kotlin-spring-protobuf

Demo project to show the integration of these three technologies

Initial setup

For the first execution the protobuf file(s) need to be compiled to the target language (Java in this case). Executing the following command in the project root folder is sufficient:

./gradlew build

The protobuf classes will be generated first, followed by the kotlin sources.

Communicating with the REST endpoint

For quick demonstrations without an explicit client cURL can be used to communicate with the endpoint.

protoc --decode returns the result of the call in the protobuf text format.

Add new event

cat src/test/resources/proto.txt \
  | protoc --encode "model.DeploymentEvent" src/main/proto/deployment-event.proto \
  | curl -H "Content-Type: application/x-protobuf" -sS -XPOST http://localhost:4242/api/deployments --data-binary @- \
  | protoc --decode "model.DeploymentEvent" src/main/proto/deployment-event.proto

id: 4
target: ACCEPTANCE
technology: "Database"
product: "Oracle11"
version: "0.0.1"
status: FAILED

Get event

curl -XGET http://localhost:4242/api/deployments/4 \
  | protoc --decode "model.DeploymentEvent" src/main/proto/deployment-event.proto

id: 4
target: ACCEPTANCE
technology: "Database"
product: "Oracle11"

Find by target

curl -XGET "http://localhost:4242/api/deployments?target=ACCEPTANCE" \
  | protoc--decode "model.DeploymentEvents" src/main/proto/deployment-event.proto

deploymentEvent {
  id: 2
