概述

通过对数据库中一张表的CRUD,将相应的操作结果渲染到页面上。
如果想查看Spring Boot架构的同等规模的项目,可参考此篇博客Spring Boot项目实例——简易版商城管理系统
由于广大读者要求源码,作者通过这篇博客还原了项目(当然有一些隐藏的坑),然后将该项目上传到了Gitee,在末尾的后记部分有源码地址,读者可参考。

准备

  • 环境:

    • IDEA
    • MySQL 5.7.19
    • Tomcat 9
    • Maven 3.6
  • 要求:

    • 掌握MySQL数据库
    • 掌握Spring,
    • 掌握SpringMVC
    • 掌握MyBatis知识
    • 掌握简单的前端知识

实现

1.搭建数据库

  1. 创建一个存放书籍数据的数据库(ssmbuild),并在该数据库中建立一个名为books的表,代码如下:
CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

DROP TABLE IF EXISTS `books`;

CREATE TABLE `books` (
  `bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
  `bookName` VARCHAR(100) NOT NULL COMMENT '书名',
  `bookCounts` INT(11) NOT NULL COMMENT '数量',
  `detail` VARCHAR(200) NOT NULL COMMENT '描述',
  KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES 
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
  1. 写好数据库的配置文件database.properties,该文件可以放在resources目录下,代码如下:
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
  1. 在Maven中导入数据库连接所需要的驱动包(mysql-connector),代码如下:
    <dependency>
      <groupId>mysqlgroupId>
      <artifactId>mysql-connector-javaartifactId>
      <version>5.1.47version>
    dependency>

2.实现pojo层

在项目的java目录下新建pojo包,因为数据库中只有一个表,所以只需要编写一个实体类Book即可,代码如下所示:

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;
    }

    @Override
    public String toString() {
        return "Book{" +
                "bookID=" + bookID +
                ", bookName='" + bookName + '\'' +
                ", bookCounts=" + bookCounts +
                ", detail='" + detail + '\'' +
                '}';
    }
}


3.实现dao层

  1. 在项目的java目录下新建dao包,编写dao层接口BookDao即可,代码如下所示:
package dao;

import org.apache.ibatis.annotations.Param;
import pojo.Book;

import java.util.List;

public interface BookDao {

    //增加一个Books
    int addBook(Book books);

    //根据id删除Books
    int deleteBookByID(@Param("bookID") int id);

    //更新Books
    int updateBook(Book books);

    //根据id查询Book
    Book queryBookByID(@Param("bookID") int id);

    //查看全部的Book
    List<Book> queryAllBook();

}
  1. 在Maven中导入Mybatis所需要的驱动包(mybatis),代码如下:
    
    <dependency>
      <groupId>org.mybatisgroupId>
      <artifactId>mybatisartifactId>
      <version>3.4.6version>
    dependency>
  1. 在dao包下编写对应的映射文件BookMapper.xml,代码如下:



<mapper namespace="dao.BookDao">
    
    <insert id="addBook" parameterType="Book">
        insert into ssmbuild.books(bookID , bookName, bookCounts, detail)
        values (#{bookID},#{bookName},#{bookCounts},#{detail})
    insert>

    
    <delete id="deleteBookByID" parameterType="int">
        delete from ssmbuild.books where bookID = #{bookID}
    delete>

    
    <update id="updateBook" parameterType="Book">
        update ssmbuild.books
        set bookName = #{bookName} , bookCounts = #{bookCounts} ,detail = #{detail}
        where bookID = #{bookID}
    update>

    
    <select id="queryBookByID" resultType="Book">
        select * from ssmbuild.books where bookID = #{bookID}
    select>

    
    <select id="queryAllBook" resultType="Book">
        select * from ssmbuild.books
    select>

mapper>
  1. 在resources目录下编写Mybatis的配置文件Mybatis-config.xml,用于配置别名,以及注册映射文件,代码如下:


<configuration>

    <typeAliases>
        <package name="pojo"/>
    typeAliases>

    <mappers>
        <mapper resource="dao/BookMapper.xml">mapper>
    mappers>


configuration>


4.实现service层

  1. 在项目的java目录下新建service包,编写service层接口BookService,代码如下所示:
package service;

import org.apache.ibatis.annotations.Param;
import pojo.Book;

import java.util.List;

public interface BookService {

    //增加一个Books
    int addBook(Book books);

    //根据id删除Books
    int deleteBookByID( @Param("bookID") int id);

    //更新Books
    int updateBook(Book books);

    //根据id查询Book
    Book queryBookByID(@Param("bookID") int id);

    //查看全部的Book
    List<Book> queryAllBook();

