基本结构就是这样的。
在这里插入图片描述在整合之前，要引入相关包，我的版本肯会旧一点

1.web.xml文件(主要内容)
1. 启动Spring的容器
2.配置SpringMvc的前端控制器 拦截所有请求
具体配置

        <filter-name>HiddenHttpMethodFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

2.SpringMvc配置
包含 网站跳转逻辑的 控制 及 配置
具体配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:task="http://www.springframework.org/schema/task"
	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 
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task.xsd">

	<!-- SpringMvc的配置文件 包含 网站跳转逻辑的控制及配置 -->

	<!-- 1.自动扫描 use-default-filters-只扫描默认的 -->
	<context:component-scan base-package="com.smxy.maven.crud"
		use-default-filters="false">
		<!-- 只扫描控制器 -->
		<context:include-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
		<!--<context:include-filter type="annotation"
			expression="org.springframework.web.bind.annotation.ControllerAdvice" />-->
	</context:component-scan>
	<!-- 2.配置视图解析器，方便页面返回 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/views/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	<!-- 3.俩个标准配置 -->
	<!-- 将mvc不能处理的请求交给tomcat,实现静态资源也可以访问成功 -->
	<mvc:default-servlet-handler />
	<!-- 能支持SpringMvc更高级的一些功能,映射动态请求，JSR303校验，快捷的ajax -->
	<mvc:annotation-driven />
</beans>

3.Spring配置
主要配置和业务逻辑有关的，例如：MyBatis整合配置，数据源，事务控制
具体代码

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

	<!-- Spring的配置文件 主要配置和业务逻辑有关的 （整合配置）,数据源，事务控制 -->

	<!-- 除了控制业务不扫描，其他都扫描 -->
	<context:component-scan base-package="com.smxy.maven.crud">
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>

	<!-- ===============================数据源的配置================================================ -->
	<!-- 用context引入外部文件dbconfig.properties -->
	<context:property-placeholder location="classpath:dbconfig.properties" />
	<!-- 配置数据源C3P0 -->
	<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>


	<!-- ===============================MyBatis整合配置================================================ -->
	<!-- 配置和MyBatis的整合 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 指定mybatis,mapper文件的位置 -->
		<!-- 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>
		<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
	</bean>
	<!-- 配置扫描器，将myBatis接口的实现加入到ioc容器中 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!-- 扫描所有dao接口的实现，加入到ioc容器 -->
		<property name="basePackage" value="com.smxy.maven.crud.dao"></property>
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
	</bean>
	<!-- ============================================================================================ -->
	<!-- 配置一个可以批量执行的SqlSession -->
	<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>
	
	<!-- ============================================================================================ -->

	<!-- ===============================事务控制的配置================================================ -->

	<!-- 事务控制 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<!-- 控制数据源 开启、关闭、回控 -->
		<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（主要时用配置事务） aop -->
	<aop:config>
		<!-- 切入点表达式 -->
		<aop:pointcut id="txPoint"
			expression="execution(* com.smxy.maven.crud.service..*(..))" />
		<!-- 配置事务增强 tx -->
		<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint" />
		<!-- 切入面 -->

	</aop:config>

	<!-- 事务增强 事务如何切入 -->
	<tx:advice id="txAdvice" ><!--transaction-manager="transactionManager">-->
		<tx:attributes>
			<!-- *代表所有方法都是事务方法 -->
			<tx:method name="*" />
			<!-- 以get开头的所有方法(只是查询) -->
			<tx:method name="get*" read-only="true" />
		</tx:attributes>
	</tx:advice>
	<!-- ============================================================================================= -->
</beans>

4.数据源配置，引用的是dbconfig.properties文件，这个文件的主要内容是

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_cure
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=123456

5.整合MyBatis时，要指定mybatis,mapper文件的位置，还要扫描所有dao接口的实现。[在Spring配置文件中有]。
这里展示一下MyBatis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">

<!-- MyBatis配置文件 -->
<configuration>
	<settings>
		<setting name="mapUnderscoreToCamelCase" value="true" />
	</settings>
	<!-- 类型别名，就是实体类的存放路径 -->
	<typeAliases>
		<package name="com.smxy.maven.crud.pojo" />
	</typeAliases>

	<!-- 在 MyBatis 配置 分页拦截器插件 -->
	<plugins>
		<!-- com.github.pagehelper为PageHelper类所在包名 -->
		<plugin interceptor="com.github.pagehelper.PageInterceptor">
			<!-- 使用下面的方式配置参数，后面会有所有的参数介绍 -->
			<!-- 分页合理化 -->
			<property name="reasonable" value="true" />
		</plugin>
	</plugins>

</configuration>
