spring security oauth2 动态切换角色或者岗位，更新redis缓存

1、切换角色或者岗位后更新缓存token，获取token，并更新token，特别要注意token中的内容

accessToken.getAdditionalInformation().put(SecurityConstants.DETAILS_POST_ID,postId);

 String key = authenticationKeyGenerator.extractKey(originalOAuth2Authentication);
                    byte[] serializedKey =  serializationStrategy.serialize(CacheConstants.PROJECT_OAUTH_ACCESS+"auth_to_access:" + key);
                    byte[] bytes = null;
                    RedisConnection conn = redisConnectionFactory.getConnection();
                    try {
                        bytes = conn.get(serializedKey);
                    } finally {
                        conn.close();
                    }
                    OAuth2AccessToken accessToken =serializationStrategy.deserialize(bytes,OAuth2AccessToken.class);
                    accessToken.getAdditionalInformation().put(SecurityConstants.DETAILS_POST_ID,postId);
                        tokenStore.storeAccessToken(accessToken,oauth2Authentication);

切换用户后，进行数据的更新。

 SysUser user = userService.selectUserByUserName(SecurityUtils.getUser().getUsername());
        Authentication authentication=SecurityContextHolder.getContext().getAuthentication();
        List postList= postService.selectPostsByUserName(user.getUserName());
        user.setPosts(postList);
        user.setPostId(postId);
        //角色集合
        //先查询对应岗位的角色ID
        Set roles=postService.selectRoleIdsByPostId(postId);
        if(roles.size()<1){
            return R.failed("该岗位无权访问系统");
        }
        user.setRoleIds(roles.toArray(new Integer[roles.size()]));
        // 角色集合
        //Set roles = permissionService.getRolePermission(sysUser.getUserId());
        // 权限集合
        //Set permissions = permissionService.getMenuPermission(sysUser.getUserId());
        Set permissions = permissionService.getMenuPermissionByRoles(user.getUserId(),roles);
        Set dbAuthsSet = new HashSet<>();
        if (ArrayUtil.isNotEmpty(roles)) {
            // 获取角色
            roles.forEach(role -> dbAuthsSet.add(SecurityConstants.ROLE + role));
            // 获取资源
            dbAuthsSet.addAll(permissions);

        }
        Collection authorities = AuthorityUtils
                .createAuthorityList(dbAuthsSet.toArray(new String[0]));

//        // 构造security用户
        UserDetails userDetails =new ItduUser(user.getUserId(),postId, user.getDeptId(), user.getRoles(), user.getUserName(),
                SecurityConstants.BCRYPT + user.getPassword(),
                StrUtil.equals("0", CommonConstants.STATUS_NORMAL), true, true, true, authorities);
        Cache cache = cacheManager.getCache(CacheConstants.USER_DETAILS);
        if (cache != null) {
            cache.put(user.getUserName(), userDetails);
        }
        ItduUser itduUser = new ItduUser(user.getUserId(),postId, user.getDeptId(), user.getRoles(), user.getUserName(), N_A, true, true, true, true, authorities);

        //替换oauth认证的信息里的details，这里就不展示了
       if (authentication instanceof OAuth2Authentication) {
            OAuth2Authentication originalOAuth2Authentication = (OAuth2Authentication) authentication;
            if (!originalOAuth2Authentication.isClientOnly()) {
                Authentication userAuthentication = originalOAuth2Authentication.getUserAuthentication();
                if (userAuthentication instanceof UsernamePasswordAuthenticationToken) {
                        //替换用户信息,权限信息根据自己的需求替换，这里直接取原来的
                        UsernamePasswordAuthenticationToken usernamePasswordAuthentication = new UsernamePasswordAuthenticationToken(itduUser, N_A, authorities);
                        usernamePasswordAuthentication.setDetails(itduUser);
                        OAuth2Authentication oauth2Authentication = new OAuth2Authentication(originalOAuth2Authentication.getOAuth2Request(), usernamePasswordAuthentication);
                        oauth2Authentication.setDetails(itduUser);
                    String key = authenticationKeyGenerator.extractKey(originalOAuth2Authentication);
                    byte[] serializedKey =  serializationStrategy.serialize(CacheConstants.PROJECT_OAUTH_ACCESS+"auth_to_access:" + key);
                    byte[] bytes = null;
                    RedisConnection conn = redisConnectionFactory.getConnection();
                    try {
                        bytes = conn.get(serializedKey);
                    } finally {
                        conn.close();
                    }
                    OAuth2AccessToken accessToken =serializationStrategy.deserialize(bytes,OAuth2AccessToken.class);
                    accessToken.getAdditionalInformation().put(SecurityConstants.DETAILS_POST_ID,postId);
                        tokenStore.storeAccessToken(accessToken,oauth2Authentication);
                }
            }
        }

后期使用

SecurityContextHolder.getContext().getAuthentication()   即可获取到当前登陆用户的相关信息
