    }


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

}

注意:不要使用下面的方式会出现警告

  @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers(
                "/login",
                "index.html",
                "favicon.ico",
                "/doc.html",
                "/webjars/**",
                "/swagger-resources/**",
                "/v2/api-docs/**",
                "/captcha"
        );
    }

另外说一下SpringBoot2.6.5之后使用swagger3.0要进行配置

spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher
