一、前言

本篇文章将讲述Spring Security自定义登录认证校验用户名、密码,自定义密码加密方式,以及在前后端分离的情况下认证失败或成功处理返回json格式数据

温馨小提示:Spring Security中有默认的密码加密方式以及登录用户认证校验,但小编这里选择自定义是为了方便以后业务扩展,比如系统默认带一个超级管理员,当认证时识别到是超级管理员账号登录访问时给它赋予最高权限,可以访问系统所有api接口,或在登录认证成功后存入token以便用户访问系统其它接口时通过token认证用户权限等

二、Spring Security 自定义登录认证处理

基本环境
  1. spring-boot 2.1.8
  2. mybatis-plus 2.2.0
  3. mysql
  4. maven项目

数据库用户信息表t_sys_user
在这里插入图片描述

案例中关于对该t_sys_user用户表相关的增删改查代码就不贴出来了,如有需要可参考文末提供的案例demo源码

1、Security 核心配置类

配置用户密码校验过滤器

@Configuration  @EnableWebSecurity  @EnableGlobalMethodSecurity(prePostEnabled = true)  public class SecurityConfig extends WebSecurityConfigurerAdapter {        /**       * 用户密码校验过滤器       */      private final AdminAuthenticationProcessingFilter adminAuthenticationProcessingFilter;        public SecurityConfig(AdminAuthenticationProcessingFilter adminAuthenticationProcessingFilter) {          this.adminAuthenticationProcessingFilter = adminAuthenticationProcessingFilter;      }        /**       * 权限配置       * @param http       * @throws Exception       */      @Override      protected void configure(HttpSecurity http) throws Exception {          ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry registry = http.antMatcher("/**").authorizeRequests();            // 禁用CSRF 开启跨域          http.csrf().disable().cors();            // 登录处理 - 前后端一体的情况下  //        registry.and().formLogin().loginPage("/login").defaultSuccessUrl("/").permitAll()  //                // 自定义登陆用户名和密码属性名,默认为 username和password  //                .usernameParameter("username").passwordParameter("password")  //                // 异常处理  //                .failureUrl("/login/error").permitAll()  //                // 退出登录  //                .and().logout().permitAll();            // 标识只能在 服务器本地ip[127.0.0.1或localhost] 访问`/home`接口,其他ip地址无法访问          registry.antMatchers("/home").hasIpAddress("127.0.0.1");          // 允许匿名的url - 可理解为放行接口 - 多个接口使用,分割          registry.antMatchers("/login", "/index").permitAll();          // OPTIONS(选项):查找适用于一个特定网址资源的通讯选择。 在不需执行具体的涉及数据传输的动作情况下, 允许客户端来确定与资源相关的选项以及 / 或者要求, 或是一个服务器的性能          registry.antMatchers(HttpMethod.OPTIONS, "/**").denyAll();          // 自动登录 - cookie储存方式          registry.and().rememberMe();          // 其余所有请求都需要认证          registry.anyRequest().authenticated();          // 防止iframe 造成跨域          registry.and().headers().frameOptions().disable();            // 自定义过滤器认证用户名密码          http.addFilterAt(adminAuthenticationProcessingFilter, UsernamePasswordAuthenticationFilter.class);      }  }

2、自定义用户密码校验过滤器

@Slf4j  @Component  public class AdminAuthenticationProcessingFilter extends AbstractAuthenticationProcessingFilter {        /**       * @param authenticationManager:             认证管理器       * @param adminAuthenticationSuccessHandler: 认证成功处理       * @param adminAuthenticationFailureHandler: 认证失败处理       */      public AdminAuthenticationProcessingFilter(CusAuthenticationManager authenticationManager, AdminAuthenticationSuccessHandler adminAuthenticationSuccessHandler, AdminAuthenticationFailureHandler adminAuthenticationFailureHandler) {          super(new AntPathRequestMatcher("/login", "POST"));          this.setAuthenticationManager(authenticationManager);          this.setAuthenticationSuccessHandler(adminAuthenticationSuccessHandler);          this.setAuthenticationFailureHandler(adminAuthenticationFailureHandler);      }        @Override      public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {          if (request.getContentType() == null || !request.getContentType().contains(Constants.REQUEST_HEADERS_CONTENT_TYPE)) {              throw new AuthenticationServiceException("请求头类型不支持: " + request.getContentType());          }            UsernamePasswordAuthenticationToken authRequest;          try {              MultiReadHttpServletRequest wrappedRequest = new MultiReadHttpServletRequest(request);              // 将前端传递的数据转换成jsonBean数据格式              User user = JSONObject.parseObject(wrappedRequest.getBodyJsonStrByJson(wrappedRequest), User.class);              authRequest = new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword(), null);              authRequest.setDetails(authenticationDetailsSource.buildDetails(wrappedRequest));          } catch (Exception e) {              throw new AuthenticationServiceException(e.getMessage());          }          return this.getAuthenticationManager().authenticate(authRequest);      }  }

