customAuthenticationProvider 身份验证调用了两次

Question

我已经对此进行了研究，我认为作为评论（实际上在此线程中的答案下方：ProviderManager.authenticate called twice for BadCredentialsException）将是我的解决方案......但我仍然收到双重提交/调用以进行身份​​验证。第二个每次都有一个空密码。第一个调用有凭据。

下面是Java Config类和CustomAuthProvider类..

@Configuration
@EnableWebSecurity
public class UserWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter { 
@Override
protected void configure(HttpSecurity http) throws Exception {
    //@formatter:off
    http.antMatcher("/**")
            .authorizeRequests()
            .antMatchers("/", "/home**", "/login**","/create_user")
            .permitAll().anyRequest().authenticated()
        .and()
            .formLogin()
            .loginPage("/login")
            .loginProcessingUrl("/login")
            .failureUrl("/login?error")
        .and()
            .logout()
            .logoutSuccessUrl("/login?logout")
            .permitAll()
        .and()
            .exceptionHandling().accessDeniedPage("/login?denied") //in this simple case usually due to a InvalidCsrfTokenException after session timeout
        .and()
            .csrf()
                .ignoringAntMatchers("/rest/**")
        .and()
            .sessionManagement().enableSessionUrlRewriting(false)
        .and()
            .headers().frameOptions().deny();
}

... 然后是 customAuthProvider ...

@Component
public class CustomAuthProvider implements AuthenticationProvider {

@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
    if (authentication.getName() == null) {
        logger.warn("empty userName");
        return null;
    }

    if (authentication.getCredentials() == null) {
        logger.warn("empty password");
        return null;
    }

// code to check credentials etc ...

 if (!(user != null && userHash.equals(storedHash))) {
        System.out.println("fail");
        return  null;
    }

    return new UsernamePasswordAuthenticationToken(user,password);

}

Answer 1

修改了身份验证提供程序代码以以空授权列表结尾并返回 authenticationToken ...现在它可以工作了。

// ...        
UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(user,password, new ArrayList<>());
return authenticationToken;
