springsecurity進行登陸認證時There is no PasswordEncoder mapped for the id “null“ 錯誤處理

問題描述

在使用springsecurity6.0版本進行登陸認證時，出現如下錯誤：

原因分析：

在springsecurity5.0之後引入了許多加密方式，是以在校驗是需要指定一種加密方式

在我的securityConfig中，authenticationProvider的代碼如下：

@Bean
    public AuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setUserDetailsService(userDetailsService);
        return daoAuthenticationProvider;
    }
           

是以在建構是需要添加加密方式

解決方案：

在建構的authenticationProvider中需要填加密碼加密方式：

代碼如下：

@Bean
    public AuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setUserDetailsService(userDetailsService);
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        return daoAuthenticationProvider;
    }
           

附上我的Springsecurityconfig全部代碼：

代碼如下：

package com.lp.framework.security.config;

import com.lp.framework.security.core.SpringSecurityUserDetailsServiceImpl;
import jakarta.annotation.Resource;
import lombok.RequiredArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.ProviderManager;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@EnableWebSecurity
public class SpringSecurityConfigurer{

    @Resource
    SpringSecurityUserDetailsServiceImpl userDetailsService;
  
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        //設定請求必須進行權限認證
        http.authorizeHttpRequests(authz ->{authz
                        .requestMatchers("/login").permitAll()// 放行登入接口
                        .anyRequest().authenticated();// 其餘的都需要權限校驗
                })
                .authenticationProvider(authenticationProvider())
                //關閉csrf防禦，相似于防火牆，不關閉上面的設定不會真正生效。// 防跨站請求僞造
                .csrf().disable();

        return http.build();
    }

    @Bean
//    密碼加密,不然沒法做密碼加密對比
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }


    /**
     * 擷取AuthenticationManager（認證管理器），登入時認證使用
     */
    @Bean
    public AuthenticationManager authenticationManager(AuthenticationConfiguration config) throws Exception {
//        return authenticationConfiguration.getAuthenticationManager();
//        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
//        daoAuthenticationProvider.setUserDetailsService(userDetailsService);
//        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        return config.getAuthenticationManager();
    }

    @Bean
    public AuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setUserDetailsService(userDetailsService);
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        return daoAuthenticationProvider;
    }
}
