Spring安全性没有显式映射/错误

Question

基本上当我去localhost：8080 /登录时，我得到以下404页面：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available

我在pom.xml中的依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>

我的安全配置：

protected void configure(HttpSecurity http) throws Exception {
    http

            .addFilterBefore(new CorsFilter(), SessionManagementFilter.class)
            .authorizeRequests()
            .antMatchers("/")
            .permitAll()
            .anyRequest().authenticated()
            .and()
            .formLogin()
            .loginPage("/login")
            .loginProcessingUrl("/login")
            .failureHandler(new CustomAuthenticationFailureHandler())
            .successHandler(new CustomAuthenticationSuccessHandler())
            .permitAll()
            .and()
            .logout()
            .permitAll()
            .and()
            .httpBasic()
            .and()
            .csrf().disable();

}

其他一切都很好。我检查了项目的结构，所有控制器都在应用程序位置的子包中。
