如果你想继续 Boot 启动程序包，根据发行说明，你需要覆盖WebSecurityConfigurerAdapter中的authanticationManagerBean方法。

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

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

}

在 Boot 的最新版本中，类WebSecurityConfigurerAdapter已被弃用，您必须使用新的样式来编写安全配置，

我有一个JWT标记过滤器，需要插入它来验证传入的JWT标记。
