This is simple demonstration on message processing using Esper, Sping and JMS(java message service).

Simple project that illustrates the use of the Esper Complex Event Processing Engine. Purposefully left Unit Tests out to reduce size of code.

When the demo runs it will just simulate sending random temperature events through the processing engine. It will print debug messages to the console when it detects a sequence of events matching any of the 3 criteria statements we have defined (Critical, Warning, Monitor).

To generate input data, JMS(ActivMQ) is used as a remote event provider.

You will need Maven installed and working.

It is suggested to using the IDE of Intelij IDEA to run the project quickly.

The component of Apache ActiveMQ is consisted of the project. So it is needed to download the Apache ActiveMQ, unzip it and double click the file of activemq.bat under apache-activemq-5.15.0\bin\win64 path.(Don't worry about the installation of Apache ActiveMQ, it is very simple actually.)

Before you run the demo, start the ActiveMQ service please.

To run demo:

• method 1:

1. Open a terminal window

2. Navigate to the root directory of the project (where the pom.xml is)

3. 'mvn clean install' (this will compile and build the project)

4. 'mvn exec:java' (this will start running the demo - sending random temperature events)

• method 2:

1. Use Git URL. copy https://github.com/liangyihuai/Esper4SpingJMS.git

2. build a IDEA project by using above URL.
