概述

通過對數據庫中一張表的CRUD，將相應的操作結果渲染到頁面上。
如果想查看Spring Boot架構的同等規模的項目，可參考此篇博客Spring Boot項目實例——簡易版商城管理系統
由于廣大讀者要求源碼，作者通過這篇博客還原了項目（當然有一些隱藏的坑），然后將該項目上傳到了Gitee，在末尾的后記部分有源碼地址，讀者可參考。

準備

• 環境：

  • IDEA
  • MySQL 5.7.19
  • Tomcat 9
  • Maven 3.6

• 要求：

  • 掌握MySQL數據庫
  • 掌握Spring，
  • 掌握SpringMVC
  • 掌握MyBatis知識
  • 掌握簡單的前端知識

實現

1.搭建數據庫

創建一個存放書籍數據的數據庫（ssmbuild），并在該數據庫中建立一個名為books的表，代碼如下：

CREATE DATABASE `ssmbuild`;USE `ssmbuild`;DROP TABLE IF EXISTS `books`;CREATE TABLE `books` (`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '書id',`bookName` VARCHAR(100) NOT NULL COMMENT '書名',`bookCounts` INT(11) NOT NULL COMMENT '數量',`detail` VARCHAR(200) NOT NULL COMMENT '描述',KEY `bookID` (`bookID`) ) ENGINE=INNODB DEFAULT CHARSET=utf8INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES (1,'Java',1,'從入門到放棄'), (2,'MySQL',10,'從刪庫到跑路'), (3,'Linux',5,'從進門到進牢');

寫好數據庫的配置文件database.properties，該文件可以放在resources目錄下，代碼如下：

jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=123456

在Maven中導入數據庫連接所需要的驅動包（mysql-connector），代碼如下：

<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency>

---

2.實現pojo層

在項目的java目錄下新建pojo包，因為數據庫中只有一個表，所以只需要編寫一個實體類Book即可，代碼如下所示：

package pojo;public class Book {private int bookID;private String bookName;private int bookCounts;private String detail;public Book() {}public Book(int bookID, String bookName, int bookCounts, String detail) {this.bookID = bookID;this.bookName = bookName;this.bookCounts = bookCounts;this.detail = detail;}public int getBookID() {return bookID;}public void setBookID(int bookID) {this.bookID = bookID;}public String getBookName() {return bookName;}public void setBookName(String bookName) {this.bookName = bookName;}public int getBookCounts() {return bookCounts;}public void setBookCounts(int bookCounts) {this.bookCounts = bookCounts;}public String getDetail() {return detail;}public void setDetail(String detail) {this.detail = detail;}@Overridepublic String toString() {return "Book{" +"bookID=" + bookID +", bookName='" + bookName + '\'' +", bookCounts=" + bookCounts +", detail='" + detail + '\'' +'}';} }

---

3.實現dao層

在項目的java目錄下新建dao包，編寫dao層接口BookDao即可，代碼如下所示：

package dao;import org.apache.ibatis.annotations.Param; import pojo.Book;import java.util.List;public interface BookDao {//增加一個Booksint addBook(Book books);//根據id刪除Booksint deleteBookByID(@Param("bookID") int id);//更新Booksint updateBook(Book books);//根據id查詢BookBook queryBookByID(@Param("bookID") int id);//查看全部的BookList<Book> queryAllBook();}

在Maven中導入Mybatis所需要的驅動包（mybatis），代碼如下：

<!-- MyBatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.6</version></dependency>

在dao包下編寫對應的映射文件BookMapper.xml，代碼如下：

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="dao.BookDao"><!--//增加一個Books--><insert id="addBook" parameterType="Book">insert into ssmbuild.books(bookID , bookName, bookCounts, detail)values (#{bookID},#{bookName},#{bookCounts},#{detail})</insert><!--//根據id刪除Books--><delete id="deleteBookByID" parameterType="int">delete from ssmbuild.books where bookID = #{bookID}</delete><!--//更新Books--><update id="updateBook" parameterType="Book">update ssmbuild.booksset bookName = #{bookName} , bookCounts = #{bookCounts} ,detail = #{detail}where bookID = #{bookID}</update><!--//根據id查詢Book--><select id="queryBookByID" resultType="Book">select * from ssmbuild.books where bookID = #{bookID}</select><!--//查看全部的Book--><select id="queryAllBook" resultType="Book">select * from ssmbuild.books</select></mapper>

在resources目錄下編寫Mybatis的配置文件Mybatis-config.xml，用于配置別名，以及注冊映射文件，代碼如下：

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration><typeAliases><package name="pojo"/></typeAliases><mappers><mapper resource="dao/BookMapper.xml"></mapper></mappers></configuration>

---

---

4.實現service層

在項目的java目錄下新建service包，編寫service層接口BookService，代碼如下所示：

package service;import org.apache.ibatis.annotations.Param; import pojo.Book;import java.util.List;public interface BookService {//增加一個Booksint addBook(Book books);//根據id刪除Booksint deleteBookByID( @Param("bookID") int id);//更新Booksint updateBook(Book books);//根據id查詢BookBook queryBookByID(@Param("bookID") int id);//查看全部的BookList<Book> queryAllBook();}

