org.jasypt.exceptions.EncryptionOperationNotPossibleException

Question

I am using Jasypt-1.9.0 with Spring 3.1 and Hibernate 4.0.1. I have a requirement in my application to connect to database who

Answer 1

1. Remove all above XML configuration and add the following bean to your configuration class:

   @Bean public DataSource dataSource() {
   DataSourceBuilder dataSourceBuilder = 
   DataSourceBuilder.create();
   dataSourceBuilder.url(dbUrl);
   dataSourceBuilder.username(username);
   dataSourceBuilder.password(password);
   return dataSourceBuilder.build(); 
   }
   

2. Add values from properties like

   @Value("${db.driverclassname}")
   private String dbDriverClassName;
   
   @Value("${db.url}")
   private String dbUrl;
   
   @Value("${db.username}")
   private String dbUsername;
   
   @Value("${db.password}")
   private String dbPassword;
   

   And pass these values above the data source.

3. Configure your encryption key in properties file like#

   db.driverclassname=com.mysql.jdbc.Driver
   db.url=jdbc:mysql://localhost:3306/contactsdb
   db.username=contactsuser
   db.password=ENC(XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx
   +hNPrJyQT888=
   

4. Don't create your encrypted key using cmd and jaspyt jar I will share the link for creating encryption key with your secret key:

   Jasypt Online Encryption and Decryption

5. Add jaspyat dependency as per your version.

   If you have to run on a server and if you are facing issues like password encryption not matches or not possible, then add one more bean of jdbc template:

   @Bean
   public JdbcTemplate jdbcTemplate(DataSource 
   dataSourcee)
   {
       return new JdbcTemplate(dataSource);
   }
   

It works fine and no issues found.

Create the key using that tool. Because I have tried many times using jaspyt command line but the encryption is wrong and it is not supported. You can cross-check key generated using the above tool with the secret key.
