用ai进行编程

应我们帅气的王老师的要求，这是ai对如何进行java项目（springboot）开发的回答

1. 环境准备
   工具：IntelliJ IDEA、Navicat、MySQL。

技术栈：Spring Boot、Spring Data JPA、Thymeleaf（模板引擎）、MySQL。

2. 创建Spring Boot项目
   打开IntelliJ IDEA → New Project → Spring Initializr。

填写项目信息：

Group: com.example

Artifact: warehouse-system

Type: Maven

选择依赖：

Spring Web（Web应用）

Spring Data JPA（数据库操作）

MySQL Driver（MySQL连接）

Thymeleaf（模板引擎）

点击 Finish 完成创建。

3. 项目结构
   复制
   src/main/java
   └── com.example.warehousesystem
   ├── controller # 控制层（处理HTTP请求）
   ├── service # 服务层（业务逻辑）
   ├── repository # 数据访问层（数据库操作）
   ├── model # 实体类（映射数据库表）
   ├── config # 配置类（如安全配置）
   └── WarehouseSystemApplication.java # 启动类

src/main/resources
├── static # 静态资源（CSS/JS）
├── templates # 页面模板（HTML）
└── application.properties # 配置文件
4. 配置数据库
4.1 创建数据库表
在Navicat中执行以下SQL（与之前的表结构相同）：

sql
复制
-- 仓库表
CREATE TABLE warehouse (
warehouse_id VARCHAR(20) PRIMARY KEY,
warehouse_name VARCHAR(100) NOT NULL
);

-- 物资类别表
CREATE TABLE material_category (
category_id VARCHAR(20) PRIMARY KEY,
category_name VARCHAR(100) NOT NULL,
specification VARCHAR(100),
material VARCHAR(100),
UNIQUE (category_name, specification, material)
);

-- 物资台账表
CREATE TABLE material_ledger (
ledger_id VARCHAR(20) PRIMARY KEY,
material_id VARCHAR(20) NOT NULL,
operation_type ENUM('IN', 'OUT') NOT NULL,
quantity INT NOT NULL,
unit VARCHAR(20),
warehouse_id VARCHAR(20),
operation_date DATETIME DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (material_id) REFERENCES material_category(category_id),
FOREIGN KEY (warehouse_id) REFERENCES warehouse(warehouse_id)
);
4.2 配置数据库连接
在 src/main/resources/application.properties 中添加：

properties
复制

数据库配置

spring.datasource.url=jdbc:mysql://localhost:3306/warehouse_management?useSSL=false
spring.datasource.username=root
spring.datasource.password=your_password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

JPA配置

spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
5. 编写实体类
5.1 仓库实体 (model/Warehouse.java)
java
复制
package com.example.warehousesystem.model;

import jakarta.persistence.*;

@Entity
@Table(name = "warehouse")
public class Warehouse {
@Id
@Column(name = "warehouse_id")
private String warehouseId;

@Column(name = "warehouse_name")
private String warehouseName;

// Getters and Setters

}
5.2 物资类别实体 (model/MaterialCategory.java)
java
复制
package com.example.warehousesystem.model;

import jakarta.persistence.*;

@Entity
@Table(name = "material_category")
public class MaterialCategory {
@Id
@Column(name = "category_id")
private String categoryId;

@Column(name = "category_name")
private String categoryName;

private String specification;
private String material;

// Getters and Setters

}
5.3 物资台账实体 (model/MaterialLedger.java)
java
复制
package com.example.warehousesystem.model;

import jakarta.persistence.*;
import java.util.Date;

@Entity
@Table(name = "material_ledger")
public class MaterialLedger {
@Id
@Column(name = "ledger_id")
private String ledgerId;

@ManyToOne
@JoinColumn(name = "material_id", referencedColumnName = "category_id")
private MaterialCategory material;

@Column(name = "operation_type")
private String operationType;

private int quantity;
private String unit;

@ManyToOne
@JoinColumn(name = "warehouse_id", referencedColumnName = "warehouse_id")
private Warehouse warehouse;

@Column(name = "operation_date")
@Temporal(TemporalType.TIMESTAMP)
private Date operationDate;

// Getters and Setters

}
6. 编写Repository接口
6.1 仓库Repository (repository/WarehouseRepository.java)
java
复制
package com.example.warehousesystem.repository;

import com.example.warehousesystem.model.Warehouse;
import org.springframework.data.jpa.repository.JpaRepository;

public interface WarehouseRepository extends JpaRepository<Warehouse, String> {
}
6.2 物资类别Repository (repository/MaterialCategoryRepository.java)
java
复制
package com.example.warehousesystem.repository;

import com.example.warehousesystem.model.MaterialCategory;
import org.springframework.data.jpa.repository.JpaRepository;

public interface MaterialCategoryRepository extends JpaRepository<MaterialCategory, String> {
}
7. 编写Service层
7.1 仓库Service (service/WarehouseService.java)
java
复制
package com.example.warehousesystem.service;

import com.example.warehousesystem.model.Warehouse;
import com.example.warehousesystem.repository.WarehouseRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class WarehouseService {
@Autowired
private WarehouseRepository warehouseRepository;

public List<Warehouse> getAllWarehouses() {
    return warehouseRepository.findAll();
}

public Warehouse saveWarehouse(Warehouse warehouse) {
    return warehouseRepository.save(warehouse);
}

public void deleteWarehouse(String id) {
    warehouseRepository.deleteById(id);
}

}
8. 编写Controller层
8.1 仓库Controller (controller/WarehouseController.java)
java
复制
package com.example.warehousesystem.controller;

import com.example.warehousesystem.model.Warehouse;
import com.example.warehousesystem.service.WarehouseService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;

@Controller
@RequestMapping("/warehouses")
public class WarehouseController {
@Autowired
private WarehouseService warehouseService;

@GetMapping
public String listWarehouses(Model model) {
    model.addAttribute("warehouses", warehouseService.getAllWarehouses());
    return "warehouse/list";
}

@GetMapping("/new")
public String createWarehouseForm(Model model) {
    model.addAttribute("warehouse", new Warehouse());
    return "warehouse/create";
}

@PostMapping
public String saveWarehouse(@ModelAttribute("warehouse") Warehouse warehouse) {
    warehouseService.saveWarehouse(warehouse);
    return "redirect:/warehouses";
}

@GetMapping("/delete/{id}")
public String deleteWarehouse(@PathVariable String id) {
    warehouseService.deleteWarehouse(id);
    return "redirect:/warehouses";
}

}
9. 编写前端页面
在 src/main/resources/templates/warehouse 下创建HTML页面：

9.1 仓库列表页 (list.html)
html
复制

仓库列表

新增仓库

仓库编号	仓库名称	操作
		删除

运行 HTML 9.2 新增仓库页 (create.html) html 复制

新增仓库

仓库编号：
仓库名称：
保存

运行 HTML 10. 运行和测试 启动 WarehouseSystemApplication.java。

访问 http://localhost:8080/warehouses 查看仓库列表。

点击“新增仓库”测试添加功能。

11. 扩展功能
    权限控制：使用 Spring Security 区分管理员和仓库人员。

台账操作：在 MaterialLedgerController 中实现入库/出库逻辑。

数据校验：在实体类中添加 @NotBlank 等注解校验输入。

通过以上步骤，你可以快速构建一个基础的 Spring Boot 仓储管理系统。如果需要更复杂的逻辑（如台账操作、权限管理），可以在此基础上逐步扩展。
