1、环境准备

1.1、新建一Maven项目！ssmbuild ，添加web的支持

1.2、导入相关的pom依赖！

<!-- 依赖 -->
<dependencies>
 <!-- Junit-->
 <dependency>
     <groupId>junit</groupId>
     <artifactId>junit</artifactId>
     <version>4.13.2</version>

 <dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-jdbc</artifactId>
     <version>5.3.9</version>
 </dependency>

</dependencies>

1.3、maven静态资源导出问题

<!-- Maven资源过滤设置 -->
<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

1.4、建立基本结构和配置框架

com.badwei.pojo
com.badwei.dao
com.badwei.service
com.badwei.controller

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

applicationContext.xml

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

</beans>

2、Mybatis层编写

2.1、数据库配置文件 database.properties

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

2.2、IDEA关联数据库

没有出现自动补全sql提示的话：在settings-->Languages &Frameworks-->SQL Dialects中配置数据库类型，将项目添加进来，配置完成后Apply-OK

2.3、编写MyBatis的核心配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    
    <!-- 配置数据源，交给Spring去做 -->

    <typeAliases>
        <package name="com.badwei.pojo"/>
    </typeAliases>

<!--    绑定Mapper-->
    <mappers>
        <mapper class="com.badwei.dao.BookMapper" />
    </mappers>

</configuration>

2.4、编写数据库对应的实体类 nuc.ss.pojo.Books（使用lombok插件！）

package com.badwei.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

2.5、编写Dao层的 Mapper接口！BookMapper.java

package com.badwei.dao;

import com.badwei.pojo.Books;

import java.util.List;

public interface BookMapper {

    //增加一本书
    int addBook(Books books);
    //删除一本书
    int deleteBookById(int bookID);
    //更新一本书
    int updateBook(Books books);
    //查询一本书
    Books selectBookById(int bookID);
    //查询全部的书
    List<Books> selectAllBook();
}

2.6、写接口对应的 Mapper.xml 文件。需要导入MyBatis的包；BookMapper.xml

写完Mapper和Mapper.xml后，要记得在mybatis-config.xml中绑定

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.badwei.dao.BookMapper">

    <insert id="addBook" parameterType="Books">
        insert into ssmbuild.books (bookName, bookCounts, detail)
        values (#{bookName},#{bookCounts},#{detail});
    </insert>

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

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

    <select id="selectBookById" parameterType="int" resultType="Books">
        select * from ssmbuild.books
        where bookID = #{bookID};
    </select>

    <select id="selectAllBook" resultType="Books">
        select * from ssmbuild.books;
    </select>


</mapper>

2.7、编写Service层的接口BookService和实现类BookServiceImpl

package com.badwei.service;

import com.badwei.pojo.Books;

import java.util.List;

public interface BookService {
    //增加一本书
    int addBook(Books books);
    //删除一本书
    int deleteBookById(int bookID);
    //更新一本书
    int updateBook(Books books);
    //查询一本书
    Books selectBookById(int bookID);
    //查询全部的书
    List<Books> selectAllBook();
}

package com.badwei.service;

import com.badwei.dao.BookMapper;
import com.badwei.pojo.Books;

import java.util.List;

public class BookServiceImpl implements BookService{

    private BookMapper bookMapper;//Service要调用dao层，所以提供dao和set,set为了方便注入
    public BookServiceImpl(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    @Override
    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    @Override
    public int deleteBookById(int bookID) {
        return bookMapper.deleteBookById(bookID);
    }

    @Override
    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    @Override
    public Books selectBookById(int bookID) {
        return bookMapper.selectBookById(bookID);
    }

    @Override
    public List<Books> selectAllBook() {
        return bookMapper.selectAllBook();
    }
}

OK，到此，底层需求操作编写完毕！

3、Spring层

3.1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；

3.2、我们去编写Spring整合Mybatis的相关的配置文件；spring-dao.xml

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

    <!-- 配置整合mybatis -->
    <!-- 1.关联数据库文件 -->
    <context:property-placeholder location="classpath:database.properties"/>

    <!-- 2.数据库连接池 -->
    <!--数据库连接池
        dbcp 半自动化操作 不能自动连接
        c3p0 自动化操作（自动的加载配置文件 并且设置到对象里面）
        druid
        hikari
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>

        <!-- c3p0连接池的私有属性 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

    <!-- 3.配置SqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 -->
    <!--解释 ：https://www.cnblogs.com/jpfss/p/7799806.html-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.badwei.dao"/>
    </bean>

</beans>

3.3、Spring整合service层,spring-service.xml

<?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/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">

    <!-- 扫描service相关的bean -->
    <context:component-scan base-package="com.badwei.service" />

    <!--BookServiceImpl注入到Spring IOC容器中,也可以通过配置，或注解@Service和@Autowired实现-->
    <bean id="BookServiceImpl" class="com.badwei.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!-- 配置事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>

</beans>

4、SpringMVC层

4.1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <!--DispatcherServlet-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!--一定要注意:我们这里加载的是总的配置文件，之前被这里坑了！-->
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--encodingFilter-->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <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>

