Model 可以重写默认的方法，例如 `delete` 方法。 查看 `BussModelDataAccess` 的 `delete` 方法签名是 `public boolean delete(RecordSet rs)` 因此重写 `delete` 方法的时候也要保持方法签名一致 正例 ```java public boolean delete(RecordSet rs) { String[] ids = rs.getIds(); // 其他逻辑 } ``` 反例 下面的方法会导致方法调用的时候，提示 `argument type mismatch` 错误 ```java public boolean delete(List<String> ids) { // 其他逻辑 } ```
