Springboot整合Hikari数据库连接池，密码加密

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'
     #自动提交
     auto-commit: true
     #最小连接
     minimum-idle: 100
     #最大连接
     maximum-pool-size: 200
     #最大空闲时间
     idle-timeout: 60000
     #连接池名
     pool-name: DatebookHikariCP
     #最大生命周期
     max-lifetime: 900000
     #连接超时时间
     connection-timeout: 15000
     #心跳检测
     connection-test-query: SELECT 'x' FROM DUAL

2. 构建UmspscDataSource类，继承HikariDataSource类

 @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("数据库密码加解密，{"+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("数据库密码解密出错，{"+encPassword+"}");
             log.error(LogUtil.e(e));
             throw new AppException("数据库密码解密失败！", e);
         }
     }
 }

3.初始化DataSource类

 @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;
     }
 }

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

构建密文

 @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);
         //构建
         SymmetricCrypto aes = new SymmetricCrypto(SymmetricAlgorithm.AES, key.getBytes());

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