activiti 基础搭建

首先在eclipse内添加activiti的插件，https://blog.csdn.net/qq_22701869/article/details/79537971

1.创建一个maven的java工程
2.在pom文件内导入下面的包

<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">

    <slf4j.version>1.7.7</slf4j.version>
    <log4j.version>1.2.17</log4j.version>
  </properties>

  <dependencies>

      <scope>test</scope>
    </dependency>

        </dependency>
  </dependencies>

</project>

　　3.在resources下面创建activiti.cfg.xml文件

<beans xmlns="http://www.springframework.org/schema/beans"
       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">

  <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">

    <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/activity" />
    <property name="jdbcDriver" value="com.mysql.jdbc.Driver" />
    <property name="jdbcUsername" value="root" />
    <property name="jdbcPassword" value="root" />

    <property name="databaseSchemaUpdate" value="true" />

  </bean>

</beans>

　　是通过spring初始化创建流程引擎

4.加入日志文件  在resources下

log4j.rootLogger = debug,stdout,D,E

log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n

log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = C://logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =C://logs/error.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

　　

接下来就可以通过junit创建测试类进行测试了。

在resources下面创建helloworld.bpmn文件，然后到eclipse的设置内设置保存bpmn文件自动生成图片

package acticvity;

import java.util.List;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.TaskService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.junit.Test;

public class ActivitiTest {

	/**
	 * 发布流程
	 */
	@Test
	public void deployProcess() {
		RepositoryService repositoryService = ProcessEngines.getDefaultProcessEngine()
				.getRepositoryService();
		Deployment deployment = repositoryService.createDeployment().name("Hello流程名字")
		.addClasspathResource("helloworld.bpmn")
		.addClasspathResource("helloworld.png")
		.deploy();
		System.out.println(deployment.getId() + "\t" + deployment.getName());
	}

	/**
	 * 启动任务
	 */
	@Test
	public void startProcess() {
		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
		ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceByKey("helloWorld");
		System.out.println(processInstance.getId() + "\t" + processInstance.getActivityId());
	}

	/**
	 * 查询我的任务
	 */
	@Test
	public void queryMyTask() {
		String assignee = "张三";
		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
		List<Task> list = processEngine.getTaskService().createTaskQuery()//创建任务查询对象
			.taskAssignee(assignee)//指定个人任务办理人
			.list();
		if (list != null && list.size() > 0) {
			for (Task task : list) {
				System.out.println(task.getAssignee() +"\t"+ task.getId() +"\t"+ task.getName());
			}
		}

	}

	/**
	 * 完成任务
	 */
	@Test
	public void completeTask() {
		String taskId = "104";
		ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
		TaskService taskService = processEngine.getTaskService();
		taskService.complete(taskId);
		System.out.println("任务已完成");
		System.out.println("######################");
	}
}