在service包下編寫對應的實現類BookServiceImpl，代碼如下：

package service;import dao.BookDao; import pojo.Book;import java.util.List;public class BookServiceImpl implements BookService{// 組合private BookDao bookDao;public void setBookDao(BookDao bookDao) {this.bookDao = bookDao;}@Overridepublic int addBook(Book books) {return bookDao.addBook(books);}@Overridepublic int deleteBookByID(int id) {return bookDao.deleteBookByID(id);}@Overridepublic int updateBook(Book books) {return bookDao.updateBook(books);}@Overridepublic Book queryBookByID(int id) {return bookDao.queryBookByID(id);}@Overridepublic List<Book> queryAllBook() {return bookDao.queryAllBook();} }

---

5.配置Spring整合dao層

在本例中使用c3p0連接池，需要在Maven導入相關的包，代碼如下：

<!-- 數據庫連接池 --><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><!-- mybatis-spring整合包 --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.1</version></dependency><!--Spring相關包--><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.3.24.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.24.RELEASE</version></dependency>

在resources目錄下新建spring文件夾，并在該文件夾中新建一個名為spring-dao.xml的配置文件，用于讓Spring整合mybatis，代碼如下：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><!--整合Mybatis--><!--1.關聯數據庫文件--><context:property-placeholder location="classpath:database.properties"/><!--2.數據庫連接池--><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><!--數據庫的基本配置--><property name="driverClass" value="${jdbc.driver}"/><property name="jdbcUrl" value="${jdbc.url}"/><property name="user" value="${jdbc.username}"/><property name="password" value="${jdbc.password}"/></bean><!--3.sqlSessionFactory--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><!--關聯mybatis--><property name="configLocation" value="classpath:mybatis-config.xml"/></bean><!--4.注冊dao層Bean--><!--動態實現dao接口注入Spring容器中--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><!--綁定sqlSessionFactory--><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/><!--掃描包--><property name="basePackage" value="dao"/></bean><!--5.掃描包--><context:component-scan base-package="dao"/></beans>

---

7.配置Spring整合Spring MVC

修改webapp目錄下的web.xml文件，代碼如下：

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><!--1.DispatchServlet--><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!--關聯Spring配置文件--><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!--2.字符編碼過濾--><!--字符編碼過濾--><filter><filter-name>encodingFilter</filter-name><!--<filter-class>com.kuang.filter.GenericEncodingFilter</filter-class>--><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><!--參數：CharacterEncodingFilter--><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>

在resources/spring文件夾中新建一個名為spring-mvc.xml的配置文件，用于讓Spring整合servlet層，代碼如下：

8.配置Spring整合文件

在resources中新建一個名為applicationContext.xml的配置文件，用于整合上面的spring-dao.xml、spring-service.xml、spring-mvc.xml，代碼如下：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"><!--整合Spring--><import resource="classpath:spring/spring-dao.xml"/><import resource="classpath:spring/spring-service.xml"/><import resource="classpath:spring/spring-mvc.xml"/></beans>

在Maven導入jsp和servlet的包，代碼如下：

<dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.0.1</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.2</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency>

---

9.實現controller層

在項目的java目錄下新建controller包，編寫控制器BookController，代碼如下所示：

package controller;import org.apache.ibatis.annotations.Param; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import pojo.Book; import service.BookService;import java.util.List;@Controller @RequestMapping("/book") public class BookController {@Autowired@Qualifier("bookServiceImpl")private BookService bookService;// 展示全部的書籍@RequestMapping("/allBook")public String list(Model model){List<Book> list = bookService.queryAllBook();model.addAttribute("list",list);return "allBook";}// 跳轉到新增書籍頁面@RequestMapping("/toAddBook")public String toAddBookPage(){return "addBook";}// 增加書籍@RequestMapping("/addBook")public String addBook(Book book){bookService.addBook(book);return "redirect:/book/allBook";}// 跳轉到修改書籍頁面@RequestMapping("/toUpdateBook")public String toUpdateBook(int id,Model model){Book book = bookService.queryBookByID(id);model.addAttribute("book",book);return "updateBook";}// 修改書籍@RequestMapping("/updateBook")public String updateBook(Book book,Model model){bookService.updateBook(book);// 更新最新的書籍Book book1 = bookService.queryBookByID(book.getBookID());model.addAttribute("books",book1);return "redirect:/book/allBook";}// 刪除書籍，使用Restful風格@RequestMapping("/del/{bookID}")public String delete(@PathVariable("bookID") int id){bookService.deleteBookByID(id);return "redirect:/book/allBook";} }

