复制keystore到springboot资源目录，修改application.yml配置
ssl:
key-store: classpath:cert.keystore
key-store-password: '!QAZ2wsx'
key-store-type: JKS
enabled: true
启动项目
nginx配置
开启ssl
server {
listen 443 ssl;
server_name localhost;
ssl_certificate /Users/fanshaorong/Desktop/Program/ssl/cert.pem;
ssl_certificate_key /Users/fanshaorong/Desktop/Program/ssl/cert.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;

location / {

location ~ /test-api {

}
}
server {
listen 81;
server_name localhost;
return 301 https://$host$request_uri;
#rewrite ^(.*)$ https://$host$1 permanent;
}
重启nginx -s reload
访问localhost:81将跳转到https://localhost/login?redirect=/index
