很多时候日期格式输出是这样的  2018-10-09T17:39:07.097 中间有个T,尴尬,是的我们需要去掉这个T 这方法是springboot封装好了的,我们直接使用即可,普通的配置我就不贴了

创建日期config类

/**
 * 关于Java8中localDateTime去掉中间的T
 */
@Configuration
public class LocalDateTimeSerializerConfig {
    @org.springframework.beans.factory.annotation.Value("${spring.jackson.date-format:yyyy-MM-dd HH:mm:ss}")
    private String pattern;
    @Bean
    public LocalDateTimeSerializer localDateTimeDeserializer() {
        return new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(pattern));
    }
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> builder.serializerByType(LocalDateTime.class, localDateTimeDeserializer());
    }
}
