如何在调用Camunda原生RESTAPI接口时给多实例节点传入集合变量

Camunda提供了多种类型的变量类型支持，详情请查看官方文档

多实例节点属性有集合变量，常用于并审或调用子流程节点，示例如下：

多实例节点-人工任务-并审-集合变量名：assigneeList

<?xml version="1.0" encoding="UTF-8"?> Flow_1lqot0o Flow_0qdzfen Flow_1lqot0o Flow_0yuchf0 Flow_0yuchf0 Flow_0qdzfen ${nrOfCompletedInstances==1}

多实例节点-调用子流程-并行-集合变量名：itemList

<?xml version="1.0" encoding="UTF-8"?> Flow_1kmyk0u Flow_1kmyk0u Flow_0cmzdl8 Flow_0cmzdl8

修改pom.xml文件，添加以下依赖：

org.camunda.bpm camunda-engine-plugin-spin org.camunda.spin camunda-spin-dataformat-all

重启服务，并部署模型，部署成功后，打开Postman或ApiPost等客户端，参考原生REST API Start Process Instance | docs.camunda.org 发起流程

请求报文：

{ "variables":{ "assigneeList":{ "value":"["bx2","bx3"]", "type":"Object", "valueInfo":{ "objectTypeName":"java.util.ArrayList", "serializationDataFormat":"application/json" } }, "starter":{ "value":"bx1", "type":"String" } }, "businessKey":"myBusinessKey2", "withVariablesInReturn":true}

响应报文：

{ "links":[ { "method":"GET", "href":"http://127.0.0.1:8080/engine-rest/process-instance/d593cf3e-8cac-11ec-b78f-8c1645647a47", "rel":"self" } ], "id":"d593cf3e-8cac-11ec-b78f-8c1645647a47", "definitionId":"Process_1fh6max:1:89fe12a3-8c7e-11ec-a02b-8c1645647a47", "businessKey":"myBusinessKey2", "caseInstanceId":null, "ended":false, "suspended":false, "tenantId":null, "variables":{ "assigneeList":{ "type":"Object", "value":"["bx2","bx3"]", "valueInfo":{ "objectTypeName":"java.util.ArrayList", "serializationDataFormat":"application/json" } }, "starter":{ "type":"String", "value":"bx1", "valueInfo":{ } } }}

 登陆WebApp并切换到Tasklist执行提交节点任务到提交，检查是否可以正常提交，以及并审任务节点是否可以产生2个任务实例
