Jbpm4.3 學習筆記（一）

 

 

1.       jbpm建立資料庫

package com.langsi.jbpm;

 

import org.jbpm.api.Configuration;

import org.jbpm.api.ProcessEngine;

 

public class Test1 {

       /**

        * 建立JBPM資料庫表

        */

       public static void main(String[] args) {

             

              Configuration configuration = new Configuration();

              //建立流程引擎

              @SuppressWarnings("unused")

              ProcessEngine processEngine = configuration.buildProcessEngine();

       }

 

}

 

2． 流程一first.jpdl.xml

2.1 流程定義檔案

<?xml version="1.0" encoding="UTF-8"?>

<process name="first" xmlns="http://jbpm.org/4.3/jpdl">

   <start g="222,38,48,48" name="start1">

      <transition g="-59,-17" name="to state1" to="state1"/>

   </start>

   <state g="197,174,92,52" name="state1">

      <transition name="to end1" to="end1" g="-47,-17"/>

   </state>

   <end g="220,350,48,48" name="end1"/>

</process>

2.2 流程圖first.png

2.3 部署程式

package com.langsi.jbpm;

 

import org.jbpm.api.Configuration;

import org.jbpm.api.NewDeployment;

import org.jbpm.api.ProcessEngine;

import org.jbpm.api.RepositoryService;

 

public class Test2 {

 

       /**

        * 完成流程的部署功能

        */

       public static void main(String[] args) {

              //1、建立JBPM配置物件

              Configuration configuration = new Configuration();

              //2、建立流程引擎

              ProcessEngine processEngine = configuration.buildProcessEngine();

              //3、獲得資料倉儲服務物件

              RepositoryService repositoryService =  processEngine.getRepositoryService();

              //4、建立部署例項物件

              NewDeployment newDeployment  = repositoryService.createDeployment();

              //5、從類路徑下面增加流程部署檔案到部署例項物件

              newDeployment = newDeployment.addResourceFromClasspath("first.jpdl.xml");

              //6完成流程的部署

              String processNameString = newDeployment.deploy();            

              System.out.println(processNameString);            

       }

}

 

2.4 獲取流程定義

package com.langsi.jbpm;

 

import java.util.Iterator;

import java.util.List;

 

import org.jbpm.api.Configuration;

import org.jbpm.api.NewDeployment;

import org.jbpm.api.ProcessDefinition;

import org.jbpm.api.ProcessEngine;

import org.jbpm.api.RepositoryService;

 

public class Test3 {

       /**

        * 完成流程的執行

        */

       public static void main(String[] args) {

              // 1、建立JBPM配置物件

              Configuration configuration = new Configuration();

              // 2、建立流程引擎

              ProcessEngine processEngine = configuration.buildProcessEngine();

              // 3、獲得資料倉儲服務物件

              RepositoryService repositoryService = processEngine

                            .getRepositoryService();

              // 4、建立部署例項物件

              NewDeployment newDeployment = repositoryService.createDeployment();

              // 5、從類路徑下面增加流程部署檔案到部署例項物件

              newDeployment = newDeployment

                            .addResourceFromClasspath("first.jpdl.xml");

              // 6完成流程的部署

              newDeployment.deploy();

              //7由RepositoryService建立流程定義查詢介面

              List<ProcessDefinition> list = repositoryService

                            .createProcessDefinitionQuery().list();

              for (Iterator<ProcessDefinition> iterator = list.iterator(); iterator.hasNext();) {

                     ProcessDefinition processDefinition = (ProcessDefinition) iterator

                                   .next();

                     System.out.println(processDefinition.getDeploymentId()+"---"

                                   +processDefinition.getId()+"---"+processDefinition.getName());

              }

       }

}

 

2.5 流程開始執行

package com.langsi.jbpm;

 

import org.jbpm.api.Configuration;

import org.jbpm.api.ExecutionService;

import org.jbpm.api.ProcessEngine;

import org.jbpm.api.ProcessInstance;

 

public class Test4 {

       public static void main(String[] args) {

              // 1、建立JBPM配置物件

              Configuration configuration = new Configuration();

              // 2、建立流程引擎

              ProcessEngine processEngine = configuration.buildProcessEngine();

              //3、獲得流程執行服務物件

              ExecutionService executionService = processEngine.getExecutionService();

              //4、流程執行服務物件根據流程定義執行，獲得流程例項

              ProcessInstance processInstance = executionService.startProcessInstanceByKey("first");

              System.out.println("processInstance Id " +processInstance.getId());

       }

}

 

2.6 流程執行下一步

import org.jbpm.api.RepositoryService;

 

public class Test5 {

       public static void main(String[] args) {

              //1、建立JBPM配置物件

              Configuration configuration = new Configuration();

              //2、建立流程引擎

              ProcessEngine processEngine = configuration.buildProcessEngine();

              //3、獲得資料倉儲服務物件

              RepositoryService repositoryService =  processEngine.getRepositoryService();

              //4、建立部署例項物件

              NewDeployment newDeployment  = repositoryService.createDeployment();

              //5、從類路徑下面增加流程部署檔案到部署例項物件

              newDeployment = newDeployment.addResourceFromClasspath("first.jpdl.xml");

              //6完成流程的部署

              newDeployment.deploy();

              //7、獲得流程執行服務物件

              ExecutionService executionService = processEngine.getExecutionService();

              //8、流程執行服務物件根據流程定義執行，得到流程例項

              ProcessInstance processInstance = executionService.startProcessInstanceByKey("first");

              //9、使用流程執行服務物件觸發流程例項往下一節點走,產生一個新的流程例項物件

              ProcessInstance processInstance2 = executionService.signalExecutionById(processInstance.getId());       

              System.out.println(processInstance2.isEnded());

       }

}
