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
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 /** * 手机登录Token * * @author : CatalpaFlat */ 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<? extends GrantedAuthority> 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
2.2.1.1.自定义认证登录过滤器 /** * 手机短信登录过滤器 * * @author : CatalpaFlat */ 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); } /** * 设置身份认证的详情信息 */ private void setDetails(HttpServletRequest request,MobileLoginAuthenticationToken authRequest) { authRequest.setDetails(authenticationDetailsSource.buildDetails(request)); } /** * 获取手机号 */ private String obtainMobile(HttpServletRequest request) { return request.getParameter(mobileParameterName); } public void setPostOnly(boolean postOnly) { this.postOnly = postOnly; } } 注:attemptAuthentication()方法:
2.2.1.1.自定义认证登录提供者 /** * 手机短信登录认证提供者 * * @author : CatalpaFlat */ 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 ..."); } /** * 认证 */ @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; } /** * 根据token类型,来判断使用哪个Provider */ @Override public boolean supports(Class<?> authentication) { return MobileLoginAuthenticationToken.class.isAssignableFrom(authentication); } } 注:authenticate()方法
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<DefaultSecurityFilterChain,HttpSecurity> { 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 /** * 验证码过滤器 * * @author : CatalpaFlat */ @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<Object,Object> redisTemplate; /** * 验证请求url与配置的url是否匹配的工具类 */ 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 3.测试效果 最后附上源码地址:https://gitee.com/CatalpaFlat/springSecurity.git (本地下载) 总结 以上就是这篇文章的全部内容了,希望本文的内容对大家的学习或者工作具有一定的参考学习价值,如果有疑问大家可以留言交流,谢谢大家对编程小技巧的支持。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
