Spring Microservices - Terminals Pooling

Client-Server Microservice application demonstrating terminal pooling

Build

What you’ll need

• JDK 1.8 or later
• Maven 3.5+

1. Run mvn clean package
2. Run Server java -jar -Dspring.config.additional-location=server.properties terminal-server/target/terminal-server-0.0.1-SNAPSHOT.jar
3. Run client java -jar -Dspring.config.additional-location=client.properties terminal-client/target/terminal-client-0.0.1-SNAPSHOT.jar

• client|server.properties only needed to override defaults

Test

curl -X PUT http://localhost:5000/v1/terminal/client -H 'Content-Type: application/json'

Notes

1. Corner case where client requests terminalId but fails to make processing for that terminal? This could lead to a denial of service. Can be easily ameliorated with a LRU cache where terminals must be used within certain periods otherwise terminal is set to open again fixed in #1
