基本设置
Profile文件中配置资源构建路径和资源首次加载路径，资源如何设置了缓存，在首次加载之后会将再用缓存在缓存目录，后面将直接从缓存目录中读取，方便项目发包时候进行使用
AddressableAssetSettings文件
DisableCatalogUpdateOnStartup 勾选改选项，禁止自动更新，项目资源下载一般需要提示玩家下载资源大小和下载进度，需要通过代码进行手动下载更新
BuildRemoteCatalog 创建远端资源的catalog，用于热更新资源
设置BuildPath和 LoadPath
根据自身网络状况设置资源最大的请求数和下载超时时间
Group文件注意设置BundleMode ,是否将group内的资源分散打包
Remote资源缓存
unity自身默认缓存路径是 C:\Users\admin\AppData\LocalLow\Unity
Addressable默认缓存路径 C:\Users\admin\AppData\LocalLow\Unity\项目名称_AdressableLoad
可以指定远端远端资源在本地缓存路径，需要注意的是，如果项目刚开始运行的时候没有手动设置缓存目录，在手动添加缓存目录之后默认缓存目录中已经存在的资源并不会被释放，每次加载读取的时候，先从手动设置的缓存目录中查找，在从默认缓存中查找，如果默认缓存中存在资源，则不会重新进行下载
创建CacheInitializationSettings文件，然后将改文件关联到AddressableAssetSettings的inititalizationObjects中，方法如下
手动设置缓存路径（如下图所示方式会缓存在工程根目录的AAAAAAA文件夹内，也可设置为 persistentDataPath 格式为{UnityEngine.Application.persistentDataPath}）
每一个下载下来的bundle资源，会被缓存为_data 和_info两个文件，（猜测：_info是索引文件信息，_data是资源序列化内容）
