升级内部框架版本后，发现Feign调用失败，报错如下：

Failed to convert value of type 'java.lang.String' to required type 'java.time.ZonedDateTime'; 
nested exception is org.springframework.core.convert.ConversionFailedException: 
	Failed to convert from type [java.lang.String] to type [@org.springframework.web.bind.annotation.RequestParam @org.springframework.format.annotation.DateTimeFormat java.time.ZonedDateTime] for value '2023/12/18 02:57'; 
	nested exception is java.lang.IllegalArgumentException: Parse attempt failed for value [2023/12/18 02:57]

客户端伪代码如下:

public interface FeignClient {

	@GetMapping("/")
	List<PlatformStandardOrderDto> test(
			@RequestParam ZonedDateTime startTime,
			@RequestParam ZonedDateTime endTime
	);

}

这个问题的现象是Feign调用时参数中的ZonedDatetime类型的时间格式化的结果服务端无法解析
