Question

I have a request(POST or GET), having one variable “data” (coming from Xcode)
now data have assigned JSON object

data={"method":"Auth","action":"login"}

now I have a bean having exactly these two fields(i.e. method,action)

now in Spring controller I have method “login”.

I want this method to be invoked based on value in “action” of the request JSON object.

Now, I’m not getting what exactly types of annotation i should use.

Please help..

Answer 1

You need to add Jackson to the classpath, and add <mvc:annotation-driven> to your Spring context, then Spring will automatically register a MappingJacksonHttpMessageConverter for JSON Objects.

Now Annotate your method like this:

@ResponseBody
@RequestMapping("/some/path")
public YourResponseObject someName(@RequestBody YourRequestObject data){
    // do something here
}

(Both YourRequestObject and YourResponseObject will be automatically converted to and from JSON, but this works only for POST requests AFAIK)
