Problem with org.codehaus.jackson.map.ObjectMapper

This ties to my other question here, in which I had issues with deserializing object using RestTemplate. I thought of deserializing the object myself using org.codehaus.jackson.map.ObjectMapper which RestTemplate internally uses. I am still not able deserialize using org.codehaus.jackson.map.ObjectMapper. However interestingly, I am able to deserialize it successfully using com.fasterxml.jackson.databind.ObjectMapper. This explains why RestTemplate is failing to deserialize?

The JSON response looks like,

Code:

---

{
"response": {
"Time": "Wed 2013.01.23 at 03:35:25 PM UTC",
"Total_Input_Records": 5,
},-
"message": "Succeeded",
"code": "200"
}

---

Converted this Json payload into a POJO using jsonschema2pojo

Code:

---

public class MyClass {
    @JsonProperty("response")
    private Response response;
    @JsonProperty("message")
    private Object message;
    @JsonProperty("code")
    private Object code;
    private Map<String, Object> additionalProperties = new HashMap<String, Object>();
    //bunch of getters and setters here
}
public class Response {
    @JsonProperty("Time")
    private Date Time;
    @JsonProperty("Total_Input_Records")
    private Object Total_Input_Records;
    private Map<String, Object> additionalProperties = new HashMap<String, Object>();
//bunch of getters and setters here
}

---

Here is the deserialization code,

Code:

---

String jsonStr = "{\"response\": {"
                                + "\"Time\": \"Wed 2013.01.23 at 03:35:25 PM UTC\","
                                + "\"Total_Input_Records\": \"5\"},"
                                + "\"message\": \"Succeeded\"," + "\"code\": \"200\"" + "}";

---

ObjectMapper mapper = new ObjectMapper();
MyClass wrapper mapper.readValue(jsonStr, MyClass.class);

Below is the exception I get with org.codehaus.jackson.map.ObjectMapper[/CODE]. Again, this exact code WORKS with com.fasterxml.jackson.databind.ObjectMapper

Code:

---

org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "Time" (Class com.temp.pointtests.Response), not marked as ignorable
 at [Source: java.io.StringReader@2c9b42e6; line: 1, column: 24] (through reference chain: MyClass["response"]->Response["Time"])

I think I know what the issue is. I saw Spring added MappingJackson2HttpMessageConverter which uses Jackson 2. I can now add MappingJackson2HttpMessageConverter to my RestTemplate and everything works fine :-). Here is the code for people who have the same issue,

Code:

---

String url = "http://mysite.com/someparams";
RestTemplate template = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);       
HttpEntity request = new HttpEntity(headers);
List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();
MappingJackson2HttpMessageConverter map = new MappingJackson2HttpMessageConverter();
messageConverters.add(map);
messageConverters.add(new FormHttpMessageConverter());
template.setMessageConverters(messageConverters);
MyClass msg = template.postForObject(url, request, MyClass.class);
