- 创建或获取 SSL 证书
首先，你需要一个 SSL 证书。可以使用自签名证书进行本地开发。使用 Java 自带的 keytool 工具生成自签名证书。
生成自签名证书：
shell
keytool -genkeypair -alias myapp -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650此命令将生成一个 keystore.p12 文件，该文件包含自签名证书，证书有效期为10年。你将被提示输入一些信息（如密码、名称等）。
如何判断升成的是否有效：
shell
keytool -list -keystore keystore.p12 -storetype PKCS12
shell
keytool -genkeypair -alias myapp -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650
输入密钥库口令:
再次输入新口令:
您的名字与姓氏是什么?
[Unknown]: cloud
您的组织单位名称是什么?
[Unknown]: juhe
您的组织名称是什么?
[Unknown]: juhecn
您所在的城市或区域名称是什么?
[Unknown]: suzhou
您所在的省/市/自治区名称是什么?
[Unknown]: js
该单位的双字母国家/地区代码是什么?
[Unknown]: CN
CN=cloud, OU=juhe, O=juhecn, L=suzhou, ST=js, C=CN是否正确?
[否]: 是
正在为以下对象生成 2,048 位RSA密钥对和自签名证书 (SHA256withRSA) (有效期为 3,650 天):
CN=cloud, OU=juhe, O=juhecn, L=suzhou, ST=js, C=CN
keytool -list -keystore keystore.p12 -storetype PKCS12
输入密钥库口令:
密钥库类型: PKCS12
密钥库提供方: SUN
您的密钥库包含 1 个条目
myapp, 2024年9月5日, PrivateKeyEntry,
证书指纹 (SHA-256): 74:5D:37:8F:6B:D3:9C:04:F9:4D:97:C2:4D:1B:54:62:2B:10:2C:AE:CB:5E:A2:68:49:E6:34:88:BF:76:B5:89- 配置 Spring Boot 应用程序
接下来，你需要在 application.yml 或 application.properties 文件中配置 HTTPS。
如果使用 application.yml：
yml
server:
port: 8080
ssl:
key-store: /Users/java0904/bayarea/src/main/resources/keystore.p12
key-store-password: wei123
key-store-type: PKCS12
key-alias: myapp
enabled: true注意：这里的 key-store 写成绝对路径，不然启动报错
