Spring Boot Java applications for CICS

Create standalone, production-grade Java apps that are easy to run

By Phil Wakelin, Chris Atkinson, Ivan Hargreaves, Qin Li, Matthew Wilson

On this page

This tutorial series is designed to get you up to speed with the usage of Java and Spring Boot in CICS Liberty. Spring Boot makes it easy to create standalone, production-grade Java applications that you can just run. Spring was designed to simplify Java Enterprise Edition using plain old Java objects (POJOs) and dependency injection, and Spring Boot builds on Spring by adding components to reduce development time and configuration. Both web applications and CICS linkable Spring Boot applications are supported in CICS, and this set of tutorials and samples provide step-by-step instructions for everything you need to know to build an enterprise Java application using Spring Boot -- starting with building your first application, through to using security and transactions, integrating with Db2 using JDBC or JPA, accessing IBM MQ with JMS, and starting threads using thread concurrency.
