Mastering Spring MVC 4

Overview of this book

<p>Spring MVC is the ideal tool to build modern web applications on the server side. With the arrival of Spring Boot, developers can really focus on the code and deliver great value, leveraging the rich Spring ecosystem with minimal configuration.</p> <p>Spring makes it simple to create RESTful applications, interact with social services, communicate with modern databases, secure your system, and make your code modular and easy to test. It is also easy to deploy the result on different cloud providers.</p> <p>Mastering Spring MVC will take you on a journey from developing your own web application to uploading it on the cloud.</p> <p>You begin by generating your own Spring project using Spring Tool suite and Spring Boot.</p> <p>As you develop an advanced-level interactive application that can handle file uploads as well as complex URLs, you will dive into the inner workings of Spring MVC and the principles of modern web architectures.</p> <p>You will then test, secure, and optimize your Spring web application and design RESTful services that will be consumed on the frontend.</p> <p>Finally, when everything is ready, you will release your application on a cloud provider and invite everyone to see.</p>

The login form


Basic authentication is good for our RESTful API, but we would rather have a login page carefully designed by our team to improve the web experience.

Spring Security allows us to define as many WebSecurityConfigurerAdapter classes as we need. We will split our SecurityConfiguration class into two parts:

  • ApiSecurityConfiguration: This will be configured first. This will secure the RESTful endpoints with basic authentication.

  • WebSecurityConfiguration: This will then configure login form for the rest of our application.

You can remove or rename SecurityConfiguration and create ApiSecurityConfiguration instead:

@Configuration
@Order(1)
public class ApiSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    public void configureAuth(AuthenticationManagerBuilder auth)
        throws Exception {
        auth.inMemoryAuthentication()
            .withUser("user").password("user").roles("USER").and()
            .withUser("admin").password("admin").roles("USER...
