10分鐘輕鬆搞定SpringBoot整合Activiti6教程

第一步在專案pom.xml檔案中新增所需依賴

	</build>


</project>

第二步:編寫示例介面和介面實現類

介面類(ActivityConsumerService.java)

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("/test")  
public interface ActivityConsumerService {  
    /** 
     * 流程demo 
     * @return 
     */  
    @RequestMapping(value="/activitiDemo",method=RequestMethod.GET)  
    public boolean startActivityDemo();  
      
}  

介面實現類(ActivityConsumerServiceImpl.java)

package com.springboot.demo.service.impl;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

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.activiti.engine.task.TaskQuery;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.springboot.demo.service.ActivityConsumerService;

@Service("activityService")  
public class ActivityConsumerServiceImpl implements ActivityConsumerService {  
  
    @Autowired  
    private RuntimeService runtimeService;  
    @Autowired  
    private TaskService taskService;  
    
    @Autowired
    private RepositoryService repositoryService;
      
    @Override  
    public boolean startActivityDemo() {  
        System.out.println("method startActivityDemo begin....");  
        
        System.out.println( "呼叫流程儲存服務,查詢部署數量:"
                + repositoryService.createDeploymentQuery().count());
        

      
        Map<String,Object> map = new HashMap<String,Object>();  
        map.put("apply","zhangsan");  
        map.put("approve","lisi");  
        
        //流程啟動  
        ExecutionEntity pi1 = (ExecutionEntity) runtimeService.startProcessInstanceByKey("leave",map);  
       
        List<Task> tq=taskService.createTaskQuery().taskAssignee("zhangsan").list();
        System.out.println(tq.size());
        String assignee = "zhangsan";//當前任務辦理人  
        List<Task> tasks = taskService//與任務相關的Service  
                .createTaskQuery()//建立一個任務查詢物件  
                .taskAssignee(assignee)  
                .list();  
        if(tasks !=null && tasks.size()>0){  
            for(Task task:tasks){  
                System.out.println("任務ID:"+task.getId());  
                System.out.println("任務的辦理人:"+task.getAssignee());  
                System.out.println("任務名稱:"+task.getName());  
                System.out.println("任務的建立時間:"+task.getCreateTime());  

                System.out.println("流程例項ID:"+task.getProcessInstanceId());
                System.out.println("#####################################");  
            }  
        }  
     
        System.out.println("method startActivityDemo end....");  
        return false;  
    }  
}  

第三步:在src/main/java/resources目錄下新建processes目錄,並在該目錄下新增一個業務流程檔案

MyProcess.bpmn:

</definitions>

專案目錄結構如下圖:


第四步:在mysql資料庫伺服器增加資料庫:activiti-demo

第五步:設定application.properties配置自己應用的相關資訊

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/activiti-demo?characterEncoding=utf8&useSSL=true
spring.datasource.username=root
spring.datasource.password=ROOT
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.show-sql=true
server.port=8081
server.context-path=/
server.session.timeout=10
server.tomcat.uri-encoding=UTF-8

第六步:啟動應用後,在瀏覽器位址列輸入訪問地址:

http://localhost:8081/test/activitiDemo

第七步:看控制後臺輸出結果如下圖,即代表成功。
