WebMvcConfig 全局設置時間服務器時區

@Override public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {MappingJackson2HttpMessageConverter jackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();ObjectMapper objectMapper = jackson2HttpMessageConverter.getObjectMapper();//json中多余的參數不報錯，不想要可以改掉objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);//設置全局的時間轉化

// SimpleDateFormat smt = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);
// objectMapper.setDateFormat(smt);
// objectMapper.setTimeZone(TimeZone.getTimeZone(“GMT+”+getTimeZone()));//解決時區差8小時問題

objectMapper.setTimeZone(TimeZone.getTimeZone("GMT+"+ DateUtil.getTimeZone()));//解決時區差8小時問題jackson2HttpMessageConverter.setObjectMapper(objectMapper);converters.add(0, jackson2HttpMessageConverter);

public static String getTimeZone(){
Calendar cal = Calendar.getInstance();
int offset = cal.get(Calendar.ZONE_OFFSET);
cal.add(Calendar.MILLISECOND, -offset);
Long timeStampUTC = cal.getTimeInMillis();
Long timeStamp = System.currentTimeMillis();
Long timeZone = (timeStamp - timeStampUTC) / (1000 * 3600);
System.out.println(String.valueOf(timeZone));
return String.valueOf(timeZone);

}
