I have the following string in a resource file and I am trying to deserialise to Map using ObjectMapper
{ 13714974: { get-url: "https://example.com/get", post-url: "https://example.com/post" }, 13743772: { get-url: "https://example.com/get", post-url: "https://example.com/post" }
ObjectMapper mapper = new ObjectMapper();
mapper.configure(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
Map<String, Map<String, String>> cmMappings = mapper.readValue(content, Map.class);
When I use codehaus jackson ObjectMapper and try to deserialise it, I get the exception,
Exception in thread "main" org.codehaus.jackson.JsonParseException: Unexpected character ('1' (code 49)): was expecting either valid name character (for unquoted name) or double-quote (for quoted) to start field name

and when running the code to deserialise a resource file containing string of this format I get Exception while deserialising because of hyphen in field names
.
I tried fasterxml ObjectMapper also but it does not work
So how do I debug the string to the map ?
This is how we deserialise the above String
try {
ObjectMapper mapper = new ObjectMapper();
ClassPathResource resource = new ClassPathResource("resourceFile");
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
mapper.configure(com.fasterxml.jackson.core.JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
TypeReference<HashMap<String, Map<String, String>>> typeRef = new TypeReference<HashMap<String, Map<String, String>>>() {};
cmMappings = mapper.readValue(resource.getInputStream(), typeRef);
} catch (Exception ex) {
// log error
}
