如何使用Java中的javax.json API对JSON进行漂亮的打印？
我们可以在下面的示例中实现漂亮的打印JSON。
示例
import java.io.*; import java.util.*; import javax.json.*; import javax.json.stream.*; public class JSONPrettyPrintTest { public static void main(String args[]) { String jsonString = "{"name":"Raja Ramesh","age":"35","salary":"40000"}"; StringWriter sw = new StringWriter(); try { JsonReader jsonReader = Json.createReader(new StringReader(jsonString)); JsonObject jsonObj = jsonReader.readObject(); Map map = new HashMap(); map.put(JsonGenerator.PRETTY_PRINTING, true); JsonWriterFactory writerFactory = Json.createWriterFactory(map); JsonWriter jsonWriter = writerFactory.createWriter(sw); jsonWriter.writeObject(jsonObj); jsonWriter.close(); } catch(Exception e) { e.printStackTrace(); } String prettyPrint = sw.toString(); System.out.println(prettyPrint); // pretty print JSON } }登录后复制
