本文整理了Java中java.time.LocalDateTime.of()方法的一些代码示例，展示了LocalDateTime.of()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。LocalDateTime.of()方法的具体详情如下：
包路径：java.time.LocalDateTime
类名称：LocalDateTime
方法名：of

LocalDateTime.of介绍

[英]Obtains an instance of LocalDateTime from year, month, day, hour and minute, setting the second and nanosecond to zero.

The day must be valid for the year and month, otherwise an exception will be thrown. The second and nanosecond fields will be set to zero.
[中]从年、月、日、小时和分钟获取LocalDateTime的实例，将秒和纳秒设置为零。
日期必须对年和月有效，否则将引发异常。第二个和纳秒字段将设置为零。
