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相应json是什么

我尝试了很多 jsons,但总是遇到这样的错误

注意:我想从 Android 调用 http post

最佳答案

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

ItemFacadeREST contains multiple parameters with no annotation.

最好的选择是将参数组合成一个 JSON 对象;像这样的东西:

{

"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。
