2,项目功能说明
演示了使用数据库实现的用户RBAC权限管理
三种页面：
无权限限制页面：任何人都可访问
需登录页面：修改密码等：登录才可以访问
有权限限制页面：必须授予相应的角色后才能访问
3,项目结构：如图:
1,pom.xml
<!--security begin--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <!--thymeleaf begin--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!--validation begin--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-validation</artifactId> </dependency> <!--mysql mybatis begin--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.3</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <!-- JSON解析fastjson begin--> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.72</version> </dependency>
2,application.properties
#thymeleaf spring.thymeleaf.cache=false spring.thymeleaf.encoding=UTF-8 spring.thymeleaf.mode=HTML spring.thymeleaf.prefix=classpath:/templates/ spring.thymeleaf.suffix=.html #mysql spring.datasource.url=jdbc:mysql://localhost:3306/security?characterEncoding=utf8&useSSL=false spring.datasource.username=root spring.datasource.password=lhddemo spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver #mybatis mybatis.mapper-locations=classpath:/mapper/*Mapper.xml mybatis.type-aliases-package=com.example.demo.mapper #error server.error.include-stacktrace=always #log logging.level.org.springframework.web=trace
3,数据库：
表结构：
CREATE TABLE `sys_user` ( `userId` int(11) NOT NULL AUTO_INCREMENT COMMENT ‘id‘, `userName` varchar(100) NOT NULL DEFAULT ‘‘ COMMENT ‘用户名‘, `password` varchar(100) NOT NULL DEFAULT ‘‘ COMMENT ‘密码‘, `nickName` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT ‘‘ COMMENT ‘昵称‘, PRIMARY KEY (`userId`), UNIQUE KEY `userName` (`userName`) ) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT=‘用户表‘
添加数据 ：
INSERT INTO `sys_user` (`userId`, `userName`, `password`, `nickName`) VALUES (1, ‘lhd‘, ‘$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq‘, ‘老刘‘), (2, ‘admin‘, ‘$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq‘, ‘管理员‘), (3, ‘merchant‘, ‘$2a$10$yGcOz3ekNI6Ya67tqQueS.raxyTOedGsv5jh2BwtRrI5/K9QEIPGq‘, ‘商户老张‘);
说明：3个密码都是111111，仅供演示使用，大家在生产环境中一定不要这样设置
CREATE TABLE `sys_user_role` ( `urId` int(11) NOT NULL AUTO_INCREMENT COMMENT ‘id‘, `userId` int(11) NOT NULL DEFAULT ‘0‘ COMMENT ‘用户id‘, `roleName` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT ‘‘ COMMENT ‘角色id‘, PRIMARY KEY (`urId`), UNIQUE KEY `userId` (`userId`,`roleName`) ) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT=‘用户角色关联表‘
插入数据:
INSERT INTO `sys_user_role` (`urId`, `userId`, `roleName`) VALUES (1, 2, ‘ADMIN‘), (2, 3, ‘MERCHANT‘);
1，WebSecurityConfig.java
@Configuration @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { private final static BCryptPasswordEncoder ENCODER = new BCryptPasswordEncoder(); @Resource private UserLoginFailureHandler userLoginFailureHandler;//登录失败的处理类 @Resource private UserLoginSuccessHandler userLoginSuccessHandler;//登录成功的处理类 @Resource private UserLogoutSuccessHandler userLogoutSuccessHandler;//退出成功的处理类 @Resource private UserAccessDeniedHandler userAccessDeniedHandler;//无权访问的处理类 @Resource private SecUserDetailService secUserDetailService; //用户信息类，用来得到UserDetails //指定加密的方式，避免出现:There is no PasswordEncoder mapped for the id "null" @Bean public PasswordEncoder passwordEncoder(){//密码加密类 return new BCryptPasswordEncoder(); } @Override protected void configure(HttpSecurity http) throws Exception { //static http.authorizeRequests() .antMatchers("/css/**","/js/**","/img/**")//静态资源等不需要验证 .permitAll(); //permitall http.authorizeRequests() .antMatchers("/home/**")//permitall .permitAll(); //login http.formLogin() .loginPage("/login/login") .loginProcessingUrl("/login/logined")//发送Ajax请求的路径 .usernameParameter("username")//请求验证参数 .passwordParameter("password")//请求验证参数 .failureHandler(userLoginFailureHandler)//验证失败处理 .successHandler(userLoginSuccessHandler)//验证成功处理 .permitAll(); //登录页面用户任意访问 //logout http.logout() .logoutUrl("/login/logout") .logoutSuccessUrl("/login/logout") .logoutSuccessHandler(userLogoutSuccessHandler)//登出处理 .deleteCookies("JSESSIONID") .clearAuthentication(true) .invalidateHttpSession(true) .permitAll(); //有角色的用户才能访问 http.authorizeRequests() .antMatchers("/admin/**").hasRole("ADMIN") .antMatchers("/merchant/**").hasAnyRole("MERCHANT","ADMIN"); //其他任何请求,登录后可以访问 http.authorizeRequests().anyRequest().authenticated(); //accessdenied http.exceptionHandling().accessDeniedHandler(userAccessDeniedHandler);//无权限时的处理 //user detail http.userDetailsService(secUserDetailService); //rememberme //图形验证码 //http.csrf().disable(); } @Resource public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(secUserDetailService).passwordEncoder(new PasswordEncoder() { @Override public String encode(CharSequence charSequence) { return ENCODER.encode(charSequence); } //密码匹配，看输入的密码经过加密与数据库中存放的是否一样 @Override public boolean matches(CharSequence charSequence, String s) { return ENCODER.matches(charSequence,s); } }); } }
2,SecUser.java
public class SecUser extends User { //用户id private int userid; //用户昵称 private String nickname; public SecUser(String username, String password, Collection<? extends GrantedAuthority> authorities) { super(username, password, authorities); } public SecUser(String username, String password, boolean enabled, boolean accountNonExpired, boolean credentialsNonExpired, boolean accountNonLocked, Collection<? extends GrantedAuthority> authorities) { super(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities); } public String getNickname() { return nickname; } public void setNickname(String nickname) { this.nickname = nickname; } public int getUserid() { return userid; } public void setUserid(int userid) { this.userid = userid; } }
spring security中User类的子类，增加了用户id和昵称，
需要保存到session中的信息，在这里扩展
目的是避免在每个页面上显示用户信息需要查数据库
3,SecUserDetailService.java
/** * Created by liuhongdi on 2020/07/09. */ @Component("SecUserDetailService") public class SecUserDetailService implements UserDetailsService{ @Resource private SysUserService sysUserService; @Override public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException { //查库 SysUser oneUser = sysUserService.getOneUserByUsername(s);//数据库查询 看用户是否存在 String encodedPassword = oneUser.getPassword(); Collection<GrantedAuthority> collection = new ArrayList<>();//权限集合 //用户权限：需要加 ROLE_ List<String> roles = oneUser.getRoles(); //System.out.println(roles); for (String roleone : roles) { GrantedAuthority grantedAuthority = new SimpleGrantedAuthority("ROLE_"+roleone); collection.add(grantedAuthority); } //增加用户的userid,nickname SecUser user = new SecUser(s,encodedPassword,collection); user.setUserid(oneUser.getUserId()); user.setNickname(oneUser.getNickName()); return user; } }
4,UserAccessDeniedHandler.java
@Component("UserAccessDeniedHandler")
public class UserAccessDeniedHandler implements AccessDeniedHandler {
@Override
public void handle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,
AccessDeniedException e) throws IOException, ServletException {
boolean isAjax = ServletUtil.isAjax();
//System.out.println("isajax:"+isAjax);
if (isAjax == true) {
ServletUtil.printRestResult(RestResult.error(ResponseCode.ACCESS_DENIED));
} else {
ServletUtil.printString(ResponseCode.ACCESS_DENIED.getMsg());
}
}
}
5,UserLoginFailureHandler.java
@Component("UserLoginFailureHandler")
public class UserLoginFailureHandler extends SimpleUrlAuthenticationFailureHandler {
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
AuthenticationException exception) throws IOException, ServletException {
//System.out.println("UserLoginFailureHandler");
