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">

</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("######################");
}
}
