As the title describes I'm trying to assign a json string to my class, but the json string will presumably contain several variables which I have not created in the class they are being assigned to.
To show you first what works, I have
ObjectMapper mapper = new ObjectMapper();
try {
Tweet tweet1 = mapper
.readValue(
"{\"created_at\":\"Sat Feb 08 11:26:02 +0000 2014\"}",
Tweet.class);
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
That works, as the class, Tweet, has the variable "created_at" with getter and setter methods all in place.
Like mentioned though, I need to expect the string in the readValue method to contain things which are not to be found in my Tweet class.
To get around this, I import and use:
mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
Which theoretically helps me avoid all the unknowns in there, and just assigns the values that are to be found in the Tweet class.
So, I add a value which is not to be found in Tweet, like so:
ObjectMapper mapper = new ObjectMapper();
mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
try {
Tweet tweet1 = mapper
.readValue(
"{\"created_at\":\"Sat Feb 08 11:26:02 +0000 2014\",\"id\":432113085571407872\"}",
Tweet.class);
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Now, the value "id" does not exist in my Tweet class, and should therefor be ignored (no?).
But, now the console throws me an error:
com.fasterxml.jackson.core.JsonParseException: Unexpected character ('"' (code 34)): was expecting comma to separate OBJECT entries at [Source: java.io.StringReader@7817ea54; line: 1, column: 72]
Now this makes me a sad panda, because I cannot for the life of me understand what it is I'm doing wrong.
Anyone with better eyes and/or a sharper mind than mine, see my mistake?
Or am I going about this all wrong?
