使用SOAPMonitor

能够监视SOAP消息对于Web Service开发者来说很重要，Axis2自带了这个功能，但是出于安全考虑，Axis2默认状态下并没有启用这个功能。想要启用它，需要下列步骤：

1、找到axis2.xml文件。它位于<CATALINA_HOME>/webapps/axis2/WEB-INF/conf目录下，添加下面一句话：

class="xml"><module ref="soapmonitor"/>

2、axis2中定义自己的‘soapmonitorPhase’

class="xml">   <phaseOrder type="inflow">
        <!--System pre defined phases-->
        <phase name="TransportIn"/>
        <phase name="PreDispatch"/>
        <phase name="Dispatch" class="org.apache.axis2.engine.DispatchPhase">
            <handler name="AddressingBasedDispatcher"
                     class="org.apache.axis2.dispatchers.AddressingBasedDispatcher">
                <order phase="Dispatch"/>
            </handler>
            <handler name="RequestURIBasedDispatcher"
                     class="org.apache.axis2.dispatchers.RequestURIBasedDispatcher">
                <order phase="Dispatch"/>
            </handler>
            <handler name="SOAPActionBasedDispatcher"
                     class="org.apache.axis2.dispatchers.SOAPActionBasedDispatcher">
                <order phase="Dispatch"/>
            </handler>
            <handler name="SOAPMessageBodyBasedDispatcher"
                     class="org.apache.axis2.dispatchers.SOAPMessageBodyBasedDispatcher">
                <order phase="Dispatch"/>
            </handler>
            <handler name="InstanceDispatcher"
                     class="org.apache.axis2.engine.InstanceDispatcher">
                <order phase="PostDispatch"/>
            </handler>
        </phase>
        <!--System pre defined phases-->
        <!--After Postdispatch phase module author or or service author can add any phase he want-->
        <phase name="userphase1"/>
        <phase name="soapmonitorPhase"/>
    </phaseOrder>
    <phaseOrder type="outflow">
        <!--user can add his own phases to this area-->
        <phase name="userphase1"/>
        <phase name="soapmonitorPhase"/>
        <!--system predefined phase-->
        <!--these phase will run irrespective of the service-->
        <phase name="PolicyDetermination"/>
        <phase name="MessageOut"/>
    </phaseOrder>
    <phaseOrder type="INfaultflow">
        <!--user can add his own phases to this area-->
        <phase name="userphase1"/>
        <phase name="soapmonitorPhase"/>
    </phaseOrder>
    <phaseOrder type="Outfaultflow">
        <!--user can add his own phases to this area-->
        <phase name="userphase1"/>
        <phase name="soapmonitorPhase"/>
        <phase name="PolicyDetermination"/>
        <phase name="MessageOut"/>
    </phaseOrder>

3、在web.xml中加入

class="xml">    <servlet>
       <servlet-name>SOAPMonitorService</servlet-name>
       <display-name>SOAPMonitorService</display-name>
       <servlet-class>
         org.apache.axis2.soapmonitor.servlet.SOAPMonitorService
       </servlet-class>
       <init-param>
          <param-name>SOAPMonitorPort</param-name>
          <param-value>5001</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>SOAPMonitorService</servlet-name>
        <url-pattern>/SOAPMonitor</url-pattern>
    </servlet-mapping>

4、<CATALINA_HOME>/webapps/axis2/WEB-INF/lib下有个jar文件叫做soapmonitor-1.4.1.jar，把它解压到axis2根目录<CATALINA_HOME>/webapps/axis2。

5、浏览器的地址是：http://localhost:8080/axis2/SOAPMonitor

6、在这里，我们需要注意一个配置问题，如果tomcat下有多个axis应用，设置了多个SOAPmonitor，我们则需要更改SOAPmonitor的端口（axis默认配置的是5001），否则会产生冲突，运行SOAPmonitor时会无法启动，提示the soap monitor is unable to communcate with the server，解决方法如下：

打开C:/Tomcat5/webapps/axis/WEB-INF目录下的web.xml，找到

class="xml"><servlet>
      <servlet-name>SOAPMonitorService</servlet-name>
      <display-name>SOAPMonitorService</display-name>
      <servlet-class>
          org.apache.axis.monitor.SOAPMonitorService
      </servlet-class>
      <init-param>
        <param-name>SOAPMonitorPort</param-name>
        <param-value>5001</param-value>
      </init-param>
      <load-on-startup>100</load-on-startup>
</servlet>

这段，将其中的5001改成5002，依此类推。
