-对于示例中的包名表达式，说明如下：
-
-1. 仅支持以下配置项使用表达式
-    ```text
-    processor.allInTables.package
-    processor.mapper.package
-    processor.tableDef.package
-    ```
-2. `${entityPackage}`: 表示 Entity 类所在的包名
-3. `${entityPackage.parent}`: 表示 Entity 类所在的上一级包名
-4. `parent` 参数的数量没有限制，但如果超出了可能的层级，则会导致异常
 
 **示例配置:**
 
 假设 Example 类的全限定类名为 `com.mybatisflex.entity.Example`
 
-配置内容如下:
-
-```properties
-processor.allInTables.package=${entityPackage}.table
-processor.mapper.package=${entityPackage.parent}.mapper
-processor.tableDef.package=${entityPackage.parent.parent}.table
-```
 
 生成类的全限定类名如下:
