How to use LocalDateTime RequestParam in Spring? I get “Failed to convert String to LocalDateTime”

Question

I use Spring Boot and included jackson-datatype-jsr310 with Maven:

    com.fasterxml.jackson.datatype

You did everything correct :) . Here is an example that shows exactly what you are doing. Just Annotate your RequestParam with @DateTimeFormat. There is no need for special GenericConversionService or manual conversion in the controller. This blog post writes about it.

@RestController
@RequestMapping("/api/datetime/")
final class DateTimeController {

    @RequestMapping(value = "datetime", method = RequestMethod.POST)
    public void processDateTime(@RequestParam("datetime") 
                                @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME) LocalDateTime dateAndTime) {
        //Do stuff
    }
}

I guess you had an issue with the format. On my setup everything works well.
