基于SSM（Spring + Spring MVC + MyBatis）框架构建一个图书馆仓储管理系统

基于SSM（Spring + Spring MVC + MyBatis）框架构建一个图书馆仓储管理系统是一个涉及多个功能模块的项目，包括但不限于图书管理、读者管理、借阅管理、归还管理等。

1. 环境准备

确保你已经安装了以下工具和环境：

Java Development Kit (JDK)
集成开发环境 (IDE)：如Eclipse, IntelliJ IDEA
数据库：如MySQL, PostgreSQL
构建工具：如Maven或Gradle
服务器：如Apache Tomcat

2. 项目结构

创建一个新的Maven项目，并设置好目录结构。通常的Maven项目结构如下：

library-management-system
├── src
│   ├── main
│   │   ├── java
│   │   │   └── com.example.lms
│   │   ├── resources
│   │   │   ├── mappers
│   │   │   ├── application.properties
│   │   │   └── mybatis-config.xml
│   │   └── webapp
│   │       ├── WEB-INF
│   │       │   ├── views
│   │       │   ├── web.xml
│   │       │   └── spring-servlet.xml
│   │       └── index.jsp
│   └── test
│       └── java
│           └── com.example.lms
└── pom.xml

3. Maven依赖配置 (pom.xml)

在pom.xml中添加必要的依赖项：

<dependencies><!-- Spring --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>5.3.22</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.3.22</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>5.3.22</version></dependency><!-- MyBatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.10</version></dependency><dependency><groupId>org.mybatis.spring</groupId><artifactId>mybatis-spring</artifactId><version>2.0.6</version></dependency><!-- MySQL Connector --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.29</version></dependency><!-- Servlet API --><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>4.0.1</version><scope>provided</scope></dependency><!-- JSP, JSTL --><dependency><groupId>javax.servlet.jsp</groupId><artifactId>javax.servlet.jsp-api</artifactId><version>2.3.3</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency>
</dependencies>

4. 数据库设计

设计几个基本的表来支持图书馆的主要功能：

books：存储书籍信息。
readers：存储读者信息。
borrow_records：记录借阅信息。
return_records：记录归还信息。

示例SQL语句：

CREATE TABLE books (id INT AUTO_INCREMENT PRIMARY KEY,title VARCHAR(255) NOT NULL,author VARCHAR(255),isbn VARCHAR(13) UNIQUE,publisher VARCHAR(255),publish_date DATE,category VARCHAR(100),available_copies INT DEFAULT 0
);CREATE TABLE readers (id INT AUTO_INCREMENT PRIMARY KEY,name VARCHAR(100) NOT NULL,gender ENUM('M', 'F') NOT NULL,birth_date DATE,phone_number VARCHAR(20),address TEXT
);CREATE TABLE borrow_records (id INT AUTO_INCREMENT PRIMARY KEY,reader_id INT NOT NULL,book_id INT NOT NULL,borrow_date DATE NOT NULL,due_date DATE NOT NULL,FOREIGN KEY (reader_id) REFERENCES readers(id),FOREIGN KEY (book_id) REFERENCES books(id)
);CREATE TABLE return_records (id INT AUTO_INCREMENT PRIMARY KEY,borrow_record_id INT NOT NULL,return_date DATE NOT NULL,FOREIGN KEY (borrow_record_id) REFERENCES borrow_records(id)
);

5. DAO层 (MyBatis Mapper)

为每个实体创建对应的Mapper接口和XML映射文件。

BookMapper.java:

package com.example.lms.dao;import com.example.lms.model.Book;
import org.apache.ibatis.annotations.*;import java.util.List;@Mapper
public interface BookMapper {@Select("SELECT * FROM books WHERE id = #{id}")Book selectById(Integer id);@Insert("INSERT INTO books(title, author, isbn, publisher, publish_date, category, available_copies) VALUES(#{title}, #{author}, #{isbn}, #{publisher}, #{publishDate}, #{category}, #{availableCopies})")@Options(useGeneratedKeys = true, keyProperty = "id")void insert(Book book);@Update("UPDATE books SET title=#{title}, author=#{author}, isbn=#{isbn}, publisher=#{publisher}, publish_date=#{publishDate}, category=#{category}, available_copies=#{availableCopies} WHERE id=#{id}")void update(Book book);@Delete("DELETE FROM books WHERE id=#{id}")void deleteById(Integer id);@Select("SELECT * FROM books")List<Book> selectAll();
}

ReaderMapper.java:

package com.example.lms.dao;import com.example.lms.model.Reader;
import org.apache.ibatis.annotations.*;import java.util.List;@Mapper
public interface ReaderMapper {@Select("SELECT * FROM readers WHERE id = #{id}")Reader selectById(Integer id);@Insert("INSERT INTO readers(name, gender, birth_date, phone_number, address) VALUES(#{name}, #{gender}, #{birthDate}, #{phoneNumber}, #{address})")@Options(useGeneratedKeys = true, keyProperty = "id")void insert(Reader reader);@Update("UPDATE readers SET name=#{name}, gender=#{gender}, birth_date=#{birthDate}, phone_number=#{phoneNumber}, address=#{address} WHERE id=#{id}")void update(Reader reader);@Delete("DELETE FROM readers WHERE id=#{id}")void deleteById(Integer id);@Select("SELECT * FROM readers")List<Reader> selectAll();
}

