You will need a RabbitMQ client to connect to the UH Message Broker.

• Java
  • Download the Java Client
  • Sample Code
    • UHIMSEventsServiceImpl.java, a Java consumer used for UHIMS Events
    • RabbitMqConnector.java, a Java producer for a SECE exchange
• Perl
  • AnyEvent::RabbitMQ
    
    • We chose it mostly because it didn't require us to install additional software.
    • We have created a module named RabbitMessaging that uses AnyEvent::RabbitMQ.
      • It is much friendlier, but probably at the expense of AnyEvent functionality.
      • Read the warning about the consume() method in the RabbitMessaging.pm source code. You may want to use the get_message() method instead.
    • To use RabbitMessaging:
      • Download our RabbitMessaging.pm module
      • Install version 1.16 of AnyEvent::RabbitMQ or the latest version
        
        • Note that that AnyEvent::RabbitMQ version 1.16 or higher already includes the following patches which we previously had to manually apply to version 1.05 of AnyEvent::RabbitMQ
        • • RabbitMQ-tls.patch to /usr/local/lib/site_perl/5../AnyEvent/RabbitMQ/RabbitMQ.pm (for TLS support)
        • The following patch was never necessary, though it is harmless if you already have it installed:
          • RabbitMQ-Channel-args.patch for /usr/local/lib/site_perl/5../AnyEvent/RabbitMQ/Channel.pm
        • AnyEvent::RabbitMQ version 1.20_21 includes our patch to support the no_ack flag for the get method.
      • Patch Net::AMQP::Common.pm and add the "l => \&unpack_long_long_integer" line as shown below.  This is necessary with our upgrade to RabbitMQ 3.11 and/or because of quorum queues.

        • my %_unpack_field_types = (
              V => sub { undef },
              S => \&unpack_long_string,
              I => \&unpack_long_integer,
              l => \&unpack_long_long_integer,
              D => sub {
                  my $input_ref = shift;
                  my $exp = unpack_octet($input_ref);
                  my $num = unpack_long_integer($input_ref);
                  $num / 10.0 ** $exp;
              },
              F => \&unpack_field_table,
              A => \&unpack_field_array,
              T => \&unpack_timestamp,
              t => \&unpack_boolean,
          );
