Java Spring 2.19使用自定义身份验证登录失败

我遵循一个教程，当我尝试使用foo作为用户名和密码登录时，我得到了无效的用户名和密码。实际上，我不认为需要输入foo值，但我遵循教程

package com.dac.imoveis.controllers;

import com.dac.imoveis.controllers.MyUserDetailsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;   


@EnableWebSecurity
public class SecurityConfigurer extends WebSecurityConfigurerAdapter {

    @Autowired
    private MyUserDetailsService myUserDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
         auth.userDetailsService(myUserDetailsService);
    }

     @Bean
    public PasswordEncoder passwordEncoder(){
    return NoOpPasswordEncoder.getInstance();
    }

}

用户详细信息服务

 package com.dac.imoveis.controllers;

import java.util.ArrayList;
import org.springframework.context.annotation.Bean;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;

@Service
class MyUserDetailsService implements UserDetailsService {

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        return new User("foo", "foo", new ArrayList<>());
    }



}

我正在学习一个教程，那是哪个教程？因为我非常确定您的SecurityConfigure类缺少@Configuration注释，没有它，Spring框架将忽略该类。如果您正在使用的教程也缺少注释，那么您应该停止使用有缺陷的教程。否则，如果您遵循某个教程，请确保正确地遵循该教程。本教程我添加了@Configuration，但结果相同。由于我们看不到您的其余代码，我们只能想知道您还犯了什么错误，使其无法工作。我将添加更多代码。

     @SpringBootApplication
@ComponentScan(basePackages={"com.dac.imoveis.controllers"})
public class ImoveisApplication {

    public static void main(String[] args) {
        SpringApplication.run(ImoveisApplication.class, args);
    }

}
