          </dependencies>
      

      二、菜单相关的类

      1、主菜单

      LayUI+Shiro实现动态菜单并记住菜单收展的示例

      /**
       * @author wxhntmy
       */
      @Getter
      @Setter
      public class Menu {
          private String name;
          private String icon;
          private String url;
          private Boolean hidden;
          private List<MenuList> list;
      }
      

      2、子菜单

      LayUI+Shiro实现动态菜单并记住菜单收展的示例

      /**
       * @author wxhntmy
       */
      @Getter
      @Setter
      public class MenuList {
          private String name;
          private String url;
      
          public MenuList(String name, String url) {
              this.name = name;
              this.url = url;
          }
      }
      

      三、Shiro 配置

      1、ShiroConfig

      /**
       * @author wxhntmy
       */
      @Configuration
      public class ShiroConfig {
          /**
           * 配置拦截器
           * <p>
           * 定义拦截URL权限,优先级从上到下 1). anon : 匿名访问,无需登录 2). authc : 登录后才能访问 3). logout: 登出 4).
           * roles : 角色过滤器
           * <p>
           * URL 匹配风格 1). ?:匹配一个字符,如 /admin? 将匹配 /admin1,但不匹配 /admin 或 /admin/; 2).
           * *:匹配零个或多个字符串,如 /admin* 将匹配 /admin 或/admin123,但不匹配 /admin/1; 2).
           * **:匹配路径中的零个或多个路径,如 /admin/** 将匹配 /admin/a 或 /admin/a/b
           * <p>
           * 配置身份验证成功,失败的跳转路径
           */
          @Bean
          public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
              ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();

              filterChainDefinitionMap.put("/user/login", "anon");
      
              // 用户退出
              filterChainDefinitionMap.put("/logout", "logout");
      
      
              // 其他路径均需要身份认证,一般位于最下面,优先级最低
              filterChainDefinitionMap.put("/**", "authc");
      
              shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
              //登录路径
              shiroFilterFactoryBean.setLoginUrl("/login");
              // 主页
              //shiroFilterFactoryBean.setSuccessUrl("/index");
              //验证失败跳转的路径
              shiroFilterFactoryBean.setUnauthorizedUrl("/error");

          }
      
          /**
           * SecurityManager安全管理器;shiro的核心

          public DefaultWebSecurityManager securityManager() {
              DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager(myRealm());
              return defaultWebSecurityManager;
          }
      
          /**
           * 自定义Realm

              return myRealm;
          }
      
          /**
           * 配置加密方式
           * @return
           */
          @Bean
          public MyCredentialsMatcher myCredentialsMatcher() {
              return new MyCredentialsMatcher();
          }
      
          /**
           * 配置Shiro生命周期处理器
           */
          @Bean
          public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
              return new LifecycleBeanPostProcessor();
          }
      
          /**
           * 自动创建代理类,若不添加,Shiro的注解可能不会生效。
           */
          @Bean
          @DependsOn({ "lifecycleBeanPostProcessor" })
          public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator() {

              return new ShiroDialect();
          }
      }
      

      2、自定义shiro密码校验

      /**
       * 自定义shiro密码校验
       * @author wxhntmy
       */
      public class MyCredentialsMatcher implements CredentialsMatcher {
      
          @Resource
          private UserMapper userMapper;
      
          @Override
          public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
      
              UsernamePasswordToken utoken = (UsernamePasswordToken) token;
      
              String password = new String(utoken.getPassword());
              String username = utoken.getUsername();
      
              User user = userMapper.getUserById(username);
      
              return user.getPwd().equals(password);
          }
      }
      

      3、MyRealm

      /**
       * @author wxhntmy
       */
      public class MyRealm extends AuthorizingRealm {
      
          @Resource
          private RoleMapper roleMapper;
          @Resource
          private UserRoleListMapper userRoleListMapper;
      
          //授权
          @Override
          protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
      
              SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
      
              User user = (User) principalCollection.getPrimaryPrincipal();
              if (user == null) {
                  return null;
              }
      
      
              List<UserRoleList> roleLists = userRoleListMapper.getUserRoleByUserId(user.getId());
      
              List<Role> roles = roleMapper.getAllRoles();
      
              if (roleLists != null && !roleLists.isEmpty()) {
                  for (UserRoleList roleList : roleLists) {
                      for (Role role : roles) {
                          if (Objects.equals(roleList.getRole_id(), role.getId())) {
                              authorizationInfo.addRole(role.getRole());
                          }
                      }
                  }
              }
              return authorizationInfo;
          }
      
          //认证
          @Override
          protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
              //获取登录用户账号
              UsernamePasswordToken utoken = (UsernamePasswordToken) authenticationToken;
      
