Spring Security 3.x Cookbook

Chapter 2. Spring Security with Struts 2

In this chapter we will cover:

  • Integrating Struts 2 with Spring Security
  • Struts 2 application with basic Spring Security
  • Using Struts 2 with digest/hashing-based Spring Security
  • Using Spring Security logout with Struts 2
  • Authenticating databases with Struts 2 and Spring Security
  • Getting the logged-in user info in Struts 2 with Spring Security
  • Displaying custom error messages in Struts 2 for authentication failure
  • Authenticating with ApacheDS with Spring Security and Struts 2 application

Introduction

We learned the basics of security in Chapter 1, Basic Security, which helped us to understand Spring Security better and also the origin of the Spring Security component in the Spring Framework.

In this chapter, let's see how Spring Security can be used to authenticate users in a Struts 2 framework-based web application.

Apache Struts 2 can be integrated with JSF and Spring. It is a very flexible POJO Action-based MVC framework. POJO itself performs the role of an action class to fulfill the requests. Struts 2 is derived from another framework called WebWork and it works with servlet filters, which intercept the request and response.

Exploring the Spring package

You can download the JARs from MAVEN directly or add the dependency in your POM file.

We prefer to use the latest JARs 3.1.4 from http://mvnrepository.com/artifact/org.springframework.security/spring-security-core/:

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId...

Integrating Struts 2 with Spring Security

Let's first set up a Struts 2 application and integrate Spring Security with it.

Getting ready

  • Eclipse Indigo or higher version
  • JBoss as server
  • Struts 2 JARs: 2.1.x
  • Spring-core JARs 3.1.4. Release and Spring-Security 3.1.4.Release
  • Struts 2 Spring plugin jar

How to do it...

In this section, we will learn how to set up the Struts 2 application with form-based Spring Security:

  1. In your Eclipse IDE, create a dynamic web project and name it Spring_Security_Struts2.
  2. Create a source folder at src/main/java.
  3. Create a struts.xml file under the source folder src/main/java.
  4. To integrate Struts 2 with the Spring application, add the application-context.xml file reference here.
  5. Add the Struts filter mapping in web.xml. Spring listener also needs to be added to the web.xml file. The listener entry should be above the Struts 2 filter entry.
  6. The contextLoaderListener will tell the servletcontainer about the springcontextLoader and it will track events. This also allows the...

Struts 2 application with basic Spring Security

In this section we will demonstrate basic Spring Security authentication with Struts 2. We will create a sample Struts 2 application and add Spring Security features to the action to make it secured. Only authenticated authorized users can access it.

Getting ready

  • Update the Applicationcontext-security.xml file
  • Create a new dynamic project in Eclipse: Struts2_Spring_BASIC_Security_Recipe2

How to do it...

Perform the following steps for integrating the Struts 2 application with Spring Security to implement basic authentication:

  1. Modify the applicationcontext-security.xml file to support basic security:

    Applicationcontext-security.xml:

    <beans:beans xmlns="http://www.springframework.org/schema/security"
       xmlns:beans="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework...

Using Struts 2 with digest/hashing-based Spring Security

Using the form-based or basic authentication doesn't make the Struts 2-based application secure since the passwords are exposed to the user as plain text. There is a crypto package available in Spring Security JAR. The package can decrypt the encrypted password, but we need to tell the Spring Security API about the algorithm used for encryption.

Getting ready

  • Create a dynamic web project in Eclipse
  • Add the Struts 2 JARs
  • Add Spring Security related JARs
  • The web.xml, struts2.xml, and JSP settings remain the same as the previous application

How to do it...

Let's encrypt the password: packt123456.

We need to use an external JAR, JACKSUM, which means Java checksum. It supports both MD5 and SHA1 encryption.

Download the jacksum.zip file (http://www.jonelo.de/java/jacksum/#Download) and extract the ZIP folder.

packt>java -jar jacksum.jar -a sha -q"txt:packt123456"
How to do it...

Update the applicationcontext-security.xml file:

<beans:beans...

Using Spring Security logout with Struts 2

In this section let us implement a logout scenario, where the logged-in user will be logged out of the application. The logout action will be handled by the Spring Security framework. We need to configure the struts.xml file to handle the j_spring_security_logout action.

