This service is part of the demo example on microservices patterns. This service capture text complexity metrics. It does not provide a RESTful API, but on the contrary ir provides RPC endpoints to do data processing. This processing consists on extract metircs from texts. Currently, basic metrics are implemented:
- Char count
- D-Estimate (or VOCD) diversity measurement.
- Polarity of the discourse
To implement this service, Spring Boot was used and Maven for dependency management. On the other hand, pluggins for grpc code generation where added at compile step. To start the service, you just run:
mvn clean spring-boot:run
To cleanly add grpc into the Spring Boot application GRPC Spring Boot Starter was used, as it provides flexibility to manage GRPC dependencies and add Contexts to the Spring App. In particular, with these facilities, a middleware was developed to validate authentication tokens using go-auth-microservice.
Package the sources:
mvn clean package
Then run (example):
docker build -t dpalmasan/texstat-service:latest .
Finally, to start the service:
docker run -p 6000:6000 dpalmasan/texstat-service
