spring security自定义认证登录的全过程记录

spring security使用分类：

如何使用spring security，相信百度过的都知道，总共有四种用法，从简到深为：

1、不用数据库，全部数据写在配置文件，这个也是官方文档里面的demo；

2、使用数据库，根据spring security默认实现代码设计数据库，也就是说数据库已经固定了，这种方法不灵活，而且那个数据库设计得很简陋，实用性差；

3、spring security和Acegi不同，它不能修改默认filter了，但支持插入filter，所以根据这个，我们可以插入自己的filter来灵活使用；

4、暴力手段，修改源码，前面说的修改默认filter只是修改配置文件以替换filter而已，这种是直接改了里面的源码，但是这种不符合OO设计原则，而且不实际，不可用。

本文主要介绍了关于spring security自定义认证登录的相关内容，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。

1.概要

1.1.简介

spring security是一种基于 Spring AOP 和 Servlet 过滤器的安全框架，以此来管理权限认证等。

1.2.spring security 自定义认证流程

1）认证过程

生成未认证的AuthenticationToken

 ↑（获取信息）  （根据AuthenticationToken分配provider）     
 AuthenticationFilter -> AuthenticationManager -> AuthenticationProvider
 ↓（认证）
UserDetails（一般查询数据库获取）
 ↓（通过）
 生成认证成功的AuthenticationToken
  ↓（存放）
 SecurityContextHolder

2）将AuthenticationFilter加入到security过滤链（资源服务器中配置），如：

http.addFilterBefore(AuthenticationFilter, AbstractPreAuthenticatedProcessingFilter.class)

或者：

http.addFilterAfter(AuthenticationFilter, UsernamePasswordAuthenticationFilter.class)

2.以手机号短信登录为例

2.1.开发环境

SpringBoot
Spring security
Redis

2.2.核心代码分析

2.2.1.自定义登录认证流程

2.2.1.1.自定义认证登录Token


public class MobileLoginAuthenticationToken extends AbstractAuthenticationToken {
 private static final long serialVersionUID = SpringSecurityCoreVersion.SERIAL_VERSION_UID;
 private static final Logger logger = LoggerFactory.getLogger(MobileLoginAuthenticationToken.class.getName());
 private final Object principal;
 public MobileLoginAuthenticationToken(String mobile) {
 super(null);
 this.principal = mobile;
 this.setAuthenticated(false);
 logger.info("MobileLoginAuthenticationToken setAuthenticated ->false loading ...");
 }
 public MobileLoginAuthenticationToken(Object principal,
      Collection authorities) {
 super(authorities);
 this.principal = principal;
 // must use super, as we override
 super.setAuthenticated(true);
 logger.info("MobileLoginAuthenticationToken setAuthenticated ->true loading ...");
 }
 @Override
 public void setAuthenticated(boolean authenticated) {
 if (authenticated) {
  throw new IllegalArgumentException(
   "Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
 }
 super.setAuthenticated(false);
 }
 @Override
 public Object getCredentials() {
 return null;
 }
 @Override
 public Object getPrincipal() {
 return this.principal;
 }
 @Override
 public void eraseCredentials() {
 super.eraseCredentials();
 }
}

注：

setAuthenticated()：判断是否已认证

在过滤器时，会生成一个未认证的AuthenticationToken，此时调用的是自定义token的setAuthenticated()，此时设置为false -> 未认证
在提供者时，会生成一个已认证的AuthenticationToken，此时调用的是父类的setAuthenticated()，此时设置为true -> 已认证

2.2.1.1.自定义认证登录过滤器


public class MobileLoginAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
 private boolean postonly = true;
 private static final Logger logger = LoggerFactory.getLogger(MobileLoginAuthenticationFilter.class.getName());
 @Getter
 @Setter
 private String mobileParameterName;
 public MobileLoginAuthenticationFilter(String mobileLoginUrl, String mobileParameterName,
      String httpMethod) {
 super(new AntPathRequestMatcher(mobileLoginUrl, httpMethod));
 this.mobileParameterName = mobileParameterName;
 logger.info("MobileLoginAuthenticationFilter loading ...");
 }
 @Override
 public Authentication attemptAuthentication(HttpServletRequest request,      HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
 if (postonly && !request.getMethod().equals(HttpMethod.POST.name())) {
  throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
 }
 //get mobile
 String mobile = obtainMobile(request);
 //assemble token
 MobileLoginAuthenticationToken authRequest = new MobileLoginAuthenticationToken(mobile);