}

  1. 在service包下编写对应的实现类BookServiceImpl,代码如下:
package service;

import dao.BookDao;
import pojo.Book;

import java.util.List;

public class BookServiceImpl implements BookService{

    // 组合
    private BookDao bookDao;

    public void setBookDao(BookDao bookDao) {
        this.bookDao = bookDao;
    }


    @Override
    public int addBook(Book books) {
        return bookDao.addBook(books);
    }

    @Override
    public int deleteBookByID(int id) {
        return bookDao.deleteBookByID(id);
    }

    @Override
    public int updateBook(Book books) {
        return bookDao.updateBook(books);
    }

    @Override
    public Book queryBookByID(int id) {
        return bookDao.queryBookByID(id);
    }

    @Override
    public List<Book> queryAllBook() {
        return bookDao.queryAllBook();
    }
}


5.配置Spring整合dao层

  1. 在本例中使用c3p0连接池,需要在Maven导入相关的包,代码如下:
    
    <dependency>
      <groupId>com.mchangegroupId>
      <artifactId>c3p0artifactId>
      <version>0.9.5.2version>
    dependency>
    
    <dependency>
      <groupId>org.mybatisgroupId>
      <artifactId>mybatis-springartifactId>
      <version>1.3.1version>
    dependency>
    
    <dependency>
      <groupId>org.springframeworkgroupId>
      <artifactId>spring-jdbcartifactId>
      <version>4.3.24.RELEASEversion>
    dependency>
    <dependency>
      <groupId>org.springframeworkgroupId>
      <artifactId>spring-webmvcartifactId>
      <version>4.3.24.RELEASEversion>
    dependency>
  1. 在resources目录下新建spring文件夹,并在该文件夹中新建一个名为spring-dao.xml的配置文件,用于让Spring整合mybatis,代码如下:

<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/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">

    
    
    <context:property-placeholder location="classpath:database.properties"/>

    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        
        <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>

    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    bean>

    
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        
        <property name="basePackage" value="dao"/>
    bean>

    
    <context:component-scan base-package="dao"/>

beans>

6.配置Spring整合service层

在resources/spring文件夹中新建一个名为spring-service.xml的配置文件,用于让Spring整合service层,代码如下:


<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/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">

    
    <context:component-scan base-package="service"/>

    
    <bean id="bookServiceImpl" class="service.BookServiceImpl">
        <property name="bookDao" ref="bookDao"/>
    bean>

    
    <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        
        <property name="dataSource" ref="dataSource"/>
    bean>


beans>

7.配置Spring整合Spring MVC

  1. 修改webapp目录下的web.xml文件,代码如下:

<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/javaee
         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         id="WebApp_ID" version="3.0">

  filter>
  <filter-mapping>
    <filter-name>encodingFilterfilter-name>
    <url-pattern>/*url-pattern>
  filter-mapping>

web-app>
  1. 在resources/spring文件夹中新建一个名为spring-mvc.xml的配置文件,用于让Spring整合servlet层,代码如下:

<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"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    
    <context:component-scan base-package="controller"/>

    
    <mvc:default-servlet-handler/>

    
    <mvc:annotation-driven/>

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>

beans>
  1. 在目录中新建一个名为filter的包,在包中新建名为GenericEncodingFilter的类,用于字符编码过滤,代码如下:
package filter;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.Map;

/**
 * 解决get和post请求 全部乱码的过滤器
 */
public class GenericEncodingFilter implements Filter {

    @Override
    public void destroy() {
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        //处理response的字符编码
        HttpServletResponse myResponse=(HttpServletResponse) response;
        myResponse.setContentType("text/html;charset=UTF-8");

        // 转型为与协议相关对象
        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        // 对request包装增强
        HttpServletRequest myrequest = new MyRequest(httpServletRequest);

        chain.doFilter(myrequest, response);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

}

//自定义request对象,HttpServletRequest的包装类
class MyRequest extends HttpServletRequestWrapper {

    private HttpServletRequest request;
    //是否编码的标记
    private boolean hasEncode;
    //定义一个可以传入HttpServletRequest对象的构造函数,以便对其进行装饰
    public MyRequest(HttpServletRequest request) {
        super(request);// super必须写
        this.request = request;
    }

