记接口优化经历

我是用Springboot开发的接口,刚开始接口相应速度在5-6s左右，优化后在2s以内。

1.Springboot配置

spring.mvc.servlet.load-on-startup=1

2.jdk优化

${jdk安装目录}\open-jdk-1.8.0_211_x64\jre\lib\security\java.security
securerandom.source=file:/dev/urandom
刚开始用的oracle得jdk1.8.0_144(windows端)/jdk1.8.0_144(Linux端),修改效果不大,
后都改用open-jdk-1.8.0_211 64位效果提升明显。

3.nginx优化

我的实战配置:

文件 nginx.conf
===========================================================
http{
    .....

    tcp_nodelay on;
    tcp_nopush on;
    sendfile on;
    keepallive_timeout 300;
    keepalive_requests 10000;
    include /usr/local/nginx/conf/conf.d/*.conf;
}

===========================================================
conf.d/xxx.conf
upsteam xxx-online{
    server ip:port weight=1 max_fails=2 fail_timeout=30s;
    server ip:port weight=1 max_fails=2 fail_timeout=30s;
    keepalive 1000;
}

server {
  listen port;
  server_name localhost;

  location / {
      proxy_pass http://xx-online;
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      add_header Cache-Control no-store;
      #1.1支持长连接 默认是1.0 不支持长连接
      proxy_http_version 1.1;
      proxy_set_header Connection "";
  }
}
