显示wsdl定义信息,则表示部署成功。

 

     7、新工程目录结构

Axis2的部署和应用

三、应用范例

     1、在DOS中定位到C:\axis2-1.5.1\bin目录,然后执行以下指令:
         wsdl2java -uri http://localhost:8888/axis2/services/SimService?wsdl -p com.achiveo.ws -s -o stub

 

          -url参数:指定了wsdl文件的路径
          -p参数:指定了生成的Java类的包名
          -o参数:指定了生成的一系列文件保存的根目录

 

     2、将生成的SimServiceStub.java文件引用到测试工程中。

 

     3、测试类代码如下:

public class Test {
	public static void main(String[] args) {
		try{
			SimServiceStub stub = new SimServiceStub();
			
			//方法返回字符串值
			SayHello sayHello = new SimServiceStub.SayHello();
			sayHello.setName("cjm");
			
			SimServiceStub.SayHelloResponse res = stub.sayHello(sayHello);
			String result = res.get_return();
			
			System.out.println(result);
			
			//方法返回double值
			System.out.println(stub.getPrice().get_return());
			
			//方法返回数组
			String[] arr = stub.getArray().get_return();
			if(arr!=null && arr.length>0){
				for(int i=0;i<arr.length;i++){
					System.out.println(arr[i]);
				}
			}
			
			//方法返回bean对象
			SimServiceStub.UserBean user = stub.getUser().get_return();
			System.out.println(user.getUsername() + ", " + user.getPassword());
			
		}catch(Exception ex){
			ex.printStackTrace();
		}
	}
}

  

MonicaServicesImplServiceStub stub = new MonicaServicesImplServiceStub();  

MonicaServicesImplServiceStub.CreatePnr createPnr = new MonicaServicesImplServiceStub.CreatePnr();
createPnr.setArg0(companyCode);
createPnr.setArg1(workNo);
createPnr.setArg2(officeNo);
createPnr.setArg3(pid);
createPnr.setArg4(passengerIds);
createPnr.setArg5(airCodes);
createPnr.setArg6(isDomestic);

CreatePnrE createPnrE = new MonicaServicesImplServiceStub.CreatePnrE();
createPnrE.setCreatePnr(createPnr);

CreatePnrResponseE createPnrResponseE = stub.createPnr(createPnrE);
String result = createPnrResponseE.getCreatePnrResponse().get_return();
System.out.println(result); 

 

如果是通过代理访问公网,那么在调用webservice方法之前需要设置代理属性:

ProxyProperties proxyProperties = new ProxyProperties();   
proxyProperties.setProxyName("xxx.xxx.xxx.xxx");   
proxyProperties.setProxyPort(80);  

options.setProperty(HTTPConstants.PROXY, proxyProperties);
options.setProperty(HTTPConstants.HTTP_PROTOCOL_VERSION, HTTPConstants.HEADER_PROTOCOL_10);
options.setTimeOutInMilliSeconds(10000);

 

也可以将class类打包成aar文件,然后发布成WebService

     1、将class类和services.xml文件拷贝到一个新的目录中,目录结构如下图: 

          class类与包目录结构一致,services.xml文件放到META-INF文件夹中。

Axis2的部署和应用

      2、 在DOS中定位到../aar/sim目录中,然后执行以下命令:

            jar cvf SimService.aar . (注意最后那个点哦),将会在../aar/sim目录中生成SimService.aar文件。

 

       3、将SimService.aar文件拷贝到WEB-INF\services\目录下,此时,services目录的结构应该为:
 

 

四、将Axis2整合到Spring环境

     1、在web.xml文件中增加以下配置信息:

<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

 

     2、将要作为WebService发布的java类配置为一个bean:

<bean id="simService" class="com.achievo.ws.SimService"/>

 

     3、将services.xml文件的内容调整为以下信息:

<serviceGroup>
	<service name="SimService" scope="application">
	    <description>SimService</description>
	    <parameter name="ServiceObjectSupplier">
	    	org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier
	    </parameter>
	    <parameter name="SpringBeanName">simService</parameter>
	    <messageReceivers>
	        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/>
	        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out" class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>
	    </messageReceivers>
	</service>
</serviceGroup>
