spring - 为什么 AuthenticationManager 会抛出 StackOverflowError？

Question

我在调用 authenticationManger.authenticate() 时收到 StackOverflowError

java.lang.StackOverflowError: null at org.apache.commons.logging.LogAdapter$Slf4jLog.isDebugEnabled(LogAdapter.java:300) ~[spring-jcl-5.1.10.RELEASE.jar:5.1.10.RELEASE] at org.springframework.security.authentication.ProviderManager.authenticate(ProviderManager.java:162) ~[spring-security-core-5.1.6.RELEASE.jar:5.1.6.RELEASE] at org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter$AuthenticationManagerDelegator.authenticate(WebSecurityConfigurerAdapter.java:503) ~[spring-security-config-5.1.6.RELEASE.jar:5.1.6.RELEASE]

我正在尝试在我的应用程序中实现 JWT。我已经创建了 JWTTOkenUtil、过滤器和 Controller 。但只有身份验证管理器不工作。我也尝试过 CustomAuthenticationManger 但同样的错误。

文件 AppConfig.java

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

    @Autowired
    private JwtUserDetailService jwtUserDetailService;

    @Autowired
    private JwtAuthenticationProvider jwtAuthenticationProvider;

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

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(jwtAuthenticationProvider);

     //auth.userDetailsService(jwtUserDetailService).passwordEncoder(passwordEncoder());
    }

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
            .authorizeRequests().antMatchers("/version").permitAll()
            .anyRequest().authenticated()
            .and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        http.addFilterBefore(jwtRequestFilter(), UsernamePasswordAuthenticationFilter.class);
    }

    @Bean
    public JwtRequestFilter jwtRequestFilter() {
            return new JwtRequestFilter();
    }
}

WebSecurityConfigurerAdapter 的

authenticationManager() 和 authenticationManagerBean() 是两种不同的方法，您正在调用父类(super class)的 authenticationManagerBean() 方法，据我所知，这取决于 authenticationManager() 方法。这反过来会创建方法的循环调用，最终导致 StackOverflowError 异常。

您可以尝试不覆盖 AuthenticationManager authenticationManager() 方法，或者在这样做时返回可靠的实现。
