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:

spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.mode=HTML

 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);

 

四,java代码说明

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
