spring boot security maven

To use Spring Boot Security with Maven, you need to follow these steps:

1. Add Spring Boot Security dependency to your Maven project by adding the following code to your pom.xml file:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

1. Create a custom security configuration class by creating a new Java class and annotating it with @Configuration and @EnableWebSecurity. This class will extend WebSecurityConfigurerAdapter and override its methods to customize the security settings. For example:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/public").permitAll()
            .anyRequest().authenticated()
            .and()
            .formLogin()
            .and()
            .logout().permitAll();
    }
}

1. (Optional) If you want to use in-memory user authentication, you can override the configure(AuthenticationManagerBuilder) method in your security configuration class. For example:

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication()
        .withUser("user")
        .password("{noop}password") // {noop} is used to indicate plain text password
        .roles("USER");
}

1. (Optional) If you want to use a custom user details service or provide a custom authentication provider, you can implement the UserDetailsService or AuthenticationProvider interfaces respectively and wire them into your security configuration class.

2. Run your application and test the security settings. By default, Spring Boot Security will provide a login form at the "/login" URL and use HTTP Basic authentication for API endpoints.

That's it! You have successfully integrated Spring Boot Security with Maven in your project. You can now customize the security settings based on your application's requirements.
