多个配置WebMvcConfigurationSupport失效问题

最近在项目中用类继承WebMvcConfigurationSupport实现拦截器

@Configuration
@RequiredArgsConstructor
public class SpringWebSupport extends WebMvcConfigurationSupport {private final ProjectInterceptor projectInterceptor;//    拦截器
//设置拦截器对象和拦截请求@Overrideprotected void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(projectInterceptor).addPathPatterns("
/**").excludePathPatterns("......"); //配置拦截路径}
}

同时呢，在我曾经写过的一个依赖包里(其他包)，配置了一个消息转换器并且在项目中引入

public class JacksonObjectMapper extends ObjectMapper{public static final String DEFAULT_DATE_FORMAT = "yyyy-MM-dd";public static final String DEFAULT_DATE_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss";public static final String DEFAULT_TIME_FORMAT = "HH:mm:ss";public JacksonObjectMapper () {super();//收到未知属性时不报异常this.configure(FAIL_ON_UNKNOWN_PROPERTIES, false);//反序列化时，属性不存在的兼容处理this.getDeserializationConfig().withoutFeatures(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);SimpleModule simpleModule = new SimpleModule().addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT))).addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT))).addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT))).addSerializer(BigInteger.class, ToStringSerializer.instance).addSerializer(Long.class, ToStringSerializer.instance)  // 对于long类型转为String.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT))).addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT))).addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT)));//注册功能模块 例如，可以添加自定义序列化器和反序列化器this.registerModule(simpleModule);}
}

@Slf4j
@Configuration
public class MyWebConfig extends WebMvcConfigurationSupport {/*** 扩展 mvc 框架的消息转换器* @param converters*/@Overrideprotected void extendMessageConverters(List<HttpMessageConverter<?>> converters) {// 创建消息转换器对象MappingJackson2HttpMessageConverter messageConverter = new MappingJackson2HttpMessageConverter();// 设置该消息转换器使用 JacksonObjectMapper 进行转换messageConverter.setObjectMapper(new  JacksonObjectMapper());// 将消息转换器对象追加到 mvc 框架的转换器集合中(加到最前面)converters.add(0, messageConverter);}
}

在启动类扫描了这另一个包里的WebMvcConfigurationSupport配置依赖。

希望的是：拦截器+消息转变换器全都生效，但是生效的只有拦截器，Long类型还是没有转换成String返回给前端。
