dependency for spring security

Add the Spring Security dependency to the Maven pom.xml file. This can be done by including the appropriate dependency coordinates within the section of the pom.xml.

Create a Spring Security configuration class that extends WebSecurityConfigurerAdapter. This class should override the configure(HttpSecurity http) method to define the security configurations for the application.

Use the @EnableWebSecurity annotation on the main application configuration class to enable Spring Security for the application.

Define user authentication and authorization details in the configure(AuthenticationManagerBuilder auth) method of the security configuration class. This involves specifying the user details service, password encoder, and any custom authentication providers.

Configure access control and security rules using the HttpSecurity object within the configure(HttpSecurity http) method of the security configuration class. This includes defining access rules based on URL patterns, enabling form login, logout behavior, and other security configurations.

Optionally, customize the login form, error handling, and other security-related features by extending the WebSecurityConfigurerAdapter and overriding additional methods as needed.

Test the security configurations by running the Spring application and verifying that the defined security rules and behaviors are applied as expected.

Continue to refine and adjust the security configurations based on the specific requirements of the application, considering factors such as role-based access control, custom authentication mechanisms, and security best practices.
