解决加载静态文件无法被浏览器缓存问题

开发环境是：nginx+spring boot + thymeleaf.
遇到的问题：js/css等静态资源文件不被浏览器缓存；如果是本地开发环境不会有这个问题。
解决方法是：nginx设置gzip和过期时间

nginx设置gzip：nginx.conf

gzip on; gzip_comp_level 6; # 压缩比例，比例越大，压缩时间越长。默认是1 gzip_types text/xml text/plain text/css application/javascript application/x-javascript application/rss+xml; # 哪些文件可以被压缩 gzip_disable "MSIE [1-6]\."; # IE6无效

nginx设置过期时间

server { listen 443 ssl; server_name yy.domain.com; ssl_certificate /usr/local/tomcatInstance/assistAdmin/cert/1.pem; ssl_certificate_key /usr/local/tomcatInstance/assistAdmin/cert/1.key; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; ssl_ciphers HIGH:!aNULL:!MD5; ssl_prefer_server_ciphers on; location ~* .(ico|gif|bmp|jpg|jpeg|png|swf|js|css) { proxy_pass https://yy; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; expires 30d; } }
