   1. 通过注解

    public class StudentManager {
 
     @ResInjection
-    private Storage<Integer, StudentResource> studentResources;
+    private IStorage<Integer, StudentResource> studentStorage;
 
     }
   ```
   2. 通过类动态获取
   ```
-  Storage<Integer, StudentResource> studentResources = (Storage<Integer, StudentResource>) StorageContext.getStorageManager().getStorage(StudentResource.class);
+  IStorage<Integer, StudentResource> studentStorage = StorageContext.getStorageManager().getStorage(StudentResource.class);
   ```
 
 - 通过id找到对应的行
 
 ```
-var studentResource = studentResources.get(1000);
+var studentResource = studentStorage.get(1000);
+```
+
+或者也可以通过如下方式获取
+```
+var resource = StorageContext.get(StudentResource.class, 1001);
 ```
 
 - 通过索引找对应的行，默认为可重复的索引，返回了一个列表list
 
 ```
-var students = studentResources.getIndex("name", "james0");
+var students = studentStorage.getIndexes(StudentResource::getName, "james0");
+```
+
+如果你是record类则使用方式如下
+```
+var students = studentStorage.getIndexes(StudentResource::name, "james0");
 ```
 
 - 唯一索引通过Storage.getUniqueIndex()获取，需要把索引注解标注为@Index(unique = true)
 
+```
+StudentResource student = storage.getUniqueIndex(StudentResource::idCard, "110101200007281903");
+```
