【中文标题】Spring Security:无法将我的 UserDetailService 自动连接到 AuthenticationProvider 以进行 BCrypt 集成【英文标题】:Spring Security: Can't Autowire my UserDetailService to AuthenticationProvider for BCrypt integration 【发布时间】:2020-12-28 16:09:35 【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 UserDetailsService 从数据库中获取用户名和加密密码,登录完成。
基础项目是使用 Spring Initializr 创建的,并且使用的是 Maven。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。
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。以下是相关代码:
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;
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,我不会处理找不到用户的情况,因为这只是一个“沙盒”环境,我试图让基本功能正常工作。正如评论中所说,当我尝试登录时,数据库工作并且控制台打印出有效的 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,但这个问题是另一天的问题)
我尝试了the answer is this post 和一些类似的,但仍然无法正常工作。当我将 MyCustomUserDetailsService 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:

问题是我对 Spring Security 的理解还不够好,无法自己解决这个问题。所有的教程都显示它有点不同,对于一些它就像我在这里一样,至少在我看来是这样的。我得到的错误似乎与其他有类似问题的错误不同。我什至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?
感谢您的帮助!
【问题讨论】:
【参考方案1】:@Bean(name = "passwordEncoder")
@Qualifier("passwordEncoder")
public PasswordEncoder passwordEncoder()
return PasswordEncoderFactories.createDelegatingPasswordEncoder();
这样使用,祝你好运
【讨论】:
我觉得这让我更进一步,谢谢,但现在我得到“java.lang.IllegalArgumentException:没有为 id “null”映射 PasswordEncoder” 关注:***.com/questions/49654143/… 这似乎与我的代码非常不同。你能告诉我我必须在我的代码中的哪个位置添加该帖子的答案吗? 只需将您的 PasswordEncoder bean 替换为 PasswordEncoderFactories.createDelegatingPasswordEncoder()以上是关于Spring Security:无法将我的 UserDetailService 自动连接到 AuthenticationProvider 以进行 BCrypt 集成的主要内容,如果未能解决你的问题,请参考以下文章
