Question

我对Spring控制器和ajax有一些奇怪的问题。当我尝试使用ajax将JSON对象传递给它时，Controller方法返回404。

这是我的代码：

@Data
@Builder
@JsonAutoDetect
public class Car {
    private int gears;
    private String color;
}

@Slf4j
@RestController
public class Test {

    @PostMapping("/ajaxJsonPost")
    public @ResponseBody HttpEntity<Car> samochod(@RequestBody Car car) {
        return new ResponseEntity<>(Car.builder().color(car.getColor()).gears(car.getGears()).build(), HttpStatus.OK);
    }

    @RequestMapping(value = "/ajaxJsonPost", method = RequestMethod.GET)
    public HttpEntity<Car> samochod() {
        return new ResponseEntity<>(Car.builder().color("blue").gears(1).build(), HttpStatus.OK);
    }
}

我发送带有python代码的ajax：

def main():
    app_url = 'http://localhost:8888/ajaxJsonPost'

    session = requests.Session()
    data = {'car': {'gears': 1,
                    'color': 'blue'}}
    response = session.post(url=app_url, data=data)
    # response = session.get(url=app_url)
    print(response)
    print(response.content)


if __name__ == "__main__":
    main()

您应该将应用程序的上下文添加到ajax调用

def main():
    app_url = 'http://localhost:8888/YOUR_APP_CONTEXT/ajaxJsonPost'
