This article will explain in detail how SpringBoot1.5.9 integrates Activiti6. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1. Create a Maven-based SpringBoot Web project at the following address

Https://start.spring.io/

two。 Add dependent files for the project

The pom.xml file is as follows

4.0.0

Activiti.demo

Activiti-demo

1.0-SNAPSHOT

War

Activiti-demo

Spring-activiti-demo

Org.springframework.boot

Spring-boot-starter-parent

1.5.9.RELEASE

UTF-8

UTF-8

1.8

Org.springframework.boot

Spring-boot-starter-web

Org.activiti

Activiti-spring-boot-starter-basic

6.0.0

Org.springframework.boot

Spring-boot-starter-data-jpa

Org.springframework.boot

Spring-boot-starter-thymeleaf

Mysql

Mysql-connector-java

Org.springframework.boot

Spring-boot-starter-test

Org.springframework.boot

Spring-boot-maven-plugin

3. Add business process files

Create a processes directory under the src/main/java/resource directory

Create a process.bpmn file with the following contents

4. Configure the application.properties file

The configuration is as follows

Spring.datasource.driver-class-name=com.mysql.jdbc.Driver

Spring.datasource.url=jdbc:mysql://127.0.0.1:3306/activiti?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false&autoReconnect=true&failOverReadOnly=false&useUnicode=true&characterEncoding=UTF-8

Spring.datasource.username=root

Spring.datasource.password=123456

Spring.jpa.properties.hibernate.hbm2ddl.auto=update

Spring.jpa.show-sql=true

Server.port=8082

Server.context-path=/

Server.session.timeout=10

Server.tomcat.uri-encoding=UTF-8

5. Code implementation

a. Define Interfac

Package com.springboot.demo.service

Import org.springframework.web.bind.annotation.RequestMapping

Import org.springframework.web.bind.annotation.RequestMethod

Import org.springframework.web.bind.annotation.RestController

@ RestController

@ RequestMapping ("/ activityConsumerService")

Public interface ActivityConsumerService {

@ RequestMapping (value = "/ startActivityDemo", method = RequestMethod.GET)

Public boolean startActivityDemo ()

}

b. Implementation interface

Package com.springboot.demo.service.impl

Import com.springboot.demo.service.ActivityConsumerService

Import org.activiti.engine.RepositoryService

Import org.activiti.engine.RuntimeService

Import org.activiti.engine.TaskService

Import org.activiti.engine.impl.persistence.entity.ExecutionEntity

Import org.activiti.engine.task.Task

Import org.springframework.beans.factory.annotation.Autowired

Import org.springframework.stereotype.Service

Import java.util.HashMap

Import java.util.List

Import java.util.Map

/ * *

* @ ClassName ActivityConsumerServiceImpl

* @ Description TODO

* @ Author yunshuodeng

* @ Date 2019-04-29 13:28

* @ Version 1.0

* * /

@ Service ("activityService")

Public class ActivityConsumerServiceImpl implements ActivityConsumerService {

@ Autowired

Private RuntimeService runtimeService

@ Autowired

Private TaskService taskService

@ Autowired

Private RepositoryService repositoryService

@ Override

Public boolean startActivityDemo () {

/ / get the current method name

String methodName = Thread.currentThread () .getStackTrace () [1] .getMethodName ()

/ / define the task manager

String name1 = "zhangsan"

String name2 = "lisi"

System.out.println ("method" + methodName + "begin...")

/ / output number of process deployments

System.out.println ("call the process storage service to query the number of deployments" + repositoryService.createDeploymentQuery () .count ())

Map map = new HashMap ()

Map.put ("apply", name1)

Map.put ("approve", name2)

/ / process start

ExecutionEntity executionEntity = (ExecutionEntity) runtimeService.startProcessInstanceByKey ("leave", map)

/ / query the task list of name1

List taskList = taskService.createTaskQuery () .taskAssignee (name1) .list ()

/ / output the number of tasks

System.out.println (taskList.size ())

If (taskList! = null & & taskList.size () > 0) {

For (Task task: taskList) {

System.out.println ("Task ID:" + task.getId ())

System.out.println ("Task Manager:" + task.getAssignee ())

System.out.println ("Task name:" + task.getName ())

System.out.println ("Task creation time:" + task.getCreateTime ())

System.out.println ("process instance ID:" + task.getProcessDefinitionId ())

System.out.println ("- -")

}

}

System.out.println ("method" + methodName + "end...")

Return false

}

}

6. Start the service and access it at the following address

Http://localhost:8082/activityConsumerService/startActivityDemo

7. Viewing the output of the console does not report an error indicating that the integration is complete.
