When returning VO as json, how to return excluding null value?
@RequestMapping("/rbtInfo.do")
public RobotVO rbtInfo(@RequestParam String rbtId){
String rbtPower = "ON";
robot.setRbtPower(rbtPower);
return robot;
}
Above is my controller.
And the return value is as follows.
{
"rbtId": null,
"rbtPower": "ON",
"rtspAddr": null,
"ifrRtspAddr": null,
"stationPosition": null,
}
In this case, I want to return only rbtPower
for which the value exists, but not the rest.
How can I return excluding null data from VO?

You can use below annotation at class level or method level for RobotVO.
@JsonInclude(Include.NON_NULL)