              //获得用户输入的密码
              String password = new String(utoken.getPassword());
              String username = utoken.getUsername();
      
              User user = new User();
      
              user.setId(username);
              user.setPwd(password);
      
              //当前realm对象的唯一名字,调用父类的getName()方法
              String realmName = getName();
      
              // 获取盐值,即用户名
              ByteSource salt = ByteSource.Util.bytes(password);
      
              SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, password, salt, realmName);
      
              return info;
      
          }
      
      }
      

      四、控制类

      1、LoginController

      @RestController
      public class LoginController {
      
          @Resource
          private RoleMapper roleMapper;
          @Resource
          private UserRoleListMapper userRoleListMapper;
          @Resource
          private UserMapper userMapper;
      
          @RequestMapping(value = "/user/login", method = RequestMethod.GET)
          public Msg<String> getUserByName(@RequestParam String user,
                                           @RequestParam String pwd,
                                           @RequestParam String usertype,
                                           @RequestParam String box) {
      
      
              Role role = roleMapper.getRoleByRoleName(usertype);
              User uUser = userMapper.getUserById(user);
              if (uUser == null){
                  return Msg.fail("UserUnexit");
              }
              //登录验证
              UsernamePasswordToken token = new UsernamePasswordToken(user, pwd);
              Subject subject = SecurityUtils.getSubject();
              try {
                  subject.login(token);
              } catch (AuthenticationException e) {
                  return Msg.fail("PasswordError");
              }
              //设置登陆过期时间,单位毫秒,这里设置30分钟
              SecurityUtils.getSubject().getSession().setTimeout(1800000);
              return Msg.ok("Success");
          }
      }
      

      2、PageController

      @Controller
      public class PageController {
      
          @Resource
          private UserMapper userMapper;
      
          @RequestMapping(value = "/login", method = RequestMethod.GET)
          public String Login(){
              return "login";
          }
      
          @RequestMapping(value = "/user/index", method = RequestMethod.GET)
          public String Index(Model model){
      
              User user = (User) SecurityUtils.getSubject().getPrincipal();
      
              User uuser = userMapper.getUserById(user.getId());
      
              if (StringUtils.isEmpty(user)) {
                  return "redirect:/login";
              }
      
              model.addAttribute("user", uuser);
      
              return "index";
          }
      }
      

      3、MenuController

      /**
       * @author wxhntmy
       */
      @RestController
      public class MenuController {
      
          @Resource
          private RoleMapper roleMapper;
          @Resource
          private UserRoleListMapper userRoleListMapper;
      
          //记住用户菜单收展
          private Map<String, Map> menu_map = new HashMap<>();
      
          @RequestMapping(value = "/menu", method = RequestMethod.GET)
          public Msg<List<Menu>> getMenu() {
              User user = (User) SecurityUtils.getSubject().getPrincipal();
      
              List<Menu> list = new ArrayList<>();
      
              if (StringUtils.isEmpty(user)) {
                  return Msg.fail(list, "登录信息已过期!请重新登录!");
              }
      
              //记住收展
              Map<String, Boolean> map_store = new HashMap<>();
      
              if (menu_map.containsKey(user.getId())){
                  map_store = menu_map.get(user.getId());
              }
      
              Map<String, String> map = new HashMap();
              List<UserRoleList> roleLists = userRoleListMapper.getUserRoleByUserId(user.getId());
              for (UserRoleList roleList : roleLists) {
                  Role role = roleMapper.getRoleByRoleId(roleList.getRole_id());
                  map.put(role.getRole(), roleList.getUser_id());
              }
              Menu menu1 = new Menu();
              menu1.setName("首页");
              menu1.setIcon("");
              menu1.setUrl("/user/index");
              menu1.setHidden(false);
      
              List<MenuList> menuLists2 = new ArrayList<>();
              menu1.setList(menuLists2);
              list.add(menu1);
      
      
              if (map.containsKey("student")){
                  Menu menu2 = new Menu();

      2、显示菜单栏

      <ul class="cl">
              <!--顶级分类-->
              <li v-for="vo,index in menu" :class="{hidden:vo.hidden}">
                  <a href="javascript:;" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  :class="{active:vo.active}" @click="onActive(index)">
                      <i class="layui-icon" v-html="vo.icon"></i>
                      <span v-text="vo.name"></span>
                      <i class="layui-icon arrow" v-show="vo.url.length==0"></i> <i v-show="vo.active"
                                                                                            class="layui-icon active"></i>
                  </a>
                  <!--子级分类-->
                  <div v-for="vo2,index2 in vo.list">
                      <a href="javascript:;" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  :class="{active:vo2.active}" @click="onActive(index,index2)"
                         v-text="vo2.name"></a>
                      <i v-show="vo2.active" class="layui-icon active"></i>
                  </div>
              </li>
          </ul>
