3、引入bootstrap前端框架

4、编写dispacherServlet-servlet.xml网站跳转逻辑
口决：控制器、视图解析器、两个标配

<!-- 只管网站的跳转逻辑，只扫描控制器，其他不扫描 -->
<context:component-scan base-package="com.atguigu" use-default-filters="false">
<context:include-filtertype="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>

<!-- 两个标准配置 -->
<!-- 不能处理的请求交给tomcat -->
<mvc:default-servlet-handler/>
<!-- 能支持mvc更高级的一些功能，如JSR303校验、快捷的ajax,映射动态请求 -->
<mvc:annotation-driven></mvc:annotation-driven>

5、编写web.xml
口决：contextLoadListener/applicationContext.xml、servlet/dispatherServlet、filter/CharactorEncodingFilter、Rest
风格filter/HiddenHttpMethodFilter

<!-- 1.启动Spring容器 -->
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 2.Spring MVC的前端控制器，拦截所有请求 -->
<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/dispatherServlet-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<!-- Map all requests to the DispatcherServlet for handling -->
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- 3.字符编码过滤器:一定要放在其他过滤器之前 -->
<filter>
<filter-name>CharacterEncodingFilter</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>
<init-param>
<param-name>forceRequestEncoding</param-name>
<param-value>true&l
4000
t;/param-value>
</init-param>
<init-param>
<param-name>forceResponseEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 4.REST风格的URI,将POST请求转化为delete或put请求 -->
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

6、编写applicationContext.xml整合的关键配置文件
口决：exclude控制器、数据源ComboPooledDataSource、
MyBatis整合(sqlSessionFactoryBean+MapperScannerConfigurer)、
事务控制DataSourceTransactionManager(ref/pooledDataSource+aop:config/(pointcut+advisor))、
事务增强 tx:advice

<!-- Spring配置的核心点：数据源、MyBatis整合、事务控制 -->

<!-- ======================配置自动扫描的包：但是除了控制器，和mvc相反========================= -->
<context:component-scan base-package="com.atguigu">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- =======================================================-->

<!-- 数据源 -->
<context:property-placeholder location="classpath:dbconfig.properties"/>
<bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>

<!-- ＝＝＝＝＝＝＝配置和MyBatis的整合＝＝＝＝＝＝＝＝＝＝＝-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定MyBatis全局配置文件的位置 -->
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
<property name="dataSource" ref="pooledDataSource"></property>
<!-- 指定mybatis mapper文件的位置 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
</bean>

<!-- 配置扫描器 ，将MyBatis的接口实现加入到ioc容器中:com.atguigu.crud.dao就是接口的实现-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property  name="basePackage" value="com.atguigu.crud.dao"></property>
</bean>

<!-- 配置一个可以批量执行的sqlSession,如可批量插入 -->
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg>
<constructor-arg name="executorType" value="BATCH"></constructor-arg>
</bean>
<!-- ====================================== -->

<!-- ==================事务控制=================-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 控制住数据源 -->
<property name="dataSource"ref="pooledDataSource"></property>
</bean>
<!-- 开启基于注解的事务，使用xml配置形式的事务（比较主要的都使用配置式） -->
<aop:config>
<!--
切入点表达式:所有类下的所有方法
第一个双点..的意思是即使service包下还有子包也行
双点下的星：所有的类的所有方法
第二个双点：方法里的参数任意多

public 可以不写
-->
<aop:pointcut expression="execution(* com.atguigu.crud.service..*(..) )" id="txPoint"/>

<!-- 配置事务增强 -->
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
</aop:config>

<!-- 配置事务增强，也就是事务如何切入 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!-- 所有方法都是事务方法 -->
<tx:method name="*"/>
<!-- 以get开头的所有方法, read-only是调优 -->
<tx:method name="get*" read-only="true"/>
</tx:attributes>
</tx:advice>

7.mybatis.config.xml

<configuration>
<!--开启驼峰命名法-->
<settings>
<setting name="mapUnderscoreToCamelCase" value="true"/>
</settings>

<!--别名-->
<typeAliases>
<package name="com.atguigu.crud.bean"/>
</typeAliases>

<!--分页合理化-->
<plugins>
<plugin interceptor="com.github.pagehelper.PageInterceptor">
<property name="reasonable" value="true"/>
</plugin>
</plugins>
</configuration>
