You need to use a formatter to parse single character day/month fields for java.time.LocalDate
您需要使用格式化程序来解析单个字符的日/月字段 java.time.LocalDate
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-M-d");
LocalDate date = LocalDate.parse("2016-2-2", formatter);

LocalDate simply can't parse that string. Use SimpleDateFormat instead: https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
LocalDate 根本无法解析该字符串。改用 SimpleDateFormat：https: //docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
