Flowable启动流程实例和查询任务以及完成任务
效果图
因为流程删除，所以需要

日志配置
log4j.rootLogger=DEBUG, CA
log4j.appender.CA=org.apache.log4j.ConsoleAppender

log4j.appender.CA.layout.ConversionPattern= %d{hh:mm:ss,SSS} [%t] %-5p %c %x - %m%n
如果想要根据人来查询任务，配置文件需要修改
代码部分
/**
* 任务查询
*/
@Test
public void test005(){
ProcessEngine processEngine = cfg.buildProcessEngine();
TaskService taskService = processEngine.getTaskService();
List<Task> tasks = taskService.createTaskQuery()
.processDefinitionKey("holidayRequest")
.taskAssignee("李欣")
.list();
for (Task task : tasks) {
System.out.println("task.getProcessDefinitionId() = " + task.getProcessDefinitionId());
System.out.println("task.getName() = " + task.getName());
System.out.println("task.getAssignee() = " + task.getAssignee());
System.out.println("task.getDescription() = " + task.getDescription());
}
}
效果图
这里需要注意的是每次流程文件有修改都需要重新部署
完成任务效果图
新增类
package org.flowable;
import org.flowable.engine.delegate.DelegateExecution;
import org.flowable.engine.delegate.JavaDelegate;
/**
* @Description:
* @Author: 喵星人
* @Create: 2024/3/11 13:09
*/
public class SendRejectionMail implements JavaDelegate {
public void execute(DelegateExecution delegateExecution) {
System.out.println("审批被拒绝，发邮件来通知您....");
}
}
新增测试类
/**
* 任务完成
*/
@Test
public void test006(){
ProcessEngine engine = cfg.buildProcessEngine();
TaskService taskService = engine.getTaskService();
Task task = taskService.createTaskQuery()
.processDefinitionKey("holidayRequest")
.taskAssignee("李欣")
.singleResult();
Map<String,Object> variable=new HashMap<String, Object>(16);
variable.put("approved",false);
taskService.complete(task.getId(),variable);
}
