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 May 28 '19 at 19:03

  • Use `StringEscapeUtils.unescapeJson` method. See: [java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING while using Gson library](https://stackoverflow.com/questions/55178300/java-lang-illegalstateexception-expected-begin-array-but-was-string-while-using/55178991#55178991) and [How to transfer escaped JSON lines to list of beans](https://stackoverflow.com/questions/55089762/how-to-transfer-escaped-json-lines-to-list-of-beans/55092560#55092560) related questions. – Michał Ziober May 28 '19 at 20:34

This should work. 

import com.google.gson.*;

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