I. Technology

- Java 1.8 - Maven 3.3.9 - Spring Tool Suite – Version 3.8.1.RELEASE - Spring Boot: 1.5.3.RELEASE

II. Overview

1. Goal

To build a Spring Boot application that helps to manage process as below: - We will create a group of persons and use Spring JPA to store their information. - Then we assign: + Check Hardware and Do Meeting to John. + Check Software and Check Firmware to David. + Write Report to Katherin. - John's tasks and David's tasks can be handled in parallel. David doesn't need to wait for any task which is assigned to John be done. - Katherin is the assignee of Write Report task only if Check Hardware, Check Software and Check Firmware are done. - After report is done, 'notification' message will be shown in the System Console.

2. Project Structure

- Process definition will be written under XML format in process/process.bpmn20.xml file. - MyService provides service methods for Controller such as: startProcess(), getTasks(), completeTask(). Those functions can be done with help of some @Autowired objects which are instances of these classes: + RepositoryService + RuntimeService + TaskService + PersonRepository - PersonRepository is an interface extends JpaRepository for implementing repository methods on Person entities. - SpringParallelActivitiApplication class contains Bean that calls MyService's creating persons method when starting the application. - MyController is a REST Controller which has request mapping methods for RESTful requests such as: /process, /tasks, /completetask. - pom.xml contains dependencies for: + Activiti Spring Boot Starter Basic, Activiti Spring Boot Starter JPA + Spring Boot Starter Web + H2 database + Groovy: scripting engine for running Script Task in process.
