前言

没什么好讲的，用就完了

@JsonComponent
public class DateFormatConfig {
    @Value("${spring.jackson.date-format:yyyy-MM-dd HH:mm:ss}")
    private String pattern;

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilder() {
        return builder -> {
            TimeZone tz = TimeZone.getTimeZone("GMT+8");
            DateFormat df = new SimpleDateFormat(pattern);
            df.setTimeZone(tz);
            builder.failOnEmptyBeans(false)
                    .failOnUnknownProperties(false)
                    .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
                    .dateFormat(df);
        };
    }
}
