Spring Security customized login from database

In this section, you will learn how to secure URL access using customized login where password stored in database table.

EXAMPLE

In the below example, we have created a customized login page but the login is checked from the database table. We have added spring-datasource.xml, to configure database with the application.

The tools and technologies used in the below example is given below :

  • jdk1.6.0_18

  • apache-tomcat-6.0.29

  • Eclipse 3.5.1

  • Spring 3.0.5.RELEASE

  • Spring Security 3.0.5.RELEASE

The project structure and jar files used are given below :

The query used to create the database table logins is given below :

CREATE TABLE `logins` ( 
`LOGIN_ID` int(10) unsigned NOT NULL, 
`USERNAME` varchar(45) NOT NULL, 
`PASSWORD` varchar(45) NOT NULL, 
`ENABLED` tinyint(1) NOT NULL, 
PRIMARY KEY (`LOGIN_ID`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1

We need the following record  in our example :

The query used to create the database table roles is given below :

CREATE TABLE `roles` ( 
`ROLE_ID` int(10) unsigned NOT NULL, 
`LOGIN_ID` int(10) unsigned NOT NULL, 
`ROLE` varchar(45) NOT NULL, 
PRIMARY KEY (`ROLE_ID`), 
KEY `FK_roles` (`LOGIN_ID`), 
CONSTRAINT `FK_roles` FOREIGN KEY (`LOGIN_ID`) REFERENCES `logins` (`LOGIN_ID`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1

We need the following record  in our example :

spring-security.xml

In spring-security.xml, we have added <jdbc-user-service> tag .. The data-source-ref of <jdbc-user-service> tag is used to refer to the "dataSource" bean used in spring-datasource.xml to configure the database table. Authentication manager uses the added SQL query to <jdbc-user-service> tag  to check the authority and login credential from the database table.
