For Cobol Software modernization work, it can integrate with legacy COBOL systems through HTTP endpoints, message brokers, and JDBC-based database access. Its main limitation for COBOL-specific development is that it does not provide native COBOL tooling, so COBOL code still needs separate handling and bridging.
- +Auto-configuration accelerates bootstrapping of new Java microservices
- +Spring MVC and WebFlux support REST APIs with consistent request handling
- +Strong integration options for legacy backends via HTTP and JDBC
- –Requires separate COBOL toolchains since COBOL development is not native
- –Complex Spring dependency graphs can slow troubleshooting in large apps
- –Operational tuning for JVM performance adds setup overhead
