getsUsername未调用自定义UsernamePasswordAuthenticationFilter Java配置

Question

编辑：方法getsUsername未被调用。代码进入

 doFilter(ServletRequest req, ServletResponse res,
            FilterChain chain)

但不在

protected String obtainUsername(HttpServletRequest request)

我在websecurity配置中添加了一个自定义UsernamePasswordAuthenticationFilter，但它不会在调试模式下进入方法方法obtainUsername（所以我猜它没有到达）

WebSecurityConfig
        http
            .csrf().disable() //TODO Refactor login form
            .addFilter(**customAuthenticationFilter**)
            .authorizeRequests()
                .antMatchers("/static/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .logout()
                .logoutSuccessUrl("/logout/success")
                .logoutUrl("/logout")
                .permitAll()
                .and()
            .formLogin()
                .defaultSuccessUrl("/welcome")
                .loginPage("/login")
                .failureUrl("/login/failure")
                .permitAll();

在我得到的日志中：
