springboot对数据库密码加密

使用com.alibaba.druid.filter.config.ConfigTools生成公私钥和密码

public class DataPassword {
    public static void main(String[] args) throws Exception {
        //密码明文
        String password = "123456";
        System.out.println("明文密码: " + password);
        String[] keyPair = ConfigTools.genKeyPair(512);
        //私钥
        String privateKey = keyPair[0];
        //公钥
        String publicKey = keyPair[1];

        //用私钥加密后的密文
        password = ConfigTools.encrypt(privateKey, password);

        System.out.println("privateKey:" + privateKey);
        System.out.println("publicKey:" + publicKey);

        System.out.println("password:" + password);

        String decryptPassword = ConfigTools.decrypt(publicKey, password);
        System.out.println("解密后:" + decryptPassword);


    }
}

配置文件配置

pkg.datasource.password=加密后的密码
pkg.datasource.publicKey=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAJRtLhqdJ+oFUWz/H/KMHYcJJkPg/VRV0QcLq7EBVeggQaNPhRQqLwtseiKl0XbUhSlnpyiOeJ+7pHe8M770ZzECAwEAAQ==
spring.datasource.druid.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000;config.decrypt=true;config.decrypt.key=@pkg.datasource.publicKey@
