如何将JSON数组作为参数传递给URL

我需要在Web服务调用中将一些值从移动设备传递到服务器，因此我计划将JSON格式的所有值传递如下

{
    "nameservice": [
        {
            "id": 7413,
            "name": "ask"
        },
        {
            "id": 7414,
            "name": "josn"
        },
        {
            "id": 7415,
            "name": "john"
        },
        {
            "id": 7418,
            "name": "R&R"
        }
    ]
}

以下是我的服务电话

@RequestMapping("/saveName")
@ResponseBody
public String saveName(String acc)
{jsonObject = new JSONObject();
    try
    {
    );
    System.out.println(acc);
    jsonObject.accumulate("result", "saved ");
    }
    catch(Exception e)
    {
        e.printStackTrace();jsonObject.accumulate("result", "Error Occured ");
    }
    return jsonObject.toString();
}

我正在尝试通过这种方式致电上述服务

localhost:8080/service/saveName?acc={ "nameservice": [ { "id": 7413, "name": "ask" }, { "id": 7414, "name": "josn" }, { "id": 7415, "name": "john" }, { "id": 7418, "name": "R&R" } ] }

但是输出是这样的

{ "nameservice": [ { "id": 7413, "name": "ask" }, { "id": 7414, "name": "josn" }, { "id": 7415, "name": "john" }, { "id": 7418, "name": "R

谁能告诉我为什么我没有获得所有的价值观？
