无法在索引0处分析Java LocalDateTime文本异常

Question

private DateTimeFormatter dateFormat = DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm");
private String caseStartDate = dateFormat.format(LocalDateTime.now());

LocalDateTime localdatetime = LocalDateTime.parse(caseStartDate);

Answer 1

您需要在LocalDateTime：：Parse中使用格式，如下所示：

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

class Main {
    public static void main(String[] args) {
        DateTimeFormatter dateFormat = DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm");
        String caseStartDate = dateFormat.format(LocalDateTime.now());
        System.out.println(caseStartDate);
        LocalDateTime localdatetime = LocalDateTime.parse(caseStartDate, dateFormat);
        System.out.println(localdatetime);
    }
}

另外，请参阅如何重写LocalDateTime的toString()方法：

@Override
public String toString() {
    return date.toString() + 'T' + time.toString();
}
