Spring Boot Rest 中的枚举作为请求参数

我是 Spring Boot 新手，并尝试使用 Enum 作为休息请求的参数。

这是我的枚举类：

public enum Month {

    JANUARY (1, "january"), FEBRUARY(2,"february"), MARCH(3,"march"),
    APRIL(4,"april"), MAY(5,"may"), JUNE(6,"june"), JULY(7,"july"),
    AUGUST(8, "august"), SEPTEMBER(9,"september"), OCTOBER(10,"october"),
    NOVEMBER(11,"november"), DECEMBER(12,"december");

    private String desc;
    private int id;

    //Constructure

    //Getters and Setters
}

在我的控制器类中，我使用这种方法：

    @RequestMapping(value = "/testmonth", method = RequestMethod.POST)
        public Month TestForMonth(@RequestBody Month inputPayload) {
            Month response = inputPayload;
            response.setId(inputPayload.getId());
            response.setDesc(inputPayload.getDesc());
            System.out.println("As String: " + inputPayload.getDesc() + ". As int " + inputPayload.getId() + ".");
            return response;
        }

这是我的 JSON：

{
    Month: "JANUARY"
}

但它不起作用..我收到此错误：

.w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of `com.example.simplerestapis.models.Month` out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `com.example.simplerestapis.models.Month` out of START_OBJECT token

您的主体被声明为简单枚举类型，而不是对象。因此，不要发布带有大括号的 JSON 对象，而是尝试仅发布一个值，例如：

"JANUARY"
