无法在Spring Boot中初始化Bean

Question

I am trying to create a bean in spring boot configuration class. But I am getting error when I run the application.

My Configuration class is

@Configuration
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {

@Autowired
private UserDetailsService userDetailsService;

@Autowired
private BCryptPasswordEncoder bCryptPasswordEncoder;

public WebSecurity( UserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder )
{
    this.userDetailsService = userDetailsService;
    this.bCryptPasswordEncoder = bCryptPasswordEncoder;
}

@Bean
public JWTAuthenticationFilter jwtAuthenticationFilter() throws Exception
{
    return new JWTAuthenticationFilter(authenticationManager());
}

@Bean
public JWTAuthorizationFilter jwtAuthorizationFilter() throws Exception
{
    return new JWTAuthorizationFilter(authenticationManager());
}

@Override
protected void configure( HttpSecurity http ) throws Exception
{
    http.cors().and().csrf().disable().authorizeRequests().antMatchers(HttpMethod.POST, "/rest/auth/**").permitAll()
            .antMatchers("/static/*").permitAll().antMatchers("/").permitAll()
            /* .anyRequest().authenticated() */.and().logout()
            .logoutRequestMatcher(new AntPathRequestMatcher("/logout")).clearAuthentication(true)
            .logoutSuccessUrl("/").and().addFilter(jwtAuthenticationFilter())
            .addFilter(jwtAuthorizationFilter());
}

@Override
public void configure( AuthenticationManagerBuilder auth ) throws Exception
{
    auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}

@Override
public void configure( org.springframework.security.config.annotation.web.builders.WebSecurity web )
        throws Exception
{

    web.ignoring().antMatchers("/static/**");
}

@Bean
CorsConfigurationSource corsConfigurationSource()
{
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
    return source;
}
}

The two @Bean classes I am trying to use in @Override protected void configure( HttpSecurity http ) throws Exception method. But is throwing the above mentioned error. How to resolve this?

我建议您添加这样的内容
@Override @Autowired public void setAuthenticationManager(AuthenticationManager authenticationManager) { super.setAuthenticationManager(authenticationManager); }
