Question

我正在使用spring boot开发rest api服务。我的项目有一个名为CarWash的实体类，带有字段

import com.vividsolutions.jts.geom.Point;
@Column(columnDefinition = "Point", name = "lon_lat")
    private Point lonLat;
 @Column(name = "address")
private String address;

这是我的控制器方法

@RequestMapping(value = "owner/carWashs", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")


 @ResponseBody
    public ResponseEntity<String> createCarWash(@RequestParam(value = "sid", required = true, defaultValue = "") String sid,
                                               @RequestBody CarWash carWash) throws TimeoutException, SocketTimeoutException, SocketException {
        final Integer id = checkSession(sid);
        System.out.println(carWash.getLonLat());
        System.out.println(carWash.getAddress());
        return ResponseEntity.ok(createCarWashLogic(carWash));
    }

当我使用这个json {"address":"qwerty"}调用此方法时，它可以正常工作。问题是如何将lonLat属性添加到请求体中以便jackson能够将其解析为POINT对象？

Answer 1

假设您有

class Point{ String attribute1; String attribute2; }

发送Carwash json，如

{ "address":"qwerty", "lonLat" : { "attribute1":"value", "attribute2":"value" } }

和杰克逊将相应地设置属性值。

Answer 2

点 class的字段 CoordinateSequence坐标，该字段的字段为 int X，int Y，int Z，int M < / strong>即可。所以你的json字符串应该是这样的：

{ "address": "some address", "lonLat": { "coordinates": { "X": 123, "Y": 123, "Z": 123, "M": 123, } } }

将点对象传递给@RequestBody
