Springboot整合Hikari數據庫連接池，密碼加密

1.application.yml配置

spring:
  datasource:
    jdbcUrl: jdbc:mysql://127.0.0.1:3306/jby?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false
    username: root
    password: 'f687101570bae7ce4d313c2b4440f4ae'
    #自動提交
    auto-commit: true
    #最小連接
    minimum-idle: 100
    #最大連接
    maximum-pool-size: 200
    #最大空閑時間
    idle-timeout: 60000
    #連接池名
    pool-name: DatebookHikariCP
    #最大生命周期
    max-lifetime: 900000
    #連接超時時間
    connection-timeout: 15000
    #心跳檢測
    connection-test-query: SELECT 'x' FROM DUAL

2. 構建UmspscDataSource類，繼承HikariDataSource類

@Slf4j
public class UmspscDataSource extends HikariDataSource {
    private String passwordDis;
    /**
     * 密匙
     */
    private final static String PKEY ="1234565437892132";
    @Override
    public String getPassword(){

        if(StringUtils.isNotBlank(passwordDis)){return passwordDis;}
        String encPassword = super.getPassword();
        if(null==encPassword){
            return null;
        }
        log.info("數據庫密碼加解密，{"+encPassword+"}");
        try{
            //  密文解密，解密方法可以修改
            String key = HexUtil.encodeHexStr(PKEY);
            SymmetricCrypto aes = new SymmetricCrypto(SymmetricAlgorithm.AES, key.getBytes());
            passwordDis = aes.decryptStr(encPassword, CharsetUtil.CHARSET_UTF_8);
            return passwordDis;
        }catch (Exception e){
            log.error("數據庫密碼解密出錯，{"+encPassword+"}");
            log.error(LogUtil.e(e));
            throw new AppException("數據庫密碼解密失敗！", e);
        }
    }
}

3.初始化DataSource類

@Component
public class CommonBeanFactory {

    @Bean(name = "dataSource", autowire = Autowire.NO)
    @Primary
    @ConfigurationProperties(ignoreUnknownFields = false,prefix="spring.datasource")
    public HikariDataSource dataSource() {
        HikariDataSource druidDataSource = new UmspscDataSource();
        return druidDataSource;
    }
}

*******************************

構建密文

@Slf4j
public class Main {

    public static void main(String[] args) {
        //明文
        String content = "123456";
        //密匙
        String pkey = "1234565437892132";
        log.info("密匙:" + pkey);
        String key = HexUtil.encodeHexStr(pkey);
        //構建
        SymmetricCrypto aes = new SymmetricCrypto(SymmetricAlgorithm.AES, key.getBytes());

        //加密為16進制表示
        String encryptHex = aes.encryptHex(content);
        log.info("密文:" + encryptHex);
        //解密為字符串
        String decryptStr = aes.decryptStr(encryptHex, CharsetUtil.CHARSET_UTF_8);
        log.info("明文:" + decryptStr);
    }
}
