使用Jersey将反序列化JSON到对象反序列化 [英] Deserialize JSON to Object using Jersey
问题描述
我使用的是Jersey,它使用客户端的JSON或xml创建对象.
I am using Jersey which was creating an object out of the JSON or xml from the client.
现在,我正在使用JSONp创建对象.由于jsonp无法发表信息,因此我只能使用get发送数据.
Now, I am using JSONp to create a object. Since jsonp cannot do a post, I am left with sending data using get.

我可以使用GET请求并且仍然反序列化吗?我知道我可以为每个使用@QueryParam,然后以某种方式反序列化.但是像POST和Put一样,我可以给它一个输入参数,并希望Jersey自动进行反序列化.
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.
如何使用Jersey将一个json序列化为Java对象?
How can I deserialize a json into java object using Jersey?
谢谢.
推荐答案
经过一些研究,直接从json反序列化并不困难.这就是我的方法.
After some research, it is not difficult to deserialize directly from json. This is how I did it.
使用与对象字段名称匹配的键从客户端发送JSON作为queryparam.
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);
您可以使用ObjectMapper对小菜一碟进行反序列化;)
You can use ObjectMapper to deserialize - piece of cake ;)
