localdatetime转换成String

要LocalDateTime类型转换为String类型，可以使用DateTimeFormatter类的ofPattern方法指定日期格式，然后使用format方法将LocalDateTime对象格式化为字符串。以下是示例代码：

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

public class Main {
    public static void main(String[] args) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        LocalDateTime dateTime = LocalDateTime.now();
        String dateString = dateTime.format(formatter);
        System.out.println(dateString);
    }
}

在这个示例中，我们创建了一个DateTimeFormatter对象，并使用ofPattern方法指定日期格式（例如"yyyy-MM-dd HH:mm:ss"）。然后，我们获取当前的LocalDateTime对象，并使用format方法将其转换为字符串。最后，我们将字符串输出到控制台。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
