基于axis2的webservice

最近在学习webservices，看官网说明，觉得挺简单，写篇文章供大家参考。//具体作用就不说了，大家都懂的。

到apache官网下载axis2http://axis.apache.org/axis2/java/core/download.cgi推荐下载

具体步骤：

1.新建axis2 web工程。

拷贝解压文件下lib内的jar包到工程WEB-INF下的lib文件夹内。//效果如下图，下面说明

找到解压文件的webapp文件夹，拷贝目录下的axis2-web文件到axis2工程下的WebRoot根目录。在工程的WEB-INF下新建services文件夹(名字必须是services)，在services下新建axis2文件夹(这个名字没有约束)，再在下面新建META-INF文件夹，最后在META-INF下新建services.xml文件，内容如下：

<service name="axis2" scope="application" targetNamespace="http://quickstart.samples/">
    <description>
        Stock Quote 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>
    <schema schemaNamespace="http://quickstart.samples/xsd"/>
    <parameter name="ServiceClass">com.jhb.TestAxis2</parameter>
</service>

ps:com.jhb.TestAxis2是自己建立的java类，下面说明。

在web.xml文件内增加如下内容：

<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>

新建java类TestAxis2(包名是com.jhb)，与<parameter name="ServiceClass">com.jhb.TestAxis2</parameter>里的内容一致。

在TestAxis2内提供一个方法：如下

public String testHello(String name){
return name;
}

然后就是部署启动tomcat服务器。在地址栏里输入：http://localhost:8080/axis2/services/listServices回车/* axis2是工程名*/

出现如下界面说明启动成功。

图片中的axis2超链接是services.xml文件内的name名。testHello是是提供的方法名。点击axis2链接，进入一个页面，链接地址为http://localhost:8080/axis2/services/axis2?wsdl

网页内容为标准的xml文件内容。如下：

下面新建解析这个webservices的工程。

新建工程名为client的工程。添加jar包到classpath内（和上面一样）。新建一个Util类。内容如下。

i

mport org.apache.axis.wsdl.WSDL2Java;


public class Util {


public static void main(String[] args) {
String [] s = new String[]{
"-u","http://localhost:8080/axis2/services/axis2?wsdl","-o","client","-S","false"
};
/*
-u是地址，就是上面点击链接生成的URL，-o是一会要输出的文件夹名字。
*/
WSDL2Java.main(s);

}
}

运行这个main函数，刷新工程，会发现在工程下多了一个client文件夹。展开client文件夹，复制samples到src下。如下图

在cn.jhb包下新建Test类。内容如下：

public class Test {


public static void main(String[] args) {
try {
//URL内的地址是刚才生成的，即上面的
- //<wsdl:port name="axis2HttpSoap11Endpoint" binding="axis2:axis2Soap11Binding">
  //<soap:address location="http://localhost:8080/axis2/services/axis2.axis2HttpSoap11Endpoint/" />
  //</wsdl:port>
- //<wsdl:port name="axis2HttpSoap12Endpoint" binding="axis2:axis2Soap12Binding">
  //<soap12:address location="http://localhost:8080/axis2/services/axis2.axis2HttpSoap12Endpoint/" />
//  </wsdl:port>
- //<wsdl:port name="axis2HttpEndpoint" binding="axis2:axis2HttpBinding">
  ///<http:address location="http://localhost:8080/axis2/services/axis2.axis2HttpEndpoint/" />
 // </wsdl:port>
//提供了三个地址，任选一个即可。
Axis2Soap12BindingStub stub = new Axis2Soap12BindingStub(new URL("http://localhost:8080/axis2/services/axis2.axis2HttpSoap12Endpoint/"),null);
String result = stub.testHello(" ni hao webservices");
System.out.println(result);
} catch (AxisFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

运行这个main函数，发现在控制台输出ni hao webservices。

是不是觉得跨平台，跨项目，甚至跨语言编程不那么难了？具体细节自己找资料看吧。
