java 执行 activiti 第一个例子
说明：自定义一个简单流程，然后在main中直接通过控制台输入信息然后控制流程。
1、创建一个maven项目 引入依赖：
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.10.RELEASE</version>
</parent>
<groupId>com.jy.activiti</groupId>

</project>
2、添加流程模板文件：
MyProcess.bpmn

也可以自己创建模板文件，参考：
https://blog.csdn.net/java_study_/article/details/104904861
3、创建一个类MyActiviti，直接main方法测试：
package com.jy.main;
import com.google.common.collect.Maps;
import org.activiti.engine.*;
import org.activiti.engine.form.FormProperty;
import org.activiti.engine.form.TaskFormData;
import org.activiti.engine.impl.form.DateFormType;
import org.activiti.engine.impl.form.StringFormType;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.ProcessDefinition;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.*;
public class MyActiviti {
private static final Logger logger = LoggerFactory.getLogger(DemoMain1.class);
private static String filePath = "MyProcess.bpmn";
public static void main(String[] args) throws ParseException {
logger.info("启动程序------------");
//1创建流程引擎
ProcessEngine processEngine = ProcessEngineConfiguration
.createStandaloneInMemProcessEngineConfiguration()
.buildProcessEngine();
logger.info("流程引擎名称[{}],版本[{}]",processEngine.getName(),processEngine.VERSION);
//2、部署流程定义文件
Deployment deploy = processEngine.getRepositoryService().createDeployment()
.addClasspathResource(filePath).deploy();
ProcessDefinition processDefinition = processEngine.getRepositoryService()
.createProcessDefinitionQuery()
.deploymentId(deploy.getId())
.singleResult();
//3、启动流程
ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceById(processDefinition.getId());
logger.info("流程启动{}",processInstance.getProcessDefinitionKey());
//4.处理流程任务
Scanner scanner = new Scanner(System.in);
while (processInstance!=null&&!processInstance.isEnded()){
TaskService taskService = processEngine.getTaskService();
List<Task> list = taskService.createTaskQuery().list();
for (Task task : list){
TaskFormData taskFormData = processEngine.getFormService().getTaskFormData(task.getId());
List<FormProperty> formProperties = taskFormData.getFormProperties();
Map<String,Object> map = Maps.newHashMap();
for (FormProperty pro:formProperties) {
String line = null;
if(StringFormType.class.isInstance(pro.getType())){
logger.info("请输入：{}",pro.getName());
line = scanner.nextLine();
logger.info("您输入的是：{}",line);
map.put(pro.getId(),line);
}else if (DateFormType.class.isInstance(pro.getType())){
logger.info("请输入：{}，格式{yyyy-MM-dd}",pro.getName());
line = scanner.nextLine();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyy-MM-dd");
Date date = simpleDateFormat.parse(line);
map.put(pro.getId(),date);
}else{
logger.info("类型暂不支持{}",pro.getType());
}
}
taskService.complete(task.getId(),map);
//更新任务节点
processInstance = processEngine
.getRuntimeService()
.createProcessInstanceQuery()
.processInstanceId(processInstance.getId())
.singleResult();
}
}
logger.info("结束程序------------");
}
}
注意：有的地方方法，部署流程定义文件时直接改为.xml文件，当时我也使用过，但不行，只能使用
.bpmn文件。
效果图：
