--------------------

# 一 基本环境 #

1 基本POM依赖

<dependencies>
       
       <dependency>
           <groupId>junit</groupId>
           <artifactId>junit</artifactId>

           <artifactId>c3p0</artifactId>
           <version>0.9.5.2</version>
       </dependency>
       
       <dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>servlet-api</artifactId>
           <version>2.5</version>
       </dependency>
       <dependency>
           <groupId>javax.servlet.jsp</groupId>
           <artifactId>jsp-api</artifactId>
           <version>2.2</version>
       </dependency>
       <dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>jstl</artifactId>
           <version>1.2</version>
       </dependency>
       
       <dependency>
           <groupId>org.mybatis</groupId>
           <artifactId>mybatis</artifactId>
           <version>3.5.2</version>
       </dependency>
       <dependency>
           <groupId>org.mybatis</groupId>
           <artifactId>mybatis-spring</artifactId>
           <version>2.0.2</version>
       </dependency>
       
       <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-webmvc</artifactId>
           <version>5.1.9.RELEASE</version>
       </dependency>
       <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-jdbc</artifactId>
           <version>5.1.9.RELEASE</version>
       </dependency>
    </dependencies>

2 Maven资源过滤设置，防止找不到配置文件

<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>

# 二 Mybatis层  #

1 数据库配置文件 **database.properties**

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/testdb?useSSL=true&useUnicode=true&characterEncoding=utf8
    jdbc.username=root
    jdbc.password=123456

2 Mybatis核心配置文件 **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>
       <typeAliases>
           <package name="com.cakin.pojo"/>
       </typeAliases>
       <mappers>
           <mapper resource="com/cakin/dao/BookMapper.xml"/>
       </mappers>
    </configuration>

3 编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包。

<?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="com.cakin.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>
    </mapper>

# 三 spring层 #

1  Spring整合MyBatis，配置文件为  **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">
       
       
       <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}"/>
           
           <property name="maxPoolSize" value="30"/>
           <property name="minPoolSize" value="10"/>
           
           <property name="autoCommitOnClose" value="false"/>
           
           <property name="checkoutTimeout" value="10000"/>
           
           <property name="acquireRetryAttempts" value="2"/>
       </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="com.cakin.dao"/>
       </bean>
    </beans>

2 Spring整合service层，配置文件为：**spring-service.xml**

# 四 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">
       
       <servlet>
           <servlet-name>DispatcherServlet</servlet-name>
           <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
           <init-param>
               <param-name>contextConfigLocation</param-name>
                 
               <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>
       
       <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-config>
           <session-timeout>15</session-timeout>
       </session-config>
    </web-app>

2 核心配置文件：**spring-mvc.xml**

# 五 所有配置文件整合到spring：**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>
