在使用 Spring Security 的 Remember Me 记住密码功能时遇到的问题和解决方法

java.lang.IllegalStateException: UserDetailsService is required.

  • 配置信息(Security.java)
@Autowiredpublic void configureGlobal(AuthenticationManagerBuilder auth) {auth.authenticationProvider(customAuthenticationProvider);}//...@Overrideprotected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers(ROOT_URL, LOGIN_URL, LOGIN_ERROR_URL, CSS_WILDCARD_URL, INDEX_URL).permitAll();http.authorizeRequests().anyRequest().authenticated();http.authorizeRequests().and().rememberMe().rememberMeServices(rememberMeServices()).key(INTERNAL_SECRET_KEY);// ...}@Beanpublic RememberMeServices rememberMeServices() {JdbcTokenRepositoryImpl rememberMeTokenRepository = new JdbcTokenRepositoryImpl();rememberMeTokenRepository.setDataSource(dataSource);PersistentTokenBasedRememberMeServices rememberMeServices =new PersistentTokenBasedRememberMeServices(INTERNAL_SECRET_KEY, userDetailsService(), rememberMeTokenRepository);rememberMeServices.setParameter(REMEMBER_ME);return rememberMeServices;}

错误信息如下，发生该错误的原因是因为没有提供 UserDetailsService 的实例而出错，虽然调用了 userDetailsService() 方法，
但实际上并没有起作用，所以需要提供自定义的 UserDetailsService 实例注入

解决方法：实现 UserDetailsService

  • UserDetailsService.java

}
  • SecurityConfig.java
    // ...// 注入自定义的 UserDetailsService@Autowiredprivate CustomUserDetailsService userDetailsService;@Autowiredpublic void configureGlobal(AuthenticationManagerBuilder auth) {auth.authenticationProvider(customAuthenticationProvider);// 在这里将 UserDetailsSercie 实例注入try {auth.userDetailsService(userDetailsService);} catch (Exception e) {logger.error("Set userDetailService failed, {}", e.getMessage());e.printStackTrace();}}@Overrideprotected void configure(HttpSecurity http) throws Exception {http.authorizeRequests().antMatchers(ROOT_URL, LOGIN_URL, LOGIN_ERROR_URL, CSS_WILDCARD_URL, INDEX_URL).permitAll();http.authorizeRequests().anyRequest().authenticated();http.authorizeRequests().and().rememberMe().rememberMeServices(rememberMeServices()).key(INTERNAL_SECRET_KEY);// ...}@Beanpublic RememberMeServices rememberMeServices() {JdbcTokenRepositoryImpl rememberMeTokenRepository = new JdbcTokenRepositoryImpl();rememberMeTokenRepository.setDataSource(dataSource);// 这里也注入了 UserDetailsSerice 实例PersistentTokenBasedRememberMeServices rememberMeServices =new PersistentTokenBasedRememberMeServices(INTERNAL_SECRET_KEY, userDetailsService, rememberMeTokenRepository);rememberMeServices.setParameter(REMEMBER_ME);return rememberMeServices;}// ...

该异常是因为实现 UserDetailsService 的 loadUserByUsername(String name) 方法时没有考虑查询结果为 null 的情况，导致了空指针异常，
如果用户不存在应当直接抛出 UsernameNotFoundException

  • CustomUserDetailsService.java
    @Overridepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {UserModel user = userMapper.getUserByUsername(username);if (user == null) {logger.error("user {} login failed, the account not exist", username);throw new UsernameNotFoundException("The acccount not exist");} else if (!user.getEnabled()) {logger.error("user {} login failed, this account had expired", username);throw new AccountExpiredException("Account had expired");}// TODO There should add more logic to determine locked, expired and others statuslogger.info("user {} login success", username);// If user is valid put user info to sessionsession.setAttribute(USER, user);return new User(user.getUsername(), user.getPassword(), new ArrayList<GrantedAuthority>());}
