To integrate Spring Security for authentication interception in a Spring Boot project, you can follow these steps:

  1. Add a Spring Security dependency: include the Spring Security dependency in the pom.xml file.

  2. org.springframework.boot
    spring-boot-starter-security
  3. Create a Spring Security configuration class: Create a configuration class that extends WebSecurityConfigurerAdapter to configure Spring Security.
  4. This Java code declares a class named SecurityConfig which extends WebSecurityConfigurerAdapter and is annotated with @Configuration and @EnableWebSecurity.
  5. Configure authentication and authorization rules: Override the configure() method in the configuration class to set up authentication and authorization rules.
  6. Override the configure method of HttpSecurity to customize security settings. Permit access to URLs starting with “/public” for all users, while requiring authentication for all other requests. Customize the login page to “/login” and allow all users to logout.
  7. Create a login page: Set up a login page, such as login.html.
  8. Configure user information and password encryption: override the configure() method in the configuration class to set up encryption for user information and passwords.
  9. Here is an example of configuring authentication in-memory in a Spring application using the BCryptPasswordEncoder for password encryption. It creates a user with the username “admin” and password “admin123” with the role “ADMIN”.
  10. Ignore static resources in configuration: Override the configure() method in the configuration class to configure the access restrictions for static resources.
  11. import the WebSecurity configuration from the org.springframework.security.config.annotation.web package.

    Override the configure method to specify which resources WebSecurity should ignore, such as CSS, JS, and images directories.

  12. Run the project and test it: Start the Spring Boot project and access the authenticated resources. The system will redirect you to the login page, where you can enter your username and password to complete the authentication.

This completes the configuration of integrating Spring Boot with Spring Security to implement authentication interception. You can customize and extend as needed.
