Atomic Updates on MongoDB with Spring Data

MongoDB provides operators for atomic updates in addition to the normal insert and modify functionality. These operators include, $inc, $set and $unset; and are particularly useful for keeping counters and for thread-safe field updates, which helps resolve data-related concurrency issues in web and multi-threaded applications. If persistence is required and performance is not an issue, these […]

CAS Integration Spring

CAS and distributed Infinispan integration

CAS is a centralised authentication server that makes it very easy to implement single sign-on (SSO) in java application, and is a very good OAuth alternative. For distributed/clustered environments CAS also offers integration with a number of caching technologies in order to support single-logout (SLO). Recently we had an issue on clustered Wildfly J2EE servers […]

Spring and Infinispan Integration on Wildfly Cluster

Spring framework provides a caching abstraction API that makes it very easy and consistent to use a lot of embeddable caching frameworks like, EHCache, Infinispan, Hazelcast etc. But sometimes it is also necessary to integrate with the underlying application server’s caching framework, especially in a clustered, distributed environment. In this post I will show how we can integrate […]

RegEx based Spring AOP auto-proxy creator

When using Spring AOP in a medium-large application to add behavior to objects using crosscutting, it is desirable to have auto-proxy creators rather then creating a proxy for each bean (Spring AOP is proxy based). When auto-proxying a subset of beans, BeanNameAutoProxyCreator is most commonly used. But it has certain limitations, you have to provide […]

Cas-Acegi-Spring integration on JBoss

CAS and Acegi are popular open source authentication and identity solutions available for enterprise java applications. CAS is a Centralized Authentication Server used for single sign-on and to decouple authentication mechanism from applications. Acegi is an authentication API used to put role-based access control on application. This is a simple example that shows how to […]