 // Allow subclasses to set the "details" property
 setDetails(request, authRequest);

 return this.getAuthenticationManager().authenticate(authRequest);
 }
 
 private void setDetails(HttpServletRequest request, MobileLoginAuthenticationToken authRequest) {
 authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
 }
 
 private String obtainMobile(HttpServletRequest request) {
 return request.getParameter(mobileParameterName);
 }
 public void setPostonly(boolean postOnly) {
 this.postonly = postOnly;
 }
}

注：attemptAuthentication()方法：

过滤指定的url、httpMethod
获取所需请求参数数据封装生成一个未认证的AuthenticationToken
传递给AuthenticationManager认证

2.2.1.1.自定义认证登录提供者


public class MobileLoginAuthenticationProvider implements AuthenticationProvider {
 private static final Logger logger = LoggerFactory.getLogger(MobileLoginAuthenticationProvider.class.getName());
 @Getter
 @Setter
 private UserDetailsService customUserDetailsService;
 public MobileLoginAuthenticationProvider() {
 logger.info("MobileLoginAuthenticationProvider loading ...");
 }
 
 @Override
 public Authentication authenticate(Authentication authentication) throws AuthenticationException {
 //获取过滤器封装的token信息
 MobileLoginAuthenticationToken authenticationToken = (MobileLoginAuthenticationToken) authentication;
 //获取用户信息（数据库认证）
 UserDetails userDetails = customUserDetailsService.loadUserByUsername((String) authenticationToken.getPrincipal());
 //不通过
 if (userDetails == null) {
  throw new InternalAuthenticationServiceException("Unable to obtain user information");
 }
 //通过
 MobileLoginAuthenticationToken authenticationResult = new MobileLoginAuthenticationToken(userDetails, userDetails.getAuthorities());
 authenticationResult.setDetails(authenticationToken.getDetails());

 return authenticationResult;
 }
 
 @Override
 public boolean supports(Class authentication) {
 return MobileLoginAuthenticationToken.class.isAssignableFrom(authentication);
 }
}

注：authenticate()方法

获取过滤器封装的token信息
调取UserDetailsService获取用户信息（数据库认证）->判断通过与否
通过则封装一个新的AuthenticationToken，并返回

2.2.1.1.自定义认证登录认证配置

@Configuration(SpringBeanNameConstant.DEFAULT_CUSTOM_MOBILE_LOGIN_AUTHENTICATION_SECURITY_CONFIG_BN)
public class MobileLoginAuthenticationSecurityConfig extends SecurityConfigurerAdapter {
 private static final Logger logger = LoggerFactory.getLogger(MobileLoginAuthenticationSecurityConfig.class.getName());
 @Value("${login.mobile.url}")
 private String defaultMobileLoginUrl;
 @Value("${login.mobile.parameter}")
 private String defaultMobileLoginParameter;
 @Value("${login.mobile.httpMethod}")
 private String defaultMobileLoginHttpMethod;
 @Autowired
 private CustomYmlConfig customYmlConfig;
 @Autowired
 private UserDetailsService customUserDetailsService;
 @Autowired
 private AuthenticationSuccessHandler customAuthenticationSuccessHandler;
 @Autowired
 private AuthenticationFailureHandler customAuthenticationFailureHandler;
 public MobileLoginAuthenticationSecurityConfig() {
 logger.info("MobileLoginAuthenticationSecurityConfig loading ...");
 }
 @Override
 public void configure(HttpSecurity http) throws Exception {
 MobilePOJO mobile = customYmlConfig.getLogins().getMobile();
 String url = mobile.getUrl();
 String parameter = mobile.getParameter().getMobile();
 String httpMethod = mobile.getHttpMethod();
 MobileLoginAuthenticationFilter mobileLoginAuthenticationFilter = new MobileLoginAuthenticationFilter(StringUtils.isBlank(url) ? defaultMobileLoginUrl : url,
  StringUtils.isBlank(parameter) ? defaultMobileLoginUrl : parameter, StringUtils.isBlank(httpMethod) ? defaultMobileLoginHttpMethod : httpMethod); mobileLoginAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class)); mobileLoginAuthenticationFilter.setAuthenticationSuccessHandler(customAuthenticationSuccessHandler); mobileLoginAuthenticationFilter.setAuthenticationFailureHandler(customAuthenticationFailureHandler);
 MobileLoginAuthenticationProvider mobileLoginAuthenticationProvider = new MobileLoginAuthenticationProvider(); mobileLoginAuthenticationProvider.setCustomUserDetailsService(customUserDetailsService);
 http.authenticationProvider(mobileLoginAuthenticationProvider)
  .addFilterAfter(mobileLoginAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
 }
}