Getting ready

  • Create a dynamic web project in Eclipse
  • Add the Struts 2 related JARs
  • Add Spring Security-related JARs
  • The web.xml, struts2.xml, and JSP settings remain the same as the previous application

How to do it...

  1. Let's update the secure page, hello.jsp:
    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
    <%@page import="java.security.Principal" %>
    <html>
    <body>
    Hello .You are seeing a secured Page now.
       
       <a href="<c:url value="/j_spring_security_logout" />" > Logout</a>
     </body>
    </html>
  2. Let's map the j_spring_security_logout with the struts.xml file:

    When...

Authenticating databases with Struts 2 and Spring Security

In this section, let us authorize the user who logs into the Struts 2 application using the information stored in the database. Spring Security needs to be configured in Struts 2 application such that it gets to know the location of the database and SQL that needs to be executed to authenticate the user using Spring Security.

Getting ready

  • Create a dynamic web project in Eclipse: Struts2_Spring_DBAuthentication_Recipe4
  • Copy the struts.xml file to src/main/java
  • Add the db-beans.xml file to WEB-INF
  • Copy the webContent folder from the previous recipe
  • Add the following JARs into the lib folder or update your POM file if you are using maven:
    • spring-jdbc-3.0.7.RELEASE
    • mysql-connector-java-5.1.17
    • commons-dbcp
    • commons-pool-1.5.4

How to do it...

  1. To perform database authentication with Struts 2 and Spring, we need to create a db-beans.xml file. The db-beans.xml file will have database information:
    <beans xmlns="http://www.springframework.org/schema...

Key benefits

  • Learn about all the mandatory security measures for modern day applications using Spring Security
  • Investigate different approaches to application level authentication and authorization
  • Master how to mount security on applications used by developers and organizations

Description

Web applications are exposed to a variety of threats and vulnerabilities at the authentication, authorization, service, and domain object levels. Spring Security can help secure these applications against those threats. Spring Security is a popular application security solution for Java applications. It is widely used to secure standalone web applications, portlets, and increasingly REST applications. It is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications and it is currently used to secure numerous demanding environments including government agencies, military applications, and central banks. "Spring Security 3.x Cookbook" is a repository of recipes to help you successfully secure web applications against threats and vulnerabilities at the authentication and session level layers using the Spring Security framework. We will not only explore Spring-based web applications, but also Java-based and Grails-based applications that can use Spring Security as their security framework. Apart from conventional web applications, we will also look at securing portlets, RESTful web service applications, and other non-web applications. This book will also take you through how to integrate Spring Security with other popular web frameworks/technologies such as Vaadin, EJB, and GWT. In addition to testing and debugging the implemented security measures, this book will also delve into finer aspects of Spring Security implementation such as how it deals with concurrency, multitenancy, and customization, and we will even show you how to disable it. This book gives you an overview of Spring Security and its implementation with various frameworks. It starts with container-based authentication before taking you on a tour of the main features of Spring Security. It demonstrates security concepts like BASIC, FORM, and DIGEST authentication and shows you how to integrate the Spring Security framework with various frameworks like JSF, struts2, Vaadin, and more. The book also demonstrates how to utilize container managed security without JAAS. Then, we move on to setting up a struts2 application before showing you how to integrate Spring Security with other frameworks like JSF, Groovy, Wicket, GWT, and Vaadin respectively. This book will serve as a highly practical guide and will give you confidence when it comes to applying security to your applications. It's packed with simple examples which show off each concept of Spring Security and which help you learn how it can be integrated with various frameworks.

Who is this book for?

This book is for all Spring-based application developers as well as Java web developers who wish to implement robust security mechanisms into web application development using Spring Security. Readers are assumed to have a working knowledge of Java web application development, a basic understanding of the Spring framework, and some knowledge of the fundamentals of the Spring Security framework architecture. Working knowledge of other web frameworks such as Grails and so on would be an added advantage to exploit the whole breadth of recipes provided in this book, but this is not mandatory.

