创建Activiti项目详解编程语言
2023-06-13 09:20:39 时间
1.创建项目
2.导入Activiti的jar包
项目上右击创建lib文件夹
将jar包复制进lib文件夹
3.导入数据库连接jar包
4.使用代码创建Activiti用来存放流程数据的23张表
package junit;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.junit.Test;
public class TestActiviti {
/**
* 使用代码创建工作流需要的23张表
@Test
public void createTable(){
ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
//连接数据库配置
processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/activiti?useUnicode=true characterEncoding=utf8");
processEngineConfiguration.setJdbcUsername("root");
processEngineConfiguration.setJdbcPassword("******");
/**
public static final String DB_SCHEMA_UPDATE_FALSE = "false";//不能自动创建表，需要表存在
public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";//先删除表再创建表
public static final String DB_SCHEMA_UPDATE_TRUE = "true";//如果表不存在，自动创建表
processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
//工作流的核心对象，ProcessEngine对象
ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
System.out.println("processEngine:"+ processEngine);
}
5.优化使用配置文件来创建工作流需要的23张表
activiti.cfg.xml
beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"
!--
ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
//连接数据库配置
processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/activiti?useUnicode=true characterEncoding=utf8");
processEngineConfiguration.setJdbcUsername("root");
processEngineConfiguration.setJdbcPassword("******");
/**

public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";//先删除表再创建表
public static final String DB_SCHEMA_UPDATE_TRUE = "true";//如果表不存在，自动创建表
processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
bean id="processEngineConfiguration"
property name="jdbcDriver" value="com.mysql.jdbc.Driver" /property

property name="jdbcUsername" value="root" /property
property name="jdbcPassword" value="******" /property
!-- 没有表创建表 --
property name="databaseSchemaUpdate" value="true" /property
/bean
/beans
log4j.properties

TestActiviti.java
package junit;

processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
//工作流的核心对象，ProcessEngine对象
ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
System.out.println("processEngine:"+ processEngine);
* 使用配置文件来创建工作流需要的23张表
@Test
public void createTable2(){
// ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
// //工作流的核心对象，ProcessEngine对象

ProcessEngine processEngine = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml").buildProcessEngine();
System.out.println("processEngine:"+ processEngine);
}
6.创建流程图

7.部署流程定义
HelloWorld.java
package com.mycom.helloWorld;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.repository.Deployment;
import org.junit.Test;
public class HelloWorld {
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
*部署流程定义
@Test
public void deploymentProcessDefinition(){
Deployment deployment = processEngine.getRepositoryService()//与流程定义和部署对象相关的Service
.createDeployment()//创建一个部署对象
.name("HelloWorld入门")//添加部署名称
.addClasspathResource("diagrams/HelloWorld.bpmn")//从classpath的资源中加载，一次只能加载一个文件
.addClasspathResource("diagrams/HelloWorld.png")
.deploy();//完成部署
System.out.println(deployment.getId());
System.out.println(deployment.getName());
}
8.启动流程实例
package com.mycom.helloWorld;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.runtime.ProcessInstance;
import org.junit.Test;
public class HelloWorld {
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
*部署流程定义
@Test
public void deploymentProcessDefinition(){
Deployment deployment = processEngine.getRepositoryService()//与流程定义和部署对象相关的Service
.createDeployment()//创建一个部署对象
.name("HelloWorld入门")//添加部署名称
.addClasspathResource("diagrams/HelloWorld.bpmn")//从classpath的资源中加载，一次只能加载一个文件
.addClasspathResource("diagrams/HelloWorld.png")
.deploy();//完成部署
System.out.println("部署ID："+deployment.getId());
System.out.println("部署名称:"+deployment.getName());
* 启动流程实例
@Test
public void startProcessInstance(){
//流程定义的key
String processDefinitionKey = "HelloWorld";
ProcessInstance processInstance = processEngine.getRuntimeService()//与正在执行的流程实例和执行对象相关的Service
.startProcessInstanceByKey(processDefinitionKey);//使用流程定义的key启动流程实例，key对应HelloWorld.bpmn文件中的ID的属性值,使用key值启动，默认是按照最新版本的流程定义启动
System.out.println("流程实例ID:"+processInstance.getId());//流程实例ID
System.out.println("流程定义ID:"+processInstance.getProcessDefinitionId());//流程定义ID
}
9. 查询当前人的个人任务
package com.mycom.helloWorld;
import java.util.List;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.runtime.ProcessInstance;

.addClasspathResource("diagrams/HelloWorld.png")
.deploy();//完成部署
System.out.println("部署ID："+deployment.getId());
System.out.println("部署名称:"+deployment.getName());
* 启动流程实例
@Test
public void startProcessInstance(){
//流程定义的key
String processDefinitionKey = "HelloWorld";
ProcessInstance processInstance = processEngine.getRuntimeService()//与正在执行的流程实例和执行对象相关的Service
.startProcessInstanceByKey(processDefinitionKey);//使用流程定义的key启动流程实例，key对应HelloWorld.bpmn文件中的ID的属性值,使用key值启动，默认是按照最新版本的流程定义启动
System.out.println("流程实例ID:"+processInstance.getId());//流程实例ID
System.out.println("流程定义ID:"+processInstance.getProcessDefinitionId());//流程定义ID
* 查询当前人的个人任务
@Test
public void findMyPersonalTask(){
String assignee = "张三";
List Task list = processEngine.getTaskService()//与正在执行任务相关的Service
.createTaskQuery()//创建任务查询对象
.taskAssignee(assignee)//指定个人任务查询，指定办理人
.list();
if(list!=null list.size() 0){
for(Task task:list){
System.out.println("任务ID："+task.getId());
System.out.println("任务名称："+task.getName());
System.out.println("任务创建时间："+task.getCreateTime());
System.out.println("任务办理人："+task.getAssignee());
System.out.println("流程实例ID："+task.getProcessInstanceId());
System.out.println("执行对象ID："+task.getExecutionId());
System.out.println("流程定义ID："+task.getProcessDefinitionId());
}
