jbpm--(六)jpdl流程定义语言

1. state节点

<?xml version="1.0" encoding="UTF-8"?>

<process key="state" name="state" xmlns="http://jbpm.org/4.4/jpdl">

        // TODO Auto-generated method stub

    }

     * 注意
     * 状态节点前进流转，和任务不同
     */
    @Override

        //taskService.completeTask("");
        executionService.signalExecutionById("state.140001");
    }

2.task节点

参考前面的文章

3.任务分配的几种方式

Assignee

AssignmentHandler

Swimlanes

Candidate-groups
