Spring Security：无法将我的 UserDetailService 自动连接到 AuthenticationProvider 以进行 BCrypt 集成

[英]Spring Security: Can't Autowire my UserDetailService to AuthenticationProvider for BCrypt integration

 原文  2020-09-10 07:38:44  3   1    java/ spring/ spring-boot/ spring-security

问题描述

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.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。

The base project was created with Spring Initializr and is using Maven.基础项目是使用 Spring Initializr 创建的，并且使用的是 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.它在遵循最基本的教程后工作，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。

My problem is that I can't get the Authentication Provider to use BCrypt and my custom UDS.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。 Here is the relevant code:这是相关的代码：

WebSecurityConfig.java网络安全配置文件

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;
    }

MyUserDetailsService.java MyUserDetailsS​​ervice.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;
    }
}

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.请注意，我没有处理找不到用户的情况，因为这只是一个“沙箱”环境，我正在尝试使基本功能正常工作。 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)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（尽管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）

I tried the answer is this post and a few similar ones, but it still doesn't work.我试过的答案是这个帖子和一些类似的帖子，但它仍然不起作用。 When I Autowire MyCustomUserDetailsService to WebSecurityConfig, my IDE will detect it, but I always get this error message on application startup: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：

The problem is that I don't understand Spring Security well enough yet to troubleshoot this myself.问题是我对 Spring Security 的了解还不够好，无法自己解决这个问题。 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.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。 The error I'm getting seems to be different from the error others with similar problems are getting.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。 Am I even approaching this from the right angle, or is there an entirely better way to do it?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？

Thanks for any help!谢谢你的帮助！

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

Use like this, good luck像这样使用，祝你好运
