Course Introduction:JSON is a universal lightweight data storage and exchange format that is independent of programming languages. It is written based on JavaScript object syntax and is very suitable for Web development. Ajax is an asynchronous data loading technology that allows users to obtain data without leaving the current page. The user experience is excellent. This course combines json and ajax technologies to demonstrate the application scenarios of these two technologies with examples (the knowledge of php and mysql involved can be temporarily neglect)

Course Introduction:JSON-lib is a Java library for serializing and deserializing JavaBeans, maps, arrays and collections in JSON format. We can add elements to a JSON object using the element() method of the JSONObject class. We need to download all dependent jars, such as json-lib.jar, ezmorph.jar, commons-lang.jar, commons-collections.jar commons-beanutils.jar, and commons-logging.jar, and can use them in our java program Import the net.sf.json package to execute

Course Introduction:JSONObject is an unordered collection of name/value pairs, while Map is an object that maps keys to values. The map cannot contain duplicate keys, and each key can be mapped to at most one value. We need to use the JSON-lib library to serialize and deserialize maps in JSON format. Initially, we can create a POJO class and pass the instance as a parameter to the put() method of the Map class, and finally add this map instance to the () method of JSONObject in accumulateAll. Syntax publicvoidaccumulateAll(Mapmap) In the following example, we can convert Map to JSON object. Example importja

Course Introduction:JSON-lib is a Java library for serializing and deserializing JavaBeans, Maps, Arrays and Collections in JSON format. We can convert a bean to XML without type hints using the setTypeHintsEnabled() method of the XMLSerializer class, which sets whether JSON types can be included as attributes. We can pass false as parameter to this method to disable type hints in XML. Syntax publicvoidsetTypeHintsEnabled(booleantypeHintsEnabled) example importnet.sf.jso

Course Introduction:JSON-libAPI is a Java library for serializing and deserializing javabeans, maps, arrays and collections in JSON format. We need to convert the JSON string to a bean by first converting the string to a JSON object and then converting it to a javabean. Syntax publicstaticObjecttoBean(JSONObjectjsonObject,ClassbeanClass) In the following program, we can convert JSON string to bean. Example importnet.sf.json.JSONObject;importnet.sf.json.J
