ibmstocktrader / portfolio-spring

Microservice implemented with Spring that persists stock portfolios to JDBC (such as DB2)

-------------------------------------------------------------------------------

WORK IN PROGRESS

Note: This is a work in progress Spring port of the orginal portfolio service.

-------------------------------------------------------------------------------

This service manages a stock portfolio. The data is backed by two DB2 tables, communicated with via JDBC. The following operations are available:

GET /portfolio/ - gets summary data for all portfolios

POST /portfolio/{owner} - creates a new portfolio for the specified owner

GET /portfolio/{owner} - gets details for the specified owner

PUT /portfolio/{owner} - updates the portfolio for the specified owner (by adding a stock)

DELETE /portfolio/{owner} - removes the portfolio for the specified owner

POST /portfolio/{owner}/feedback - submits feedback (to the Watson Tone Analyzer)

Build & Config.

mvn package Will produce an executable jar in the target folder.

mvn package boost:docker-build Will create a docker image portfolio-spring:latest that uses OpenLiberty to execute the application.

portfolio-spring's Issues

Add Kafka support (matching what the MP `portfolio` now does)

hey @BarDweller - when you get a chance, we should look at whether you can update your portfolio-spring to do the Kafka stuff for talking to IBM Event Streams, like portfolio now does (as requested for the FastStart and Think demos). presumably you'd use https://spring.io/projects/spring-kafka. would be another good comparison point of possible ease-of-use in Spring versus the approach you'd currently use in Java without it (which will get much better, once mpReactiveMessaging becomes available). we should be able to get to where trade-history can consume the message you'd post from Spring, just like it can the message I currently post to the stocktrader topic.
