自动生成MySQL DDL建表语句

Introduction

In most projects, MySQL is used with common data types like char, varchar, date, datetime, timestamp, int, and tinyint. A standard table design document is usually required for table design. Such standardized documentation allows for the generation of data table creation statements by parsing xlsx files.

pom.xml File Inclusion

The project includes libraries such as poi for parsing xlsx files and logback for logging functionality. The dependencies are listed with their respective artifactIds like 'poi', 'poi-ooxml', 'commons-lang3', 'hutool-all', 'slf4j-api', and 'logback' components, specifying their versions.

Creation of Table and Column Entities

The TableScriptDO and ColumnScriptDO entities are created for representing table and column scripts. The TableScriptDO object contains the table name and comments, while the ColumnScriptDO object holds the column name, comments, primary key name, auto-increment flag, type, length, nullability, and default value. Getters and setters are provided for these objects.

Parsing the Spreadsheet (xlsx)

Parsing of the table structure design document is performed using the POI library. AutoTableXlsxUtils class contains methods to read xlsx files, extract workbook information, and generate table script objects. It handles the retrieval of sheets, rows, and cells, including cell type and content, to compose the list of TableScriptDO objects representing the database schema.
