Read Json file in JAVA with io.vertx.core.json library
The problem is that you're using the parser from another library and expecting to get an instance of io.vertx.core.json.JsonObject. Instead, read your file containing your JSON text into a Java string. Note that you can do this using the IOUtils.toString(Reader) method. Then, use the JsonObject's constructor. For example, you could just use something similar to the following code:
String jsonStr = IOUtils.toString(new FileReader(myFileName));JsonObject jsonObj = new JsonObject(jsonStr);Hope that helps!
