CustomAuthenticationProvider无法正常工作

Question

我正在使用SpringMVC和Spring安全性，并且我已经设置了CustomAuthenticationProvider。对我来说，说我只使用注释很重要，我没有spring-security.xml，我在每个教程中都说这个原因我看到他们使用它来设置身份验证管理器但是没有＆＃ 39;不适合我的项目。所以，我做的很简单，我创建了一个CustomAuthenticationProvider，如下所示：

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider{

@Autowired
private AccountRepository accountRepository;

@Autowired
private PasswordEncoder passwordEncoder;

private CustomAuthenticationProvider() {}

@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
    Account user = accountRepository.findOneByEmail(authentication.getName());
    if(user!=null){
        if(passwordEncoder.matches(authentication.getCredentials().toString(), user.getPassword())){
            List<GrantedAuthority> grantedAuths = new ArrayList<>();
            grantedAuths.add(new SimpleGrantedAuthority(user.getRole()));
            return new UsernamePasswordAuthenticationToken(authentication.getName(), authentication.getCredentials().toString(), grantedAuths);
        }else{
            throw new BadCredentialsException("Bad credentials for user " + authentication.getName());
        }
    }
    throw new UsernameNotFoundException("User not found for " + authentication.getName());
}

@Override
public boolean supports(Class<?> authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
}

}

此外，我已经修改了扩展WebSecurityConfigurerAdapter的SecurityConfig.java，我已经添加了 此外，我修改了configure方法来设置authProvider，正如大多数教程所说：

package ar.com.neex.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.web.authentication.rememberme.TokenBasedRememberMeServices;

import ar.com.neex.account.AccountService;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
@ComponentScan("ar.com.neex")
class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private CustomAuthenticationProvider authProvider;

    @Autowired
    private AccountService accountService;

    @Bean
    public TokenBasedRememberMeServices rememberMeServices() {
        return new TokenBasedRememberMeServices("remember-me-key", accountService);
    }

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

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .authenticationProvider(authProvider)
            .eraseCredentials(true)
            .userDetailsService(accountService)
            .passwordEncoder(passwordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/favicon.ico", "/resources/**", "/signup", "/about").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/signin")
                .permitAll()
                .failureUrl("/signin?error=1")
                .loginProcessingUrl("/authenticate")
                .and()
            .logout()
                .logoutUrl("/logout")
                .permitAll()
                .logoutSuccessUrl("/signin?logout")
                .and()
            .rememberMe()
                .rememberMeServices(rememberMeServices())
                .key("remember-me-key");
    }

    @Bean(name = "customAuthenticationProvider")
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

问题是，当我启动我的应用程序时遇到错误，它是以下内容：

我尝试添加spring-security.xml并在web.xml中添加过滤器，就像我在教程中看到的那样（尽管我认为我不需要），但是它已经不工作。

如果您有任何想法，我真的很感激。

谢谢你们！

将您的代码更改为此

@Component("cAuthenticationProvider")
public class CustomAuthenticationProvider implements AuthenticationProvider{
 ....
}


@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
@ComponentScan("ar.com.neex")
class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("cAuthenticationProvider")
    private AuthenticationProvider authProvider;

    ....
}
