Use Jackson to convert object,map,list, arrays, enumerations, date classes, etc. into JSON

Jackson configured the Jsonbinder to determine which JSON object to convert,

In spring configuration

Org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

 /**     *  Create a binder.     */  that outputs all properties to a JSON string    public static jsonbinder buildnormalbinder ()  {         return new jsonbinder (inclusion.always);    }     /**     *  Create a binder.     that only outputs non-empty properties to the JSON string  */    public static jsonbinder buildnonnullbinder ()  {         return new jsonbinder (inclusion.non_null);     }    /**     *  creates a binder that only outputs the changed properties of the initial value to the JSON string.      */    public static JsonBinder  Buildnondefaultbinder ()  {        return new jsonbinder ( Inclusion.non_default);     } 

Use Jackson to convert object,map,list, arrays, enumerations, date classes, and so on to JSON
