1.配置文件中进行修改
1. jackson: 2. date-format: yyyy-MM-dd HH:mm:ss
这样序列化后，Date类型会被格式化成配置中的格式。
2.配置类中配置
创建JacksonConfig.java
@Configuration public class JacksonConfig { @Bean @Order(Ordered.HIGHEST_PRECEDENCE) public Jackson2ObjectMapperBuilderCustomizer customJackson() { return new Jackson2ObjectMapperBuilderCustomizer() { @Override public void customize(Jackson2ObjectMapperBuilder builder) { builder.serializerByType(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))); builder.serializerByType(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd"))); builder.serializerByType(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern("HH:mm:ss"))); builder.deserializerByType(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))); builder.deserializerByType(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd"))); builder.deserializerByType(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern("HH:mm:ss"))); builder.serializationInclusion(JsonInclude.Include.NON_NULL); builder.failOnUnknownProperties(false); builder.featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS); } }; } }
1、Springboot默认使用的json解析框架是jackson框架
2、jackson解析框架在解析实体类里面是Date数据类型的数据时的默认格式是：UTC类型，即yyyy-MM-dd’T’HH:mm:ss.SSS 并且默认为+8时区，即时间基础上加8小时
请求数据格式为： 'yyyy-MM-dd HH:mm:ss'，但是在接收到数据的时候，需要通过jackson把数据转化成Dto对象。jackson转化的时候，默认的时间格式是 'yyyy-MM-dd'T'HH:mm:ss.SSS’，
