SpringBoot配置全局日期时间格式化

一、前端GET请求 params入参格式化

配置application.yml

spring:
  mvc:
    format:
      # 前端时间入参格式（GET请求 - params）
      date-time: yyyy-MM-dd HH:mm:ss

二、JSON入参出参格式化

编写配置类

import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateSerializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalTimeSerializer;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;
import java.util.TimeZone;

/**

@Configuration
public class DateTimeConfig {
    @Value("${spring.jackson.date-format:yyyy-MM-dd HH:mm:ss}")
    private String pattern;

    /**

     *
     * @return Jackson2ObjectMapperBuilderCustomizer
     */
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilder() {
        return builder -> {
            TimeZone timeZone = TimeZone.getTimeZone("UTC");
            DateFormat dateFormat = new SimpleDateFormat(pattern);
            dateFormat.setTimeZone(timeZone);
            builder.failOnEmptyBeans(false)
                    .failOnUnknownProperties(false)
                    .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
                    .dateFormat(dateFormat);
        };
    }

    /**
     * JSON序列化和反序列化转换器，用于转换body请求体/响应体中的JSON格式
     */
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> builder
                .serializerByType(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(pattern)))
                .serializerByType(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(pattern)))
                .serializerByType(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(pattern)))
                .deserializerByType(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(pattern)))
                .deserializerByType(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(pattern)))
                .deserializerByType(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(pattern)));
    }
}
