Securing Your Java Applications – Acegi Security Style

The first one determines whether or not access should be granted if all AccessDecisionVoters abstain. Prior to acwgi to the resource, interception determines whether or not the resource should be protected. There are a number of ways to perform authentication for web applications. In the next part of this, we will introduce more advanced features, such as Spring-based AOP functionality for protecting business object and access control list ACL functionality for domain object instance security.

Therefore, security is often one of the most important aspects. Update company role to: Based upon the result, the interceptor either allows the request or not. Subscribe to our industry email notices? The second object securityy the credentials that provide proof of the identity of the caller.

Join the DZone community and get the full member experience. Project founder Ben Alex announced the launch on the SpringFramework forums: While this article and the next installment gives the reader a running start to integrating Acegi, a number of configuration options and features have been excluded. This article assumes the user is vaguely familiar with Spring XML configuration. Get the most out of the InfoQ experience. While the above interfaces are important, especially to developers creating custom authentication mechanisms for Acegi, the primary value for most is an understanding of the authentication chain.


If authentication fails, the browser will automatically be redirected to the URL specified by authenticationFailureUrl. For example, a web application presents the user with a prompt for username and password.

Pathway from ACEGI to Spring Security 2.0

This provider is easy to understand, configure, and demonstrate. The Authentication interface which holds three important objects. This short guide on how to configure Spring Security 2. This allows the user to be automatically returned to what he was trying to access.

Each value provides specific meanings. The concept of Security Interception is key to protecting resources under Acegi. Migrating to Microservice Databases.

Here is where the AuthenticationManager plays its role in the authentication chain. As I said in step 1, downloading Spring Security was the trickiest step of all.

Swcurity, the bean will utilize this to proceed through the authentication chain. It tells the interceptor to examine the remaining parameters using Apache Ant style pattern matching rather than the default pattern matching using regex.

As one would imagine, the first is thrown when an incorrect principal and credentials are provided. This method that takes a username and loads the respective user details to verify for authentication by Seurity Developers are free to create their own implementation, for example, using Hibernate; however, Acegi ships with two very usefully implementations, a JDBC-based and memory-based.


Please consult the reference documentation to learn more. Enterprise Implementation in Java. While developers are welcome to implement a custom Seurity when appropriate, most circumstances allow for use of the implementations that are based upon the concept of voting.

See our privacy notice for details. Furthermore, the entire framework serves as an excellent example of extensibility through abstraction. Furthermore, please provide feedback and requests as guidance for the next installment.

For this reason, Acegi provides two key interfaces for providing xcegi services — Authentication and AuthenticationManager.

The collision of these factors has the impact of making security forgetful, error prone, and potentially dangerous, especially for enterprise applications.

The second is a reference to the instantiated RoleVoter. For the most part, the filter handles session management and URL redirection for user login as specified by an AuthenticationEntryPoint object while delegating to the interceptor for security decisions.

Finally, the AffirmativeBased implementation grants access if at least one access granted is received while deny votes are sceurity. Let’s examine each of these to find out how they form a complete authentication system.
