置信很多前端对接后段时间类型转换的问题，工夫格局不统一的问题，通过 jackson 也能够做到全局的配置，不在应用注解单个判断工夫类型

 引入的 maven

/// 配置自定义 model
public class LocalJavaTimeModule extends SimpleModule {public CustomJavaTimeModule() {super(PackageVersion.VERSION);
this.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
this.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
this.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));
this.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
this.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
this.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));

}

@Configuration
@ConditionalOnClass(ObjectMapper.class)
@AutoConfigureBefore(JacksonAutoConfiguration.class)
public class JacksonConfig {

@Bean
public Jackson2ObjectMapperBuilderCustomizer customizer() {
return builder -> {
/**
* 配置 Date 的格式化
*/
builder.locale(Locale.CHINA);
builder.timeZone(TimeZone.getTimeZone(ZoneId.systemDefault()));
builder.simpleDateFormat(DatePattern.NORM_DATETIME_PATTERN);
/**
* 配置 java8 工夫配置
*/
builder.modules(new LocalJavaTimeModule());
};
}
}

这样就能够了, 当然多模块能够做成一个插件 starter 之类的
