Deserializate only certain JSON tags with Jackson

deserialization, jackson, java, json

Solution

It looks like you want to disable FAIL_ON_UNKNOWN_PROPERTIES.

Problem

Is there a way that I dont have to extract the tags I need "manually" from the JSON if I don't want to deserialize all of them so that I can use this constructor? ``` public class Tweet { public String username; public String message; public String image_url; @JsonCreator public Tweet( @JsonProperty("from_user") String username, @JsonProperty("text") String message, @JsonProperty("profile_image_url") String url) { this.username = username; this.message = message; this.image_url = url; } } ``` And here it is the JSON: ``` { "created_at":"Wed, 15 Aug 2012 18:17:55 +0000", "from_user":"felix_panda", "from_user_id":132396774, "from_user_id_str":"132396774", "from_user_name":"felix suganda", "geo":null, "id":235802515571101696, "id_str":"235802515571101696", "iso_language_code":"en", "metadata":{ "result_type":"recent" }, "profile_image_url":"http:\/\/a0.twimg.com\/profile_images\/2393214158\/profile_normal.jpg", "profile_image_url_https":"https:\/\/si0.twimg.com\/profile_images\/2393214158\/profile_normal.jpg", "source":"<a href="http:\/\/www.tweetcaster.com" rel="nofollow">TweetCaster for Android<\/a>", "text":"@Android how do u fix you lost your data connection because you left home network with data roaming (cont) http:\/\/t.co\/4coRjaXT", "to_user":"Android", "to_user_id":382267114, "to_user_id_str":"382267114", "to_user_name":"Android" ``` This is the error I get when deserializing it: ``` com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "created_at" ```
