 请先在编写代码的模块，检查是否存在`WorkSheetHandler.java`或者`SimpleWorkSheet.java`类，若存在则直接使用工单，不存在则不使用工单。
 
-## 使用方法
+## 使用案例
 
-1. 调用`WorkSheetHandler.java`中的`putObjectParam`或者`putStringParam`方法创建一条异步执行的任务。
-2. 创建一个**SpringBean**实现`SimpleWorkSheet.java`接口，实现`getWorkCode`方法时，按照业务属性去定义一个字符串，例如："ORDER_CREATE"，在`execute`方法处理业务逻辑。

+调用方使用`tryOrderCreate`方法，遇到异常将自动处理重试逻辑。
