Configure Jackson instead using DateTimeFormat.ISO.DATE - not working

Question

I want to configure Jackson instead using DateTimeFormat.ISO.DATE every time when I'm requesting a date for example:

@RequestMapping(value = "income")
  public ResponseEntity calculateIncome(
      @RequestParam(value = "companyName") String companyName,
      @DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
      @RequestParam(value = "startDate") LocalDate startDate,
      @DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
      @RequestParam(value = "endDate") LocalDate endDate
  ) 

I've already tried setup it in JacksonConfig

mapper.enable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

or

mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

also

mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);

or

mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, true);

even in application.properties i tried

spring.jackson.serialization.write_dates_as_timestamps=true

I'm using spring-boot wit following dependencies

 <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
      <version>1.5.10.RELEASE</version>
    </dependency>
<dependency>
      <groupId>com.fasterxml.jackson.datatype</groupId>
      <artifactId>jackson-datatype-jsr310</artifactId>
      <version>${jackson.version}</version>
    </dependency>

I just don't want to repeat over and over the same @DataTimeFormat but without it, I'm still getting error:

SOLUTION: I Have found the solution here It's all about a custom editor for LocalDate and implementation of Formatter

@Bean
  public Formatter<LocalDate> localDateFormatter() {
    return new Formatter<LocalDate>() {
      @Override
      public LocalDate parse(String text, Locale locale) throws ParseException {
        return LocalDate.parse(text, DateTimeFormatter.ISO_DATE);
      }

      @Override
      public String print(LocalDate object, Locale locale) {
        return DateTimeFormatter.ISO_DATE.format(object);
      }
    };
  }
