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

  - UHIMSEventsServiceImpl.java, a Java consumer used for UHIMS Events
  - RabbitMqConnector.java, a Java producer for a SECE exchange

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,
);

Use sample-RabbitMessaging-code as a template for your app.
