Test case for configuration of JMS-Apache activemq

First, create a producer.

 Public class producer {<br/> private jmstemplate; <br/> private destination topic; </P> <p>/** <br/> * Send a JMS message <br/> * @ Param XML message <br/> */<br/> Public void send (string XML) {<br/> jmstemplate. convertandsend (topic, XML); <br/>}</P> <p> Public void setjmstemplate (jmstemplate) {<br/> This. jmstemplate = jmstemplate; <br/>}</P> <p> Public void settopic (destination topic) {<br/> This. topic = topic; <br/>}< br/>}

 

Another consumer

 Public class diyconsumer implements messagelistener {<br/> private logger = logger. getlogger (this. getclass (); </P> <p> Public void onmessage (Message MSG) {<br/> system. out. println (MSG); <br/> string smsg = NULL; <br/> try {<br/> If (MSG instanceof textmessage) {<br/> smsg = (textmessage) MSG ). gettext (); <br/> logger.info ("onmessage:" + smsg ); <br/> // put the code for processing the JMS message here <br/> // convert the received message to XML Format, xmlutil readers can download a file <br/> document DOC = xmlutil. synstring2document (msgxml); <br/> If (Doc = NULL) {<br/> throw new condition entexception ("Doc is null. XML: "+ msgxml); <br/>}< br/> element root = Doc. getrootelement (); <br/> If (! "M ". equals (root. getname () {<br/> throw new condition entexception ("Doc root error. XML: "+ Doc. asxml (); <br/>}< br/> // The result is printed only. <br/> system. out. println (root. attributevalue ("T"); <br/> system. out. println (root. attributevalue ("A"); <br/> system. out. println (root. attributevalue ("St"); <br/> element Eelement = root. element ("e") <br/> // subsequent work will not be described <br/>} else {<br/> logger. error ("MSG: MSG instance Of textmessage return false! "); <Br/>}< br/>} catch (exception e) {<br/> logger. error (E + "MSG:" + smsg); <br/>}< br/>}
