java编写仓库管理系统课程设计

仓库管理系统是一个复杂的系统，涉及到多个模块和功能，以下是一个简单的Java仓库管理系统的设计方案：

1、项目结构

仓库管理系统
├─src
│  ├─main
│  │  ├─java
│  │  │  ├─com
│  │  │  │  ├─example
│  │  │  │  │  └─warehousemanagement
│  │  │  │  │      ├─entity
│  │  │  │  │      ├─mapper
│  │  │  │  │      ├─service
│  │  │  │  │      └─controller
│  │  │  │  ├─resources
│  │  │  │  └─static
│  │  │  └─test
│  │  └─resources
│  └─webapp
│      ├─WEBINF
│      ├─index.jsp
│      └─WEBINF
│          └─classes
│              └─example
│                  └─warehousemanagement
│                      ├─entity
│                      ├─mapper
│                      ├─service
│                      └─controller
│      └─lib
│          └─mysqlconnectorjava8.0.23.jar
└─pom.xml

2、实体类（Entity）

package com.example.warehousemanagement.entity;
public class Product {
    private Integer id;
    private String name;
    private Integer quantity;
    private Double price;
    // getter and setter methods
}

3、Mapper接口（Mapper）

package com.example.warehousemanagement.mapper;
import com.example.warehousemanagement.entity.Product;
import java.util.List;
public interface ProductMapper {
    List<Product> findAll();
    Product findById(Integer id);
    void insert(Product product);
    void update(Product product);
    void delete(Integer id);
}

4、Service接口（Service）

package com.example.warehousemanagement.service;
import com.example.warehousemanagement.entity.Product;
import java.util.List;
public interface ProductService {
    List<Product> findAll();
    Product findById(Integer id);
    void insert(Product product);
    void update(Product product);
    void delete(Integer id);
}

5、Service实现类（ServiceImpl）

package com.example.warehousemanagement.service.impl;
import com.example.warehousemanagement.entity.Product;
import com.example.warehousemanagement.mapper.ProductMapper;
import com.example.warehousemanagement.service.ProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class ProductServiceImpl implements ProductService {
    @Autowired
    private ProductMapper productMapper;
    @Override
    public List<Product> findAll() {
        return productMapper.findAll();
    }
    @Override
    public Product findById(Integer id) {
        return productMapper.findById(id);
    }
    @Override
    public void insert(Product product) {
        productMapper.insert(product);
    }
    @Override
    public void update(Product product) {
        productMapper.update(product);
    }
    @Override
    public void delete(Integer id) {
        productMapper.delete(id);
    }
}

6、Controller类（Controller）

package com.example.warehousemanagement.controller;
import com.example.warehousemanagement.entity.Product;
import com.example.warehousemanagement.service.ProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@Controller
@RequestMapping("/product")
public class ProductController {
    @Autowired
    private ProductService productService;
    @GetMapping("/list")
    public String list(Model model) {
        List<Product> products = productService.findAll();
        model.addAttribute("products", products);
        return "product/list";
    }
    @GetMapping("/detail/{id}")
    public String detail(@PathVariable Integer id, Model model) {
        Product product = productService.findById(id);
        model.addAttribute("product", product);
        return "product/detail";
    }
    @GetMapping("/add")
    public String add(Model model) {
        model.addAttribute("product", new Product());
        return "product/add";
    }
    @PostMapping("/save")
    public String save(@ModelAttribute Product product) {
        productService.insert(product);
        return "redirect:/product/list";
    }
    @GetMapping("/edit/{id}")
    public String edit(@PathVariable Integer id, Model model) {
        Product product = productService.findById(id);
        model.addAttribute("product", product);
        return "product/edit";
    }
    @PostMapping("/update")
    public String update(@ModelAttribute Product product) {
        productService.update(product);
        return "redirect:/product/list";
    }
    @GetMapping("/delete/{id}")
    public String delete(@PathVariable Integer id) {
        productService.delete(id);
        return "redirect:/product/list";
    }
}

7、JSP页面（list.jsp、detail.jsp、add.jsp、edit.jsp）

这些页面需要根据实际需求进行编写，这里不再赘述。
