Changing the Prior SampleServiceImpl.java Code

top

o We are going to reuse the implementation we created so far
o But, the getMessage() is going to return the JSON data
o We will add this method to our SampleServiceImpl.java:

private String getJSONMessage() {
 StringBuilder msg = new StringBuilder();
	msg.append("[n");
	msg.append("  {n");
	msg.append("     "message": "message goes here"n");
	msg.append("  }n");
	msg.append("]n");

	return msg.toString();
}

o The getMessage() method is changed from:

@Override
public String getMessage() throws IllegalArgumentException {
	return "message goes here";
}

o To this, where we call the getJSONMessage() method:

@Override
public String getMessage() throws IllegalArgumentException {
	return getJSONMessage();
}
