关于java:jackson全局配置解析localDateTime

• 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  <dependency> <groupId>cn.hutool</groupId> <artifactId>hutool-all</artifactId> <hutools.version>5.5.1</hutools.version></dependency>

///配置自定义modelpublic 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 {@Beanpublic 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
