blocks|key|194152|text|好了，我解决了。写给那些在一整天不停的编码后可能感到疲倦的人&怀念这样一件愚蠢的事情。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|194153|@RequestMapping(value="/fetch"+,+method=RequestMethod.GET)

Ok, I solved it.
Writing it for anyone who might be tired after a full day of non-stop coding &amp; miss such a silly thing.

<pre><code>@RequestMapping(value="/fetch" , method=RequestMethod.GET)
 public @ResponseBody String fetchResult(@RequestParam("from") @DateTimeFormat(pattern="yyyy-MM-dd") Date fromDate) {
 //Content goes here
 }
</code></pre>

Yes, it's simple. Just add the DateTimeFormat annotation.

blocks|key|2822857|text|这就是我从前端获取格式化日期的方法|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2822858|++@RequestMapping(value+=+"/{dateString}",+method+=+RequestMethod.GET)
++@ResponseBody
++public+HttpStatus+getSomething(@PathVariable+@DateTimeFormat(iso+=+DateTimeFormat.ISO.DATE)+String+dateString)+{

This is what I did to get formatted date from front end

<pre><code> @RequestMapping(value = "/{dateString}", method = RequestMethod.GET)
 @ResponseBody
 public HttpStatus getSomething(@PathVariable @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) String dateString) {
 return OK;
 }
</code></pre>

You can use it to get what you want.

blocks|key|2822869|text|..。或者你可以用正确的方式来做这件事，并且有一个连贯的规则来序列化/反序列化整个应用程序中的日期。将此代码放入application.properties：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2822870|spring.mvc.date-format=yyyy-MM-dd|code-block|syntax|javascript|2822871|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

... or you can do it the right way and have a coherent rule for serialisation/deserialisation of dates all across your application. put this in application.properties:

<pre><code>spring.mvc.date-format=yyyy-MM-dd
</code></pre>

blocks|key|2822909|text|下面的解决方案非常适合spring+boot应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2822910|控制器：|offset|length|style|BOLD|2822911|@GetMapping("user/getAllInactiveUsers")

Below solution perfectly works for spring boot application.

Controller:

<pre><code>@GetMapping("user/getAllInactiveUsers")
List&lt;User&gt; getAllInactiveUsers(@RequestParam("date") @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date dateTime) {
 return userRepository.getAllInactiveUsers(dateTime);
}
</code></pre>

So in the caller (in my case its a web flux), we need to pass date time in this("yyyy-MM-dd HH:mm:ss") format.

Caller Side:

<pre><code>public Flux&lt;UserDto&gt; getAllInactiveUsers(String dateTime) {
 Flux&lt;UserDto&gt; userDto = RegistryDBService.getDbWebClient(dbServiceUrl).get()
 .uri("/user/getAllInactiveUsers?date={dateTime}", dateTime).retrieve()
 .bodyToFlux(User.class).map(UserDto::of);
 return userDto;
}
</code></pre>

Repository:

<pre><code>@Query("SELECT u from User u where u.validLoginDate &lt; ?1 AND u.invalidLoginDate &lt; ?1 and u.status!='LOCKED'")
List&lt;User&gt; getAllInactiveUsers(Date dateTime);
</code></pre>

Cheers!!

If you want to use a PathVariable, you can use an example method below (all methods are and do the same):

<pre><code>//You can consume the path .../users/added-since1/2019-04-25
@GetMapping("/users/added-since1/{since}")
public String userAddedSince1(@PathVariable("since") @DateTimeFormat(pattern = "yyyy-MM-dd") Date since) {
 return "Date: " + since.toString(); //The output is "Date: Thu Apr 25 00:00:00 COT 2019"
}

//You can consume the path .../users/added-since2/2019-04-25
@RequestMapping("/users/added-since2/{since}")
public String userAddedSince2(@PathVariable("since") @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) Date since) {
 return "Date: " + since.toString(); //The output is "Date: Wed Apr 24 19:00:00 COT 2019"
}

//You can consume the path .../users/added-since3/2019-04-25
@RequestMapping("/users/added-since3/{since}")
public String userAddedSince3(@PathVariable("since") @DateTimeFormat(pattern = "yyyy-MM-dd") Date since) {
 return "Date: " + since.toString(); //The output is "Date: Thu Apr 25 00:00:00 COT 2019"
}

I've a GET request that sends a date in YYYY-MM-DD format to a Spring Controller.
The controller code is as follows:

<pre><code>@RequestMapping(value="/fetch" , method=RequestMethod.GET)
 public @ResponseBody String fetchResult(@RequestParam("from") Date fromDate) {
 //Content goes here
 }
</code></pre>

The request is sent correctly as I'm checking with Firebug.
I get the error:

<blockquote>
 HTTP Status 400: The request sent by the client was syntactically incorrect.
</blockquote>

How can I make the controller accept this format of Date? 
Please help. What am I doing wrong?
