I'm trying to build auth system with Spring Boot Security.
So I have custom auth provider (without @Component annotation)

public class CustomAuthProvider extends DaoAuthenticationProvider {



    @Override

    public Authentication authenticate(Authentication authentication)

            throws AuthenticationException {



        String name = authentication.getName();

        String password = authentication.getCredentials().toString();



        if (authentication.isAuthenticated()) {

            return authentication;

        }



        if ("user".equals(name) && "password".equals(password)) {



            return new UsernamePasswordAuthenticationToken(

                    name, password, new ArrayList<GrantedAuthority>(Arrays.asList(new SimpleGrantedAuthority("ROLE_USER"))));

        } else {

            return null;

        }

    }



    @Override

    public boolean supports(Class<?> authentication) {

        return (UsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication));

    }

}

which declared as a bean

@Bean

    public DaoAuthenticationProvider authProvider() {

        final CustomAuthProvider authProvider = new CustomAuthProvider();

        authProvider.setUserDetailsService(userDetailsService);

        return authProvider;

    }

Here is configuration:

@Override

    protected void configure(

            AuthenticationManagerBuilder auth) throws Exception {



        auth.authenticationProvider(authProvider());

    }



    @Override

    protected void configure(HttpSecurity http) throws Exception {

        http

                .csrf().disable()

                .authorizeRequests()

                .antMatchers("/admin/**").hasRole("ADMIN")

                .antMatchers("/anonymous*").anonymous()

                .antMatchers("/login*").permitAll()

                .antMatchers("/user/registration*").permitAll()

                .anyRequest().authenticated()

                .and().formLogin()

                .loginProcessingUrl("/login");

    }

When I'm trying post query to localhost:8080/login I'm getting sign-in form with message

No AuthenticationProvider found for
org.springframework.security.authentication.UsernamePasswordAuthenticationToken

spring's default request parameters for authentication are: username and password
you are sending email instead of username so it throws an exception somewhere in your authentication manager.

if you want to override the default values you can simply specify that in your HTTP security configs:

.formLogin()

    .loginProcessingUrl("/login") 

    .usernameParameter("email")

    .passwordParameter("password")
