SpringMVC response json not right for Boolean properties

Question

I use SpringMVC 4.2.5, and make a rest Controller, but the response is not what I want. Here it's the detail. I have an Entity named propertyEntity,

public class PropertyEntity implements Serializable, Cloneable {
    private static final long serialVersionUID = -7032855749875735832L;
    private int id;
    private String propertyName;
    private boolean isEnable;
    private boolean isDimension;
    private boolean isMetric;
}

and the Controller is:

@Controller
@RequestMapping("/api/v1/properties")
public class PropertyController {
    @RequestMapping(method = RequestMethod.GET,
                produces = "application/json;charset=utf-8")
    @ResponseStatus(HttpStatus.OK)
    public @ResponseBody
    List<PropertyEntity> getAll() {
         return propertyService.getAll();
    }
}

When I request the api, the result is:

[
    {
        "id": 1,
        "propertyName": "money1",
        "isEnable": true,
        "dimension": false,
        "metric": true
  },
  {
        "id": 2,
        "propertyName": "money2",
        "isEnable": true,
        "dimension": false,
        "metric": true
  } 
]

what I want is:

[
    {
        "id": 1,
        "propertyName": "money1",
        "isEnable": true,
        "isDimension": false,
        "isMetric": true
  },
  {
        "id": 2,
        "propertyName": "money2",
        "isEnable": true,
        "isDimension": false,
        "isMetric": true
  } 
]

The unexpected thing is: isDimention is changed to dimension, isMetric is changed to metric, but isEnable is right.

Weird. That seems like a bug if only one of the properties behaves that way. — dbreaux, Aug 24 '16 at 04:00

Change your class to :

public class PropertyEntity implements Serializable, Cloneable {
    ...
    ...
    @JsonProperty("isEnable")
    private boolean isEnable;
    ...
    ...
}

I tried adding @JsonProperty("isMetric"), yes, it turns out to `isMetric` result, but `metric` is still there, so I think the reason is what @ishanbakshi says. Thanks all the same, and for the useful link. – Skyler Tao Aug 24 '16 at 07:28

I assume you are using jackson for converting the "PropertyEntity" object to a json.

A possible problem here could be the getters and setters in PropertyEntity class.

See the getter/setter of isEnable and follow a similar naming convention for isMetric & isDimension

ensure that the getters of boolean start with isIsMetric()... instead of getIsMetric().

If this does not help, please share your getters and setters over here.

Yes, it's the getters and setters method name, change to getIsMetric() and setIsMetric(boolean isMetric) solves the problem. Thanks! – Skyler Tao Aug 24 '16 at 07:25
