How to integrate Activiti6 with SpringBoot1.5.9
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.
