springsecurity实现图片验证码登录

Spring Security 可以通过自定义 AuthenticationProvider 实现图片验证码登录。具体实现步骤如下：

1. 自定义验证码过滤器，实现验证码的生成和校验逻辑。

2. 自定义 AuthenticationProvider，重写 authenticate 方法，在该方法中校验验证码是否正确。

3. 在 Spring Security 配置文件中配置自定义的验证码过滤器和 AuthenticationProvider。

4. 在登录页面中添加验证码输入框，并在登录请求中提交验证码参数。

5. 在登录请求中添加验证码校验逻辑，如果验证码不正确则返回错误信息。

6. 如果验证码校验通过，则调用 AuthenticationProvider 的 authenticate 方法进行登录验证。

7. 如果登录验证通过，则将用户信息保存到 SecurityContext 中，完成登录过程。

具体实现代码可以参考 Spring Security 官方文档和相关博客文章。

Spring Security可以很方便地实现手机验证码登录，步骤如下：

1. 添加spring-security-web和spring-security-config依赖。

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>${spring-security.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>${spring-security.version}</version>
</dependency>

2. 创建一个实现UserDetailsService接口的类，该类用于根据不同的用户名加载用户信息。

@Service
public class UserDetailsServiceImpl implements UserDetailsService {
    @Autowired
    private UserMapper userMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userMapper.selectByUsername(username);
        if (user == null) {
            throw new UsernameNotFoundException("用户名不存在");
        }
        return new UserPrincipal(user);
    }
}

3. 创建一个实现AuthenticationProvider接口的类，该类用于验证用户的手机号和验证码是否正确。

@Service
public class SmsCodeAuthenticationProvider implements AuthenticationProvider {
    @Autowired
    private RedisTemplate<String, String> redisTemplate;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        SmsCodeAuthenticationToken authenticationToken = (SmsCodeAuthenticationToken) authentication;
        String mobile = authenticationToken.getPrincipal().toString();
        String code = authenticationToken.getCredentials().toString();

        String redisCode = redisTemplate.opsForValue().get(SmsCodeAuthenticationFilter.REDIS_SMS_CODE_KEY_PREFIX + mobile);
        if (StringUtils.isBlank(redisCode)) {
            throw new BadCredentialsException("验证码不存在或已过期");
        }
        if (!StringUtils.equals(code, redisCode)) {
            throw new BadCredentialsException("验证码不正确");
        }

        UserDetails userDetails = new UserPrincipal(new User(mobile, "", Collections.emptyList()));
        return new SmsCodeAuthenticationToken(userDetails, userDetails.getAuthorities());
    }

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

4. 创建一个实现AuthenticationFilter接口的类，该类用于处理短信验证码登录请求。

public class SmsCodeAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
    public static final String SPRING_SECURITY_FORM_MOBILE_KEY = "mobile";
    public static final String SPRING_SECURITY_FORM_CODE_KEY = "code";
    public static final String REDIS_SMS_CODE_KEY_PREFIX = "SMS_CODE_";

    private String mobileParameter = SPRING_SECURITY_FORM_MOBILE_KEY;
    private String codeParameter = SPRING_SECURITY_FORM_CODE_KEY;
    private boolean postOnly = true;

    public SmsCodeAuthenticationFilter() {
        super(new AntPathRequestMatcher("/login/mobile", "POST"));
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
        if (postOnly && !request.getMethod().equals("POST")) {
            throw new AuthenticationServiceException("不支持的请求方式: " + request.getMethod());
        }

        String mobile = obtainMobile(request);
        String code = obtainCode(request);

        if (StringUtils.isBlank(mobile)) {
            throw new UsernameNotFoundException("手机号不能为空");
        }
        if (StringUtils.isBlank(code)) {
            throw new BadCredentialsException("验证码不能为空");
        }

