java - Spring: request-payload with only one element -

i want implement web-service consumes 1 named parameter in request-payload. in curl view should smth like: curl -x patch myurl.net/my_service -d "{mysingleparameter: 49}"

i'm trying spring, wondered map such payload method must declare new class. like:

... public static class payloadwithsingleparammsp{   public long mysingleparameter; }  @requestmapping(value = "my_service", method = requestmethod.patch) public string myservice(@requestbody payloadwithsingleparammsp payload){   long valuewhichireallyneed = payload.mysingleparameter;   //do job   ... } ... 

but there way take value need (mysingleparameter) directly?

you have couple options:

    @requestmapping(value = "my_service", method = requestmethod.patch)     public string myservice(@requestbody objectnode payload){         long valuewhichireallyneed = payload.get("mysingleparameter").aslong();         //do job        ...     } 

or

@requestmapping(value = "my_service", method = requestmethod.patch) public string myservice(@requestbody map<string, string> payload){     long valuewhichireallyneed = long.parselong(payload.get("mysingleparameter"));     //do job     ... } 

or even

@requestmapping(value = "my_service", method = requestmethod.patch) public string myservice(@requestbody  long mysingleparameter){     long valuewhichireallyneed = mysingleparameter;     //do job     //  ... } 

but in last case curl following:

curl -x patch myurl.net/my_service -d "49"
