spring mvc中的@DateTimeFormat模式或jackson日期格式不起作用

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addFormatters(FormatterRegistry registry) {
        DateTimeFormatterRegistrar registrar = new DateTimeFormatterRegistrar();
        registrar.setUseIsoFormat(true);
        registrar.registerFormatters(registry);
    }
}

@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date date;

@Configuration
public class JacksonConfig {
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jsonCustomizer() {
        return builder -> {
            builder.simpleDateFormat("yyyy-MM-dd");
            builder.serializers(new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
            builder.serializers(new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
        };
    }
}

@Configuration
public class JacksonConfig {
    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd"));
        return objectMapper;
    }
}
