Axis2是全新設(shè)計(jì)的，在2004年的“Axis峰會(huì)”上，大家決定采用新的架構(gòu)來(lái)讓Axis更加的富有彈性，更有效率，并且更加的可配置。Axis2現(xiàn)在具有的一些feature: Speed Low memory foot PRint AXIOM - AXis Object Model Hot Deployment Asynchronous Web Services MEP Support - Message Exchange Patterns Flexibility Stability Component-oriented deployment Transport framework WSDL support
有些feature現(xiàn)在看不懂，還是先動(dòng)手做一下，感性熟悉一下吧
第一步：下載AXIS2。http://ws.apache.org/axis2/download.cgi。很有趣，在apache的Web Service 的Project目錄下面還看不到AXIS2。要下那個(gè)binary的版本，因?yàn)槔锩嬗欣獭?br /> 第二步：Copy axis2.war到$TOMCAT_HOME/webapps目錄下面。Tomcat似乎只能用JDK1.4，我在JDK1.5 用不出來(lái)。
第三步：打開(kāi) http://localhost:8080/axis2，就可以看到axis2的Welcome頁(yè)面了。點(diǎn)一下Validate 和Services，看是不是都沒(méi)有錯(cuò)誤。都沒(méi)有錯(cuò)誤的話，就表示deploy成功了。那個(gè)adminstration頁(yè)面可以通過(guò)上傳文件來(lái)hot deploy Web service，可以用來(lái)remote deploy。
public class MyService { public OMElement echo(OMElement element) throws xmlStreamException { //Praparing the OMElement so that it can be attached to another OM Tree. //First the OMElement should be completely build in case it is not fully built and still //some of the xml is in the stream. element.build(); //Secondly the OMElement should be detached from the current OMTree so that it can be attached //some other OM Tree. Once detached the OmTree will remove its connections to this OMElement. element.detach(); return element; }
public void ping(OMElement element) throws XMLStreamException { //Do some processing } public void pingF(OMElement element) throws AxisFault{ throw new AxisFault("Fault being thrown"); } }
看得出來(lái)，函數(shù)統(tǒng)一使用OMElement作為參數(shù)。在META-INF目錄下面有個(gè)services.xml文件： <service name="MyService"> <description> This is a sample Web Service with two Operations,echo and ping. </description> <parameter name="ServiceClass" locked="false">userguide.example1.MyService</parameter> <operation name="echo"> <messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/> </operation> <operation name="ping"> <messageReceiver class="org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver"/> </operation> </service> 呵呵，也很簡(jiǎn)單嘛。有返回值的就用RawXMLINOutMessageReceiver，沒(méi)返回值的就用RawXMLINOnlyMessageReceiver。把它們編譯(要把a(bǔ)xis2的jar寫(xiě)到classpath里去)打包壓到 MyService.aar，包里文件目錄如下： .//META-INF/services.xml ./userguide/example1/MyService.class 把MyService.aar拷貝到$TOMCAT_HOME/webapps/axis2/WEB-INF/services，然后去點(diǎn)一下http://localhost:8080/axis2頁(yè)面上的Services，也就是http://localhost:8080/axis2/listServices.jsp，就可以看到MyService已經(jīng)被列出來(lái)了。
