Customizing and Extending Spring Security
Spring Security is a very extendable and customizable framework. This is primarily because the framework is built using object-oriented principles and design practices so that it is open for extension and closed for modification. In the previous chapter, you saw one of the major extension points in Spring Security—namely, the pluggability of different authentication providers. This chapter covers some other extension points in the framework that you can take advantage of to extend Spring Security’s functionality or to modify or customize functionality that doesn’t work exactly the way you need in your applications.
