+##### 指定特定命名的配置文件的解析方式
+
+可以使用`@regist_config_file_parser(config_file_name)`来注册如何解析特定命名的配置文件.这一特性可以更好的定制化配置文件的读取

+```python
+class Test_AC(EntryPoint):
+    load_all_config_file = True
+    default_config_file_paths = [
+        "./test_config.json",

+    with open(p) as f:
+        temp = json.load(f)
+    return {k.lower(): v for k, v in temp.items()}
+
+```
+
+如果想在定义子类时固定好,也可以定义`_config_file_parser_map:Dict[str,Callable[[Path], Dict[str, Any]]]`
+
+```python
+def test_other_config2_parser( p: Path) -> Dict[str, Any]:
+    with open(p) as f:
+        temp = json.load(f)
