我正在应用程序中实现Spring Security，但遇到了一个错误，我无法理解。
这个错误是由我在Security Config类中创建的"SecurityFilterChain" Bean引起的。
如果我删除@Bean注释，它就可以正常工作，但是api调用永远不会被内置的CustomAuthenticationFilter拦截处理身份验证。
以下是代码:
@Configuration
@EnableWebSecurity @RequiredArgsConstructor
public class SecurityConfig {
private final UserDetailsService userDetailsService;
private final BCryptPasswordEncoder passwordEncoder;
@Bean
public AuthenticationManager authenticationManager(HttpSecurity httpSecurity) throws Exception{
return httpSecurity.getSharedObject(AuthenticationManagerBuilder.class)
.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder)
.and()
.build();
}
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.csrf().disable();
http.httpBasic();
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http.authorizeHttpRequests().anyRequest().permitAll();
http.addFilter(new CustomAuthenticationFilter(authenticationManager(http)));
return http.build();
}
}
运行应用程序时的堆栈跟踪如下所示

@EnableWebSecurity将自动关闭默认的Web应用程序安全配置，供您参考。我建议您先尝试不使用它，但是，您能否展示一下您所有与Spring相关的依赖项（特别是安全方面的）？此外，您是否在代码中的任何地方使用了这个注释@EnableJpaRepositories？ - turbofood
