I would like to know how to convert a linear String (on mysql) into gson JsonArray.

So to resume:

"{\"name\":\"john\",\"age\":22,\"class\":\"mca\"}"

-> {"name":"john","age":22,"class":"mca"} (As JsonArray using gson)

Thank you very much <3

What have you tried? I mean, I hope you tried searching the web, and found a gazillion examples for how to invoke Gson, so in what way did that not work out for you? — Andreas

Use StringEscapeUtils.unescapeJson method. See: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING while using Gson library and How to transfer escaped JSON lines to list of beans related questions. — Michał Ziober

This should work.

import com.google.gson.*;

JsonParser parser = new JsonParser();
JsonElement tradeElement = parser.parse(yourString);
JsonArray jsonArray = tradeElement.getAsJsonArray();
System.out.println(jsonArray);
