I'm using the Apache http classes to call a web service that returns a JSON object in the response body. I have a Jackson annotated java class mapped to the JSON object. I want to do something this, but google hasn't turned up the correct boilerplate.
String url = hostName + uri; HttpGet httpGet = new HttpGet(url); HttpResponse response = httpclient.execute(httpGet); MyObject myObject = (MyObject)response.getEntity().getContent();
How to deserialize Date from JSON using Jackson. In order to correct deserialize a Date field, you need to do two things: 1) Create a custom deserializer by extending StdDeserializer<T> class and override its deserialize(JsonParser jsonparser, DeserializationContext context) method.
Converting Java object to JSON In it, create an object of the POJO class, set required values to it using the setter methods. Instantiate the ObjectMapper class. Invoke the writeValueAsString() method by passing the above created POJO object. Retrieve and print the obtained JSON.
Jackson is a powerful and efficient Java library that handles the serialization and deserialization of Java objects and their JSON representations. It's one of the most widely used libraries for this task, and runs under the hood of many other frameworks.
You have to use the ObjectMapper
:
MyObject myObject = objectMapper.readValue(response.getEntity().getContent(), MyObject.class);
(An object mapper instance can be reused, so no need to create a new one for each deserialization)
