Overview of this book

Knowing that experienced hackers are itching to test your skills makes security one of the most difficult and high-pressured concerns of creating an application. The complexity of properly securing an application is compounded when you must also integrate this factor with existing code, new technologies, and other frameworks. Use this book to easily secure your Java application with the tried and trusted Spring Security framework, a powerful and highly customizable authentication and access-control framework. The book starts by integrating a variety of authentication mechanisms. It then demonstrates how to properly restrict access to your application. It also covers tips on integrating with some of the more popular web frameworks. An example of how Spring Security defends against session fixation, moves into concurrency control, and how you can utilize session management for administrative functions is also included. It concludes with advanced security scenarios for RESTful webservices and microservices, detailing the issues surrounding stateless authentication, and demonstrates a concise, step-by-step approach to solving those issues. And, by the end of the book, readers can rest assured that integrating version 4.2 of Spring Security will be a seamless endeavor from start to finish.

The UserDetailsManager interface

We have already leveraged the InMemoryUserDetailsManager class in Spring Security in Chapter 3, Custom Authentication, to look up the current CalendarUser application in our SpringSecurityUserContext implementation of UserContext. This allowed us to determine which CalendarUser should be used when looking up the events for the My Events page. Chapter 3, Custom Authentication, also demonstrated how to update the DefaultCalendarService.java file to utilize InMemoryUserDetailsManager, to ensure that we created a new Spring Security user when we created CalendarUser. This chapter reuses exactly the same code. The only difference is that the UserDetailsManager implementation is backed by the JdbcUserDetailsManager class of Spring Security, which uses a database instead of an in-memory datastore.

What other features does UserDetailsManager provide out...
