Java多线程实战-CompletableFuture异步编程优化查询接口响应速度

前言在Web应用开发中,一个界面可能需要同时请求多个接口来获取不同信息。传统的做法是编写一个聚合接口同步获取这些数据，第二种方法是分多次请求来获取数据。这两种方式虽然简单直观,但效率比较低下，随着应用复杂度的增加,这种低效的做法将会带来严重的性能问题。异步编程模型可以很好地解决这个问题。多个任务...

Java多线程Future与CompletableFuture-异步获取接口返回结果

背景：当调用一些耗时接口时，如果我们一直在原地等待方法返回，整体程序的运行效率会大大降低。可以把调用的过程放到子线程去执行，再通过 Future 去控制子线程的调用过程，最后获取到计算结果。提高整个程序的运行效率。创建线程池：@Configuration public class ExecutorC...
