This project is an application skeleton for a Facebook Messenger Chatbot using Java, Spring Boot, and messenger4j. You can use it to quickly bootstrap your chatbot projects and write your first Messenger Chatbot within minutes.

It's a pre-configured Maven project containing a sample chatbot application and all required dependencies.

The sample application is a port of the official Messenger Platform NodeJS Showcase. For information on how to setup your chatbot you can follow along with the Setup Guide.

• Git
• JDK 8 or later
• Maven 3.0 or later

To get started you can simply clone this repository using git:

git clone https://github.com/messenger4j/messenger4j-spring-boot-quickstart-template.git
cd messenger4j-spring-boot-quickstart-template

In order to get your chatbot working you have to provide the following settings:

messenger4j.appSecret = ${MESSENGER_APP_SECRET}
messenger4j.verifyToken = ${MESSENGER_VERIFY_TOKEN}
messenger4j.pageAccessToken = ${MESSENGER_PAGE_ACCESS_TOKEN}

The configuration is located in src/resources/application.properties.

With the default configuration you can provide these values through the environment variables MESSENGER_APP_SECRET, MESSENGER_VERIFY_TOKEN, and MESSENGER_PAGE_ACCESS_TOKEN.

You can run the application from the command line using:

mvn spring-boot:run

Or you can build a single executable JAR file that contains all the necessary dependencies, classes, and resources with:

mvn clean package

Then you can run the JAR file with:

java -jar target/*.jar

Instead of mvn you can also use the maven-wrapper ./mvnw to ensure you have everything necessary to run the Maven build.