3、自定义认证管理器

@Component  public class CusAuthenticationManager implements AuthenticationManager {        private final AdminAuthenticationProvider adminAuthenticationProvider;        public CusAuthenticationManager(AdminAuthenticationProvider adminAuthenticationProvider) {          this.adminAuthenticationProvider = adminAuthenticationProvider;      }        @Override      public Authentication authenticate(Authentication authentication) throws AuthenticationException {          Authentication result = adminAuthenticationProvider.authenticate(authentication);          if (Objects.nonNull(result)) {              return result;          }          throw new ProviderNotFoundException("Authentication failed!");      }  }

4、自定义认证处理

这里的密码加密验证工具类PasswordUtils可在文末源码中查看

@Component  public class AdminAuthenticationProvider implements AuthenticationProvider {        @Autowired      UserDetailsServiceImpl userDetailsService;      @Autowired      private UserMapper userMapper;        @Override      public Authentication authenticate(Authentication authentication) throws AuthenticationException {          // 获取前端表单中输入后返回的用户名、密码          String userName = (String) authentication.getPrincipal();          String password = (String) authentication.getCredentials();            SecurityUser userInfo = (SecurityUser) userDetailsService.loadUserByUsername(userName);            boolean isValid = PasswordUtils.isValidPassword(password, userInfo.getPassword(), userInfo.getCurrentUserInfo().getSalt());          // 验证密码          if (!isValid) {              throw new BadCredentialsException("密码错误!");          }            // 前后端分离情况下 处理逻辑...          // 更新登录令牌 - 之后访问系统其它接口直接通过token认证用户权限...          String token = PasswordUtils.encodePassword(System.currentTimeMillis() + userInfo.getCurrentUserInfo().getSalt(), userInfo.getCurrentUserInfo().getSalt());          User user = userMapper.selectById(userInfo.getCurrentUserInfo().getId());          user.setToken(token);          userMapper.updateById(user);          userInfo.getCurrentUserInfo().setToken(token);          return new UsernamePasswordAuthenticationToken(userInfo, password, userInfo.getAuthorities());      }        @Override      public boolean supports(Class<?> aClass) {          return true;      }  }

其中小编自定义了一个UserDetailsServiceImpl类去实现UserDetailsService类 -> 用于认证用户详情
和自定义一个SecurityUser类实现UserDetails类 -> 安全认证用户详情信息

@Service("userDetailsService")  public class UserDetailsServiceImpl implements UserDetailsService {        @Autowired      private UserMapper userMapper;        /***       * 根据账号获取用户信息       * @param username:       * @return: org.springframework.security.core.userdetails.UserDetails       */      @Override      public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {          // 从数据库中取出用户信息          List<User> userList = userMapper.selectList(new EntityWrapper<User>().eq("username", username));          User user;          // 判断用户是否存在          if (!CollectionUtils.isEmpty(userList)){              user = userList.get(0);          } else {              throw new UsernameNotFoundException("用户名不存在!");          }          // 返回UserDetails实现类          return new SecurityUser(user);      }  }

安全认证用户详情信息

@Data  @Slf4j  public class SecurityUser implements UserDetails {      /**       * 当前登录用户       */      private transient User currentUserInfo;        public SecurityUser() {      }        public SecurityUser(User user) {          if (user != null) {              this.currentUserInfo = user;          }      }        @Override      public Collection<? extends GrantedAuthority> getAuthorities() {          Collection<GrantedAuthority> authorities = new ArrayList<>();          SimpleGrantedAuthority authority = new SimpleGrantedAuthority("admin");          authorities.add(authority);          return authorities;      }        @Override      public String getPassword() {          return currentUserInfo.getPassword();      }        @Override      public String getUsername() {          return currentUserInfo.getUsername();      }        @Override      public boolean isAccountNonExpired() {          return true;      }        @Override      public boolean isAccountNonLocked() {          return true;      }        @Override      public boolean isCredentialsNonExpired() {          return true;      }        @Override      public boolean isEnabled() {          return true;      }  }

5、自定义认证成功或失败处理方式

  1. 认证成功处理类实现AuthenticationSuccessHandler类重写onAuthenticationSuccess方法
  2. 认证失败处理类实现AuthenticationFailureHandler类重写onAuthenticationFailure方法

在前后端分离情况下小编认证成功和失败都返回json数据格式

认证成功后这里小编只返回了一个token给前端,其它信息可根据个人业务实际处理

@Component  public class AdminAuthenticationSuccessHandler implements AuthenticationSuccessHandler {      @Override      public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse response, Authentication auth) throws IOException, ServletException {          User user = new User();          SecurityUser securityUser = ((SecurityUser) auth.getPrincipal());          user.setToken(securityUser.getCurrentUserInfo().getToken());          ResponseUtils.out(response, ApiResult.ok("登录成功!", user));      }  }

