错误：需要“org”类型的bean。springframework。安全加密。bcrypt公司。找不到BCryptPasswordEncoder“”

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，但我在运行y应用程序时收到这些错误

说明：com中构造函数的参数1。panchmeru\u工作室。控制器。UserController需要“org”类型的bean。springframework。安全加密。bcrypt公司。找不到BCryptPasswordEncoder“”。

操作：考虑定义一个org类型的bean。springframework。安全加密。bcrypt公司。配置中的“BCryptPasswordEncoder”。这是我的密码。

用户控制器

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);
    }
}

安全配置。Java语言

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

错误显示，您没有任何带有密码编码器的bean。

在confugiration类中，在SecurityConfiguration中添加该bean并从构造函数中删除BCryptPasswordEncoder：

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

Answer 2

在安全配置类中，不需要此行：

private BCryptPasswordEncoder bCryptPasswordEncoder;

将其替换为此。下面的方法是向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装配为：

@Autowired    
private BCryptPasswordEncoder bCryptPasswordEncoder;
