news/2025/3/6 18:43:37/文章来源:https://www.cnblogs.com/WOZHENDEAIJAVA/p/18756104

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

环境准备
工具：IntelliJ IDEA、Navicat、MySQL。

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

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。

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
