spring api heroku时区不工作吗？

Question

我有一个dto类有字段

    @Future(message = "Invalid Past Time")
    @DateTimeFormat(iso = DateTimeFormat.ISO.TIME)
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "hh:mm a")
    @JsonProperty(value = "time")
    private LocalTime reservationTime;

### when i run on my localhost works fine but when i deploy to heroku the time after deserialization become local time-2 hours   

我试过：

   @Future(message = "Invalid Past Time")
    @DateTimeFormat(iso = DateTimeFormat.ISO.TIME)
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "hh:mm a", timezone = "Africa/Cairo")
    @JsonProperty(value = "time")
    private LocalTime reservationTime;

但不是工作我也试过

 @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE, true);
        return mapper;
    }

我的问题在哪里?

请检查此示例，并添加这是数据源application.properties

spring.datasource.url=jdbc:mysql://localhost:8080/database_name?serverTimezone=UTC
