Java – how to pass multiple parameters to a restful web service using HTTP post
•
Java
I have two array parameters and an object array, and I want to pass them
@POST
@Path("Test3")
@Produces("text/plain")
@Consumes({"application/json"})
public String Test3(String[] id1,String[] id2,Object [] oo) {
String result = "Hello ";
....
....
return result;
}
What is the corresponding JSON that I should pass to this method
I tried a lot of jsons and I always got such mistakes

Note: I want to call HTTP post from Android
Solution
The problem is that JSON sent in the HTTP request body is marshaled to the first method parameter Your other parameters did not indicate their source in the request, which is why you received the error:
ItemFacadeREST contains multiple parameters with no annotation.
Your best choice is to combine parameters into a JSON object; It's like:
{
"id1":[
"string1","string2"
],"id2":[
"string3","string4"
],"oo":[
{
"object1":""
},{
"object2":""
}
]
}
Then change your method to:
@POST
@Path("Test3")
@Produces("text/plain")
@Consumes({"application/json"})
public String Test3(MyJsonObject json) {
//Parse the JSON object
}
Of course, you need to define a class that represents myjsonobject
