加密url、用户名、密码、驱动类
public void generateJDBCString() {
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
encryptor.setAlgorithm(ParamEncryptor.ALGORITHM);
encryptor.setProvider(new BouncyCastleProvider());// none-JCE
encryptor.setPassword(ParamEncryptor.ALGORITHM_PASSWORD);
String driverClass = "org.mariadb.jdbc.Driver";
String url = "jdbc:mariadb://localhost:3306/mysql";
String username = "test";
String pwd = "123456";
String encryptDriverClass = encryptor.encrypt(driverClass);
String encryptUrl = encryptor.encrypt(url);
String encryptUsername = encryptor.encrypt(username);
String encryptPwd = encryptor.encrypt(pwd);
System.out.println("driver class: "+encryptDriverClass);
System.out.println("url: "+encryptUrl);
System.out.println("username: "+encryptUsername);
System.out.println("pwd: "+encryptPwd);
}自定义数据库连接池连接提供者DruidConnectionProvider，解密url、用户名、密码、驱动类

使用注解映射实体，Jasypt加解密数据
首先用一个@TypeDef注解来定义加密类型，这个注解可以在持久实体类中，或者在一个单独的package-info.java文件中的@TypeDefs声明中：
@TypeDef（
name =“encryptedString”，
typeClass = EncryptedStringType.class，
parameters = {
@Parameter（name =“encryptorRegisteredName”，value =“myHibernateStringEncryptor”）
} ）...然后简单地将我们的属性与已经声明的类型进行映射：
@Type（type =“encryptedString”）
public String getAddress（）{
return address;
