ActiveJDBC example showing Many-To-Many

This example shows a typical usage of ActiveJDBC in a Many-to-Many relationship where a join table is also used to record some metadata for each relationship

Usage:

• Adjust your database connection parameters in file:

    src/main/resources/database.properties

• Execute database migrations:

    mvn db-migrator:create
    mvn db-migrator:migrate

• Build program:

    mvn clean install

• Execute:

mvn clean package  exec:java -Dexec.mainClass="activejdbc.examples.simple.Main" -Dexec.cleanupDaemonThreads=false

• Examine the output:

Line similar to this at the end:

Model: activejdbc.examples.simple.Person, table: 'people', attributes: {id=4, name=Stephen Spielberg}

Instrumentation

If you run this example from an IDE, you will need to instrument models before running. Here is how:

mvn process-classes

another way of doing the same is:

mvn activejdbc-instrumentation:instrument
