想请教下WebConfig中的这段代码是啥意思

[Bender65535]

@PostConstruct
public void initEditableValidation() {
ConfigurableWebBindingInitializer configurableWebBindingInitializer = (ConfigurableWebBindingInitializer) requestMappingHandlerAdapter.getWebBindingInitializer();
if(configurableWebBindingInitializer.getConversionService() != null){
GenericConversionService service = (GenericConversionService) configurableWebBindingInitializer.getConversionService();
service.addConverter(new StringToDateConverter());
}
}

这是网上的代码，用来将时间戳往前端传的时候转化为时间的格式（yymmdd那种）
