timestamp转LocalDateTime

可以使用Timestamp类的toLocalDateTime()方法将Timestamp转换为LocalDateTime。以下是一个示例代码：

Timestamp timestamp = new Timestamp(System.currentTimeMillis());
LocalDateTime localDateTime = timestamp.toLocalDateTime();
System.out.println("LocalDateTime: " + localDateTime);```
输出：

LocalDateTime: 2021-10-20T16:23:45.123456

Timestamp转 LocalDateTime

在Java中，可以使用`Timestamp`类和`LocalDateTime`类相互转换。下面是一个示例代码：

import java.sql.Timestamp;
import java.time.LocalDateTime;

public class TimestampToLocalDateTimeExample {
    public static void main(String[] args) {
        // 将Timestamp转换为LocalDateTime
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        LocalDateTime localDateTime = timestamp.toLocalDateTime();
        System.out.println("Timestamp: " + timestamp);
        System.out.println("LocalDateTime: " + localDateTime);

        // 将LocalDateTime转换为Timestamp
        LocalDateTime localDateTime2 = LocalDateTime.now();
        Timestamp timestamp2 = Timestamp.valueOf(localDateTime2);
        System.out.println("LocalDateTime: " + localDateTime2);
        System.out.println("Timestamp: " + timestamp2);
    }
}

输出结果：

Timestamp: 2021-01-01 12:34:56.789
LocalDateTime: 2021-01-01T12:34:56.789
LocalDateTime: 2021-01-01T12:34:56.789
Timestamp: 2021-01-01 12:34:56.789

timestamp 转 localdatetime

可以使用Java中的Timestamp和LocalDateTime类来进行时间转换。具体方法如下：

// 引入相关类
import java.sql.Timestamp;
import java.time.LocalDateTime;
import java.time.Instant;

// 将Timestamp转为LocalDateTime
Timestamp timestamp = new Timestamp(System.currentTimeMillis());
LocalDateTime localDateTime = timestamp.toLocalDateTime();

// 将LocalDateTime转为Timestamp
LocalDateTime localDateTime = LocalDateTime.now();
Timestamp timestamp = Timestamp.valueOf(localDateTime);

其中，第一段代码将当前时间戳转为Timestamp对象，再通过toLocalDateTime()方法将其转为LocalDateTime对象；第二段代码则是将当前LocalDateTime对象转为Timestamp对象，使用valueOf()方法即可。
