Java从转义的JSON字符串解析

Question

There are many threads related to this, but I can't solve my issue.

I get this string from parsing an iterable using GSON.

Iterable<ParametrosProveedores> proveedoresList;

proveedoresList = proveedoresRepository.findAll(); //From spring repository

String jsonString = gson.toJson(proveedoresList);

jsonString value is:

[{\"id\":1,\"proveedor\":\"CALIXTA\",\"unaVia\":true,\"dosVias\":true,\"plazasSi\":\"todas\",\"plazasNo\":\"\",\"turnoUnaVia\":false,\"turnoDosVias\":false},{\"id\":2,\"proveedor\":\"MOVILE\",\"unaVia\":true,\"dosVias\":true,\"plazasSi\":\"51,52\",\"plazasNo\":\"\",\"turnoUnaVia\":false,\"turnoDosVias\":false},{\"id\":3,\"proveedor\":\"TWILIO\",\"unaVia\":true,\"dosVias\":true,\"plazasSi\":\"todas\",\"plazasNo\":\"51\",\"turnoUnaVia\":false,\"turnoDosVias\":false},{\"id\":4,\"proveedor\":\"OTRO\",\"unaVia\":true,\"dosVias\":true,\"plazasSi\":\"todas\",\"plazasNo\":\"\",\"turnoUnaVia\":false,\"turnoDosVias\":false}]

Which is a json array. Is there really no way to parse from that string without removing escapes manually?

All I want to do is:

JSONArray jsonArray = parseFrom(jsonString);

Is it possible?

Answer 1

Since you are using a generic in the form of an Iterable<T> , you may need to use:

String jsonString = gson.toJson(proveedoresList, typeOfSrc);

Where typeOfSrc is the type of your proveedoresList . that way gson knows how to serialize the object properly.
