Consuming Rabbit MQ messages using Eclipse on Tomcat -


i using eclipse, tomcat , rabbit mq.

i want able consume messages of queue hit queue. have managed using java class in eclipse (see below), have not been able working when deploying war file on tomcat server. 

package org.com.hello; import com.rabbitmq.client.connectionfactory; import com.rabbitmq.client.connection; import com.rabbitmq.client.channel; import com.rabbitmq.client.queueingconsumer; public class hellorecv {    public static void main(string[] argv)       throws java.io.ioexception,              java.lang.interruptedexception {     connectionfactory factory = new connectionfactory();     factory.sethost("172.24.3.53");     factory.setport(6672);     factory.setusername("user");     factory.setpassword("password");     connection connection = factory.newconnection();     channel channel = connection.createchannel();      channel.queuedeclare("q1", true, false, false, null);     system.out.println(" [*] waiting messages. exit press ctrl+c");      queueingconsumer consumer = new queueingconsumer(channel);     channel.basicconsume("q1", true, consumer);      while (true) {       queueingconsumer.delivery delivery = consumer.nextdelivery();       string message = new string(delivery.getbody());       system.out.println(" [x] received '" + message + "'");     }      } }

is there need add web.xml file , if so, should add file?

create war application using eclipse:

you can see video: https://www.youtube.com/watch?v=fk22hqz9l_m

or googling copy code inside servlet. should use init method.

an pseudo code:

    public class yourservlet extends httpservlet {        int count;        public void init(servletconfig config) throws servletexception {         super.init(config);          connectionfactory factory = new connectionfactory();          factory.sethost("172.24.3.53");         factory.setport(6672);         factory.setusername("user");         factory.setpassword("password");         connection connection = factory.newconnection();         channel channel = connection.createchannel();          channel.queuedeclare("q1", true, false, false, null);      /// shoud put consumer inside thread.     channel.basicconsume("q1", true, new defaultconsumer(){     /// here should use default consumer , not queueingconsumer because blocking      });     }   }         public void doget(httpservletrequest req, httpservletresponse res)                                 throws servletexception, ioexception {         res.setcontenttype("text/plain");         printwriter out = res.getwriter();         .....         }     }

see defaultconsumer

hope helps

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
