一、两个容器整合✨

1、先准备好数据库config.properties连接、mybatis-config.xml🎊

（1）数据库config.properties连接

driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/emp?serverTimeZone=Asia/ShangHai&useUnicode=true&characterEncoding=utf8&useSSL=false
username=root
password=nigx=0128

（2）mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><!-- <properties resource="config.properties"> --><!-- </properties> --><settings><!--将表中字段的下划线自动转换为驼峰--><setting name="mapUnderscoreToCamelCase" value="true"/><setting name="logImpl" value="STDOUT_LOGGING"/><!-- 如果需要更改一级缓存的范围，可以在Mybatis的配置文件中，在下通过localCacheScope指定。 --><!-- <setting name="localCacheScope" value="STATEMENT"/> --></settings><!--  类型别名配置各个标签时，需要遵守前后顺序--><typeAliases><package name="com.pojo"/></typeAliases><!--    <typeAliases>--><!--        <typeAlias alias="user" type="com.pojo.User"></typeAlias>--><!--        <typeAlias type="com.pojo.Employee"></typeAlias>--><!--        <typeAlias type="com.pojo.Log"></typeAlias>--><!--        <typeAlias type="com.pojo.Dept"></typeAlias>--><!--    </typeAliases>--><!--  environments：配置数据库的连接环境信息，可以配置多个environment，通过default属性切换不同的environment  --><!-- <environments default="development"> --><!--     <environment id="development"> --><!--         <transactionManager type="JDBC"/> --><!--         &lt;!&ndash;数据库连接池&ndash;&gt; --><!--         <dataSource type="POOLED"> --><!--             &lt;!&ndash;数据库的连接信息&ndash;&gt; --><!--             <property name="driver" value="${driver}"/> --><!--             <property name="url" value="${url}"/> --><!--             <property name="username" value="${username}"/> --><!--             <property name="password" value="${password}"/> --><!--         </dataSource> --><!--     </environment> --><!-- </environments> --><mappers><!--加载SQL映射文件--><!--<mapper resource="nigaoxian\mapper\UserMapper.xml"/>--><!--  Mapper 代理方式，在spring容器映射过就不需要配置了--><!-- <package name="com.dao"/> --></mappers>
</configuration>

2、容器一：优先配置spring.xml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" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttps://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><!-- 2*3+1 --><!--扫描组件（除控制层）--><context:component-scan base-package="com.service,com.service.serviceImpl,com.interceptor,com.exception"><!-- 按照注解进行排除，标注了指定注解的组件不要扫描 --><!--        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>--><!-- 指定排除某个具体的类，按照类排除  --><!-- <context:exclude-filter type="assignable" expression="com.controller.EmpController"/> --></context:component-scan><!-- 配置数据源 --><!--引入config.properties--><bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:config.properties</value></list></property></bean><!-- 配置数据参数与连接属性 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"><property name="driverClass" value="${driver}"></property><property name="maxPoolSize" value="100"></property><property name="minPoolSize" value="30"></property><property name="jdbcUrl" value="${url}"></property><property name="user" value="${username}"></property><property name="password" value="${password}"></property></bean><!-- 配置spring事务管理器 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean><!--开启事务的注解驱动，将使用注解 @Transactional 标识的方法或类中所有的方法进行事务关联--><tx:annotation-driven transaction-manager="transactionManager"/><!-- 配置SqlSessionFactoryBean，可以直接在Spring的IOC中获取SqlSessionFactory--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- 设置MyBatis的核心配置文件的路径 --><property name="configLocation" value="classpath:mybatis-config.xml"/><!-- 设置数据源 --><property name="dataSource" ref="dataSource"/><!-- 设置类型别名，默认为类名 --><!-- <property name="typeAliasesPackage" value="com.pojo"/> --><!-- 设置映射文件所在的包，只有在映射文件的包和mapper接口的包不一致时需要设置 --><property name="mapperLocations" value="classpath:com/dao/*.xml"/><!--引入分页插件--><!-- <property name="plugins"> --><!--     <array> --><!--         <bean class="com.github.pagehelper.PageInterceptor"/> --><!--     </array> --><!-- </property> --></bean><!--配置mapper接口的扫描配置，由mybatis-spring提供，可以将指定包下所有的mapper接口创建动态代理，并将这些动态代理作为IOC容器的bean管理，可以直接在Spring的IOC中获取Mapper接口了。--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/><property name="basePackage" value="com.dao"/></bean>
</beans>

3、容器二：配置springMVC.xml文件🎊

<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"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- 启动mvc注解驱动 --><mvc:annotation-driven/><!-- 配置扫描的包 --><context:component-scan base-package="com.controller"/><!-- 配置视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/"></property><property name="suffix" value=".jsp"></property></bean><mvc:cors><mvc:mapping path="/**" allowed-origins="*" allowed-headers="*" allowed-methods="*" allow-credentials="false"max-age="3600"/></mvc:cors><mvc:interceptors><mvc:interceptor><mvc:mapping path="/**"/><bean id="corsInterceptor" class="com.interceptor.CORSInterceptor"/></mvc:interceptor><mvc:interceptor><mvc:mapping path="/**"/><mvc:exclude-mapping path="/login"/><mvc:exclude-mapping path="/register"/><bean id="loginInterceptor" class="com.interceptor.LoginInterceptor"/></mvc:interceptor></mvc:interceptors>
</beans>

