如何在调用Camunda原生REST API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

  
    
      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

  
    
      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