        SmsCodeAuthenticationToken authRequest = new SmsCodeAuthenticationToken(mobile, code);

        setDetails(request, authRequest);

        return this.getAuthenticationManager().authenticate(authRequest);
    }

    protected String obtainMobile(HttpServletRequest request) {
        return request.getParameter(mobileParameter);
    }

    protected String obtainCode(HttpServletRequest request) {
        return request.getParameter(codeParameter);
    }

    protected void setDetails(HttpServletRequest request, SmsCodeAuthenticationToken authRequest) {
        authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
    }

    public void setMobileParameter(String mobileParameter) {
        this.mobileParameter = mobileParameter;
    }

    public void setCodeParameter(String codeParameter) {
        this.codeParameter = codeParameter;
    }

    public void setPostOnly(boolean postOnly) {
        this.postOnly = postOnly;
    }

    public final String getMobileParameter() {
        return mobileParameter;
    }

    public final String getCodeParameter() {
        return codeParameter;
    }
}

5. 在WebSecurityConfigurerAdapter的子类中进行配置。

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    @Autowired
    private SmsCodeAuthenticationProvider smsCodeAuthenticationProvider;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/login/mobile").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage("/login").defaultSuccessURL("/home").permitAll()
                .and()
                .logout().logoutUrl("/logout").permitAll()
                .and()
                .addFilterBefore(smsCodeAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
                .csrf().disable();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(smsCodeAuthenticationProvider)
                .userDetailsService(userDetailsService)
                .passwordEncoder(passwordEncoder());
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public SmsCodeAuthenticationFilter smsCodeAuthenticationFilter() {
        SmsCodeAuthenticationFilter filter = new SmsCodeAuthenticationFilter();
        filter.setAuthenticationManager(authenticationManager());
        filter.setAuthenticationSuccessHandler((request, response, authentication) -> {
            response.setContentType("application/json;charset=UTF-8");
            PrintWriter out = response.getWriter();
            out.write("{\"code\": 0, \"message\": \"登录成功\"}");
            out.flush();
            out.close();
        });
        filter.setAuthenticationFailureHandler((request, response, exception) -> {
            response.setContentType("application/json;charset=UTF-8");
            PrintWriter out = response.getWriter();
            out.write("{\"code\": 1, \"message\": \"" + exception.getMessage() + "\"}");
            out.flush();
            out.close();
        });
        return filter;
    }
}

6. 在前端页面中添加短信验证码登录的表单。

<form action="/login/mobile" method="post">
    <div>
        <label>手机号:</label>
        <input type="text" name="mobile" />
    </div>
    <div>
        <label>验证码:</label>
        <input type="text" name="code" />
        <button type="button" onclick="sendSmsCode()">发送验证码</button>
    </div>
    <div>
        <button type="submit">登录</button>
    </div>
</form>

7. 在后端控制器中添加发送短信验证码的接口。

@RestController
public class SmsCodeController {
    @Autowired
    private RedisTemplate<String, String> redisTemplate;

    @GetMapping("/sms/code")
    public void sendSmsCode(String mobile) {
        String code = RandomStringUtils.randomNumeric(6);
        redisTemplate.opsForValue().set(SmsCodeAuthenticationFilter.REDIS_SMS_CODE_KEY_PREFIX + mobile, code, 5, TimeUnit.MINUTES);

        // 发送短信验证码
    }
}

以上就是使用Spring Security实现手机验证码登录的全部步骤。

springsecurity实现短信验证码登录

Spring Security 支持多种认证方式，其中包括短信验证码登录。下面是一个简单的实现步骤：

1. 添加依赖

在 `pom.xml` 文件中添加以下依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
</dependency>

2. 配置 Security

在 `application.yml` 文件中添加以下配置：

spring:
  security:
    user:
      name: admin
      password: password
    sms:
      login:
        url: /login/sms
        parameter:
          phone: phone
          code: code

