Here are the main classes, all the requirements looks ok to me, I am using the org.springframework.boot release 1.5.7.RELEASE

package webroot.websrv.auth.config;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private JwtAuthenticationEntryPoint unauthorizedHandler;

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    public void configureAuthentication(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
        authenticationManagerBuilder
                .userDetailsService(userDetailsService)
                .passwordEncoder(passwordEncoder());
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public JwtAuthenticationTokenFilter authenticationTokenFilterBean() throws Exception {
        return new JwtAuthenticationTokenFilter();
    }

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity
                .csrf().disable()

                .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                .authorizeRequests()
                .antMatchers(
                        HttpMethod.GET,
                        "/",
                        "/**/*.html",
                        "/**/*.{png,jpg,jpeg,svg.ico}",
                        "/**/*.css",
                        "/**/*.js"
                ).permitAll()
                .antMatchers("/api/auth/**").permitAll()
                .anyRequest().authenticated();

        httpSecurity
                .addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);

        httpSecurity.headers().cacheControl();
    }
}

and:

package webroot.websrv;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class WebcliApplication {

    public static void main(String[] args) {
        SpringApplication.run(WebcliApplication.class, args);
    }
} 

Using Maven or Gradle it returns the same issue. All annotations and packages names seems to be as required.

Answer 1

Add a bean for UserDetailsService

@Autowired
private UserDetailsService userDetailsService;

@Bean
public UserDetailsService userDetailsService() {
    return super.userDetailsService();
}

Answer 2

I also come accross this error. In my case, I have a class JwtUserDetailsService and I have forget implement UserDetailsService. After adding implements UserDetailsService the error was disappered.

Note that: if you also have own UserDetailsService and you use Munna's answer, than you got error StackoverflowError it mean you also repited my mistake.

Answer 3

In Service class make annotation

@Service

to

@Service("userDetailsService")

Answer 4

Add @Autowired and @Bean Annotations for UserDetailsService in SecurityConfig class

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public UserDetailsService userDetailsService() {
        return super.userDetailsService();
    }
}

and

To allow circular references in application.properties

spring.main.allow-circular-references:true

Answer 5

I also got the same error. I fixed it by creating a bean that returns UserDetailsService.

@Configuration
@RequiredArgsConstructor
public class ApplicationConfig {

    @Bean
    public UserDetailsService userDetailsService() {
        return username -> userRepository.findByEmail(username).orElseThrow(() -> new UsernameNotFoundException(username));
    }
}
