找不到的'org.springframework.security.core.userdetails.UserDetailsService'

Question

我正在使用 spring security 基本身份验证，在应用程序启动时出现以下错误：

com.spring.security.firstapp.security.MySecurityConfig 中方法 authManager 的参数 2 需要一个无法找到类型为“org.springframework.security.core.userdetails.UserDetailsService”的 bean。

动作：

考虑在您的配置中定义类型为“org.springframework.security.core.userdetails.UserDetailsService”的 bean。

MySecurityConfig.java

@配置 公开课 MySecurityConfig {

@Autowired
private MyAuthenticationProvider authenticationProvider;

@Bean
public AuthenticationManager authManager(HttpSecurity http, BCryptPasswordEncoder passwordEncoder,
        UserDetailsService userDetailService) throws Exception {
    return http.getSharedObject(AuthenticationManagerBuilder.class)
            .authenticationProvider(authenticationProvider)
            .build();
}

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
    http.httpBasic();
    http.authorizeHttpRequests().anyRequest().authenticated();
    return http.build();

}



@Bean
public static BCryptPasswordEncoder bcryptPasswordEncoder() {
    return new BCryptPasswordEncoder();
}

}

MyAuthenticationProvider.java

@组件 公共类 MyAuthenticationProvider 实现 AuthenticationProvider {

@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
    String userName = authentication.getName();
    String passWord = authentication.getCredentials().toString();
    
    if("tom".equals(userName) && "abc".equals(passWord))
        return new UsernamePasswordAuthenticationToken(userName, passWord);
    else
        throw new BadCredentialsException("Invalid credentials!!");
    
}

@Override
public boolean supports(Class<?> authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
}

}

控制器

@RestController 公共类 HelloController {

@GetMapping("/hello")
public String hello() {
    return "Spring Boot Security";
}

}

我在课堂上添加了豆MySecurityConfig

@Bean
public InMemoryUserDetailsManager userDetailsService(PasswordEncoder passwordEncoder) {
    UserDetails user = User.withUsername("user")
        .password(passwordEncoder.encode("password"))
        .roles("USER")
        .build();

    UserDetails admin = User.withUsername("admin")
        .password(passwordEncoder.encode("admin"))
        .roles("USER", "ADMIN")
        .build();

    return new InMemoryUserDetailsManager(user, admin);
}

运行良好后
