本文详细介绍了如何搭建SSM（Spring + SpringMVC + MyBatis）框架，并提供了从项目初始化到各模块配置的完整步骤。

废话就不多说了啊，接下里我们就来搭建SSM架构吧！

一：项目搭建成型的工程：

二：先创建一个mvven工程。

注意：由于这个工程我自己创建过，所以会报错，大家第一创建就没问题啊。

二：pom.xml中进行jar包的依赖。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

三：spring整合springmvc的配置文件：

applicationContext.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:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    <!--扫描controller的包  -->
	<context:component-scan base-package="com.yiyi.crud">
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>

	<!-- Spring的配置文件，这里主要配置和业务逻辑有关的 -->
	<!--=================== 数据源，事务控制，xxx ================-->
	<context:property-placeholder location="classpath:dbconfig.properties" />
	<bean id="dataSourse" class="com.mchange.v2.c3p0.CombodataSourse">
		<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="dataSourse"></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容器中 -->
		<property name="basePackage" value="com.yiyi.crud.dao"></property>
	</bean>
	
	<!-- 配置一个可以执行批量的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 ================-->
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<!--控制住数据源  -->
		<property name="dataSource" ref="dataSourse"></property>
	</bean>
	<!--开启基于注解的事务，使用xml配置形式的事务（必要主要的都是使用配置式）  -->
	<aop:config>
		<!-- 切入点表达式 -->
		<aop:pointcut expression="execution(* com.yiyi.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，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开始的所有方法  -->
			<tx:method name="get*" read-only="true"/>
		</tx:attributes>
	</tx:advice>
	
	<!-- Spring配置文件的核心点（数据源、与mybatis的整合，事务控制） -->
	
</beans>

四：数据源：

dbconfig.properties

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

五：spring整合Springmvc的配置文件：

dispatcherServlet-servlet.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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

	<!--SpringMVC的配置文件  -->
	<context:component-scan base-package="com.yiyi" use-default-filters="false">
		<!--只扫描控制器。  -->
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
	
	<!--配置视图解析器 -->
	<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  -->
	<!-- 将springmvc不能处理的请求交给tomcat -->
	<mvc:default-servlet-handler/>
	<!-- 能支持springmvc更高级的一些功能，JSR303校验，快捷的ajax...映射动态请求 -->
	<mvc:annotation-driven/>

</beans>

六：spring整合mybatis的配置文件：

其中有的配置文件在applicationContext.xml中已经进行配置;

mybatis-config.xml:

<?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>
	<settings>
		<setting name="mapUnderscoreToCamelCase" value="true"/>
	</settings>
	
	<typeAliases>
		<package name="com.yiyi.crud.bean"/>
	</typeAliases>
	
	<plugins>
		<plugin interceptor="com.github.pagehelper.PageInterceptor">
			<!--分页参数合理化  -->
			<property name="reasonable" value="true"/>
		</plugin>
	</plugins>

</configuration>

七：web.xml的配置文件：

web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>

	<!--1、启动Spring的容器  -->
	<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、springmvc的前端控制器，拦截所有请求  -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<!-- 3、字符编码过滤器，一定要放在所有过滤器之前 -->
	<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</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、使用Rest风格的URI，将页面普通的post请求转为指定的delete或者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>
	<filter>
		<filter-name>HttpPutFormContentFilter</filter-name>
		<filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>HttpPutFormContentFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
</web-app>

所以的配置文件都已经全部完成。

那么接下来的完成下一步吧。
