【SpringBoot】中时间类型序列化、反序列化、格式处理

Date

yml全局配置

spring:

jackson:

time-zone: GMT+8

date-format: yyyy-MM-dd HH:mm:ss #配置POST请求Body中Date时间类型序列化格式处理，并返回

请求参数类型转换


/**
 * 时间Date转换
 * 配置GET请求，Query查询Date时间类型参数转换
 */
@Component
public class DateConverter implements Converter<String, Date> {
 @Override
 public Date convert(String source) {
 if (StringUtils.isBlank(source)) {
  return null;
 }
