java - 用户身份验证失败时出现 Spring Security ProviderNotFoundException

Question

我已经设置了一个类似于此处示例的 LDAP 自定义身份验证提供程序 - https://www.baeldung.com/spring-security-authentication-provider
有一个登录 Controller 来处理登录错误并检查用户是否在批准的列表中。 Controller 调用自定义身份验证提供程序 authenticationManager.authenticate()方法。
当提供错误的凭据时，自定义身份验证提供程序将被调用两次。抛出两个异常。
第一个异常(exception):

        at com.tools.web.JwtAuthenticationRestController.authenticate(JwtAuthenticationRestController.java:70) [classes!/:1.0.0-SNAPSHOT]

第二个异常(exception):

c.c.t.a.CustomAuthenticationProvider.authenticate - User does not have access
31-12-2020 15:42:55.613 [http-nio-9090-exec-6] ERROR c.c.t.w.JwtAuthenticationRestController.authenticate - Exception logging in user

        at com.tools.web.JwtAuthenticationRestController.authenticate(JwtAuthenticationRestController.java:70) [classes!/:1.0.0-SNAPSHOT]

这是自定义提供程序:

public class CustomAuthenticationProvider implements AuthenticationProvider {

    @Override
    public Authentication authenticate(Authentication authentication)
            throws AuthenticationException {
        String name = authentication.getName();
        String password = authentication.getCredentials().toString();

        if (hasAccess(name, password)) {
            Authentication auth = new UsernamePasswordAuthenticationToken(name,
                    password);
            return auth;
        } else {
            return null;
        }
    }

    public boolean supports(Class<?> authentication) {
        return true;
    }

    public boolean hasAccess(final String username, final String password) {
    //LDAP access happens here
    }
}

这是 Controller :

public class JwtAuthenticationRestController {

    @Autowired
    private AuthenticationManager authenticationManager;

    @CrossOrigin
    @RequestMapping(value = "/authenticate", method = RequestMethod.POST)
    public ResponseEntity<?> createAuthenticationToken(@RequestBody JwtTokenRequest authenticationRequest)
            throws AuthenticationException {
        authenticate(authenticationRequest.getUsername(), authenticationRequest.getPassword());
         //generate token
        return ResponseEntity.ok(new JwtTokenResponse(token));
    }

    @ExceptionHandler({AuthenticationException.class})
    public ResponseEntity<String> handleAuthenticationException(AuthenticationException e) {
    //handle exception. set custom response.
    }

    private void authenticate(String username, String password) {   
        try {
            // Check against the approved user list
            //Authenticate the user - Exception thrown here
            authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password));
        }catch (Exception e) {
            throw new AuthenticationException("APPLICATION_ERROR", e);
        }
    }
}

更新 这是网络安全配置:

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

    @Autowired
    private JwtUnAuthorizedResponseAuthenticationEntryPoint jwtUnAuthorizedResponseAuthenticationEntryPoint;

    @Autowired
    private JwtTokenAuthorizationOncePerRequestFilter jwtAuthenticationTokenFilter;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(new CustomAuthenticationProvider());
    }   

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

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity
            .csrf().disable()
            .exceptionHandling().authenticationEntryPoint(jwtUnAuthorizedResponseAuthenticationEntryPoint).and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
            .authorizeRequests()
            .anyRequest().authenticated();

        httpSecurity
                .addFilterBefore(jwtAuthenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);

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

    @Override
    public void configure(WebSecurity webSecurity)  {
        webSecurity
            .ignoring()
            .antMatchers(
                HttpMethod.POST,
                "/authenticate" //authentication path
            )
            .antMatchers(HttpMethod.OPTIONS, "/**")
            .and()
            .ignoring()
            .antMatchers(
                HttpMethod.GET,
                        "\"login" //Ignore security for Login page.
                )
            .and()
            .ignoring()
            .antMatchers("/h2-console/**/**");    
    }

仅当由于密码无效而导致身份验证失败时才会发生这种情况。我已经检查过自定义提供程序抛出 javax.naming.AuthenticationException并为 invalis 凭据返回 null。
为什么 Spring 会因身份验证失败而抛出此异常？解决方法是将 Controller 中的异常作为登录失败来处理，但是理解为什么会发生这种情况还是很好的。

Answer 1

您是否验证了 CustomAuthenticationProvider正在从您的 Controller 中调用？这个异常(exception)很明显来自 ProviderManager类(class)。来自 ProviderManager文档:

If no provider returns a non-null response, or indicates it can even process an Authentication, the ProviderManager will throw a ProviderNotFoundException.

如果您遵循了 Baeldung 示例，则 spring 在调用堆栈中比您的 Controller 处理身份验证过程的位置要远得多。
