Java 中 String 转 LocalDateTime 出现错误

场景

在 Java 中使用 LocalDateTime 解析 String 失败，代码如下

final LocalDateTime result = LocalDateTime.parse("2000-01-01", DateTimeFormatter.ofPattern("yyyy-MM-dd"));
log.info("result: {}", result);

把字符串转换为localDateTime

final DateTimeFormatter formatter = new DateTimeFormatterBuilder()
    .appendPattern("yyyy-MM-dd[['T'hh][:mm][:ss]]")
    .parseDefaulting(ChronoField.HOUR_OF_DAY, 0)
    .parseDefaulting(ChronoField.MINUTE_OF_HOUR, 0)
    .parseDefaulting(ChronoField.SECOND_OF_MINUTE, 0)
    .parseDefaulting(ChronoField.MILLI_OF_SECOND, 0)
    .toFormatter();
final LocalDateTime localDateTime = LocalDateTime.parse("2018-12-11", formatter);

使用  

 @InitBinder
    protected void initBinder(WebDataBinder binder) {

final DateTimeFormatter formatter = new DateTimeFormatterBuilder()
    .appendPattern("yyyy-MM-dd[['T'hh][:mm][:ss]]")
    .parseDefaulting(ChronoField.HOUR_OF_DAY, 0)
    .parseDefaulting(ChronoField.MINUTE_OF_HOUR, 0)
    .parseDefaulting(ChronoField.SECOND_OF_MINUTE, 0)
    .parseDefaulting(ChronoField.MILLI_OF_SECOND, 0)
    .toFormatter();

        binder.registerCustomEditor(LocalDate.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(LocalDate.parse(text, DateTimeFormatter.ofPattern("yyyy-MM-dd")));
            }
        });
        binder.registerCustomEditor(LocalDateTime.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {//text = "2018-12-11"

final LocalDateTime localDateTime = LocalDateTime.parse(text, formatter);
                setValue(localDateTime );
            }
        });
        binder.registerCustomEditor(LocalTime.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(LocalTime.parse(text, DateTimeFormatter.ofPattern("HH:mm:ss")));
            }
        });
    }
