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
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。
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>
