json lib

1. Json-lib can easily turn Java objects into Json-formatted strings, using tutorials (http://json-lib.sourceforge.net/usage.html) But when there is a time type in the Java object. Json-lib converts the time field into: {"Date": "Day": 3, "hours": 0,

When you use Json-lib to convert a Java.util.Date object directly into a JSON string, you usually get a format that is not what you want:System.out.println (Jsonserializer.tojson (new Date () )); // {"Date": +, "Day": 3, "hours": minutes, "month": 5

Here is a brief introduction to how to use the Json-lib Toolkit to complete the transformation between a Java object (or collection) and a JSON object (or collection) ~1. Translating Java objects into JSON (creating JSON)Key class: Jsonobject

Thanks to JS's native support for JSON, JSON is widely used for data transmission in many projects. How can we convert data from a Java object to a JSON object? How can we convert the foreground JSON object to a Java object for processing? This is a

Json-lib converts an uppercase json string to javabean, json-libjson Dependent jar: Commons-beanutils-1.9.3.jar Commons-collections-3.1.jar Commons-lang-2.4.jar Commons-logging-1.2.jar Ezmorph-1.0.6.jar Json-lib-2.4-jdk15.jar   Test procedure: 1.

When using Jsonobject.fromobject (BEAN,CFG) in the Json-lib package, the following situations may occur:1, (prevent self-contained) the converted object contains its own object, or object A is suspended under object B, Object B is also suspended

Solution1. Set the JSON-LIB to let it filter out fields that cause loops.Java codeCopy codeThe Code is as follows:JsonConfig config = new JsonConfig ();Config. setIgnoreDefaultExcludes (false );Config. setCycleDetectionStrategy

One, json-lib the required jar package:　　Json-lib.jar,Commons-beanutils.jar,commons-collections.jar,commons-lang.jar,commons-logging.jar, Ezmorph-1.0.6.jar (can search for downloads directly online). Second, use: 1, JSON string     JSON

First, to prevent the package self-containedIn Json-lib, when the object to be converted contains its own object, an exception is thrown there is a cycle in the hierarchy, the workaround:Jsonconfig.setcycledetectionstrategy