What you will learn

  • Implement Form-based, HTTP Basic, Client, and Digest authentications
  • Bring in Groovy on Grails with Form-based Spring Security
  • Integrate Spring Security with Vaadin
  • Combine Spring Security with ORM and NoSQLDB
  • Use Spring Security in Spring-Social (Facebook and Twitter)
  • Learn about Spring Security for SOAP
  • Authenticate RESTful services with Spring Security

I received Spring Security 3.x Cookbook as an eBook from Packt Publishing about a month ago. This was fortunate as I had prior to this point been struggling implementing Spring Security into our new Spring MVC sample developer’s web application at work (ultimately to become our standard Maven Archetype for new web development).The requirements at work insisted on Spring Security seamlessly meshing with our campus Shibboleth 2 Single Sign-On process. This is a bit like logging in without signing in – and not one of the core principles of Spring Security out of the box (generally concerned with classic Authentication via web form submission). It was therefore useful to see the information on Multiple Authentication in Chapter 11 (as I built a JPA example similar to Chapter 11 in this book).This book (as cookbook code format) immediately helped with understanding code syntax, formatting, location and common usage. Packt commonly uses headings like (Getting Ready, How to Do It, How It Works, There’s more and See Also) – but admittingly I was searching for code fragments that were similar to my needs – so it was the code (the How to Do It paragraphs) that I appreciated/needed the most.Also of note, many Maven related examples in the book and downloaded sample applications. Of note in the downloaded source (which may easily be the most valuable resource of this book, as the author produced an incredible amount of great code): * Useful examples of Maven POM dependency configurations * Nice to see hibernate configuration examples with classic persistence.xml settings (in contrast to Springs Pet Clinics XML based persistence layer API). * DAO objects, Glassfish JDBC configuration examples. * Nice interface and implementation services. * Example MVC controllers using Spring Security (very useful to see worked out examples). Again, largely XML based configuration versus annotation based. At the day job, we use a ton of annotation spring security objects as we needed a lot of overriding of core spring security API.Although some amount of examples utilize JDBC wired up with GlassFish (Chapter 7, 8, 9 and 11), and the commercial support for GlassFish has been halted by Oracle, the community version is still very active and working through these examples are largely unaffected by this issue.Chapter 1 of the Spring Security Cookbook dives into the topic of security with Java Authentication and Authorization Service (JAAS) - which I hadn't any experience with (typically using a framework of one type of another over the years to obtain these common services). The point I want to make here was this chapter didn't help me with the Spring Integration issues I has having – but did introduce me to some related and legacy core java services – and it was interesting reading. Having not known about these services to begin with, I admit I was a bit lost immediately and had me wondering what up, so to speak. Very interesting code in Chapter 11 examines implementing JAAS with Spring Security.Also, in review of many of the following chapters, (Spring Security with Struts, JSF, Grails, GWT, Vaadin, Wicket) I wanted to note that my development was classic JSP, Web 3.0 servlets and Spring MVC Core services through a standard Maven Eclipse project.Fortunately, the code fragments in the book of each of these frameworks required similar solutions to some of the problems I was having (and many were MVC based anyway) – and were useful. Even if the frameworks being discussed were not of particularly of interest to me (for my current job).Chapter 10 – Spring Security with Spring Web Services is a technology that I will be searching for solutions in about 2 months – as we begin to implement our ESB, as securing our Web services will be a hot topic for some time (very useful to see the cxf-servlet.xml example and generated Apache CXF WSDL here).To summarize, as there are a ton of issues I could write about (Java based configuration versus XML based configuration – both in the Spring MVC and Spring Security worlds for example), I wanted to close with an acknowledgment and recognition of the tremendous amount of work it took to build out all of the samples and code in Spring Security 3.x Cookbook – just wanted to say nice work!

This book has an interesting approach to the cookbook theme - most recipes describe integrating the Spring Security framework with a specific web framework. If you're just starting out with Spring Security, or applying it to a new framework, this book will save you a lot of time - well worth the book's price. These include Struts 2, JSF, Grails, GWT, Vaadin, Wicket and web services (REST and SOAP).There are also recipes on using it with Hibernate, MongoDB, JAAS, Captcha, multiple authentication providers, LDAP and Spring Social (OAuth, Facebook, Twitter). It doesn't go into extending Spring to do things like locking users out or counting invalid authentication attempts, etc. but covers basic authentication and authorization in the various use cases. There's probably room for another cookbook on extension recipes.I found this very useful for the Spring Social recipes, but if you're securing a new project this could save you days of work.

Yep, it's OK. I bought it mainly for the Grails info. Basic and a bit thin. It should have twice as much material and be twice as expensive.Really we need a book with a good solid grounding in Spring Security Core and UI for Grails. This isn't quite it.
