            </resource>
        </resources>
    </build>
```

## 建立基本结构和配置框架

com.zwt.pojo

com.zwt.dao

com.zwt.service

com.zwt.controller

mybatis-config.xml

```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
<?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>
```



## Mybatis层编写

数据库配置文件 database.properties


Mybatis层编写
1、数据库配置文件 database.properties

```properties
jdbc.driver=com.mysql.jdbc.Driver
#如果使用的是MySql8.0+，增加一个时区的配置； &serverTimezone=Asia/shagnhai
jdbc.url=jdbc:mysql://localhost:3306/mybatis?useSSL=false&useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
jdbc.username=root
jdbc.password= 
```


编写MyBatis的核心配置文件

```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>
<!--配置数据源，整合后交给spring去做-->

<!--起别名-->
    <settings>
        <setting name="logImpl" value="STDOUT_lOGGING"/>
    </settings>
    <typeAliases>
        <package name="com.zwt.pojo"/>
    </typeAliases>

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

</configuration>
```


编写数据库对应的实体类 com.zwt.pojo.Books

```java
package com.zwt.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;
}
```

编写Dao层的 Mapper接口！

```Java
package com.zwt.dao;

import com.zwt.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 id);
    //修改一本书
    int updateBook(Books books);
    //查找一本书
    Books queryBookById(int id);
    //查找所有书
    List<Books> queryAllBook();
    //新增搜索框功能
    Books queryBookByName(String bookName);
}
```

编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包；

```xml
<?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.zwt.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=#{bookName}
    </select>

</mapper>

```

编写Service层的接口和实现类

接口：

```java
package com.zwt.service;

import com.zwt.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 id);
    //修改一本书
    int updateBook(Books books);
    //查找一本书
    Books queryBookById(int id);
    //查找所有书
    List<Books> queryAllBook();

    //新增搜索框功能
    Books queryBookByName(String bookName);
}


```

实现类：

```java
package com.zwt.service;

import com.zwt.dao.BookMapper;
import com.zwt.pojo.Books;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service
public class BookServiceImpl implements BookService{
    //service调dao层：组合Dao
    @Autowired
    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);
    }


}
```



## Spring层

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；
2、编写Spring整合Mybatis的相关的配置文件；spring-dao.xml

```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">

    <!--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（自动化的加载配置文件，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="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${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、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>
    <!--4、配置dao接口扫描包，动态的实现了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dao包-->
        <property name="basePackage" value="com.zwt.dao"/>
    </bean>

</beans>
```

## Spring整合service层

```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: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.zwt.service"/>
    
    <!--2、将我们的所有业务类，注入到Spring，可以通过配置，或者注解实现-->
    <bean id="BookServiceImpl" class="com.zwt.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>
    <!--3、声明式事务配置-->
    <bean id="transactionManage" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--4、aop事务支持-->
    <!--结合AOP实现事务的织入-->
    <!--配置事务的通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManage">
        <!--给哪些方法配置事务-->
        <!--配置事务的传播特性-->
        <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.zwt.dao.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>

</beans>
```

Spring就是一个大杂烩，一个容器！

## SpringMVC层

web.xml

```xml
<?xml version="1.0" encoding="UTF-8"?>

    </bean>

</beans>
```

Spring配置整合文件，applicationContext.xml

```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"

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

</beans>
```

## Controller 和 视图层编写

BookController 类编写 ， 方法一：查询全部书籍

```java
@Controller
//@RequestMapping("/book")
public class BookController {
    //controller调service层
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    //查询全部的书籍，并且返回到一个书籍展示页面
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    
    }
}
```

编写首页 index.jsp

```html


<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>

  <head>
    <title>首页</title>
    <style>
      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:5px;
      }
    </style>
  </head>

  <body>




  <h3>
    <a href="${pageContext.request.contextPath}/allBook">点击进入列表页</a>
  </h3>

  </body>
</html>
```
