如何将 Map 类型的参数从 Java 传递给 orientdb groovy 函数

Question

我正在尝试将 Map 作为我的 orientdb groovy 函数的输入。但是 Groovy 函数正在将我的 Map 输入参数视为字符串。

请建议如何将输入参数的 Map 类型传递给 orientdb groovy 函数。

代码

public void MapInputTest() {
     Map < String, Object > inputMap = new HashMap < String, Object > ();
     inputMap.put("serviceId", "ETHA12721205");
     inputMap.put("serviceId1", "ETHA127212051");
     inputMap.put("serviceId2", "ETHA127212052");

     g.execute(Script.function("MapInputFunction", inputMap));
     System.out.println("returnedString is : ");
}

groovy 函数:

def MapInputFunction(Map mapInput) {
    println("class type of input parameter" + mapInput.getClass())
    println("class type " + mapInput)
    def tempMap = [: ]
    tempMap = mapInput
    return tempMap.get('serviceId')
}

错误

在脚本中，假设参数的名称是 inputMap

然后发送以下内容

 Map < String, Object > parameters= new HashMap < String, Object > ();
     parameters.put("serviceId", "ETHA12721205");
     parameters.put("serviceId1", "ETHA127212051");

 Map < String, Object > inputMap = new HashMap < String, Object > ();
inputMap.put("inputMap",inputMap)

     g.execute(Script.function("MapInputFunction", inputMap));
     System.out.println("returnedString is : ");

脚本将能够读取作为地图数据结构的 inputMap
