HttpComponentsClientHttpRequestFactory-CSDN博客

HttpComponentsClientHttpRequestFactory HttpComponentsClientHttpRequestFactory 是 Spring Framework 中用来封装 Apache HttpComponents HttpClient 的一个工厂类，用于创建基于 HttpClient 的 ClientHttpRequest 实例。然而，关于默认的最大连接数，这个信息通常是由底层使用的 Apache HttpClient 的配置决定的，而不是由 HttpComponentsClientHttpRequestFactory 类本身直接设定。 Apache HttpClient 默认的最大连接数（即最大并发连接数）通常取决于所使用的 HttpClient 版本以及具体的连接管理器（Connection Manager）实现。在 HttpClient 4.x 及以上版本中，最常用的连接管理器是 PoolingHttpClientConnectionManager。 对于...

A Ride Through Optimising Legacy Spring Boot Services For High Throughput

A Ride Through Optimising Legacy Spring Boot Services For High Throughput Oops! Did I fix it or screw it up for real? Even though we could easily scale this system up either vertically and/or horizontally as desired and the load tested was 20x the expected peek, the rate of failed responses on our load tests before my quest was about 8%. 8% for me is a lot! 8% of €1.000.000.000.000,00 is a lot of money for me (maybe not for Elon Musk).

优化 HttpClient，轻松提升高并发场景下的 QPS！

2024-01-05 08:23:55 项目的原实现比较粗略，就是每次请求时初始化一个httpclient，生成一个httpPost对象，执行，然后从返回结果取出entity，保存成一个字符串，最后显式关闭response和client。 我们有个业务，会调用其他部门提供的一个基于http的服务，日调用量在千万级别。使用了httpclient来完成业务。之前因为qps上不去，就看了一下业务代码，并做了一些优化，记录在这里。 先对比前后：优化之前，平均执行时间是250ms； 优化之后，平均执行时间是80ms，降低了三分之二的消耗，容器不再动不动就报警线程耗尽了，清爽~ 1.分析 项目的原实现比较粗略，就是每次请求时初始化一个httpclient，生成一个httpPost对象，执行，然后从返回结果取出entity，保存成一个字符串，最后显式关闭response和client。 我们一点点分析和优化： httpclient是一个线程安全的类，没有必要由每个线程在每次使用时创建，全局保留一个即可。...
