Training program

Module 1MapStruct Fundamentals: configuration and advanced mappings (annotations, processor, Maven/Gradle integration)

Dive into expert installation of MapStruct via Maven or Gradle, configure the annotation processor to generate ultra-performant implementations, perform basic mappings between entities and DTOs with exercises on real enterprise cases, explore qualifiers and injected dependencies, produce your first custom mapper with immediate IDE validation, and integrate it into an existing Spring Boot project to measure immediate productivity gains.

Module 2Complex MapStruct Mappings: relationships, conversions and inheritance (collections, nested objects, custom methods)

Master bidirectional mappings with @MappingTarget, handle one-to-many and many-to-one relationships on nested objects, implement custom conversions via @AfterMapping and Java expressions, handle polymorphic inheritance with @SubclassMapping, apply these techniques to a concrete banking microservice case, generate conditional mappers with @Condition, and optimize to avoid N+1 database queries, while producing a testable deliverable.

Module 3MapStruct Optimization and Testing: performance, best practices and deployment (profiling, Spock/JUnit, CI/CD)

Profile the performance of your MapStruct mappers with VisualVM and JMH for gains up to 80% in speed, implement exhaustive unit tests with Mockito and AssertJ on edge case scenarios, adopt best practices for maintainability in agile teams, integrate MapStruct into CI/CD pipelines with Jenkins/GitHub Actions, deploy in a Docker container with monitoring, finalize a complete ongoing project with performance report, and prepare certification of your professional skills.