4、Tomcat整合spring容器、springMVC容器，webapp文件下的web.xml文件🎊

<!DOCTYPE web-app PUBLIC"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN""http://java.sun.com/dtd/web-app_2_3.dtd" ><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"><!-- tomcat整合spring --><!--配置Spring的编码过滤器--><!--配置Spring的监听器，在服务器启动的时候加载Spring的配置文件 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!--设置spring配置文件自定义的位置和名称--><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></context-param><!-- <filter> --><!--     <filter-name>CharacterEncodingFilter</filter-name> --><!--     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> --><!--     &lt;!&ndash;只设置这个只会处理请求的编码，两个都设置请求响应都会处理&ndash;&gt; --><!--     <init-param> --><!--         <param-name>encoding</param-name> --><!--         <param-value>UTF-8</param-value> --><!--     </init-param> --><!--     <init-param> --><!--         <param-name>forceEncoding</param-name> --><!--         <param-value>true</param-value> --><!--     </init-param> --><!-- </filter> --><!-- <filter-mapping> --><!--     <filter-name>CharacterEncodingFilter</filter-name> --><!--     <url-pattern>/*</url-pattern> --><!-- </filter-mapping> --><!-- &lt;!&ndash; 配置处理请求方式PUT和DELETE的过滤器&ndash;&gt; --><!-- <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> --><!-- tomcat整合spring --><!-- 配置SpringMVC的前端控制器 --><servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 设置SpringMVC的配置文件的位置和名称 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springMVC.xml</param-value></init-param><!-- 将DispatcherServlet的初始化时间提前到服务器启动时--><load-on-startup>1</load-on-startup></servlet><!-- 为什么使用/，并且这里为什么会默认放行jsp？设置/是为了兜底的，因为只有一个servlet，就是默认为DispatcherServlet的servlet，需要使用这个servlet拦截请求。因为jsp底层本身就是servlet，设置多个servlet此时只映射的是DispatcherServlet--><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>

二、一个容器整合

1、 现在去掉了spring.xml文件，将spring.xml文件的内容放到springMVC🎊

springMVC.xml文件如下：

<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"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- 2*3+1 --><!--扫描组件（除控制层）--><context:component-scan base-package="com.service,com.service.serviceImpl,com.interceptor,com.exception"><!-- 按照注解进行排除，标注了指定注解的组件不要扫描 --><!--        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>--><!-- 指定排除某个具体的类，按照类排除  --><!-- <context:exclude-filter type="assignable" expression="com.controller.EmpController"/> --></context:component-scan><!-- 配置数据源 --><!--引入config.properties--><bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:config.properties</value></list></property></bean><!-- 配置数据参数与连接属性 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"><property name="driverClass" value="${driver}"></property><property name="maxPoolSize" value="100"></property><property name="minPoolSize" value="30"></property><property name="jdbcUrl" value="${url}"></property><property name="user" value="${username}"></property><property name="password" value="${password}"></property></bean><!-- 配置spring事务管理器 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean><!--开启事务的注解驱动，将使用注解 @Transactional 标识的方法或类中所有的方法进行事务关联--><tx:annotation-driven transaction-manager="transactionManager"/><!-- 配置SqlSessionFactoryBean，可以直接在Spring的IOC中获取SqlSessionFactory--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- 设置MyBatis的核心配置文件的路径 --><property name="configLocation" value="classpath:mybatis-config.xml"/><!-- 设置数据源 --><property name="dataSource" ref="dataSource"/><!-- 设置类型别名，默认为类名 --><!-- <property name="typeAliasesPackage" value="com.pojo"/> --><!-- 设置映射文件所在的包，只有在映射文件的包和mapper接口的包不一致时需要设置 --><property name="mapperLocations" value="classpath:com/dao/*.xml"/><!--引入分页插件--><!-- <property name="plugins"> --><!--     <array> --><!--         <bean class="com.github.pagehelper.PageInterceptor"/> --><!--     </array> --><!-- </property> --></bean><!--配置mapper接口的扫描配置，由mybatis-spring提供，可以将指定包下所有的mapper接口创建动态代理，并将这些动态代理作为IOC容器的bean管理，可以直接在Spring的IOC中获取Mapper接口了。--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/><property name="basePackage" value="com.dao"/></bean><!-- 启动mvc注解驱动 --><mvc:annotation-driven/><!-- 配置扫描的包 --><context:component-scan base-package="com.controller"/><!-- 配置视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/"></property><property name="suffix" value=".jsp"></property></bean><mvc:cors><mvc:mapping path="/**" allowed-origins="*" allowed-headers="*" allowed-methods="*" allow-credentials="false"max-age="3600"/></mvc:cors><mvc:interceptors><mvc:interceptor><mvc:mapping path="/**"/><bean id="corsInterceptor" class="com.interceptor.CORSInterceptor"/></mvc:interceptor><mvc:interceptor><mvc:mapping path="/**"/><mvc:exclude-mapping path="/login"/><mvc:exclude-mapping path="/register"/><bean id="loginInterceptor" class="com.interceptor.LoginInterceptor"/></mvc:interceptor></mvc:interceptors>
</beans>

2、Tomcat整合springMVC容器，webapp文件下的web.xml文件🎊

<!DOCTYPE web-app PUBLIC"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN""http://java.sun.com/dtd/web-app_2_3.dtd" ><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"><!-- tomcat整合springMVC --><!-- 配置SpringMVC的前端控制器 --><servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 设置SpringMVC的配置文件的位置和名称 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springMVC.xml</param-value></init-param><!-- 将DispatcherServlet的初始化时间提前到服务器启动时--><load-on-startup>1</load-on-startup></servlet><!-- 为什么使用/，并且这里为什么会默认放行jsp？设置/是为了兜底的，因为只有一个servlet，就是默认为DispatcherServlet的servlet，需要使用这个servlet拦截请求。因为jsp底层本身就是servlet，设置多个servlet此时只映射的是DispatcherServlet--><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>
