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：
- 自定义Filter：
- 自定义Authentication
- 自定义AuthenticationProvider
- 自定义UserDetailsService
- 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：
- 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
- 自定义attemptAuthentication()认证步骤
- 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 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：
- 将默认AuthenticationManager（也可以定义的）设置到自定义的filter过滤器中
- 将自定义的UserDetailsService设置到自定义的AuthenticationProvide中以供使用
- 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 {
@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();
}
}

6.1 redis
RedisUtil工具类：
@Component
public class RedisUtil {
@Autowired
private RedisTemplate 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);
}
/**
* 普通缓存放入
*
* @param key 键

*/
public boolean set(String key, Object value) {
try {
redisTemplate.opsForValue().set(key, value);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
/**
* 普通缓存放入并设置时间
*
* @param key 键
* @param value 值
* @param time 时间(秒) time要大于0 如果time小于等于0 将设置无限期
* @return true成功 false 失败
*/
public boolean set(String key, Object value, long time) {
try {
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：

public class RedisConfig {
@Autowired
private RedisProperties properties;
@Bean
@SuppressWarnings("all")
@ConditionalOnClass(RedisConnectionFactory.class)
public RedisTemplate redisTemplate(RedisConnectionFactory factory) {
RedisTemplate template = new RedisTemplate();
template.setConnectionFactory(factory);

ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
// key采用String的序列化方式
template.setKeySerializer(stringRedisSerializer);
// hash的key也采用String的序列化方式
template.setHashKeySerializer(stringRedisSerializer);
// value序列化方式采用jackson
template.setValueSerializer(jackson2JsonRedisSerializer);
// hash的value序列化方式采用jackson
template.setHashValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}
@Bean
@Qualifier("redisConnectionFactory")
public RedisConnectionFactory redisConnectionFactory(){
RedisStandaloneConfiguration redisConfig = new RedisStandaloneConfiguration();
redisConfig.setHostName(properties.getHost());
redisConfig.setPort(properties.getPort());
redisConfig.setPassword(RedisPassword.of(properties.getPassword()));
redisConfig.setDatabase(properties.getDatabase());
//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！
