1.配置文件中进行修改
代码语言:javascript复制 jackson:
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
代码语言:javascript复制@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’,
