Spring Security Authorized Access

In this section, you will learn about authorized access through Spring Security.

EXAMPLE

Sometimes you need to secure your page from unauthorized access. Authorized access is the secure access of page through a permitted username and password. For example, the admin section page can only have permission for admin only.

In the below example, we will ensure secure URL access by providing  auto generated Login form using Spring Security. User needs to provide correct login credential to view the page. For accessing admin section, you need to provide admin login and password. While for user section, both admin and user login are permitted.

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

You can implement user authenticity(in spring-security.xml ) as follows :

<http auto-config="true">
	<intercept-url pattern="/admin*" access="ROLE_ADMIN" />
		<logout logout-success-url="/admin" />
	<intercept-url pattern="/index*" access="ROLE_USER,ROLE_ADMIN" />
		<logout logout-success-url="/index" />
</http>

It means the user with authority as ROLE_ADMIN can have access to URL /admin . Also, the URL /index is open for both type of users having authority ROLE_USER or ROLE_ADMIN .

The project structure and jar file used is given below :