注：configure()方法

实例化AuthenticationFilter和AuthenticationProvider

将AuthenticationFilter和AuthenticationProvider添加到spring security中。

2.2.2.基于redis自定义验证码校验

2.2.2.1.基于redis自定义验证码过滤器


@Component(SpringBeanNameConstant.DEFAULT_VALIDATE_CODE_FILTER_BN)
public class ValidateCodeFilter extends oncePerRequestFilter implements InitializingBean {
 private static final Logger logger = LoggerFactory.getLogger(ValidateCodeFilter.class.getName());
 @Autowired
 private CustomYmlConfig customYmlConfig;
 @Autowired
 private RedisTemplate redisTemplate;
 
 private AntPathMatcher pathMatcher = new AntPathMatcher();
 public ValidateCodeFilter() {
  logger.info("Loading ValidateCodeFilter...");
 }
 @Override
 protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
  FilterChain filterChain) throws ServletException, IOException {
  String url = customYmlConfig.getLogins().getMobile().getUrl();
  if (pathMatcher.match(url, request.getRequestURI())) {
   String deviceId = request.getHeader("deviceId");
   if (StringUtils.isBlank(deviceId)) {
    throw new CustomException(HttpStatus.NOT_ACCEPTABLE.value(), "Not deviceId in the head of the request");
   }
   String codeParamName = customYmlConfig.getLogins().getMobile().getParameter().getCode();
   String code = request.getParameter(codeParamName);
   if (StringUtils.isBlank(code)) {
    throw new CustomException(HttpStatus.NOT_ACCEPTABLE.value(), "Not code in the parameters of the request");
   }
   String key = SystemConstant.DEFAULT_MOBILE_KEY_PIX + deviceId;
   SmsCodePO smsCodePo = (SmsCodePO) redisTemplate.opsForValue().get(key);
   if (smsCodePo.isExpried()){
    throw new CustomException(HttpStatus.BAD_REQUEST.value(), "The verification code has expired");
   }
   String smsCode = smsCodePo.getCode();
   if (StringUtils.isBlank(smsCode)) {
    throw new CustomException(HttpStatus.BAD_REQUEST.value(), "Verification code does not exist");
   }
   if (StringUtils.equals(code, smsCode)) {
    redisTemplate.delete(key);
    //let it go
    filterChain.doFilter(request, response);
   } else {
    throw new CustomException(HttpStatus.BAD_REQUEST.value(), "Validation code is incorrect");
   }
  }else {
   //let it go
   filterChain.doFilter(request, response);
  }
 }
}

注：doFilterInternal()

自定义验证码过滤校验

2.2.2.2.将自定义验证码过滤器添加到spring security过滤器链

http.addFilterBefore(validateCodeFilter, AbstractPreAuthenticatedProcessingFilter.class)

注：添加到认证预处理过滤器前
