@Configuration
public class AppConfig {
    @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")));
        };
    }
}

public class User {
    private String name;
    private LocalDate birthDate;
    // getters and setters
}

@RestController
public class UserController {
    @PostMapping("/users")
    public void createUser(@RequestBody User user) {
        // 处理用户创建逻辑
    }
}
