Spring Boot AuthenticationManagerBean不工作

Question

在我的项目中，当我试图通过重写AuthenticationManagerBean（）方法为AuthenticationManager定义bean时，它显示了以下错误，

SecurityConfiguration类型的authenticationManagerBean（）方法必须重写或实现超类型方法

下面给出了我定义的方法，

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

我的整个安全配置类如下所示，

package com.toorjaridwan.introvertreadersauth.Configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.BeanIds;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

import com.toorjaridwan.introvertreadersauth.Service.UserDetailService;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration {

    @Autowired
    private UserDetailService userDetailService;

    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailService);
    }

    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests().antMatchers("/authenticate").permitAll()
        .anyRequest().authenticated();
    }

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

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

}

在之前使用Spring Boot 2.1.9版本的项目中，一切都很顺利，没有任何问题。现在我使用的是Spring Boot版本2.2.6。我不知道这是否是原因。

在寻找解决方案时，我遇到了这个和这个。我发现事情和我做的一样。

我正在运行64位Ubuntu 16.04 LTS和Java版本1.8

尝试添加

extends WebSecurityConfigurerAdapter
