[FIXED] What is the alternative to the authenticationManagerBean function after the WebSecurityConfigurerAdapter class has been deprecated?

Issue

In Spring Boot 2.7.4, the WebSecurityConfigurerAdapterclass which contains the authenticationManagerBean function is deprecated

What is the alternative?

Solution

I found that the alternative is the getAuthenticationManager function in the AuthenticationConfiguration class

    @Bean
    protected SecurityFilterChain configure(final HttpSecurity http,
                                            final AuthenticationManagerBuilder auth,
                                            final AuthenticationConfiguration authenticationConfiguration) throws Exception {
        // set the authentication provider
        auth.authenticationProvider(daoAuthenticationProvider());

        // set the authorization and authentication rules
        return http
                .csrf().disable()
                // Make sure that the session is stateless because we are using JWT
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                // Add the JWT filter (my custom filter)
                .addFilter(new JwtFilter(authenticationConfiguration.getAuthenticationManager()))
                .build();
}
