Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fu-orm-code-generator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

generate_orm_code: Batch generate ORM code from database table structures
visit_online_templates: Browse available online templates
download_online_template: Download templates from remote server
choose_local_template: Select a local template for code generation
visit_local_templates: View locally available templates
set_user_info: Configure user information for code comments
get_user_info: View current user configuration

Example Usage

// Generate ORM code for multiple tables
{
  "basePackage": "com.example.project",
  "mainSourceDirectory": "/path/to/project/src/main/java",
  "tables": [
    {
      "tableName": "user_info",
      "remark": "User information table",
      "fields": [
        {
          "fieldName": "id",
          "dataType": "BIGINT",
          "remark": "User ID"
        },
        {
          "fieldName": "user_name",
          "dataType": "VARCHAR",
          "remark": "Username"
        }
      ]
    }
  ]
}

Generated Code Structure

For a table named user_info, the generator creates:

Entity: com.example.entity.UserInfo.java
Mapper: com.example.mapper.UserInfoMapper.java
Repository: com.example.repository.IUserInfoRepository.java
Service: com.example.service.IUserInfoService.java
Controller: com.example.controller.UserInfoController.java

Type Mappings

Database Type	Java Type
TINYINT, SMALLINT, INT, INTEGER	java.lang.Integer
BIGINT	java.lang.Long
FLOAT, DOUBLE, DECIMAL, NUMERIC	java.math.BigDecimal
CHAR, VARCHAR, TEXT, etc.	java.lang.String
DATE, TIME, DATETIME, TIMESTAMP	java.lang.String
BOOLEAN, BOOL, BIT	java.lang.Boolean

Configuration

The server stores configuration in data/config.json and supports:

Template selection
User information (author name and email)
Custom template directories

Templates

Two built-in templates are available:

mybatis_plus: Standard MyBatis Plus template
期货管理平台(无需审批): Enterprise futures management platform template

Architecture

The project follows a clean layered architecture:

Presentation Layer: MCP tool handlers
Application Layer: Business logic services
Domain Layer: Core entities and repository interfaces
Infrastructure Layer: Concrete implementations

Requirements