    // 对需要增强方法 进行覆盖
    @Override
    public Map getParameterMap() {
        // 先获得请求方式
        String method = request.getMethod();
        if (method.equalsIgnoreCase("post")) {
            // post请求
            try {
                // 处理post乱码
                request.setCharacterEncoding("utf-8");
                return request.getParameterMap();
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
        } else if (method.equalsIgnoreCase("get")) {
            // get请求
            Map<String, String[]> parameterMap = request.getParameterMap();
            if (!hasEncode) { // 确保get手动编码逻辑只运行一次
                for (String parameterName : parameterMap.keySet()) {
                    String[] values = parameterMap.get(parameterName);
                    if (values != null) {
                        for (int i = 0; i < values.length; i++) {
                            try {
                                // 处理get乱码
                                values[i] = new String(values[i]
                                        .getBytes("ISO-8859-1"), "utf-8");
                            } catch (UnsupportedEncodingException e) {
                                e.printStackTrace();
                            }
                        }
                    }
                }
                hasEncode = true;
            }
            return parameterMap;
        }
        return super.getParameterMap();
    }

    //取一个值
    @Override
    public String getParameter(String name) {
        Map<String, String[]> parameterMap = getParameterMap();
        String[] values = parameterMap.get(name);
        if (values == null) {
            return null;
        }
        return values[0]; // 取回参数的第一个值
    }

    //取所有值
    @Override
    public String[] getParameterValues(String name) {
        Map<String, String[]> parameterMap = getParameterMap();
        String[] values = parameterMap.get(name);
        return values;
    }
}


8.配置Spring整合文件

  1. 在resources中新建一个名为applicationContext.xml的配置文件,用于整合上面的spring-dao.xml、spring-service.xml、spring-mvc.xml,代码如下:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd">
    
    
    <import resource="classpath:spring/spring-dao.xml"/>
    <import resource="classpath:spring/spring-service.xml"/>
    <import resource="classpath:spring/spring-mvc.xml"/>

beans>
  1. 在Maven导入jsp和servlet的包,代码如下:
   <dependency>
      <groupId>javax.servletgroupId>
      <artifactId>javax.servlet-apiartifactId>
      <version>3.0.1version>
      <scope>providedscope>
    dependency>
    <dependency>
      <groupId>javax.servlet.jspgroupId>
      <artifactId>jsp-apiartifactId>
      <version>2.2version>
      <scope>providedscope>
    dependency>
    <dependency>
      <groupId>javax.servletgroupId>
      <artifactId>jstlartifactId>
      <version>1.2version>
    dependency>

9.实现controller层

在项目的java目录下新建controller包,编写控制器BookController,代码如下所示:

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;

    // 展示全部的书籍
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Book> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    }

    // 跳转到新增书籍页面
    @RequestMapping("/toAddBook")
    public String toAddBookPage(){
        return "addBook";
    }

    // 增加书籍
    @RequestMapping("/addBook")
    public String addBook(Book book){
        bookService.addBook(book);
        return "redirect:/book/allBook";
    }

    // 跳转到修改书籍页面
    @RequestMapping("/toUpdateBook")
    public String toUpdateBook(int id,Model model){
        Book book = bookService.queryBookByID(id);
        model.addAttribute("book",book);
        return "updateBook";
    }

    // 修改书籍
    @RequestMapping("/updateBook")
    public String updateBook(Book book,Model model){
        bookService.updateBook(book);
        // 更新最新的书籍
        Book book1 = bookService.queryBookByID(book.getBookID());
        model.addAttribute("books",book1);
        return "redirect:/book/allBook";
    }

    // 删除书籍,使用Restful风格
    @RequestMapping("/del/{bookID}")
    public String delete(@PathVariable("bookID") int id){
        bookService.deleteBookByID(id);
        return "redirect:/book/allBook";
    }
}


10.实现view层

  1. 编写主页index.jsp,用于进入查看所有图书的页面,代码如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>

<html>
<head>
    <title>首页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">点击进入列表页a>
h3>

运行

配置好Tomcat运行环境后,即可开始运行,结果图如下:

  1. 首页(index.jsp)
    SSM项目实例——简易版图书管理系统_第2张图片
  2. 显示全部书籍(allBook.jsp)
    SSM项目实例——简易版图书管理系统_第3张图片
  3. 增加书籍页面(addBook.jsp)
    SSM项目实例——简易版图书管理系统_第4张图片
  4. 修改书籍页面(updateBook.jsp)
    SSM项目实例——简易版图书管理系统_第5张图片

后记

尽管现在的Java Web项目的开发多用Spring Boot进行搭建,但是使用相对原生的SSM(Spring + Spring MVC + Mybatis)进行开发,不仅能让我们对于Web项目的搭建流程更加熟悉,还会对我们在日后的学习和工作中大有裨益
项目的源码地址:SSM版本 简易管理系统,由于该博客之前有一些细节错误尚未修正,这里在搭建项目的时候进行了部分修改。对按照该博客搭建项目后遇到坑的读者表示抱歉,感谢您的浏览!
