使用axis创建调用 wsdl 形式的 webservice的方法

1.下载AXIS2类库，AXIS2是目前java调用webservice的一个主要方法（由于更新较频繁，请自行google/baidu该类库的网址）

2.配置一个?server-config.wsdd 文件，文件内容如下：

<?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="sendMultiRefs" value="true"/>?
<parameter name="disablePrettyXML" value="true"/>?
<parameter name="dotNetSoapEncFix" value="true"/>?
<parameter name="enableNamespacePrefixOptimization" value="false"/>?
<parameter name="sendXMLDeclaration" value="true"/>?
<parameter name="sendXsiTypes" value="true"/>?
<parameter name="attachments.implementation" value="org.apache.axis.attachments.AttachmentsImpl"/>?
</globalConfiguration>?

<handler type="java:org.apache.axis.handlers.http.URLMapper" name="URLMapper"/>?
<service name="RemindInfo" provider="java:RPC">?
<parameter name="className" value="com.excellence.platform.missive.web.axis.RemindInfoAxis"/>?
<parameter name="scope" value="request"/>
<parameter name="allowedMethods" value="*"/>
<messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>?
</service>?
<transport name="http">?
<requestFlow>?
<handler type="URLMapper"/>?
</requestFlow>?
</transport>?
</deployment>?

注：该文件是在什么时候被加载的呢,是在下面的web.xml文件中被加载的。

详细分析是：

? ?在 web.xml

???? <servlet>
???? ??? <servlet-name>axis</servlet-name>
???? ??? <servlet-class>
???? ??? ??? org.apache.axis.transport.http.AxisServlet
???? ??? </servlet-class>
???? ??? <load-on-startup>1</load-on-startup>
???? </servlet>

上面这个只是很普通的servlet

但它是如何跟 server-config.wsdd关联起来的呢？

源码显示 AxisServlet extends AxisServletBase

在 AxisServlet .init()-->getEngine(),? getEngine() 在AxisServletBase 中，getEngine()-->getEngineEnvironment(servlet)-->EngineConfigurationFactoryFinder( 在该类装载了org.apache.axis.configuration.EngineConfigurationFactoryServlet) -->EngineConfigurationFactoryServlet(该类设置了server-config.wsdd) -->EngineConfigurationFactoryDefault

这就是web.xml加载server-config.wsdd过程，同样可以找到client-config.wsdd也是在EngineConfigurationFactoryDefault以硬代码形式存在。

应该是可以更改? server-config.wsdd?? 为别的 xxxx.wsdd??? 因为它的代码是这样处理的

???? ServletContext ctx = cfg.getServletContext();

???? String configFile = cfg.getInitParameter(OPTION_SERVER_CONFIG_FILE);
???? ??? if (configFile == null)
???? ??? configFile =??AxisProperties.getProperty(OPTION_SERVER_CONFIG_FILE);
??????? if (configFile == null) {
??????????? configFile = SERVER_CONFIG_FILE;

???? ? ? ?}

???? 其中

public static final String OPTION_CLIENT_CONFIG_FILE = "axis.ClientConfigFile";

public static final String OPTION_SERVER_CONFIG_FILE = "axis.ServerConfigFile";

protected static final String CLIENT_CONFIG_FILE = "client-config.wsdd";
protected static final String SERVER_CONFIG_FILE = "server- ??? config.wsdd";

3.在web.xml配置文件中配置如下信息：

<servlet>
??? <servlet-name>AxisServlet</servlet-name>
??? <display-name>Apache-Axis Servlet</display-name>
??? <servlet-class>
??? org.apache.axis.transport.http.AxisServlet
??? </servlet-class>
</servlet>
<servlet-mapping>
??? <servlet-name>AxisServlet</servlet-name>
??? <url-pattern>/servlet/AxisServlet</url-pattern>
</servlet-mapping>
<servlet-mapping>
??? <servlet-name>AxisServlet</servlet-name>
??? <url-pattern>*.jws</url-pattern>
</servlet-mapping>
<servlet-mapping>
??? <servlet-name>AxisServlet</servlet-name>
??? <url-pattern>/services/*</url-pattern>
</servlet-mapping>

4.然后就写个service类，如下：

???? public class RemindInfoAxis
???? {
??? ??? public Integer getInt(){
??? ??? ??? return new Integer(11312);
??? ??? }
???? }

5.然后就可以写个测试类，如下：

public class Test { ??? public static void main(String[] args) ??? { ??? ??? try{ ??? ??? String endpoint = "http://ip:port/missive/services/RemindInfo"; ??? ??? String functionName = "getInt"; ??? ??? Service service = new Service();? ??? ??? Call call = (Call) service.createCall();// 通过service创建call对象? ??? ??? call.setTargetEndpointAddress(new java.net.URL(endpoint));? ??? ??? call.setOperationName(functionName);? ??? ??? Integer ret = (Integer) call.invoke(new Object[] {});? ??? ??? ??? System.out.println(ret);? ??? ??? }catch(Exception e){ ??? ??? ??? e.printStackTrace(); ??? ??? } ??? } }
