springboot DTO字符字段与日期字段的转换问题

public class UserDTO {
 private String name;
 private String email;
 private Boolean sex;
 private Double total;
 private BigDecimal totalMoney;
 private Date birthday;
}

{
 "email": null,
 "name": "lr",
 "total":3,
 "totalMoney":1,
 "birthday":"1983-03-18"
}

{
 "name": "lr",
 "email": null,
 "sex": null,
 "total": "3.00",
 "totalMoney": 0.0000,
 "birthday": 416793600000
}

public class UserDTO {
 private String name;
 private String email;
 private Boolean sex;
 private Double total;
 private BigDecimal totalMoney;
  @JsonFormat(pattern = "yyyy-MM-dd", timezone = "GMT+8")
 private Date birthday;
}

spring:
 jackson.date-format: yyyy-MM-dd
 jackson.time-zone: GMT+8
 jackson.serialization.write-dates-as-timestamps: false

Configuration
@EnableWebMvc //覆盖默认的配置
public class WebMvcConfigurerImpl implements WebMvcConfigurer {
 @Override
 public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
  MappingJackson2HttpMessageConverter jackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
  ObjectMapper objectMapper = new ObjectMapper();

  // 时间格式化
  objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
  objectMapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd"));//只能是一个日期格式化，多个会复盖
 }
}
