Error creating bean with name 'springSecurityFilterChain'

if you are using **spring boot 3** must be considered that In **Spring Security 5.7.0-M2 the WebSecurityConfigurerAdapter is deprecated**. so you must Upgrade the Deprecated WebSecurityConfigurerAdapter with the correct beans.

Below is an example configuration using the **WebSecurityConfigurerAdapter** that secures all endpoints with HTTP Basic:

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests((authz) -> authz
.anyRequest().authenticated()
)
.httpBasic(withDefaults());
}

}

Going forward, the recommended way of doing this is registering a **SecurityFilterChain** bean:

@Configuration
public class SecurityConfiguration {

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests((authz) -> authz
.anyRequest().authenticated()
)
.httpBasic(withDefaults());
return http.build();
}

}

I had the same error message and the problem was that I had 2 RequestMappings defined with the same path, and honestly the error message is the least specific thing ever, maybe someone reading this review is running with the same issue right now, so please check that! :)
