我需要執行所有操作，例如創建quartz-2調度程序，並使用restful service僅在一個Apache駱駝上下文 上刪除。當我嘗試使用下面的代碼。每次它創建新的上下文對象。我不知道如何解決它或我需要啓動apache駱駝上下文對象。如何在每個java中使用一個apache camel上下文對象Restful services
這是我的代碼
這是我的Java RESTful服務是調用石英調度。
java Rest Services。
@Path("/remainder")
public class RemainderResource {
private static org.apache.log4j.Logger log = Logger.getLogger(RemainderResource.class);
RemainderScheduler remainderScheduler=new RemainderScheduler();
CamelContext context = new DefaultCamelContext();
@POST
@Path("/beforeday/{day}")
public void create(@PathParam("day") int day,final String userdata)
{
log.debug("the starting process of the creating the Remainder");
JSONObject data=(JSONObject) JSONSerializer.toJSON(userdata);
String cronExp=data.getString("cronExp");
remainderScheduler.create(cronExp,day,context);
}
}
這是我的java類，它是日程安排的工作。
public class RemainderScheduler {
private static org.apache.log4j.Logger log = Logger.getLogger(RemainderScheduler.class);
public void sendRemainder(int day)
{
log.debug("the starting of the sending the Remainder to user");
}
public RouteBuilder createMyRoutes(final String cronExp,final int day)
{
return new RouteBuilder()
{
@Override
public void configure() throws Exception {
log.debug("Before set schedulling");
from("quartz2://RemainderGroup/Remainder? cron="+cronExp+"&deleteJob=true&job.name='RemainderServices'").bean(new RemainderScheduler(), "sendRemainder('"+day+"')").routeId("Remainder")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
}
})
;
log.debug("after set schedulling");
}
};
}
public void stopService(CamelContext context)
{
log.debug("this is going to be stop the route");
try {
context.stopRoute("Remainder");
context.removeRoute("Remainder");
} catch (Exception e) {
e.printStackTrace();
}
}
public void create(final String cronExp,final int day,CamelContext context)
{
try
{
//this for if all ready exist then stop it.
if(context.getRoute("Remainder")!=null)
stopService(context);
log.debug("the starting of the process for creating the Remaider Services");
context.addRoutes(createMyRoutes(cronExp, day));
context.start();
log.debug("the status for removing the services is"+context.removeRoute("Remainder"));
}
catch(Exception e)
{
System.out.println(e.toString());
e.printStackTrace();
}
}
}
如果我執行上面的代碼，那麼每個java Restful請求會創建新的上下文對象。 ，它將啓動新的apache駱駝上下文對象的作業調度。如果發送請求停止路由，那麼也創建新的Apache上下文對象，所以我無法重置或停止石英2調度器。
