public class CustomUserDetails implements UserDetails {private String email;private boolean enabled;private ListGrantedAuthority authorities;public CustomUserDetails(String email, boolean enabled, ListGrantedAuthority authorities) {this.email email;this.enabled enabled;this.authorities authorities;}// Implement other UserDetails methods...Overridepublic String getUsername() {return email;}// Getters and setters...
}
Step 2: 创建自定义过滤器 创建一个自定义的过滤器用于处理邮箱验证码登录逻辑。这个过滤器将在用户登录时验证邮箱和验证码并完成用户认证过程。
public class EmailVerificationAuthenticationFilter extends AbstractAuthenticationProcessingFilter {public EmailVerificationAuthenticationFilter() {super(new AntPathRequestMatcher(/login/email, POST));}Overridepublic Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)throws AuthenticationException {String email obtainEmail(request);String verificationCode obtainVerificationCode(request);email (email ! null) ? email.trim() : ;verificationCode (verificationCode ! null) ? verificationCode.trim() : ;EmailVerificationToken authRequest new EmailVerificationToken(email, verificationCode);return this.getAuthenticationManager().authenticate(authRequest);}private String obtainEmail(HttpServletRequest request) {return request.getParameter(email);}private String obtainVerificationCode(HttpServletRequest request) {return request.getParameter(verificationCode);}
}
Step 3: 创建自定义认证令牌 创建一个自定义的认证令牌继承自UsernamePasswordAuthenticationToken用于封装用户的邮箱和验证码信息。
public class EmailVerificationToken extends UsernamePasswordAuthenticationToken {private final String email;private final String verificationCode;public EmailVerificationToken(String email, String verificationCode) {super(email, verificationCode);this.email email;this.verificationCode verificationCode;}public String getEmail() {return email;}public String getVerificationCode() {return verificationCode;}
}
Step 4: 实现自定义AuthenticationProvider 创建一个自定义的AuthenticationProvider用于处理邮箱验证登录的认证逻辑。
Component
public class EmailVerificationAuthenticationProvider implements AuthenticationProvider {Overridepublic Authentication authenticate(Authentication authentication) throws AuthenticationException {String email authentication.getName();String verificationCode authentication.getCredentials().toString();// 在此处编写您的自定义认证逻辑// 比如根据email和verificationCode验证用户信息if (authenticationIsValid) {ListGrantedAuthority authorities new ArrayList();authorities.add(new SimpleGrantedAuthority(ROLE_USER));CustomUserDetails userDetails new CustomUserDetails(email, true, authorities);return new UsernamePasswordAuthenticationToken(userDetails, null, authorities);} else {throw new AuthenticationServiceException(Authentication failed);}}Overridepublic boolean supports(Class? authentication) {return EmailVerificationToken.class.isAssignableFrom(authentication);}
}
Step 5: 实现自定义UserDetailsService 创建一个实现UserDetailsService接口的类用于根据邮箱查询用户信息。
Service
public class CustomUserDetailsService implements UserDetailsService {private final UserRepository userRepository;Autowiredpublic CustomUserDetailsService(UserRepository userRepository) {this.userRepository userRepository;}Overridepublic UserDetails loadUserByUsername(String email) throws UsernameNotFoundException {// 在此处实现根据邮箱查询用户信息的逻辑CustomUser user userRepository.findByEmail(email);if (user null) {throw new UsernameNotFoundException(User not found with email: email);}ListGrantedAuthority authorities new ArrayList();authorities.add(new SimpleGrantedAuthority(ROLE_USER));return new CustomUserDetails(user.getEmail(), user.isEnabled(), authorities);}
}
Step 6: 配置Spring Security 在Spring Security配置类中配置自定义过滤器、认证提供者和UserDetailsService。
Configuration
EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {private final EmailVerificationAuthenticationProvider emailVerificationAuthenticationProvider;private final CustomUserDetailsService customUserDetailsService;Autowiredpublic SecurityConfig(EmailVerificationAuthenticationProvider emailVerificationAuthenticationProvider, CustomUserDetailsService customUserDetailsService) {this.emailVerificationAuthenticationProvider emailVerificationAuthenticationProvider;this.customUserDetailsService customUserDetailsService;}Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {auth.authenticationProvider(emailVerificationAuthenticationProvider);auth.userDetailsService(customUserDetailsService).passwordEncoder(passwordEncoder());}Overrideprotected void configure(HttpSecurity http) throws Exception {http.addFilterBefore(emailVerificationAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class).authorizeRequests().antMatchers(/login).permitAll().anyRequest().authenticated().and().formLogin().loginPage(/login).defaultSuccessUrl(/dashboard).and().logout().logoutUrl(/logout).logoutSuccessUrl(/login);}Beanpublic EmailVerificationAuthenticationFilter emailVerificationAuthenticationFilter() throws Exception {EmailVerificationAuthenticationFilter filter new EmailVerificationAuthenticationFilter();filter.setAuthenticationManager(authenticationManagerBean());return filter;}Beanpublic PasswordEncoder passwordEncoder() {return NoOpPasswordEncoder.getInstance(); // For simplicity, use NoOpPasswordEncoder}
}
