当你到手一台服务器后,你会干什么?
Just One?
Yes, One.
Nothing.
But, this is life.
看看我都会做啥吧。
需要的配置
项目需要对一批数据进行跑批,由于背靠Java,且时间有限,考虑到便利性直接使用了Java自带的stream API。
public static void main(String[] args) {
// 模拟数据
var stream = Stream.of(1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 16, 17, 18, 19, 20,
21, 22, 23, 24, 25, 26, 27, 28, 29, 30,
31, 32, 33, 34, 35, 36, 37, 38, 39, 40,
41, 42, 43, 44, 45, 46, 47, 48, 49, 50,
51, 52, 53, 54, 55, 56, 57, 58, 59, 60,
61, 62, 63, 64, 65, 66, 67, 68, 69, 70,
71, 72, 73, 74, 75, 76, 77, 78, 79, 80,
81, 82, 83, 84, 85, 86, 87, 88, 89, 90,
91, 92, 93, 94, 95, 96, 97, 98, 99, 100);
// 批处理数据
stream.parallel().forEach(i -> {
log.info("{} {} {}", Thread.currentThread().getName(), LocalDateTime.now(), i);
try {
// 前置处理
// ...
// 业务API Call
// ...
// 业务逻辑
// ...
// 后置处理
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
});
}
