    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>

            </includes>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

2.创建实体类

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

    public Books(String bookName, int bookCounts, String detail) {
        this.bookName = bookName;
        this.bookCounts = bookCounts;
        this.detail = detail;
    }
}

3.编写dao层

1.BookMapper

import com.zh.pojo.Books;
import com.zh.service.ServiceImpl;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.util.List;
import java.util.logging.Logger;



public class test {

    @Test
    public void test1(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        ServiceImpl service = context.getBean("BookServiceImpl", ServiceImpl.class);
        Books books = service.queryBookById(3);
        System.out.println(books);
    }
}

2.BookMapper.xml

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zh.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=#{bookCounts},detail=#{detail}
        where bookID=#{bookID}
    </update>

    <select id="queryBookById" resultType="Books">
select *from ssmbuild.books where bookID=#{bookId}
    </select>

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

    <select id="queryBookByName" resultType="Books">
    <!--select*from ssmbuild.books where bookName like concat('%',#{bookName,jdbcType=VARCHAR},'%');-->
select *from ssmbuild.books where bookName=#{bookName}

    </select>
</mapper>

4.编写service层

1.service

public interface Service {

    //增加一本书
    int addBook(Books books);

    //删除一本书
    int deleteBookById(int id);

    //更新一本书
    int updateBook(Books books);

    //查询一本书
    Books queryBookById(int id);

    //查询所有书
    List<Books> queryAllBook();

    Books queryBookByName(String bookName);
}

2.serviceImpl

public class ServiceImpl implements Service{
    //service调dao层：组合dao
    private BookMapper bookMapper;

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

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

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

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

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

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

    public Books queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }
}

5.mybatis-config

<?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>
    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>
    <typeAliases>
    <package name="com.zh.pojo"/>
</typeAliases>

    <mappers>
        <mapper class="com.zh.dao.BookMapper"/>
    </mappers>
</configuration>

二.Spring整合Mybatis

1.Spring-dao

<?xml version="1.0" encoding="utf8"?>
<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">
    <context:property-placeholder location="classpath:database.properties"/>
    <!--1.关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>

    <!--2.连接池
    dbcp:半自动化操作，不能自动连接
    c3p0:自动化操作(自动化的加载配置问价，并且可以自动设置到对象中)
    druid:hikari
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="password" value="${jdbc.pwd}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <!--c3p0连接池的自由属性-->
        <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.sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--绑定mybatis的配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!--配置dao接口扫描包，动态的实现类Dao接口可以注入到Spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!--要扫描的包-->
        <property name="basePackage" value="com.zh.dao"/>
    </bean>
</beans>

2.Spring-service

<?xml version="1.0" encoding="utf8"?>
<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:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       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 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--1.扫描service下的包-->
    <context:component-scan base-package="com.zh.service"/>

    <!--2.将我们所有的业务类，注入到Spring，可以通过配置，或者注解实现-->
    <bean id="BookServiceImpl" class="com.zh.service.ServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!--3.声明式事务配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--4.aop事务支持-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <!--给哪些方法配置事务-->
        <!--配置事务的传播特性  new propagation-->
      <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
<!--配置事务的切入-->
    <aop:config>
        <aop:pointcut id="txPointCut" expression="execution(* com.zh.dao.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>

</beans>

三.SpringMvc层

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>

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 -->
   <beanclass="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.kuang.controller" />

</beans>

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

配置文件，暂时结束！Controller 和 视图层编写

四.controller和view层

1.Controller

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


    //controller调service
    @Autowired
    @Qualifier("BookServiceImpl")
    private Service service;


    //查询全部书籍。并返回一个书籍展示页面
    @RequestMapping("/allBook")
    public String list(Model model) {
        List<Books> list = service.queryAllBook();
        model.addAttribute("list", list);
        return "allBook";
    }

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

    //添加数据的请求
    @RequestMapping("/addBook")
    public String addBook(Books books) {
        System.out.println("addBook" + books);
        service.addBook(books);
        return "redirect:/book/allBook";
    }

    //跳转到修改页面
    @RequestMapping("/toUpdate")
    public String toUpDate(int id, Model model) {
        Books books = service.queryBookById(id);
        model.addAttribute("QBook", books);
        return "updateBook";
    }

    @RequestMapping("/updateBook")
    public String updateBook(Books books) {
        System.out.println("updateBook=>" + books);
        service.updateBook(books);

        return "redirect:/book/allBook";
    }

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

    @RequestMapping("/quaryByName")
    public String quaryByName(String queryBookName, Model model) {
        Books books = service.queryBookByName(queryBookName);
        System.out.println("queryBook=>" + books);
        List<Books> list = new ArrayList<Books>();
        list.add(books);
        if (books == null) {
            list = service.queryAllBook();
            model.addAttribute("error", "未查到");
        }
        model.addAttribute("list", list);
        return "allBook";
    }
}

2.view

1.主页(全部书籍)