6. Service层

BookService.java:

package com.example.lms.service;import com.example.lms.dao.BookMapper;
import com.example.lms.model.Book;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;@Service
public class BookService {@Autowiredprivate BookMapper bookMapper;public Book getBookById(Integer id) {return bookMapper.selectById(id);}public List<Book> getAllBooks() {return bookMapper.selectAll();}public void addBook(Book book) {bookMapper.insert(book);}public void updateBook(Book book) {bookMapper.update(book);}public void deleteBook(Integer id) {bookMapper.deleteById(id);}
}

ReaderService.java:

package com.example.lms.service;import com.example.lms.dao.ReaderMapper;
import com.example.lms.model.Reader;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;@Service
public class ReaderService {@Autowiredprivate ReaderMapper readerMapper;public Reader getReaderById(Integer id) {return readerMapper.selectById(id);}public List<Reader> getAllReaders() {return readerMapper.selectAll();}public void addReader(Reader reader) {readerMapper.insert(reader);}public void updateReader(Reader reader) {readerMapper.update(reader);}public void deleteReader(Integer id) {readerMapper.deleteById(id);}
}

7. Controller层

BookController.java:

package com.example.lms.controller;import com.example.lms.model.Book;
import com.example.lms.service.BookService;
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("/books")
public class BookController {@Autowiredprivate BookService bookService;@GetMappingpublic String listBooks(Model model) {List<Book> books = bookService.getAllBooks();model.addAttribute("books", books);return "bookList";}@GetMapping("/{id}")public String viewBook(@PathVariable Integer id, Model model) {Book book = bookService.getBookById(id);model.addAttribute("book", book);return "bookView";}@PostMappingpublic String addBook(@ModelAttribute Book book) {bookService.addBook(book);return "redirect:/books";}@PutMapping("/{id}")public String updateBook(@PathVariable Integer id, @ModelAttribute Book book) {book.setId(id);bookService.updateBook(book);return "redirect:/books/" + id;}@DeleteMapping("/{id}")public String deleteBook(@PathVariable Integer id) {bookService.deleteBook(id);return "redirect:/books";}
}

ReaderController.java:

package com.example.lms.controller;import com.example.lms.model.Reader;
import com.example.lms.service.ReaderService;
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("/readers")
public class ReaderController {@Autowiredprivate ReaderService readerService;@GetMappingpublic String listReaders(Model model) {List<Reader> readers = readerService.getAllReaders();model.addAttribute("readers", readers);return "readerList";}@GetMapping("/{id}")public String viewReader(@PathVariable Integer id, Model model) {Reader reader = readerService.getReaderById(id);model.addAttribute("reader", reader);return "readerView";}@PostMappingpublic String addReader(@ModelAttribute Reader reader) {readerService.addReader(reader);return "redirect:/readers";}@PutMapping("/{id}")public String updateReader(@PathVariable Integer id, @ModelAttribute Reader reader) {reader.setId(id);readerService.updateReader(reader);return "redirect:/readers/" + id;}@DeleteMapping("/{id}")public String deleteReader(@PathVariable Integer id) {readerService.deleteReader(id);return "redirect:/readers";}
}

8. 配置文件

9. 视图层 (JSP)

为书籍和读者列表创建简单的JSP页面。

bookList.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head><meta charset="UTF-8"><title>Book List</title>
</head>
<body>
<h1>Book List</h1>
<table border="1"><tr><th>ID</th><th>Title</th><th>Author</th><th>ISBN</th><th>Publisher</th><th>Publish Date</th><th>Category</th><th>Available Copies</th><th>Actions</th></tr><c:forEach var="book" items="${books}"><tr><td>${book.id}</td><td>${book.title}</td><td>${book.author}</td><td>${book.isbn}</td><td>${book.publisher}</td><td>${book.publishDate}</td><td>${book.category}</td><td>${book.availableCopies}</td><td><a href="/books/${book.id}">View</a><a href="/books/${book.id}/edit">Edit</a><a href="/books/${book.id}/delete" οnclick="return confirm('Are you sure you want to delete this book?')">Delete</a></td></tr></c:forEach>
</table>
<a href="/books/new">Add New Book</a>
</body>
</html>

readerList.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head><meta charset="UTF-8"><title>Reader List</title>
</head>
<body>
<h1>Reader List</h1>
<table border="1"><tr><th>ID</th><th>Name</th><th>Gender</th><th>Birth Date</th><th>Phone Number</th><th>Address</th><th>Actions</th></tr><c:forEach var="reader" items="${readers}"><tr><td>${reader.id}</td><td>${reader.name}</td><td>${reader.gender}</td><td>${reader.birthDate}</td><td>${reader.phoneNumber}</td><td>${reader.address}</td><td><a href="/readers/${reader.id}">View</a><a href="/readers/${reader.id}/edit">Edit</a><a href="/readers/${reader.id}/delete" οnclick="return confirm('Are you sure you want to delete this reader?')">Delete</a></td></tr></c:forEach>
</table>
<a href="/readers/new">Add New Reader</a>
</body>
</html>
