本文介绍了Spring Security:无法将我的 UserDetailService 自动连接到 AuthenticationProvider 以进行 BCrypt 集成的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用 Spring Security 为我的应用程序创建一个非常简单的登录功能:用户注册、用户名和 BCrypt 加密密码保存到数据库中，用户输入凭据，自定义 UserDetailsS​​ervice 从数据库中获取用户名和加密密码，登录完成.

I'm trying to create a very simple login functionality for my app with Spring Security: User registers, username and BCrypt encrypted password are saved to a database, user enters credentials, custom UserDetailsService gets username and encrypted password from the database, login complete.

基础项目是使用 Spring Initializr 创建的，并且使用的是 Maven.在遵循最基本的教程之后它就可以工作了，没有数据库，只有一个硬编码用户，但是当我添加加密时，问题就开始了.

The base project was created with Spring Initializr and is using Maven. It worked after following the most basic tutorial, with no database and only one hardcoded user, but when I added encryption, the problems started.

我的问题是我无法让身份验证提供程序使用 BCrypt 和我的自定义 UDS.相关代码如下:

My problem is that I can't get the Authentication Provider to use BCrypt and my custom UDS. Here is the relevant code:

WebSecurityConfig.java

WebSecurityConfig.java

package com.example.demo;

imports...

@Configuration
@ComponentScan(basePackages = { "com.example.demo" })
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/", "/main", "/register").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
                .logout()
                .permitAll();
    }


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

    // If I leave out the part below, there is no error when starting the program, but a login attempt
    // will fail and the program will output that the password doesn`t look like BCrypt

    @Autowired
    MyUserDetailsService myUserDetailsService;

    @Bean
    public DaoAuthenticationProvider authProvider() {
        DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
        authProvider.setUserDetailsService(myUserDetailsService);
        authProvider.setPasswordEncoder(encoder());
        return authProvider;
    }

MyUserDetailsS​​ervice.java

MyUserDetailsService.java

package com.example.demo;

imports...

import java.util.Optional;

@Service("myUserDetailsService")
public class MyUserDetailsService implements UserDetailsService {

    @Autowired
    UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {

        Optional<UserDB> userDB = userRepository.findById(s);

        User user = null;

        if (userDB.isPresent()) {
            System.out.println("present!");
            UserDB userDB2 = userDB.get();
            System.out.println(userDB2.getPassword());
            // The line above prints a valid BCrypt password with 60 characters
            user = new User(userDB2.getUsername(), userDB2.getPassword());
        }


        return user;
    }
}

请注意，我不处理找不到用户的情况，因为这只是一个沙箱"；我试图让基本功能发挥作用的环境.正如评论中一样，当我尝试登录时，数据库可以工作并且控制台会打印有效的 BCrypt(虽然它似乎不是永久性的，并且在我重新启动应用程序时不起作用，但该问题是另一天)

Note that I'm not handling the case where a user isn't found because this is just a "sandbox" environment where I'm trying to get the base functionality to work. As in the comment, the database works and the console prints valid BCrypt when I try to log in (although it seems like it's not permanent and doesn't work when I restart the app, but that problem is for another day)

我尝试了答案是这篇文章和一些类似的文章，但它仍然不起作用.当我将 MyCustomUserDetailsS​​ervice 自动连接到 WebSecurityConfig 时，我的 IDE 会检测到它，但我总是在应用程序启动时收到此错误消息:

I tried the answer is this post and a few similar ones, but it still doesn't work. When I Autowire MyCustomUserDetailsService to WebSecurityConfig, my IDE will detect it, but I always get this error message on application startup:

问题是我对 Spring Security 的了解还不够好，无法自己解决这个问题.所有的教程都以不同的方式展示了它，对于某些教程来说，它就像我在这里一样工作，至少在我看来是这样.我得到的错误似乎与其他有类似问题的人得到的错误不同.我是从正确的角度来解决这个问题，还是有更好的方法来做到这一点?

The problem is that I don't understand Spring Security well enough yet to troubleshoot this myself. All the tutorials show it a bit differently, and for some it just works like I have it here, at least that's what it looks like to me. The error I'm getting seems to be different from the error others with similar problems are getting. Am I even approaching this from the right angle, or is there an entirely better way to do it?

感谢您的帮助！

推荐答案

@Bean(name = "passwordEncoder")
    @Qualifier("passwordEncoder")
    public PasswordEncoder passwordEncoder() {
        return PasswordEncoderFactories.createDelegatingPasswordEncoder();
    }

这样使用，祝你好运

这篇关于Spring Security:无法将我的 UserDetailService 自动连接到 AuthenticationProvider 以进行 BCrypt 集成的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
