问题

我尝试在方法的请求参数中传递 LocalDateTime，但它始终记录为 null。请帮我找出我在这里做错了什么：

@Path("/book/workOrderId/{workOrderId}")
@PUT
public Response bookWorkOrder(@Context HttpHeaders headers, @PathParam("countryCode") String countryCode,
        @PathParam("workOrderId") int workOrderId,
        @QueryParam("reasonId") int reasonId,
        @RequestParam(value = "dateTime") @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss")  LocalDateTime dateTime

) throws CDException {

    logger.debug("dateTime outside if::" + dateTime);
    return Response.ok(true).build();
}

输出：

22:32:27.659 [http-nio-8300-exec-2] DEBUG c.c.t.i.e.v.impl.WorkorderController - dateTime outside if::null

I am trying to pass LocalDateTime in the request param of a method but it always logs null. Please help me figure out what I did wrong here:

@Path("/book/workOrderId/{workOrderId}")
@PUT
public Response bookWorkOrder(@Context HttpHeaders headers, @PathParam("countryCode") String countryCode,
@PathParam("workOrderId") int workOrderId,
@QueryParam("reasonId") int reasonId,
@RequestParam(value = "dateTime") @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss") LocalDateTime dateTime

) throws CDException {

	logger.debug("dateTime outside if::" + dateTime);
	return Response.ok(true).build();

}

Output:

22:32:27.659 [http-nio-8300-exec-2] DEBUG c.c.t.i.e.v.impl.WorkorderController - dateTime outside if::null

这对我有效：
```java
@PUT
public Response bookWorkOrder(@Context HttpHeaders headers, @PathParam("countryCode") String countryCode,
        @PathParam("workOrderId") int workOrderId, @QueryParam("bookingTime") String bookingTime,
        @QueryParam("reasonId") int reasonId) throws CDException {
    LocalDateTime localDateTime = LocalDateTime.parse(bookingTime, DateTimeFormatter.ISO_DATE_TIME);
    logger.debug("bookingTime:: {}", bookingTime);
    return Response.ok(true).build();
}

@PUT
	public Response bookWorkOrder(@Context HttpHeaders headers, @PathParam("countryCode") String countryCode,
			@PathParam("workOrderId") int workOrderId, @QueryParam("bookingTime") String bookingTime,
			@QueryParam("reasonId") int reasonId) throws CDException {
		LocalDateTime localDateTime = LocalDateTime.parse(bookingTime, DateTimeFormatter.ISO_DATE_TIME);
		logger.debug("bookingTime:: {}", bookingTime);
return Response.ok(true).build();

}