认证失败捕捉异常自定义错误信息返回给前端

@Slf4j  @Component  public class AdminAuthenticationFailureHandler implements AuthenticationFailureHandler {      @Override      public void onAuthenticationFailure(HttpServletRequest httpServletRequest, HttpServletResponse response, AuthenticationException e) throws IOException, ServletException {          ApiResult result;          if (e instanceof UsernameNotFoundException || e instanceof BadCredentialsException) {              result = ApiResult.fail(e.getMessage());          } else if (e instanceof LockedException) {              result = ApiResult.fail("账户被锁定,请联系管理员!");          } else if (e instanceof CredentialsExpiredException) {              result = ApiResult.fail("证书过期,请联系管理员!");          } else if (e instanceof AccountExpiredException) {              result = ApiResult.fail("账户过期,请联系管理员!");          } else if (e instanceof DisabledException) {              result = ApiResult.fail("账户被禁用,请联系管理员!");          } else {              log.error("登录失败:", e);              result = ApiResult.fail("登录失败!");          }          ResponseUtils.out(response, result);      }  }
温馨小提示:

前后端一体的情况下可通过在Spring Security核心配置类中配置异常处理接口然后通过如下方式获取异常信息

AuthenticationException e = (AuthenticationException) request.getSession().getAttribute("SPRING_SECURITY_LAST_EXCEPTION");  System.out.println(e.getMessage());

三、前端页面

这里2个简单的html页面模拟前后端分离情况下登陆处理场景

1、登陆页

login.html

<!DOCTYPE html>  <html lang="en">  <head>      <meta charset="UTF-8">      <title>Login</title>  </head>  <body>  <h1>Spring Security</h1>  <form method="post" action="" onsubmit="return false">      <div>          用户名:<input type="text" name="username" id="username">      </div>      <div>          密码:<input type="password" name="password" id="password">      </div>      <div>  <!--        <label><input type="checkbox" name="remember-me" id="remember-me"/>自动登录</label>-->          <button onclick="login()">登陆</button>      </div>  </form>  </body>  <script src="http://libs.baidu.com/jquery/1.9.0/jquery.js" type="text/javascript"></script>  <script type="text/javascript">      function login() {          var username = document.getElementById("username").value;          var password = document.getElementById("password").value;          // var rememberMe = document.getElementById("remember-me").value;          $.ajax({              async: false,              type: "POST",              dataType: "json",              url: '/login',              contentType: "application/json",              data: JSON.stringify({                  "username": username,                  "password": password                  // "remember-me": rememberMe              }),              success: function (result) {                  console.log(result)                  if (result.code == 200) {                      alert("登陆成功");                      window.location.href = "../home.html";                  } else {                      alert(result.message)                  }              }          });      }  </script>  </html>
2、首页

home.html

<!DOCTYPE html>  <html lang="en">  <head>      <meta charset="UTF-8">      <title>Title</title>  </head>  <body>  <h3>您好,登陆成功</h3>  <button onclick="window.location.href='/logout'">退出登录</button>  </body>  </html>

四、测试接口

@Slf4j  @RestController  public class IndexController {        @GetMapping("/")      public ModelAndView showHome() {          return new ModelAndView("home.html");      }        @GetMapping("/index")      public String index() {          return "Hello World ~";      }        @GetMapping("/login")      public ModelAndView login() {          return new ModelAndView("login.html");      }        @GetMapping("/home")      public String home() {          String name = SecurityContextHolder.getContext().getAuthentication().getName();          log.info("登陆人:" + name);          return "Hello~ " + name;      }        @GetMapping(value ="/admin")      // 访问路径`/admin` 具有`crud`权限      @PreAuthorize("hasPermission('/admin','crud')")      public String admin() {          return "Hello~ 管理员";      }        @GetMapping("/test")  //    @PreAuthorize("hasPermission('/test','t')")      public String test() {          return "Hello~ 测试权限访问接口";      }        /**       * 登录异常处理 - 前后端一体的情况下       * @param request       * @param response       */      @RequestMapping("/login/error")      public void loginError(HttpServletRequest request, HttpServletResponse response) {          AuthenticationException e = (AuthenticationException) request.getSession().getAttribute("SPRING_SECURITY_LAST_EXCEPTION");          log.error(e.getMessage());          ResponseUtils.out(response, ApiResult.fail(e.getMessage()));      }  }

五、测试访问效果

数据库账号:admin 密码:123456

1. 输入错误用户名提示该用户不存在

在这里插入图片描述

2. 输入错误密码提示密码错误

在这里插入图片描述

3. 输入正确用户名和账号,提示登陆成功,然后跳转到首页

在这里插入图片描述
在这里插入图片描述

登陆成功后即可正常访问其他接口,如果是未登录情况下将访问不了

在这里插入图片描述

温馨小提示:这里在未登录时或访问未授权的接口时,后端暂时没有做处理,相关案例将会放在后面的权限控制案例教程中讲解

在这里插入图片描述

六、总结

  1. Spring Security核心配置类中设置自定义的用户密码校验过滤器(AdminAuthenticationProcessingFilter)
  2. 在自定义的用户密码校验过滤器中配置认证管理器(CusAuthenticationManager)认证成功处理(AdminAuthenticationSuccessHandler)认证失败处理(AdminAuthenticationFailureHandler)
  3. 在自定义的认证管理器中配置自定义的认证处理(AdminAuthenticationProvider)
  4. 然后就是在认证处理中实现自己的相应业务逻辑等
