    private String shortName;

    HelloEnum (String shortName) {
        this.shortName = shortName;
    }

    @Override

        return shortName;
    }

    @JsonCreator
    public static HelloEnum create (String value) {
        if(value == null) {
            throw new IllegalArgumentException();
        }
        for(HelloEnum v : values()) {
            if(value.equals(v.getShortName())) {
                return v;
            }
        }
        throw new IllegalArgumentException();
    }

    public String getShortName() {
        return shortName;
    }
}

public class ExampleHelloEnum {
    public static void main(String args[]) throws IOException {
        ObjectMapper objectMapper = new ObjectMapper();

        Map<HelloEnum,String> testMap = new HashMap<HelloEnum,String>();
        testMap.put(HelloEnum.HELLO, "hello string");
        testMap.put(HelloEnum.WORLD, "world string");

System.out.println(objectMapper.writeValueAsString(testMap));

         Map<HelloEnum,String> newTestMap = objectMapper.readValue(objectMapper.writeValueAsString(testMap), new TypeReference<Map<HelloEnum,String>>() {});

         System.out.println(newTestMap.get(HelloEnum.HELLO));
         System.out.println(newTestMap.get(HelloEnum.WORLD));
     }
}

And here is the output:

{"h":"hello string","w":"world string"}
hello string
world string
