Java code for RabbitMQ tutorials

Here you can find the Java code examples from RabbitMQ tutorials.

To successfully use the examples you will need a RabbitMQ node running locally.

Requirements

You'll need to download the following JAR files from Maven Central:

For example, with wget:

wget https://repo1.maven.org/maven2/com/rabbitmq/amqp-client/5.6.0/amqp-client-5.6.0.jar
wget https://repo1.maven.org/maven2/org/slf4j/slf4j-api/1.7.25/slf4j-api-1.7.25.jar
wget https://repo1.maven.org/maven2/org/slf4j/slf4j-simple/1.7.25/slf4j-simple-1.7.25.jar

Copy those files in your working directory, along the tutorials Java files.

To compile you only need the Rabbitmq Java client jar on the classpath. To run them you'll need all the dependencies, see examples below.

You can set an environment variable for the jar files on the classpath e.g.

export CP=.:amqp-client-5.6.0.jar:slf4j-api-1.7.25.jar:slf4j-simple-1.7.25.jar
java -cp $CP Send

On Windows, use a semicolon instead of a colon to separate items in the classpath:

set CP=.;amqp-client-5.6.0.jar;slf4j-api-1.7.25.jar;slf4j-simple-1.7.25.jar
java -cp %CP% Send

Code

Tutorial one: "Hello World!":

javac -cp amqp-client-5.6.0.jar Send.java Recv.java

# terminal tab 1
java -cp .:amqp-client-5.6.0.jar:slf4j-api-1.7.25.jar:slf4j-simple-1.7.25.jar Recv

# terminal tab 2
java -cp .:amqp-client-5.6.0.jar:slf4j-api-1.7.25.jar:slf4j-simple-1.7.25.jar Send

Tutorial two: Work Queues:

javac -cp amqp-client-5.6.0.jar NewTask.java Worker.java

# terminal tab 1
java -cp $CP NewTask

# terminal tab 2
java -cp $CP Worker

Tutorial three: Publish/Subscribe

javac -cp amqp-client-5.6.0.jar EmitLog.java ReceiveLogs.java

# terminal tab 1
java -cp $CP ReceiveLogs

# terminal tab 2
java -cp $CP EmitLog
