java – 如何使用http post将多个参数传递给restful webservice

发布时间：2020-12-15 04:11:58 所属栏目：Java 来源：网络整理

导读：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 "; .... ....

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;

    }

什么是我应该传递给这个方法的相应的json

我尝试了很多jsons,我总是得到这样的错误

注意：
我想从Android调用http post

解决方法

问题是在HTTP请求主体中发送的JSON被封送到第一个方法参数.您的其他参数未在请求中注明它们的来源,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到一个JSON对象中;就像是：

{

    "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,您需要定义一个表示MyJsonObject的类.

这篇SO帖子对配置RESTful服务有很好的解释：https://stackoverflow.com/a/8194612/2378728