---

10.實現view層

編寫主頁index.jsp，用于進入查看所有圖書的頁面，代碼如下：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> <!DOCTYPE HTML> <html> <head><title>首頁</title><style type="text/css">a {text-decoration: none;color: black;font-size: 18px;}h3 {width: 180px;height: 38px;margin: 100px auto;text-align: center;line-height: 38px;background: deepskyblue;border-radius: 4px;}</style> </head> <body><h3><a href="${pageContext.request.contextPath}/book/allBook">點擊進入列表頁</a> </h3> </body> </html>

在WEB-INF目錄下新建jsp目錄，并在該目錄下編寫allBook.jsp，用于查看所有圖書，代碼如下：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head><title>書籍列表</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> </head> <body><div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>書籍列表 —— 顯示所有書籍</small></h1></div></div></div><div class="row"><div class="col-md-4 column"><a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增</a></div></div><div class="row clearfix"><div class="col-md-12 column"><table class="table table-hover table-striped"><thead><tr><th>書籍編號</th><th>書籍名字</th><th>書籍數量</th><th>書籍詳情</th><th>操作</th></tr></thead><tbody><c:forEach var="book" items="${requestScope.get('list')}"><tr><td>${book.getBookID()}</td><td>${book.getBookName()}</td><td>${book.getBookCounts()}</td><td>${book.getDetail()}</td><td><a href="${pageContext.request.contextPath}/book/toUpdateBook?id=${book.getBookID()}">更改</a> |<a href="${pageContext.request.contextPath}/book/del/${book.getBookID()}">刪除</a></td></tr></c:forEach></tbody></table></div></div> </div>

在WEB-INF/jsp目錄下編寫addBook.jsp，用于添加圖書，代碼如下：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %><html> <head><title>新增書籍</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>新增書籍</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/addBook" method="post">書籍名稱：<input type="text" name="bookName"><br><br><br>書籍數量：<input type="text" name="bookCounts"><br><br><br>書籍詳情：<input type="text" name="detail"><br><br><br><input type="submit" value="添加"></form></div>

在WEB-INF/jsp目錄下編寫updateBook.jsp，用于添加圖書，代碼如下：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head><title>修改信息</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>修改信息</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/updateBook" method="post"><input type="hidden" name="bookID" value="${book.getBookID()}"/>書籍名稱：<input type="text" name="bookName" value="${book.getBookName()}"/>書籍數量：<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>書籍詳情：<input type="text" name="detail" value="${book.getDetail() }"/><input type="submit" value="提交"/></form></div>

11.運行前檢查

Maven的包導入應如下所示（注意添加build標簽中的resources標簽，該標簽用于讓Maven導入相關資源）：

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.moxitao</groupId><artifactId>SSMbuild-test</artifactId><version>1.0-SNAPSHOT</version><packaging>war</packaging><name>SSMbuild-test Maven Webapp</name><!-- FIXME change it to the project's website --><url>http://www.example.com</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><maven.compiler.source>1.7</maven.compiler.source><maven.compiler.target>1.7</maven.compiler.target></properties><dependencies><!--junit部分--><!--測試模塊單元--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><!--Mybatis部分--><!--數據庫驅動包--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency><!--mybatis的包--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.6</version></dependency><!--Mybatis部分完結--><!--Spring部分--><!--mybatis-srping整合包--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.1</version></dependency><!--第三方數據源：c3p0--><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><!--Spring相關的--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.24.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.3.24.RELEASE</version></dependency><!--Spring部分完結--><!--SpringMVC部分--><!--servlet--><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.0.1</version></dependency><!--jsp--><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.2</version></dependency><!--jstl--><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency></dependencies><!--SpringMVC部分完結--><build><finalName>SSMbuild-test</finalName><pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --><plugins><plugin><artifactId>maven-clean-plugin</artifactId><version>3.1.0</version></plugin><!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --><plugin><artifactId>maven-resources-plugin</artifactId><version>3.0.2</version></plugin><plugin><artifactId>maven-compiler-plugin</artifactId><version>3.8.0</version></plugin><plugin><artifactId>maven-surefire-plugin</artifactId><version>2.22.1</version></plugin><plugin><artifactId>maven-war-plugin</artifactId><version>3.2.2</version></plugin><plugin><artifactId>maven-install-plugin</artifactId><version>2.5.2</version></plugin><plugin><artifactId>maven-deploy-plugin</artifactId><version>2.8.2</version></plugin></plugins></pluginManagement><resources><resource><directory>src/main/java</directory><includes><include>**/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>**/*.xml</include><include>**/*.properties</include></includes><filtering>false</filtering></resource></resources></build> </project>

項目目錄如圖所示：

修改書籍頁面（updateBook.jsp）

后記

盡管現在的Java Web項目的開發多用Spring Boot進行搭建，但是使用相對原生的SSM（Spring + Spring MVC + Mybatis）進行開發，不僅能讓我們對于Web項目的搭建流程更加熟悉，還會對我們在日后的學習和工作中大有裨益
項目的源碼地址：SSM版本 簡易管理系統，由于該博客之前有一些細節錯誤尚未修正，這里在搭建項目的時候進行了部分修改。對按照該博客搭建項目后遇到坑的讀者表示抱歉，感謝您的瀏覽！
