1.框架組成

Spring

SpringMVC

MyBatis

2.所需工具

Mysql 8.0.15

?數(shù)據(jù)庫管理系統(tǒng)，創(chuàng)建數(shù)據(jù)庫

Tomcat 8.5.51

?用于部署web項目

Maven 3.6.1

?項目構(gòu)建、項目依賴管理

lombok 1.18.10（可用可不用工具）

?用于類注解創(chuàng)建setter、getter、無參構(gòu)造、全參構(gòu)造、toString等函數(shù)

?注：只導(dǎo)入依賴，不安裝插件是不起作用的

3.搭建步驟

(1)新建一個空Maven項目，填寫項目相關(guān)信息，完成

(2)添加web框架支持

?選擇現(xiàn)有框架支持

(3)pom.xml導(dǎo)入依賴,設(shè)置Maven資源過濾

  <include>**/*.properties</include>
  <include>**/*.xml</include>
  </includes>
  <filtering>false</filtering>
 </resource>
 </resources>
</build>

(4)編寫MyBatis-config.xml（核心配置文件）

<?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>
 
 <!--設(shè)置運行日志-->
 <settings>
 <setting name="logImpl" value="STDOUT_LOGGING"/>
 </settings>
 
 <!--取別名-->
 <typeAliases>
 <package name="com.pojo"/>
 </typeAliases>
 
 <!--綁定mapper，根據(jù)自己的項目設(shè)置-->
 <mappers>
 <mapper resource="com/dao/Mapper.xml"/>
 </mappers>

</configuration>

(5)編寫database.properties（數(shù)據(jù)庫配置文件）

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/數(shù)據(jù)庫名?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=數(shù)據(jù)庫用戶名
jdbc.password=數(shù)據(jù)庫密碼

?根據(jù)自己的MySQL以及項目實際使用的數(shù)據(jù)庫來修改設(shè)置

?注：MySQL8.0以上驅(qū)動得使用com.mysql.cj.jdbc.Driver

(6)編寫Spring-dao.xml（Spring整合MyBatis配置文件）

<?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">

 <!-- 配置整合mybatis -->
 <!-- 1.關(guān)聯(lián)數(shù)據(jù)庫文件 -->
 <context:property-placeholder location="classpath:database.properties"/>

 <!-- 2.數(shù)據(jù)庫連接池 -->
 <!--數(shù)據(jù)庫連接池
 dbcp 半自動化操作 不能自動連接
 c3p0 自動化操作（自動的加載配置文件 并且設(shè)置到對象里面）
 -->
 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
 <!-- 配置連接池屬性 -->
 <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連接池的私有屬性 -->
 <property name="maxPoolSize" value="30"/>
 <property name="minPoolSize" value="10"/>
 <!-- 關(guān)閉連接后不自動commit -->
 <property name="autoCommitOnClose" value="false"/>
 <!-- 獲取連接超時時間 -->
 <property name="checkoutTimeout" value="10000"/>
 <!-- 當(dāng)獲取連接失敗重試次數(shù) -->
 <property name="acquireRetryAttempts" value="2"/>
 </bean>

 <!-- 3.配置SqlSessionFactory對象 -->
 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
 <!-- 注入數(shù)據(jù)庫連接池 -->
 <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.配置掃描Dao接口包，動態(tài)實現(xiàn)Dao接口注入到spring容器中 -->
 <!--解釋 ：https://www.cnblogs.com/jpfss/p/7799806.html-->
 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
 <!-- 注入sqlSessionFactory -->
 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
 <!-- 給出需要掃描Dao接口包 -->
 <property name="basePackage" value="com.dao"/>
 </bean>

</beans>

(7)編寫Spring-service.xml（Spring整合service層）

<?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
 http://www.springframework.org/schema/context/spring-context.xsd">

 <!-- 掃描service相關(guān)的bean -->
 <context:component-scan base-package="com.service" />

 <!--ServiceImpl注入到IOC容器中，此處需要修改成自己的-->
 <bean id="ServiceImpl" class="com.service.ServiceImpl">
 <property name="Mapper" ref="Mapper"/>
 </bean>

 <!-- 配置事務(wù)管理器 -->
 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
 <!-- 注入數(shù)據(jù)庫連接池 -->
 <property name="dataSource" ref="dataSource" />
 </bean>

</beans>

(8)修改web.xml文件

<?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:我們這里加載的是總的配置文件，之前被這里坑了！-->
  <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過期時間-->
 <session-config>
 <session-timeout>15</session-timeout>
 </session-config>
</web-app>

(9)編寫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.開啟SpringMVC注解驅(qū)動 -->
 <mvc:annotation-driven />
 <!-- 2.靜態(tài)資源默認(rèn)servlet配置-->
 <mvc:default-servlet-handler/>

 <!-- 3.配置jsp 顯示ViewResolver視圖解析器 -->
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
 <!--此處注意路徑問題,/WEB-INF/jsp/-->
 <property name="prefix" value="/WEB-INF/jsp/" />
 <property name="suffix" value=".jsp" />
 </bean>

 <!-- 4.掃描web相關(guān)的bean -->
 <context:component-scan base-package="com.controller" />
</beans>

(10)編寫applicationContext.xml（Spring配置整合文件）

<?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">

 <!--將Spring其他配置文件整合到一個總的配置文件，用的時候使用這個配置文件-->
 <import resource="classpath:Spring-service.xml"/>
 <import resource="classpath:Spring-dao.xml"/>
 <import resource="classpath:Spring-mvc.xml"/>

</beans>

(11)配置Tomcat

(12)檢查項目結(jié)構(gòu)（左上角 文件 -> 項目結(jié)構(gòu)）

(13)最后的項目文件結(jié)構(gòu)

?到了這里，框架已經(jīng)搭建完成

4.接口對應(yīng)的Mapper.xml

<?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">

<!--綁定對應(yīng)的接口-->
<mapper namespace="com.dao.Mapper">
 <!--此處寫對應(yīng)的SQL操作-->
</mapper>

5.功能添加步驟

• 先編寫實體類（pojo）
• dao層：編寫接口，接口對應(yīng)mapper.xml（建議同名）
• service層：編寫接口，編寫接口實現(xiàn)類（創(chuàng)建dao層對象，返回調(diào)用dao層的操作）
• controller層：負(fù)責(zé)具體的業(yè)務(wù)模塊流程的控制，在此層要調(diào)用service層的接口來控制業(yè)務(wù)流程
• 編寫相應(yīng)的jsp文件

6.建議

框架搭建完成后應(yīng)寫個簡單的功能測試框架環(huán)境有無問題
