Spring Security筛选器链未忽略指定路径[重复]

Question

我有一个通过JWT进行身份验证的Spring Boot REST API。我的问题是，我已经将Spring Security配置为允许不受限制地访问用于对/auth/token进行身份验证的路径，但它仍然在不应该访问的情况下访问我的安全过滤器。我不知道我哪里错了任何忠告都是恰当的

public class JwtWebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private JwtAuthenticationEntryPoint unauthorizedHandler;

    @Autowired
    private UserDetailsService userDetailsService;

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

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

    @Bean
    public JwtAuthenticationFilter authenticationTokenFilter() throws Exception {
        return new JwtAuthenticationFilter();
    }

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity
            .authorizeRequests()
            .antMatchers("/auth/token").permitAll() // do not authenticate
            .anyRequest().authenticated()

            // TODO: configure
            .cors()
            .and()

            // TODO enable and configure
            .csrf().disable()

            // Unauthorized request handler
            .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()

            // Keep application security stateless
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

        // JWT security filter
        httpSecurity.addFilterBefore(authenticationTokenFilter(), 
            UsernamePasswordAuthenticationFilter.class);

        // Disable page caching to prevent cached REST responses
        httpSecurity.headers().cacheControl();
    }

    @Override
    public void configure(WebSecurity webSecurity) throws Exception {
        webSecurity.ignoring().antMatchers(HttpMethod.POST, "/auth/token");
    }
}

public class JwtAuthenticationFilter extends OncePerRequestFilter {
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
        FilterChain chain) throws ServletException, IOException {
        // this runs
    }
}

@RestController
public class AuthenticationController {

    // Authenticate user
    @RequestMapping(value = "/auth/token", method = RequestMethod.POST)
    public ResponseEntity<?> createAuthenticationToken(HttpServletResponse response,
        @RequestBody JwtAuthenticationRequest authenticationRequest, Device device) throws AuthenticationException {
        // never gets to run
    }
}

感谢@dur询问我是否在使用Spring Boot，让我找到了解决方案。

这让我开始思考Spring Boot喜欢自动地为我们创建bean，而这最终成了这里的罪魁祸首。结果显示，我的jWTauthenticationfilter类被Spring Boot自动放入筛选器链中，但当我在安全配置中显式声明它时，它也包含在安全筛选器链中。因此，尽管我在安全配置中的忽略()方法中排除/auth/token是正确的，但这不足以阻止筛选在Spring Boot本身的上下文中发生。解决方案是配置一个bean，显式地防止Spring Boot添加bean

@Bean
public RegistrationBean jwtAuthFilterRegister(JwtAuthenticationFilter filter) {
    FilterRegistrationBean registrationBean = new FilterRegistrationBean(filter);
    registrationBean.setEnabled(false);
    return registrationBean;
}
