Spring Boot FAQ: Top Questions

Spring Boot integrates with Spring Security to provide comprehensive security for REST APIs using configurations and annotations.

🗺️ Steps:

1. Add spring-boot-starter-security.
2. Define a SecurityFilterChain or extend WebSecurityConfigurerAdapter.

📥 Example:

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
  http.csrf().disable()
      .authorizeHttpRequests()
      .requestMatchers("/api/public").permitAll()
      .anyRequest().authenticated()
      .and()
      .httpBasic();
  return http.build();
}

🏆 Expected Output:

/api/public is open, others require authentication.

🛠️ Use Cases:

• Role-based access control.
• JWT or basic auth integration.
