spring hibernate encrypted password

In this section, you will learn about encrypted password in spring hibernate.

In the below example, we will save the password in the encrypted format(md5).

EXAMPLE

The project structure is given below :

The jar files used are given below :

The SQL query used to create user table is given below :

CREATE TABLE `user` ( 
	`user_id` bigint(11) NOT NULL auto_increment, 
	`user_name` varchar(100) default NULL, 
	`user_email` varchar(100) default NULL, 
	`password` varchar(100) NOT NULL, 
	`gender` varchar(1) default NULL, 
	`phone_no` varchar(30) default NULL, 
	`address` text, 
	PRIMARY KEY (`user_id`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1
