SpringBoot详解shiro过滤器与权限控制

 @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWEBSecurityManager defaultWebSecurityManager) {
        // 创建ShiroFilterFactoryBean
        ShiroFilterFactoryBean filterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        filterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        //配置受限资源,index是受限资源，authc
        Map<String, String> map = new HashMap<String, String>();
        // 
        Map<String, Filter> filters = shiroFilterFactoryBean.getFilters();
        //根据上面列表中的过滤器的名称配置
        filters.put("roles", new MyAuthorizationFilter());
        return shiroFilterFactoryBean;
    }

// 示例
    //拥有一个角色就可以访问
    @RequiresRoles(value={"ADMIN","USER"},logical = Logical.OR)
    //拥有所有权限才可以访问
    @RequiresPermissions(value={"sys:user:info","sys:role:info"},logical = Logical.AND)

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        // 获取用户
        User user = (User) principalCollection.getPrimaryPrincipal();
        Integer userId =user.getId();
        // 这里可以进行授权和处理
        Set<String> rolesSet = new HashSet<>();
        Set<String> permsSet = new HashSet<>();
        // 获取当前用户对应的权限(这里根据业务自行查询)
        List<Role> roleList = roleMapper.selectRoleByUserId( userId );
        for (Role role:roleList) {
            rolesSet.add( role.getCode() );
            List<Menu> menuList = menuMapper.selectMenuByRoleId( role.getId() );
            for (Menu menu :menuList) {
                permsSet.add( menu.getResources() );
            }
        }
        //将查到的权限和角色分别传入authorizationInfo中
        authorizationInfo.setStringPermissions(permsSet);
        authorizationInfo.setRoles(rolesSet);
        log.info("--------------- 赋予角色和权限成功！ ---------------");
        return authorizationInfo;
    }
