In Java projects, it is very common to convert an object into a string in Json format. many toolkits can meet this requirement, such as Gson, JSON-lib, and Jackson. This article mainly introduces the use of Jackson. in addition to implementing the conversion between Java objects and

The common JSON libraries under Java are Gson, Json-lib, and Jackson, and Jackson is relatively efficient, using Jackson for JSON and Java object transformations in the project, with some of Jackson's

The Apache Wink is rapidly growing into one of the standard implementations of the JAX-RS 1.0 specification. The providers for the JSON grouping and reconciliation group included with the Apache Wink version, such as json.org and jettison, have some problems with array representation, and the return type is relatively limited. It is difficult to write Jax-rs services and their customers asynchronous JavaScript and XML (Ajax) applications. In this arti
