如何通过地图类型的参数从Java

orientdb常规的性能，我试图通过Map作为输入到我的orientdb常规功能。但Groovy函数正在考虑我的Map输入参数为String。如何通过地图类型的参数从Java

请建议如何通过输入参数的地图类型orientdb常规功能。

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 : "); 
}

常规功能：

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

什么是'g'和'Script'。如果你包含更多的代码，它会更容易帮助。 – sbglasius

考虑g表示来自DB的图表实例 –

在脚本，让我们说该参数的名称是的InputMap

然后发送下面

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 : ");

该脚本将能够读取的InputMap作为地图数据结构
