Cara SpringBoot+nginx melaksanakan fungsi muat naik sumber-javaTutorial-php.cn

Pemasangan dan konfigurasi 1.nginx

Pelayan yang saya gunakan ialah pelayan aplikasi ringan Alibaba Cloud, dan sistem menggunakan Ubuntu. Ingat untuk membuka port 9090tcp Jika anda tidak menggunakan port 9090 sebagai port pelayan, anda tidak perlu menggunakannya.

Pemasangan

Pertama sekali, adalah perlu untuk mendapatkan pakej pemasangan Berikut ialah nginx-1.11.3-ubuntu.tar.gz https://pan .baidu .com/s/1vvb41qkoj4vqfyfckxbkja (kata laluan 45wz)

Editor meletakkan pakej pemasangan dalam /usr/nginx, memasuki direktori dan melaksanakan tar -zxvf nginx-1.11.3.tar.gz untuk menyahmampat konfigurasi

Ubah suai /usr/nginx/conf/nginx.conf:

server {
 listen  9090;
 server_name localhost;

 location ~ .(jpg|png|jpeg|gif|bmp)$ { #可识别的文件后缀
 root /usr/nginx/image/; #图片的映射路径
  autoindex on; #开启自动索引
 expires 1h; #过期时间
 }
 location ~ .(css|js)$ {
  root /usr/nginx/static/;
  autoindex on;
  expires 1h;
 } 
 location ~ .(avi|mov|rmvb|rm|flv|mp4|3gp)$ {
  root /usr/nginx/video/;
  autoindex on;
  expires 1h;
 }

Salin selepas log masuk

Ubah suai apa yang patut diubah, tambah apa yang perlu ditambah, ingat jangan padam secara rawak

Langkah terakhir , mulakan nginx dan jalankan ./usr/nginx/sbin/nginx

Pada ketika ini pelayan nginx sudah sedia

Anda boleh cuba memuat turun imej 01.jpg ke /usr /nginx/image , dan kemudian lihat jika imej boleh diakses secara setempat

Cara SpringBoot+nginx melaksanakan fungsi muat naik sumber

Perhatian ：

1. Jika anda ingin memuat naik video bersama-sama dengan imej, cuma ubah suai fail konfigurasi nginx.conf dan tambahkan akhiran video yang sepadan dan ia akan diletakkan dalam /usr/image selepas dimuat naik Jika tidak, fail boleh dimuat naik tetapi tidak boleh diakses

2. Antara muka muat naik kod di atas adalah untuk melaksanakan pelbagai muat naik fail
