# 模块说明
gateway：
> 网关服务，负责请求转发和鉴权功能，整合Spring Security+Oauth2

auth:
> Oauth2认证服务，负责对登录用户进行认证，整合Spring Security+Oauth2

其他服务:
> 受保护的API服务，用户鉴权通过后可以访问该服务，不整合Spring Security+Oauth2

business:
业务后台，提供业务逻辑
<br>
技术栈包括：
- 自定义starter
- kafka
- Elasticsearch


fileSystem：
文件操作、云存储：阿里云使用
<br>
技术栈包括：
- 多数据源配置
- 定时任务
- util读取yml



# Gateway
## AuthorizationManager
这个类里面进行的路径的鉴权，执行的逻辑是匹配URL和roleName进行一一比对



# 问题梳理
## nacos 启动 config 报错
见我自己写的博客

# stream操作
```java
//拿到所有的id，去查询推广码URL
List<Long> posterIds = relationList.stream().map(ChannelActivityRelation::getPromotionCodeId).collect(Collectors.toList());

promotionPosterMap = posterList.stream().collect(Collectors.toMap(PromotionCode::getId, item -> item));
List<Long> channelIds = channelInfoList.stream().map(ChannelInfo::getChannelId).collect(Collectors.toList());
// 		Map<Long, ChannelInfo> channelInfoMap = channelInfoList.stream().collect(Collectors.toMap(ChannelInfo::getChannelId, item -> item));

// 		if (StringUtils.isBlank(ao.getChannelName())) {
// 			List<Long> channelIds = relationList.stream().map(ChannelActivityRelation::getChannelId).collect(Collectors.toList());
// 			List<ChannelInfo> channelInfos = channelInfoMapper.queryChannelInfoByChannelIds(channelIds);
// 			channelInfoMap = channelInfos.stream().collect(Collectors.toMap(ChannelInfo::getChannelId, item -> item));
// 		}

// 		List<Long> channelIds = relationList.stream().map(ChannelActivityRelation::getChannelId).collect(Collectors.toList());
