前言

新建一個普通的Maven項目

基本目錄結構

├── src                   	# 
│   ├── main               	# 
│   │	└── java           	# java代碼目錄
│   │	└── resources       # 配置文件目錄, 存放下面Spring配置文件
│   ├── test           		# 單元測試目錄
├── web                   	# web目錄
│   └── WEB-INF           	# web.xml 配置文件目錄


1. Mybatis層編寫

1、在 resources 目錄下新建數據庫配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver
# 如果是使用 MySQL8.0+ 那么還需要增加一個時區的配置; serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

2、在 resources 目錄下創建Mybatis配置文件 mybatis-config.xml



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

    
    <mappers>
        <mapper class="com.pro.dao.BooksMapper"/>
    mappers>

configuration>


2. Spring層編寫

1. Spring整合Mybatis

  1. 配置Spring整合MyBatis，這里數據源使用c3p0連接池；

  2. 編寫Spring整合Mybatis的相關的配置文件；在 resources 目錄下創建 spring-dao.xml

注意：這里要引入上面Mybatis層的兩個配置文件，配置文件的名稱不要寫錯


<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">

    
    <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.pro.dao"/>
    bean>
beans>

2. Spring整合service

將業務層的類注入到Spring中，在 resources 目錄下創建 spring-service.xml


<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd">

    
    <context:component-scan base-package="com.pro.service"/>

    
    <bean id="BooksServiceImpl" class="com.pro.service.BooksServiceImpl">
        <property name="booksMapper" ref="booksMapper"/>
    bean>

    
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        
        <property name="dataSource" ref="dataSource"/>
    bean>

    
    
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        
        
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        tx:attributes>
    tx:advice>

    
    <aop:config>
        
        <aop:pointcut id="txPointCut" expression="execution(* com.pro.dao.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    aop:config>
beans>


3. SpringMVC層編寫

1. 編寫web.xml

修改 WEB-INF 下的 web.xml 文件

這里引入Spring整合的配置文件 applicationContext.xml


<web-app xmlns="https://jakarta.ee/xml/ns/jakartaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee https://jakarta.ee/xml/ns/jakartaee/web-app_5_0.xsd"
         version="5.0">

    
    <servlet>
        <servlet-name>springmvcservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        
        <init-param>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:applicationContext.xmlparam-value>
        init-param>
        
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>springmvcservlet-name>
        <url-pattern>/url-pattern>
    servlet-mapping>

    
    <filter>
        <filter-name>encodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>utf-8param-value>
        init-param>
    filter>
    <filter-mapping>
        <filter-name>encodingFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

    
    <session-config>
        <session-timeout>15session-timeout>
    session-config>
web-app>

2. 編寫spring-mvc.xml

在 resources 目錄下創建 spring-mvc.xml


<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       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/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">


    
    <mvc:annotation-driven/>
    
    <mvc:default-servlet-handler/>
    
    <context:component-scan base-package="com.pro.controller"/>
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>

beans>


4. Spring配置整合文件，applicationContext.xml

在 resources 目錄下創建 applicationContext.xml

這里引入上面三個配置文件 spring-dao.xml、spring-service.xml、spring-mvc.xml 整合成一個總的配置文件


<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>