ServletUtil.printRestResult(RestResult.error(ResponseCode.LOGIN_FAIL));
}
}
6,UserLoginSuccessHandler.java
@Component("UserLoginSuccessHandler")
public class UserLoginSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
//System.out.println("UserLoginSuccessHandler");
ServletUtil.printRestResult(RestResult.success(0,"登录成功"));
}
}
7,UserLogoutSuccessHandler.java
@Component("UserLogoutSuccessHandler")
public class UserLogoutSuccessHandler implements LogoutSuccessHandler{
@Override
public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
httpServletRequest.getSession().invalidate();
ServletUtil.printRestResult(RestResult.success(0,"退出成功"));
}
}
8,WebInterceptor.java
@Component public class WebInterceptor extends HandlerInterceptorAdapter { //如果view不为空，把登录信息传递给模板 @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) { if (modelAndView != null) { ModelMap modelMap = modelAndView.getModelMap(); SecUser currentUser = SessionUtil.getCurrentUser(); if (currentUser != null) { modelMap.addAttribute("is_login","1"); modelMap.addAttribute("login_username",currentUser.getNickname()); } else { modelMap.addAttribute("is_login","0"); modelMap.addAttribute("login_username",""); } } } }
负责把传递页面公共部分显示的数据到模板
9,login.html
<!DOCTYPE html> <html> <head> <meta content="text/html;charset=UTF-8"/> <title>登录页面</title> <script type="text/javascript" language="JavaScript" src="/js/jquery-1.6.2.min.js"></script> <style type="text/css"> body { padding-top: 50px; } .starter-template { padding: 40px 15px; text-align: center; } </style> <!-- CSRF --> <meta name="_csrf" th:content="${_csrf.token}"/> <!-- default header name is X-CSRF-TOKEN --> <meta name="_csrf_header" th:content="${_csrf.headerName}"/> </head> <body> <nav class="navbar navbar-inverse navbar-fixed-top"> <div class="container"> <div id="navbar" class="collapse navbar-collapse"> <ul class="nav navbar-nav"> <li><a href="/home/home"> 首页 </a></li> </ul> </div><!--/.nav-collapse --> </div> </nav> <div class="container"> <div class="starter-template"> <h2>使用账号密码登录</h2> <div class="form-group"> <label for="username">账号</label> <input type="text" class="form-control" id="username" name="username" value="" placeholder="账号" /> </div> <div class="form-group"> <label for="password">密码</label> <input type="password" class="form-control" id="password" name="password" placeholder="密码" /> </div> <button name="formsubmit" value="登录" onclick="go_login()" >登录</button> </div> </div> <script> function go_login(){ if ($("#username").val() == "") { alert(‘用户名不可为空‘); $("#username").focus(); return false; } if ($("#password").val() == "") { alert(‘密码不可为空‘); $("#password").focus(); return false; } var postdata = { username:$("#username").val(), password:$("#password").val(), } var csrfToken = $("meta[name=‘_csrf‘]").attr("content"); var csrfHeader = $("meta[name=‘_csrf_header‘]").attr("content"); $.ajax({ type:"POST", //type:"GET", url:"/login/logined", data:postdata, //返回数据的格式 datatype: "json",//"xml", "html", "script", "json", "jsonp", "text". beforeSend: function(request) { request.setRequestHeader(csrfHeader, csrfToken); // 添加 CSRF Token }, success:function(data){ if (data.code == 0) { alert(‘login success:‘+data.msg); window.location.href="/home/home"; } else { alert("failed:"+data.msg); } }, //调用执行后调用的函数 complete: function(XMLHttpRequest, textStatus){ }, //调用出错执行的函数 error: function(){ //请求出错处理 alert(‘error‘); } }); } </script> </body> </html>
10,页面上用到的其他代码，可以移步github.com上查看
1,访问首页:
http://127.0.0.1:8080/home/home
未登录时：
2，以普通用户lhd登录:
访问:管理员首页/商户首页，都会得到提示
无权访问
访问修改密码 页面，可以访问
3,以merchant用户登录：
role是MERCHANT
访问:管理员首页，提示:
无权访问
访问商户首页:可以访问
访问修改密码 页面，可以访问
4，以admin用户登录:
role是ADMIN
访问管理员首页:可以访问
访问商户首页:可以访问
访问修改密码 页面，可以访问
