[权限管理系统(四)]-spring boot +spring security短信认证+redis整合

[权限管理系统]spring boot +spring security短信认证+redis整合

  现在主流的登录方式主要有 3 种：账号密码登录、短信验证码登录和第三方授权登录,前面一节Spring security（三）---认证过程已分析了spring security账号密码方式登陆，现在我们来分析一下spring security短信方式认证登陆。

  Spring security 短信方式、IP验证等类似模式登录方式验证，可以根据账号密码方式登录步骤仿写出来，其主要以以下步骤进行展开：

1. 自定义Filter：

2. 自定义Authentication

3. 自定义AuthenticationProvider

4. 自定义UserDetailsService

5. SecurityConfig配置

1. 自定义filter：

  自定义filter可以根据UsernamePasswordAuthenticationFilter过滤器进行仿写，其实质即实现AbstractAuthenticationProcessingFilter抽象类，主要流程分为：

1. 构建构造器，并在构造器中进行配置请求路径以及请求方式的过滤

2. 自定义attemptAuthentication()认证步骤

3. 在2步骤中认证过程中需要AuthenticationProvider进行最终的认证，在认证filter都需要将AuthenticationProvider设置进filter中，而管理AuthenticationProvider的是AuthenticationManager，因此我们创建过滤器filter的时候需要设置AuthenticationManager，这步具体详情在5.1 SecurityConfig配置步骤。

在第2步中attemptAuthentication()认证方法主要进行以下步骤：   

　　1).post请求认证；   

　　2).request请求获取手机号码和验证码；   

　　3).用自定义的Authentication对象封装手机号码和验证码；   

　　4).使用AuthenticationManager.authenticate()方法进行验证。

自定义filter实现代码：

public class SmsAuthenticationfilter extends AbstractAuthenticationProcessingFilter {
    private boolean postOnly = true;
​
    public SmsAuthenticationfilter() {
      super(new AntPathRequestMatcher(SecurityConstants.APP_MOBILE_LOGIN_URL, "POST"));
   }
    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
        if (postOnly && !request.getMethod().equals("POST")) {
              throw new AuthenticationServiceException(
                   "Authentication method not supported: " + request.getMethod());
      }
        Assert.hasText(SecurityConstants.MOBILE_NUMBER_PARAMETER, "mobile parameter must not be empty or null");

         String mobile = request.getParameter(SecurityConstants.MOBILE_NUMBER_PARAMETER);
        String smsCode = request.ge+tParameter(SecurityConstants.MOBILE_VERIFY_CODE_PARAMETER);
        if (mobile == null) {
            mobile="";
        }
        if(smsCode == null){
            smsCode="";
        }
        mobile = mobile.trim();
        smsCode = smsCode.trim();
        SmsAuthenticationToken authRequest = new SmsAuthenticationToken(mobile,smsCode);
​
        // Allow subclasses to set the "details" property
        setDetails(request, authRequest);

        return this.getAuthenticationManager().authenticate(authRequest);
    }protected void setDetails(HttpServletRequest request,
                              SmsAuthenticationToken authRequest) {
        authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
    }
​
    public void setPostOnly(boolean postOnly) {
        this.postOnly = postOnly;
    }
​
}

2. Authentication：

  在filter以及后面的认证都需要使用到自定义的Authentication对象，自定义Authentication对象可以根据UsernamePasswordAuthenticationToken进行仿写，实现AbstractAuthenticationToken抽象类。

自定义SmsAuthenticationToken：

public class SmsAuthenticationToken extends AbstractAuthenticationToken {
​
    private final Object principal;
    private Object credentials;
​
    public SmsAuthenticationToken(Object principal,Object credentials ) {
        super(null);
        this.principal = principal;
        this.credentials=credentials;
        setAuthenticated(false);
    }
​
    public SmsAuthenticationToken(Object principal, Object credentials,Collection<? extends GrantedAuthority> authorities) {
        super(null);
        this.principal = principal;
        this.credentials=credentials;
        setAuthenticated(true);
    }
​
    @Override
    public Object getCredentials() {
        return this.credentials=credentials;
    }
​
    @Override
    public Object getPrincipal() {
        return this.principal;
    }
​
    public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
        if (isAuthenticated) {
            throw new IllegalArgumentException(
                    "Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
        }
​
        super.setAuthenticated(false);
    }
​
    @Override
    public void eraseCredentials() {
        super.eraseCredentials();
​
    }
}

