From d8f1fc01551699eb75821119988e47a06b48aa41 Mon Sep 17 00:00:00 2001 From: Janne Valkealahti Date: Mon, 6 May 2019 15:23:31 +0100 Subject: [PATCH] Initial reactive action support - This first commit related to reactive action support basically changes internal logic away from original Action interface which really is just a Consumer but it originates pre jdk8 era. Reactive equivalent internally is now Function, Mono>. - Essentially actions will now get executed with a reactor chain fully. - Fix StateMachineExecutorTransit in AbstractStateMachine to be full reactive chain which were needed to get reactive actions working. This also put StateContextTests back to its original state. - Add typesafe interface ReactiveAction which simply wraps Function, Mono> and add this to transitions with actionFunction() as a concept. This will be added to states in next commits if actionFunction() as a concept works. - Polish various things and issues which were not addressed with initial reactive commit. - Disable ActionSecurityTests for now as secured Action bean now breaks because it's internally wrapped into a Function and Spring Security doesn't see it anymore. Security like this needs a bit of a overhaul which can be done later. - State do actions which are done via scheduling needs some work as now we just do a subscribe which is probably a bit wrong. There's going to be more work for scheduling so this also can be left later stages. - Relates #743 --- .../boot/support/BootStateMachineMonitor.java | 20 ++- .../statemachine/action/ActionListener.java | 9 +- .../statemachine/action/Actions.java | 22 ++- .../action/CompositeActionListener.java | 9 +- .../statemachine/action/ReactiveAction.java | 34 ++++ .../config/AbstractStateMachineFactory.java | 19 ++- .../config/ObjectStateMachineFactory.java | 18 +- .../StateMachineTransitionBuilder.java | 22 ++- .../AbstractTransitionConfigurer.java | 20 ++- .../DefaultExternalTransitionConfigurer.java | 13 +- .../DefaultInternalTransitionConfigurer.java | 13 +- .../DefaultLocalTransitionConfigurer.java | 13 +- .../configurers/DefaultStateConfigurer.java | 30 +++- .../configurers/TransitionConfigurer.java | 16 +- .../statemachine/config/model/StateData.java | 34 ++-- .../model/StateMachineComponentResolver.java | 4 +- .../config/model/TransitionData.java | 24 +-- .../monitor/AbstractStateMachineMonitor.java | 11 +- .../monitor/CompositeStateMachineMonitor.java | 12 +- .../monitor/StateMachineMonitor.java | 10 +- .../state/AbstractSimpleState.java | 37 +++-- .../statemachine/state/AbstractState.java | 90 +++++----- .../statemachine/state/EnumState.java | 24 ++- .../statemachine/state/ObjectState.java | 61 +++---- .../statemachine/state/RegionState.java | 35 ++-- .../statemachine/state/State.java | 7 +- .../statemachine/state/StateMachineState.java | 31 ++-- .../support/AbstractStateMachine.java | 74 +++++---- .../support/ReactiveStateMachineExecutor.java | 17 +- .../support/StateMachineObjectSupport.java | 7 +- .../AbstractExternalTransition.java | 19 ++- .../AbstractInternalTransition.java | 15 +- .../transition/AbstractLocalTransition.java | 19 ++- .../transition/AbstractTransition.java | 46 +++-- .../transition/DefaultExternalTransition.java | 19 ++- .../transition/DefaultInternalTransition.java | 17 +- .../transition/DefaultLocalTransition.java | 15 +- .../transition/InitialTransition.java | 19 ++- .../statemachine/transition/Transition.java | 13 +- .../statemachine/EnumStateMachineTests.java | 34 ++-- .../statemachine/RegionMachineTests.java | 37 +++-- .../statemachine/StateContextTests.java | 157 ++++++++---------- .../statemachine/SubStateMachineTests.java | 77 +++++---- .../action/ReactiveActionTests.java | 110 ++++++++++++ .../model/StateMachineModelFactoryTests.java | 14 +- .../docs/DocsConfigurationSampleTests9.java | 14 +- .../monitor/StateMachineMonitorTests.java | 20 ++- .../security/ActionSecurityTests.java | 4 +- .../StateContextExpressionMethodsTests.java | 7 +- .../RepositoryStateMachineModelFactory.java | 23 ++- .../uml/support/UmlModelParser.java | 64 ++++--- .../statemachine/uml/support/UmlUtils.java | 44 ++++- 52 files changed, 983 insertions(+), 540 deletions(-) create mode 100644 spring-statemachine-core/src/main/java/org/springframework/statemachine/action/ReactiveAction.java create mode 100644 spring-statemachine-core/src/test/java/org/springframework/statemachine/action/ReactiveActionTests.java diff --git a/spring-statemachine-autoconfigure/src/main/java/org/springframework/statemachine/boot/support/BootStateMachineMonitor.java b/spring-statemachine-autoconfigure/src/main/java/org/springframework/statemachine/boot/support/BootStateMachineMonitor.java index 72f4c7fb..fc1b4a42 100644 --- a/spring-statemachine-autoconfigure/src/main/java/org/springframework/statemachine/boot/support/BootStateMachineMonitor.java +++ b/spring-statemachine-autoconfigure/src/main/java/org/springframework/statemachine/boot/support/BootStateMachineMonitor.java @@ -1,5 +1,5 @@ /* - * Copyright 2016-2018 the original author or authors. + * Copyright 2016-2019 the original author or authors. * * Licensed under the Apache License, Version 2.0 (the "License");
