What is the JSP equivalent to json_encode ( in PHP )?

Question

I am trying to encode a JSP servlet into JSON. What\'s the equivalent in JSP to json_encode() in PHP ?

Answer 1

json_encode in php is similar to following package in java

dependency:

import com.fasterxml.jackson.databind.ObjectMapper;

code :

Map dataArray = {some data in map}
ObjectMapper objMapper = new ObjectMapper();
String jsonString = objMapper.writeValueAsString(dataArray);

jsonString is if the final result like son_encode in php, which you can achieve with objectMapper class