3.AuthenticationProvider

  AuthenticationProvider最终认证策略入口，短信方式验证需自定义AuthenticationProvider。可以根据AbstractUserDetailsAuthenticationProvider进行仿写，实现AuthenticationProvider以及MessageSourceAware接口。认证逻辑可以定义实现。

自定义AuthenticationProvider：

public class SmsAuthenticationProvide implements AuthenticationProvider, MessageSourceAware {
  private UserDetailsService userDetailsService;
  private MessageSourceAccessor messages = SpringSecurityMessageSource.getAccessor();
​
    @Override
    public void setMessageSource(MessageSource messageSource) {
        this.messages = new MessageSourceAccessor(messageSource);
    }
​
    @Override
    public Authentication authenticate(Authentication authentication) {
        Assert.isInstanceOf(SmsAuthenticationToken.class, authentication,
                messages.getMessage(
                        "AbstractUserDetailsAuthenticationProvider.onlySupports",
                        "Only UsernamePasswordAuthenticationToken is supported"));
        SmsAuthenticationToken authenticationToken = (SmsAuthenticationToken) authentication;
        //将验证信息保存在SecurityContext以供UserDetailsService进行验证
        SecurityContext context = SecurityContextHolder.getContext();
        context.setAuthentication(authenticationToken);
        String mobile = (String) authenticationToken.getPrincipal();
        if (mobile == null) {
            throw new InternalAuthenticationServiceException("can't obtain user info ");
        }
        mobile = mobile.trim();
        //进行验证以及获取用户信息
        UserDetails user = userDetailsService.loadUserByUsername(mobile);
        if (user == null) {
            throw new InternalAuthenticationServiceException("can't obtain user info ");
        }
        SmsAuthenticationToken smsAuthenticationToken = new SmsAuthenticationToken(user, user.getAuthorities());
        return smsAuthenticationToken;
    }
​
    @Override
    public boolean supports(Class<?> authentication) {
        return (SmsAuthenticationToken.class.isAssignableFrom(authentication));
    }
​
    public void setUserDetailsService(UserDetailsService userDetailsService) {
        this.userDetailsService = userDetailsService;
    }
​
    public UserDetailsService getUserDetailsService() {
        return userDetailsService;
    }
}

4. UserDetailsService

  在AuthenticationProvider最终认证策略入口，认证方式实现逻辑是在UserDetailsService。可以根据自己项目自定义认证逻辑。

自定义UserDetailsService：

public class SmsUserDetailsService implements UserDetailsService {
    @Autowired
    private RedisUtil redisUtil;
​
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        //从SecurityContext获取认证所需的信息（手机号码、验证码）
        SecurityContext context = SecurityContextHolder.getContext();
        SmsAuthenticationToken authentication = (SmsAuthenticationToken) context.getAuthentication();
        if(!additionalAuthenticationChecks(username,authentication)){
            return null;
        }
        //获取用户手机号码对应用户的信息，包括权限等
        return new User("admin", "123456", Arrays.asList(new SimpleGrantedAuthority("admin")));
    }
​
    public boolean additionalAuthenticationChecks(String mobile, SmsAuthenticationToken smsAuthenticationToken) {
        //获取redis中手机键值对应的value验证码
        String smsCode = redisUtil.get(mobile).toString();
        //获取用户提交的验证码
        String credentials = (String) smsAuthenticationToken.getCredentials();
        if(StringUtils.isEmpty(credentials)){
            return false;
        }
        if (credentials.equalsIgnoreCase(smsCode)) {
            return true;
        }
        return false;
    }
}

5.SecurityConfig

5.1 自定义Sms短信验证组件配置SecurityConfig

  将自定义组件配置SecurityConfig中，可以根据AbstractAuthenticationFilterConfigurer(子类FormLoginConfigurer)进行仿写SmsAuthenticationSecurityConfig，主要进行以下配置：

1. 将默认AuthenticationManager（也可以定义的）设置到自定义的filter过滤器中

2. 将自定义的UserDetailsService设置到自定义的AuthenticationProvide中以供使用

3. 将过滤器添加到过滤链路中，实施过滤操作。（一般以加在UsernamePasswordAuthenticationFilter前）

配置SmsAuthenticationSecurityConfig:

