乔达DateTimeFormatter - 的方法ofPattern（字符串）是未定义

我试图解析日期LocalDateTime。输入日期-

{
    "meetingTitle":"Test",
    "fromTime":"2018-10-30 12:44",
    "toTime":"2018-10-30 12:44"
}

和POJO -

private String meetingTitle;
@DateTimeFormat(iso = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"))
@JsonFormat(pattern = "YYYY-MM-dd HH:mm")
private LocalDateTime fromTime;
@DateTimeFormat(iso = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"))
@JsonFormat(pattern = "YYYY-MM-dd HH:mm")
private LocalDateTime toTime;

但是我得到这个编译错误

The method ofPattern(String) is undefined for the type DateTimeFormatter

进口 -

import org.joda.time.LocalDateTime;
import org.joda.time.format.DateTimeFormatter;
import org.springframework.format.annotation.DateTimeFormat;

import com.fasterxml.jackson.annotation.JsonFormat;

难道我错过了一些例子？
