Deserialize JSON to Object using Jersey

问题

I am using Jersey which was creating an object out of the JSON or xml from the client.

Now, I am using JSONp to create a object. Since jsonp cannot do a post, I am left with sending data using get.

1. Can I use GET request and still deserialize? I know I can use @QueryParam for each and then somehow deserialize. But like POST and Put, can I just give it a input parameter and expect Jersey to deserialize automaticaly.

2. How can I deserialize a json into java object using Jersey?

Thanks.

回答1:

After some research, it is not difficult to deserialize directly from json. This is how I did it.

Send JSON as a queryparam from the client side with keys matching the object field-names.

ObjectMapper mapper = new ObjectMapper();
Contact contact = mapper.readValue(json, Contact.class);

You can use ObjectMapper to deserialize - piece of cake ;)
