这篇文章主要给大家介绍了关于spring security自定义认证登录的相关资料，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧。
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） SecurityContextHolder2）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SpringBootSpring securityRedis2.2.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/** * 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：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/** * 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/** * 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 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
