Get Value from URL parameter with GetMapping ~ LocalDate ~

――I'm posting it as my own memo.

URL：http://localhost:8080/date/2018-02-02/2019-01-01 --Important cousin --No. 1. Match the URL pattern (this time: 2018-02-02)
1. @DateTimeFormat(pattern = "yyyy-MM-dd")
2. @PathVariable LocalDate from
3. @PathVariable LocalDate to

@RestController
@RequestMapping(value = "/date/{from}/{to}", method = RequestMethod.GET)

public class CsvController {

    @GetMapping
    public String get(@DateTimeFormat(pattern = "yyyy-MM-dd") @PathVariable LocalDate from,
                      @DateTimeFormat(pattern = "yyyy-MM-dd") @PathVariable LocalDate to) {
        return "fromDate:" + from.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"))
               + "toDate:" + to.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
    }
}
