This error occurs when you try to cast an Integer object to a JSONObject object using the FastJSON library. This is not possible because the two types are not compatible.
To fix this error, you need to ensure that you are using the correct data types in your code. If you are expecting a JSONObject, make sure that the value you are trying to cast is actually a JSONObject and not an Integer.
You can also use the instanceof operator to check the type of an object before casting it. For example:
if (myObject instanceof JSONObject) {
JSONObject jsonObj = (JSONObject) myObject;
// do something with the JSONObject
} else {
// handle the error
}
By using the instanceof operator, you can avoid casting errors and handle unexpected data types in a more graceful manner.