 @Component
 public class SmsAuthenticationSecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
    @Autowired
    private UserDetailsService userDetailsService;
​
    @Override
    public void configure(HttpSecurity http) throws Exception {
        //创建并配置好自定义SmsAuthenticationfilter，
        SmsAuthenticationfilter smsAuthenticationfilter = new SmsAuthenticationfilter();
        smsAuthenticationfilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
        smsAuthenticationfilter.setAuthenticationSuccessHandler(customAuthenticationSuccessHandler());
        smsAuthenticationfilter.setAuthenticationFailureHandler(customAuthenticationFailureHandler());
        //创建并配置好自定义SmsAuthenticationProvide
        SmsAuthenticationProvide smsAuthenticationProvide=new SmsAuthenticationProvide();
        smsAuthenticationProvide.setUserDetailsService(userDetailsService);
        http.authenticationProvider(smsAuthenticationProvide);
        //将过滤器添加到过滤链路中
        http.addFilterAfter(smsAuthenticationfilter, UsernamePasswordAuthenticationFilter.class);
    }
​
    @Bean
    public CustomAuthenticationSuccessHandler customAuthenticationSuccessHandler() {
        return new CustomAuthenticationSuccessHandler();
    }

    @Bean
    public CustomAuthenticationFailureHandler customAuthenticationFailureHandler() {
        return new CustomAuthenticationFailureHandler();
    }
}

5.2 SecurityConfig主配置

  SecurityConfig主配置可以参照第二节Spring Security（二）--WebSecurityConfigurer配置以及filter顺序进行配置。

SecurityConfig主配置：

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private SmsAuthenticationSecurityConfig smsAuthenticationSecurityConfig;
    @Autowired
    private CustomAuthenticationSuccessHandler authenticationSuccessHandler;
    @Autowired
    private CustomAuthenticationFailureHandler authenticationFailureHandler;
​
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.headers().frameOptions().disable().and()
                .formLogin()
                .loginPage(SecurityConstants.APP_FORM_LOGIN_PAGE)
                //配置form登陆的自定义URL
                .loginProcessingUrl(SecurityConstants.APP_FORM_LOGIN_URL)
                .successHandler(authenticationSuccessHandler)
                .failureHandler(authenticationFailureHandler)
                .and()
                //配置smsAuthenticationSecurityConfig
                .apply(smsAuthenticationSecurityConfig)
                .and()
                //运行通过URL
                .authorizeRequests()
                .antMatchers(SecurityConstants.APP_MOBILE_VERIFY_CODE_URL,
                             SecurityConstants.APP_USER_REGISTER_URL)
                .permitAll()
                .and()
                .csrf().disable();
    }
    @Bean
    public ObjectMapper objectMapper(){
        return new ObjectMapper();
    }
}

public class RedisUtil {
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;
    /**
     * 普通缓存获取
     *
     * @param key 键
     * @return 值
     */
    public Object get(String key) {
        return key == null ? null : redisTemplate.opsForValue().get(key);
    }
​
    /**

     * @return true成功 false失败
     */
    public boolean set(String key, Object value) {
        try {
            redisTemplate.opsForValue().set(key, value);
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }

            if (time > 0) {
                redisTemplate.opsForValue().set(key, value, time, TimeUnit.SECONDS);
            } else {
                set(key, value);
            }
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }
 }

redisConfig配置类：

@Configuration
public class RedisConfig {
@Autowired
private RedisProperties properties;
@Bean
@SuppressWarnings("all")
@ConditionalOnClass(RedisConnectionFactory.class)
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(factory);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        template.afterPropertiesSet();
        return template;
    }
    @Bean
    @Qualifier("redisConnectionFactory")

        //redis连接池数据设置
        JedisClientConfiguration.JedisClientConfigurationBuilder builder = JedisClientConfiguration.builder();
        if (this.properties.getTimeout() != null) {
            Duration timeout = this.properties.getTimeout();
            builder.readTimeout(timeout).connectTimeout(timeout);
        }
        RedisProperties.Pool pool = this.properties.getJedis().getPool();
        if (pool != null) {
            builder.usePooling().poolConfig(this.jedisPoolConfig(pool));
        }
        JedisClientConfiguration jedisClientConfiguration = builder.build();
        //根据两个配置类生成JedisConnectionFactory
        return new JedisConnectionFactory(redisConfig,jedisClientConfiguration);
​
    }
    private JedisPoolConfig jedisPoolConfig(RedisProperties.Pool pool) {
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(pool.getMaxActive());
        config.setMaxIdle(pool.getMaxIdle());
        config.setMinIdle(pool.getMinIdle());
        if (pool.getMaxWait() != null) {
            config.setMaxWaitMillis(pool.getMaxWait().toMillis());
        }
        return config;
    }
} 

7.总结

  可以根据短信验证登陆模式去实现类似的验证方式，可以结合本节的例子进行跟项目结合起来，减少开发时间。后续还有第三方登陆方式分析以案例。最后错误请评论指出！
