SpringMVC响应json不适合布尔属性

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.

Answer 1

Change your class to :

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

Answer 2

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.
