Appendix D: Migrating from Moduliths

  • o.m.model.Modules has been renamed to o.s.m.model.ApplicationModulesspring-doc.cn

  • o.m.model.ModuleDetectionStrategy has been renamed to o.s.m.model.ApplicationModuleDetectionStrategyspring-doc.cn

  • @o.m.test.ModuleTest has been renamed to @o.s.m.test.ApplicationModuleTestspring-doc.cn

  • o.m.docs.Documenter.Options has been renamed to o.s.m.docs.Documenter.DiagramOptionsspring-doc.cn

  • The diagram style of component diagrams now defaults to DiagramStyle.C4 (override by calling DiagramOptions.withStyle(DiagramStyle.UML))spring-doc.cn

  • The module canvas hides non exposed types by default. To include application-module-internal types in the canvas, configure CanvasOptions to ….revealInternals().spring-doc.cn

  • The output folder for component diagrams and application module canvases has moved from moduliths-docs to spring-modulith-docs located in your build’s target folder (such as target for Maven).spring-doc.cn
