Camunda BPMN Converter

Convert json to bpmn for Camunda Platform.

1. 节点类型（nodeType)

• serviceTask
  • service 任务节点
• userTask
  • userTask 任务节点
• parallelGateway
  • 并行节点
• exclusiveGateway
  • 排他节点

2. 数据结构

• serviceTask

{
    "nodeName":"审核人1",
    "nodeType":"serviceTask",
    "nextNode": null
}

• userTask

{
    "nodeName":"审核人1",
    "nodeType":"userTask",
    "assignee": "aaa",
    "candidateUsers": "bbb,ccc",
    "candidateGroups": "bbb,ddd",
    "nextNode": null
}

对于 parallelGateway/exclusiveGateway 类型，目前建议设置 nextNode 的 nodeType 类型一一对应

• exclusive

{
    "nodeName":"排他",
    "nodeType":"exclusiveGateway",
    "nextNode":{
        "nodeName":"",
        "nodeType":"exclusiveGateway",
        "nextNode":null
    },
    "branchNodes":[
        {
            "nodeName":"条件1",
            "conditionExpression":"=id>1",
            "nextNode":{
                "nodeName":"审核人2.1",
                "nodeType":"serviceTask",
                "nextNode": null
            }
        },
        {
            "nodeName":"条件2",
            "conditionExpression":"=id<1",
            "nextNode":{
                "nodeName":"审核人2.2",
                "nodeType":"serviceTask",
                "nextNode":null
            }
        },
        {...}
    ]
}

• parallel

{
    "nodeName":"并行任务",
    "nodeType":"parallelGateway",
    "nextNode":{
        "nodeName":"",
        "nodeType":"parallelGateway",
        "nextNode":null
    },
    "branchNodes":[
        {
            "nextNode":{
                "nodeName":"审核人2.1",
                "nodeType":"serviceTask",
                "nextNode": null
            }
        },
        {
            "nextNode":{
                "nodeName":"审核人2.2",
                "nodeType":"serviceTask",
                "nextNode":null
            }
        },
        {
            "nextNode":{
                "nodeName":"审核人2.3",
                "nodeType":"serviceTask",
                "nextNode":null
            }
        },
        {...}
    ]
}

                        "nextNode":null
                    }
                }
            ]
