Error: Required a bean of type 'org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder' that could not be found

Question

我想通过创建一个简单的登录屏幕在我的项目中使用 Spring Boot Security，但是我在运行 y application

时收到这些错误

说明： com.panchmeru_studio.controller.UserController 中构造函数的参数 1 需要找不到类型 'org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder' 的 bean。

操作：考虑在您的配置中定义类型为 org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder' 的 bean。 这是我的代码。

UserController

package com.panchmeru_studio.controller;

import com.panchmeru_studio.entities.ApplicationUser;
import com.panchmeru_studio.repository.ApplicationUserRepository;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/users")
public class UserController {

    private ApplicationUserRepository applicationUserRepository;
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    public UserController(ApplicationUserRepository applicationUserRepository,
                          BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.applicationUserRepository = applicationUserRepository;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @PostMapping("/record")
    public void signUp(@RequestBody ApplicationUser applicationUser) {
        applicationUser.setPassword(bCryptPasswordEncoder.encode(applicationUser.getPassword()));
        applicationUserRepository.save(applicationUser);
    }
}

SecurityConfiguration.java

package com.panchmeru_studio.security;

import com.panchmeru_studio.filter.AuthenticationFilter;
import com.panchmeru_studio.filter.AuthorizationFilter;

import com.panchmeru_studio.service.ApplicationUserDetailsService;

    public SecurityConfiguration(ApplicationUserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userDetailsService = userDetailsService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable().authorizeRequests()
                .antMatchers(HttpMethod.POST, SIGN_UP_URL).permitAll()
                .anyRequest().authenticated()
                .and()
                .addFilter(new AuthenticationFilter(authenticationManager()))
                .addFilter(new AuthorizationFilter(authenticationManager()))
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }
    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
        return source;
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
    }
    


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


}

Answer 1

错误提示，您没有任何带有密码编码器的 bean。

在你的配置中 class 添加那个 bean 并从 SecurityConfiguration 中的构造函数中删除 BCryptPasswordEncoder:

@Bean
public PasswordEncoder encoder() {
    return new BCryptPasswordEncoder();
}

Answer 2

在您的安全配置 class 中，您不需要这一行：

private BCryptPasswordEncoder bCryptPasswordEncoder;

换成这个。以下方法向 spring 容器提供密码编码器 bean 以加强安全性。

@Bean
public PasswordEncoder passwordEncoder()
{
    return new BCryptPasswordEncoder();
}

在您的控制器中，现在您可以将其自动连接为：

@Autowired    
private BCryptPasswordEncoder bCryptPasswordEncoder;
