Convert JSON string to Pretty Print (Java, Gson)
This is the method to convert a JSON string to a pretty print version.
/**
* Convert a JSON string to pretty print version
* @param jsonString
* @return
*/
public static String toPrettyFormat(String jsonString)
{
JsonParser parser = new JsonParser();
JsonObject json = parser.parse(jsonString).getAsJsonObject();
Gson gson = new GsonBuilder().setPrettyPrinting().create();
String prettyJson = gson.toJson(json);
return prettyJson;
}
The way to use it:
@Test
public void testPrettyPrint()
{
String compactJson = "{\"playerID\":1234,\"name\":\"Test\",\"itemList\":[{\"itemID\":1,\"name\":\"Axe\",\"atk\":12,\"def\":0},{\"itemID\":2,\"name\":\"Sword\",\"atk\":5,\"def\":5},{\"itemID\":3,\"name\":\"Shield\",\"atk\":0,\"def\":10}]}";
String prettyJson = toPrettyFormat(compactJson);
System.out.println("Compact:\n" + compactJson);
System.out.println("Pretty:\n" + prettyJson);
}