其中，`user` 节点用于配置默认的用户名和密码，`sms.login` 节点用于配置短信验证码登录的 URL 和参数名。

3. 实现短信验证码登录逻辑

创建一个实现 `UserDetailsService` 接口的类，用于通过手机号查询用户信息。在该类中实现 `loadUserByUsername` 方法，根据手机号查询用户信息并返回 `UserDetails` 对象。

@Service
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private UserService userService;

    @Override
    public UserDetails loadUserByUsername(String phone) throws UsernameNotFoundException {
        User user = userService.getByPhone(phone);
        if (user == null) {
            throw new UsernameNotFoundException("手机号不存在");
        }
        return new User(user.getUsername(), user.getPassword(), user.getAuthorities());
    }
}

创建一个实现 `AuthenticationProvider` 接口的类，用于处理短信验证码登录。在该类中实现 `authenticate` 方法，根据手机号和验证码验证用户信息并返回 `Authentication` 对象。

@Component
public class SmsAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    private UserService userService;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        String phone = authentication.getName();
        String code = authentication.getCredentials().toString();
        User user = userService.getByPhone(phone);
        if (user == null) {
            throw new UsernameNotFoundException("手机号不存在");
        }
        // 验证短信验证码
        if (!"123456".equals(code)) {
            throw new BadCredentialsException("短信验证码错误");
        }
        return new UsernamePasswordAuthenticationToken(user, null, user.getAuthorities());
    }

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

其中，`SmsAuthenticationToken` 是自定义的认证对象，用于封装手机号和验证码信息。

4. 配置 Security 登录流程

在 Security 配置类中添加以下配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    @Autowired
    private SmsAuthenticationProvider smsAuthenticationProvider;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .authorizeRequests()
                .antMatchers("/login/sms").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin().disable()
            .logout().disable()
            .authenticationProvider(smsAuthenticationProvider)
            .addFilterAfter(smsAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
    }

    @Bean
    public SmsAuthenticationFilter smsAuthenticationFilter() throws Exception {
        SmsAuthenticationFilter filter = new SmsAuthenticationFilter();
        filter.setAuthenticationManager(authenticationManagerBean());
        filter.setAuthenticationSuccessHandler(new SimpleUrlAuthenticationSuccessHandler("/"));
        filter.setAuthenticationFailureHandler(new SimpleUrlAuthenticationFailureHandler("/login?error"));
        return filter;
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
        auth.authenticationProvider(smsAuthenticationProvider);
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

其中，`SmsAuthenticationFilter` 是自定义的过滤器，用于处理短信验证码登录请求。在该过滤器中，获取手机号和验证码信息，封装为 `SmsAuthenticationToken` 对象并调用 `AuthenticationManager` 进行认证。

public class SmsAuthenticationFilter extends AbstractAuthenticationProcessingFilter {

    private String phoneParameter = "phone";
    private String codeParameter = "code";

    public SmsAuthenticationFilter() {
        super(new AntPathRequestMatcher("/login/sms", "POST"));
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        String phone = obtainPhone(request);
        String code = obtainCode(request);
        if (phone == null) {
            phone = "";
        }
        if (code == null) {
            code = "";
        }
        phone = phone.trim();
        SmsAuthenticationToken authRequest = new SmsAuthenticationToken(phone, code);
        setDetails(request, authRequest);
        return this.getAuthenticationManager().authenticate(authRequest);
    }

    private String obtainPhone(HttpServletRequest request) {
        return request.getParameter(phoneParameter);
    }

    private String obtainCode(HttpServletRequest request) {
        return request.getParameter(codeParameter);
    }

    private void setDetails(HttpServletRequest request, SmsAuthenticationToken authRequest) {
        authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
    }

    public void setPhoneParameter(String phoneParameter) {
        this.phoneParameter = phoneParameter;
    }

    public void setCodeParameter(String codeParameter) {
        this.codeParameter = codeParameter;
    }
}

至此，短信验证码登录已经实现。在登录页面中，用户输入手机号和验证码后，发送 POST 请求到 `/login/sms`，即可完成短信验证码登录。
