java - Spring @RequestBody 与 GeoJsonPoint

Question

尝试将 GeoJsonPoint JSON 的 POST 请求映射到 GeoJsonPoint 模型时，但没有成功。

REST Controller :

@RestController
@RequestMapping("/location")
public class LocationController {

    @PostMapping(consumes = "application/json")
    public MyLocation recieveAddress(@RequestBody MyLocation location) {
        return location;
    }

    @GetMapping(consumes = "application/json")
    public MyLocation returnAddress() {
        MyLocation loc = new MyLocation();
        loc.setLocation(new GeoJsonPoint(0.123321, 0.3453455));
        return loc;
    }
}

类(class):

public class MyLocation {

    private GeoJsonPoint location;

    public MyLocation() {   
    }

    public void setLocation(GeoJsonPoint location) {
        this.location = location;
    }

    public GeoJsonPoint getLocation() {
        return this.location;
    }

}

GET请求返回:

{
    "location": {
        "x": 0.123321,
        "y": 0.3453455,
        "type": "Point",
        "coordinates": [
            0.123321,
            0.3453455
        ]
    }
}

当发布上述内容并进行调试时，我得到:

DEBUG 11860 --- [nio-8090-exec-2] o.s.b.a.e.mvc.EndpointHandlerMapping     : Looking up handler method for path /location 
DEBUG 11860 --- [nio-8090-exec-2] o.s.b.a.e.mvc.EndpointHandlerMapping     : Did not find handler method for [/location]

在寻找解决方案时，我遇到了这个问题，但运气不佳:

@Configuration
public class JacksonConfig {
    @Bean
    public Jackson2ObjectMapperBuilder jacksonBuilder() {
        Jackson2ObjectMapperBuilder b = new Jackson2ObjectMapperBuilder();
        b.modulesToInstall(new GeoJsonModule());
        return b;
    }
}

Spring boot 应用程序是:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

有人可以协助或提供任何指导吗？

我重新创建了整个场景，当 postman 调用电话时，GET 和 POST 都对我有用。您可以检查一下在服务器启动过程中是否收到以下行吗？

2018-09-03 15:10:41.995 INFO 17536 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping :映射“{[/location],methods=[POST],consumes=[application/json]}”到公共(public)com .example.demo.location.MyLocation com.example.demo.location.LocationController.recieveAddress(com.example.demo.location.MyLocation)

如果您看到这一行，则意味着您的方法已准备好可供访问。尝试使用以下配置使用 Postman 进行调用:https://pasteboard.co/HCba9qa.png

确保发布的数据如下所示:

{
    "location": {
        "type": "Point",
        "coordinates": [
            0.123321,
            0.3453455
        ]
    }
}

因为不需要发送 X 和 Y 坐标。我已经使用 MongoRepository 将这些数据保存在 MongoDB 中，它的作用就像一个魅力。如果您遇到任何问题，请告诉我。
