activiti

Question

我正在使用一个简单的Hello world示例测试activiti中的服务任务。我创建了这个过程，它将在控制台中显示hello world，但是一旦我运行main，我什么都没有。

    // Fetch all tasks for the management group
    TaskService taskService = processEngine.getTaskService();
    java.util.List<org.activiti.engine.task.Task> tasks = taskService.createTaskQuery().taskCandidateGroup("management").list();

公共类Test3实现了JavaDelegate {

public void execute(DelegateExecution arg0) throws Exception {
    System.out.println("tessssssssssssst");
}

}

Answer 1

您可以使用以下内容，

public class Test3Delegate extends BaseJavaDelegate{
@Override
public void execute(DelegateExecution delegate) throws Exception
{
    System.out.println("tessssssssssssst");
}
}

在bpmn文件中，您可以引用delegateExpression，

<serviceTask id="servicetask1" name="Service Task" activiti:delegateExpression="${Test3Delegate}"></serviceTask>

在模块上下文文件中，注册如下，

<bean id="Test3Delegate" parent="BaseJavaDelegate"  class="package.name.Test3Delegate"></bean>

希望这会对你有所帮助。

问题在于流程引擎配置
