【问题描述】：

我有两个数组参数和对象数组，我想传递它们我可以使用这样的方法吗

 @POST
 @Path("Test3")
 @Produces("text/plain")
 @Consumes({"application/json"})
  public String Test3(String[] id1,String[] id2 ,Object [] oo) {
        String result = "Hello ";

       ....
       ....
        return result;

    }

我应该传递给这个方法的对应的json是什么

我尝试了很多 json，但总是遇到这样的错误

注意：我想从 Android 调用 http post

【解决方案1】：

问题是在 HTTP 请求正文中发送的 JSON 被编组到第一个方法参数。您的其他参数未在请求中注释它们来自何处，这就是您收到错误的原因：

ItemFacadeREST contains multiple parameters with no annotation.

您最好的选择是将参数组合成一个 JSON 对象；类似：

{

    "id1":[
        "string1",
        "string2"
    ],
    "id2":[
        "string3",
        "string4"
    ],
    "oo":[
        {
            "object1":""
        },
        {
            "object2":""
        }
    ]
}

然后将您的方法更改为：

 @POST
 @Path("Test3")
 @Produces("text/plain")
 @Consumes({"application/json"})
  public String Test3(MyJsonObject json) {
        //Parse the JSON object 

    }

当然，您需要定义一个代表MyJsonObject 的类。
