一、自定义认证逻辑
二、自定义过滤器
生成验证码工具
<dependency> <groupId>com.github.penggle</groupId> <artifactId>kaptcha</artifactId> <version>2.3.2</version> </dependency>
添加Kaptcha配置
@Configuration public class KaptchaConfig { @Bean Producer kaptcha() { Properties properties = new Properties(); properties.setProperty("kaptcha.image.width", "150"); properties.setProperty("kaptcha.image.height", "50"); properties.setProperty("kaptcha.textproducer.char.string", "0123456789"); properties.setProperty("kaptcha.textproducer.char.length", "4"); Config config = new Config(properties); DefaultKaptcha defaultKaptcha = new DefaultKaptcha(); defaultKaptcha.setConfig(config); return defaultKaptcha; } }
生成验证码文本,放入HttpSession中
根据验证码文本生成图片 通过IO流写出到前端。
@RestController public class LoginController { @Autowired Producer producer; @GetMapping("/vc.jpg") public void getVerifyCode(HttpServletResponse resp, HttpSession session) throws IOException { resp.setContentType("image/jpeg"); String text = producer.createText(); session.setAttribute("kaptcha", text); BufferedImage image = producer.createImage(text); try(ServletOutputStream out = resp.getOutputStream()) { ImageIO.write(image, "jpg", out); } } @RequestMapping("/index") public String index() { return "login success"; } @RequestMapping("/hello") public String hello() { return "hello spring security"; } }
form表单
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>登录</title> <link href="//maxcdn.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" rel="external nofollow" rel="stylesheet" id="bootstrap-css"> <script src="//maxcdn.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script> <script src="//cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> </head> <style> #login .container #login-row #login-column #login-box { border: 1px solid #9C9C9C; background-color: #EAEAEA; } </style> <body> <div id="login"> <div class="container"> <div id="login-row" class="row justify-content-center align-items-center"> <div id="login-column" class="col-md-6"> <div id="login-box" class="col-md-12"> <form id="login-form" class="form" action="/doLogin" method="post"> <h4 class="text-center text-info">登录</h4> <div th:text="${SPRING_SECURITY_LAST_EXCEPTION}"></div> <div class="form-group"> <label for="username" class="text-info">用户名:</label><br> <input type="text" name="uname" id="username" class="form-control"> </div> <div class="form-group"> <label for="password" class="text-info">密码:</label><br> <input type="text" name="passwd" id="password" class="form-control"> </div> <div class="form-group"> <label for="kaptcha" class="text-info">验证码:</label><br> <input type="text" name="kaptcha" id="kaptcha" class="form-control"> <img src="/vc.jpg" alt=""> </div> <div class="form-group"> <input type="submit" name="submit" class="btn btn-info btn-md" value="登录"> </div> </form> </div> </div> </div> </div> </div> </body>
验证码图片地址为我们在Controller中定义的验证码接口地址。
身份认证是AuthenticationProvider的authenticate方法完成,因此验证码可以在此之前完成:
public class KaptchaAuthenticationProvider extends DaoAuthenticationProvider { @Override public Authentication authenticate(Authentication authentication) throws AuthenticationException { HttpServletRequest req = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest(); String kaptcha = req.getParameter("kaptcha"); String sessionKaptcha = (String) req.getSession().getAttribute("kaptcha"); if (kaptcha != null && sessionKaptcha != null && kaptcha.equalsIgnoreCase(sessionKaptcha)) { return super.authenticate(authentication); } throw new AuthenticationServiceException("验证码输入错误"); } }
配置AuthenticationManager:
@Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter { @Bean AuthenticationProvider kaptchaAuthenticationProvider() { InMemoryUserDetailsManager users = new InMemoryUserDetailsManager(User.builder() .username("xiepanapn").password("{noop}123").roles("admin").build()); KaptchaAuthenticationProvider provider = new KaptchaAuthenticationProvider(); provider.setUserDetailsService(users); return provider; } @Override @Bean public AuthenticationManager authenticationManagerBean() throws Exception { ProviderManager manager = new ProviderManager(kaptchaAuthenticationProvider()); return manager; } @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/vc.jpg").permitAll() .anyRequest().authenticated() .and() .formLogin() .loginPage("/mylogin.html") .loginProcessingUrl("/doLogin") .defaultSuccessUrl("/index.html") .failureForwardUrl("/mylogin.html") .usernameParameter("uname") .passwordParameter("passwd") .permitAll() .and() .csrf().disable(); } }
配置UserDetailsService提供的数据源
提供AuthenticationProvider实例并配置UserDetailsService
重写authenticationManagerBean方法提供一个自己的ProviderManager并自定义AuthenticationManager实例。
LoginFilter继承UsernamePasswordAuthenticationFilter 重写attemptAuthentication方法:
public class LoginFilter extends UsernamePasswordAuthenticationFilter { @Override public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException { if (!request.getMethod().equals("POST")) { throw new AuthenticationServiceException( "Authentication method not supported: " + request.getMethod()); } String kaptcha = request.getParameter("kaptcha"); String sessionKaptcha = (String) request.getSession().getAttribute("kaptcha"); if (!StringUtils.isEmpty(kaptcha) && !StringUtils.isEmpty(sessionKaptcha) && kaptcha.equalsIgnoreCase(sessionKaptcha)) { return super.attemptAuthentication(request, response); } throw new AuthenticationServiceException("验证码输入错误"); } }
在SecurityConfig中配置LoginFilter
@Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication() .withUser("javaboy") .password("{noop}123") .roles("admin"); } @Override @Bean public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); } @Bean LoginFilter loginFilter() throws Exception { LoginFilter loginFilter = new LoginFilter(); loginFilter.setFilterProcessesUrl("/doLogin"); loginFilter.setAuthenticationManager(authenticationManagerBean()); loginFilter.setAuthenticationSuccessHandler(new SimpleUrlAuthenticationSuccessHandler("/hello")); loginFilter.setAuthenticationFailureHandler(new SimpleUrlAuthenticationFailureHandler("/mylogin.html")); return loginFilter; } @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/vc.jpg").permitAll() .anyRequest().authenticated() .and() .formLogin() .loginPage("/mylogin.html") .permitAll() .and() .csrf().disable(); http.addFilterAt(loginFilter(), UsernamePasswordAuthenticationFilter.class); } }
显然第二种比较简单