    <!--Session过期时间-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

</web-app>

4.2、spring-mvc.xml

<?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"
       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
   https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 配置SpringMVC -->
    <!-- 1.开启SpringMVC注解驱动 -->
    <mvc:annotation-driven />
    <!-- 2.静态资源默认servlet配置-->
    <mvc:default-servlet-handler/>

    <!-- 3.配置jsp 显示ViewResolver视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <!-- 4.扫描web相关的bean -->
    <context:component-scan base-package="com.badwei.controller" />

</beans>

4.3、Spring配置整合文件，applicationContext.xml

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

    <import resource="classpath:spring-dao.xml" />
    <import resource="classpath:spring-service.xml" />
    <import resource="classpath:spring-mvc.xml" />

</beans>

配置文件，暂时结束！

5、Controller 和视图层编写（增删改查）

5.1、BookController 类编写，方法一：查询全部书籍

@Controller
@RequestMapping("/book")
public class BookController {

    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    @RequestMapping("/allBook")
    public String list(Model model) {
        List<Books> list = bookService.selectAllBook();
        model.addAttribute("list", list);
        return "allBook";
    }

}

5.2、编写首页index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE HTML>
<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>
</body>
</html>

5.3、书籍列表页面allBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
   <title>书籍列表</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>书籍列表 —— 显示所有书籍</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>书籍编号</th>
                   <th>书籍名字</th>
                   <th>书籍数量</th>
                   <th>书籍详情</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()}">删除</a>
                       </td>
                   </tr>
               </c:forEach>
               </tbody>
           </table>
       </div>
   </div>
</div>

5.4BookController 类新增方法，方法二：添加书籍

@RequestMapping("/toAddBook")
public String toAddPaper() {
    return "addBook";
}

@RequestMapping("/addBook")
public String addPaper(Books books) {
    System.out.println(books);
    bookService.addBook(books);
    return "redirect:/book/allBook";
}

5.5、添加书籍页面：addBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>
<head>
   <title>新增书籍</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>新增书籍</small>
               </h1>
           </div>
       </div>
   </div>
   <form action="${pageContext.request.contextPath}/book/addBook" method="post">
      书籍名称：<input type="text" name="bookName"><br><br><br>
      书籍数量：<input type="text" name="bookCounts"><br><br><br>
      书籍详情：<input type="text" name="detail"><br><br><br>
       <input type="submit" value="添加">
   </form>

</div>

5.6、BookController 类新增方法，方法三：修改书籍

@RequestMapping("/toUpdateBook")
public String toUpdateBook(Model model, int id) {
    Books books = bookService.selectBookById(id);
    System.out.println(books);
    model.addAttribute("book",books );
    return "updateBook";
}

@RequestMapping("/updateBook")
public String updateBook(Books book) {
    System.out.println(book);
    bookService.updateBook(book);
    return "redirect:/book/allBook";
}

5.7、修改书籍页面 updateBook.jsp

<%@ 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()}"/><!--隐藏域-->
      书籍名称：<input type="text" name="bookName" value="${book.getBookName()}"/>
      书籍数量：<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>
      书籍详情：<input type="text" name="detail" value="${book.getDetail() }"/>
       <input type="submit" value="提交"/>
   </form>

</div>

5.8、BookController 类编写，方法四：删除书籍

@RequestMapping("/del/{bookId}")
public String deleteBook(@PathVariable("bookID") int bookID) {
    bookService.deleteBookById(bookID);
    return "redirect:/book/allBook";
}

6、新增查询功能

6.1、allBook.jsp新增查询按钮

<%--查询书籍功能--%>
<div class="col-md-4 column">
    <form action="${pageContext.request.contextPath}/book/selectBookByName" method="post" style="float: right" class="form-inline">
        <span style="color: red;font-weight: bold">${error}</span>
        <input type="text" name="selectBookName" class="form-control" placeholder="请输入要查询的书籍名称" required>
        <input type="submit" value="查询" class="btn btn-primary">
    </form>
</div>

6.2、dao层BookMapper.java 新增查询接口

Books selectBookByName(String bookName);

BookMapper.xml

<select id="selectBookByName" parameterType="string" resultType="Books">
    select * from ssmbuild.books
    where bookName = #{bookName};
</select>

6.3、Service层的BookService.java 新增查询接口

Books selectBookByName(String bookName);

BookServiceImpl.java实现

@Override
public Books selectBookByName(String bookName) {
    return bookMapper.selectBookByName(bookName);
}

6.4、Controller层BookController.java新增查询请求

@RequestMapping("/selectBookByName")
public String selectBookName(String selectBookName,Model model){
    Books books = bookService.selectBookByName(selectBookName);
    List<Books> list = new ArrayList<>();
    if (books==null){
        model.addAttribute("error","未查到");
    }else{
        list.add(books);
    }

    System.out.println(list.toString());
    model.addAttribute("list", list);
    return "allBook";
}

完成
