I can't find a good answer as to how to format a map in my json post when I want it to map directly to my Java pojo with the @RequestBody annotation. I'm assuming the json would look something like:

 "myInt":"10",
 "myMap":"1:"A""

My pojo would have a myInt field and a myMap field. The myMap field is of type Map<Integer,String>

What does the json for the map look like to get this to work?

According to your JSON structure myMap is a String. However, even if you remove the quotes from the value of myMap you will find that 1:"A" is not valid JSON, valid JSON syntax requires that all property keys are strings. A valid JSON structure would look like "1":"A". The deserializer should be able to coerce the key into an Integer, so Map<Integer, String> is fine.

First, make sure to have something like the following resource method:

@Path("/url")
public class Test 

 @POST
 @Consumes(MediaType.APPLICATION_JSON)
 public Response post(@RequestBody Foo foo) 
 ...
 

Then, when you send the request through POSTMAN, select the type as POST, then select the "raw" option and then just send a JSON in the "body" with the values you want to put in your Map. Remember to select "application/json" . Jackson will transform the JSON into a Map for you.

 "myInt": 10,
 "myMap": 
 1: "A"

  @Artanis you do not need quotes around the value, numeric values are valid JSON syntax, only the key must be a string. A value can be any of the primitive types (object, array, string, number, boolean).
