Dapr Bindings (HTTP)

In this quickstart, you'll create a microservice to demonstrate Dapr's bindings API to work with external systems as inputs and outputs. The service listens to input binding events from a system CRON and then outputs the contents of local data to a PostreSql output binding.

Visit this link for more information about Dapr and Bindings.

Note: This example leverages only HTTP REST. If you are looking for the example using the Dapr SDK click here.

This quickstart includes one service:

• Java service batch

Run and initialize PostgreSQL container

1. Open a new terminal, change directories to ../../db, and run the container with Docker Compose:

cd ../../db
docker compose up

Run Java service with Dapr

2. Open a new terminal window, change directories to ./batch in the quickstart directory and run:

cd ./batch
mvn clean install

3. Run the Java service app with Dapr:

dapr run --app-id batch-http --app-port 8080 --resources-path ../../../components -- java -jar target/BatchProcessingService-0.0.1-SNAPSHOT.jar
