代碼中注入一個bean即可:

  /**

     *
     * @return
     */
    @Bean("jackson2ObjectMapperBuilderCustomizer")
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        Jackson2ObjectMapperBuilderCustomizer customizer = jacksonObjectMapperBuilder -> jacksonObjectMapperBuilder.serializerByType(Long.class, ToStringSerializer.instance)
                .serializerByType(Long.TYPE, ToStringSerializer.instance);
        return customizer;
    }
