java状态码枚举类

以下是一个Java状态码枚举类的例子：

public enum HttpStatus {
    OK(200, "OK"),
    BAD_REQUEST(400, "Bad Request"),
    UNAUTHORIZED(401, "Unauthorized"),
    FORBIDDEN(403, "Forbidden"),
    NOT_FOUND(404, "Not Found"),
    INTERNAL_SERVER_ERROR(500, "Internal Server Error"),
    SERVICE_UNAVAILABLE(503, "Service Unavailable");

    private final int code;
    private final String reason;

    HttpStatus(int code, String reason) {
        this.code = code;
        this.reason = reason;
    }

    public int getCode() {
        return code;
    }

    public String getReason() {
        return reason;
    }
}

这个枚举类定义了一些常见的HTTP状态码，包括状态码的数字代码和原因短语。你可以使用这个枚举类来表示HTTP响应的状态码，例如：

HttpStatus status = HttpStatus.OK;
int code = status.getCode(); // 200
String reason = status.getReason(); // "OK"
