ObjectMapper provides functionality for reading and writing JSON, either to and from basic POJOs (Plain Old Java Objects), or to and from a general-purpose JSON Tree Model ( JsonNode ), as well as related functionality for performing conversions. It is also highly customizable to work both with different styles of JSON content, and to support In this example, we use JSON-B's toJson method to convert a Java object into a JSON string. Like ObjectMapper and Gson, JSON-B also provides a method for converting a JSON string back into a Java object. Choosing the Right Library. Choosing the right library for Java-JSON conversion depends on your specific needs and the context of your project. The jackson API has changed: It's still possible (with Jackson 2.7.6) to use new ObjectMapper().configure(SerializationFeature.INDENT_OUTPUT, true).writer().writeValueAsString(new HashMap<String, Object>());. You just have to make sure to use the writer you get from the configured ObjectMapper. Jacksonの使い方を現役エンジニアが解説【初心者向け】. 初心者向けにJacksonの使い方について解説しています。.
