数据库

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');

完善项目文件结构

在这里插入图片描述

整合Mybatis

增加mybatis配置文件`mybatis-config.xml`

这里不配置数据源，后面Spring来配置

<?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>

    <typeAliases>
        <package name="org.dam.pojo"/>
    </typeAliases>
    <mappers>
        <mapper resource="org/dam/dao/xml/BookMapper.xml"/>
    </mappers>

</configuration>

pojo 实体类

实体类的字段和数据表的属性一一对应

package org.dam.pojo;

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

/**
 * @Author dam
 * @create 2024/1/14 18:58
 */
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {

    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
    
}

dao层操作数据库

mapper接口

mapper接口负责定义一些数据库的基本操作接口

package org.dam.dao;

import org.dam.pojo.Books;

import java.util.List;

/**
 * @Author dam
 * @create 2024/1/14 19:01
 */
public interface BookMapper {

    /**
     * 增加一个Book
     * @param book
     * @return
     */
    int addBook(Books book);

    /**
     * 根据id删除一个Book
     * @param id
     * @return
     */
    int deleteBookById(int id);

    /**
     * 更新Book
     * @param books
     * @return
     */
    int updateBook(Books books);

    /**
     * 根据id查询,返回一个Book
     * @param id
     * @return
     */
    Books queryBookById(int id);

    /**
     * 查询全部Book,返回list集合
     * @return
     */
    List<Books> queryAllBook();

}

xml

xml文件实现 mapper接口，为每个接口实现相应的sql操作

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

<mapper namespace="org.dam.dao.BookMapper">

    <!--增加一个Book-->
    <insert id="addBook" parameterType="Books">
        insert into books(bookName,bookCounts,detail)
        values (#{bookName}, #{bookCounts}, #{detail})
    </insert>

    <!--根据id删除一个Book-->
    <delete id="deleteBookById" parameterType="int">
        delete from books where bookID=#{bookID}
    </delete>

    <!--更新Book-->
    <update id="updateBook" parameterType="Books">
        update books
        set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
        where bookID = #{bookID}
    </update>

    <!--根据id查询,返回一个Book-->
    <select id="queryBookById" resultType="Books">
        select * from books
        where bookID = #{bookID}
    </select>

    <!--查询全部Book-->
    <select id="queryAllBook" resultType="Books">
        SELECT * from books
    </select>

</mapper>

service层实现业务相关操作

业务接口

package org.dam.service;

import org.dam.pojo.Books;

import java.util.List;

/**
 * @Author dam
 * @create 2024/1/14 19:02
 */
public interface BookService {
    /**
     * 增加一个Book
     * @param book
     * @return
     */
    int addBook(Books book);

    /**
     * 根据id删除一个Book
     * @param id
     * @return
     */
    int deleteBookById(int id);

    /**
     * 更新Book
     * @param books
     * @return
     */
    int updateBook(Books books);

    /**
     * 根据id查询,返回一个Book
     * @param id
     * @return
     */
    Books queryBookById(int id);

    /**
     * 查询全部Book,返回list集合
     * @return
     */
    List<Books> queryAllBook();
}

业务接口实现

接口实现类负责调用 dao层定义的数据库操作方法，并添加一些其他逻辑

package org.dam.service.impl;

import org.dam.dao.BookMapper;
import org.dam.pojo.Books;
import org.dam.service.BookService;

import java.util.List;

/**
 * @Author dam
 * @create 2024/1/14 19:03
 */
public class BookServiceImpl implements BookService {

    //调用dao层的操作，设置一个set接口，方便Spring管理
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

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

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

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

    @Override
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

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

项目结构

整合Mybatis之后的项目结构如下：

在这里插入图片描述

整合Spring

数据库连接配置 database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=12345678

数据连接配置 spring-dao.xml

整合Mybatis，配置数据库连接信息

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

    <!-- 2.数据库连接池 -->
    <!--数据库连接池

        c3p0 自动化操作（自动的加载配置文件 并且设置到对象里面）
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}"/>

        <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"/>

        <!-- 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="org.dam.dao"/>
    </bean>

</beans>

spring配置 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"

        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>

</beans>

项目结构

在这里插入图片描述

整合SpringMVC

web.xml

不要直接使用下面的代码，继续往下面看

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

    </filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>utf-8</param-value>
    </init-param>

  </filter-mapping>

    <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>

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

</web-app>

出现下面的情况，是因为idea自动添加的web.xml中的jsp页面头约束版本太低

在这里插入图片描述

解决方法，将第一种头文件修改成第二种即可

第一种头约束

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
</web-app>

第二种头约束

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
</web-app>

即改成下面的方式

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <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="org.dam.controller" />

</beans>

记住，还需要在applicationContext.xml中引入spring-mvc.xml配置

<import resource="spring-mvc.xml"/>

如下图所示
