P8Gen

P8Gen是一个用于生成代码的工具，开发之初是为了特定场景下根据特定配置生成代码和配置文件等。在后续开发中不断扩展，目前P8Gen已经是一个功能齐全的Java代码生成工具。

P8Gen is a tool for generating code, the initial purpose of development is to generate code and configuration files for specific scenarios based on specific configurations. It will be expanded in subsequent development, now P8Gen has been a fully functional Java code generation tool

安装 Install

下载源码，作为普通java项目导入到IDEA或者Eclipse中

Download the source code and import it into IDEA or Eclipse as a normal Java project

使用 Usage

1. 参考resources目录中P8TradeInfo.txt文件，新建一个文件，配置好要生成的交易相关的属性
2. 找到Main.java，修改basePackage[生成的代码将以此包路径为根路径]和fileName[上一步配置好的文件]这两个属性
3. 运行Main.java的main方法

• a. Refer to the p8Tradeinfo.txt file in the Resources directory, create a new file, and configure the properties of the transaction to be generated
• b. Find main.java and change the basePackage(the generated code will be rooted from this package path) and fileName(the file configured in the previous step) properties
• c. Run the main() method in Main.java

举例🌰 Example

编辑 P8TradeInfo.txt 如下：

Edit P8TradeInfo.txt like this:
