When converting the java.util.Date type to JSON, use Jsonvalueprocessor to convert the date to the desired type

When converting the java.util.Date type to JSON, use Jsonvalueprocessor to convert the date to the desired type

Problem Description:

This is how the time type in Java is converted into JSON data:
"Createtime": {"date": +, "Day": 3, "hours": +, "minutes": +, "month": 3, "Nanos": 0, "seconds"
: "Time": 1209539678000, "Timezoneoffset": -480, "Year": 108}
The desired result:

Convert Date to YYYY-MM-DD form

Solution:

To register the Time field processor, use Jsonconfig to:
Jsonconfig jsonconfig = new Jsonconfig ();
Jsonconfig.registerjsonvalueprocessor (Java.util.Date.class, New Datejsonvalueprocessor ("Yyyy-mm-dd HH:mm:ss"));
Jsonobject jsonobj = jsonobject.fromobject (map, jsonconfig);

Class Datejsonvalueprocessor implements Jsonvalueprocessor {
Private String format = "YYYY-MM-DD";

Public Datejsonvalueprocessor () {
}

Public datejsonvalueprocessor (String format) {
This.format = format;
}

public object Processarrayvalue (object value, Jsonconfig jsonconfig) {
string[] obj = {};
if (value instanceof date[]) {
SimpleDateFormat SF = new SimpleDateFormat (format);
date[] dates = (date[]) value;
obj = new String[dates.length];
for (int i = 0; i < dates.length; i++) {
Obj[i] = Sf.format (Dates[i]);
}
}
return obj;
}

Public Object Processobjectvalue (String key, object value, Jsonconfig jsonconfig) {
if (value instanceof Date) {
String str = new SimpleDateFormat (format). Format ((Date) value);
return str;
}
return value.tostring ();
}

Public String GetFormat () {
return format;
}

public void SetFormat (String format) {
This.format = format;
}

}
