一、创建Maven-Web工程

				</configuration>
			</plugin>
		</plugins>
	</build>

三、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="WebApp_ID"
	version="3.0">

	<!-- 启动Spring -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- Spring MVC -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:dispatcherServlet-servlet.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>

	<!-- 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>
		<!-- 指定字符编码集 -->
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf-8</param-value>
		</init-param>
		<!-- request 编码 -->
		<init-param>
			<param-name>forceRequestEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
		<!-- response 编码 -->
		<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 -->
	<!-- 增加 _method 参数 -->
	<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>

四、Spring配置文件applicationContext.xml

首先需要dbconfig.properties来配置数据库联系信息

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

dbconfig.properties的信息在下方applicationContext.xml以${jdbc.jdbcUrl}方式引用

<?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">

	<!-- 包扫描器 com.cspticw包需要结合具体项目-->
	<context:component-scan base-package="com.cspticw">
		<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="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 需要结合具体项目结构-->
		<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 com.cspticw.dao包需要结合具体项目-->
		<property
			name="basePackage"
			value="com.cspticw.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="pooledDataSource"></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） com.cspticw.service包需要结合具体项目-->
	<aop:config>
		<!-- 切入点表达式 -->
		<aop:pointcut
			expression="execution(* com.cspticw.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:method
				name="find*"
				read-only="true" />
			<tx:method
				name="select*"
				read-only="true" />
		</tx:attributes>
	</tx:advice>
</beans>

注意：applicationContext.xml 中的包需要结合具体项目。

五、SpringMVC配置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，包含网站跳转逻辑的控制，配置 com.cspticw需要结合具体项目结构 -->
	<context:component-scan base-package="com.cspticw" 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，方便页面返回  -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/pages/"></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、MyBatis配置mybatis-config.xml（可以不需要）

<?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>

	<!-- 驼峰命名开启 -->
	<settings>
		<setting
			name="mapUnderscoreToCamelCase"
			value="true" />
	</settings>
	<plugins>
		<plugin interceptor="com.github.pagehelper.PageInterceptor">
			<!--分页参数合理化 -->
			<property
				name="reasonable"
				value="true" />
		</plugin>
	</plugins>
</configuration>  

注意：MyBatis逆向工程参见：MyBatis逆向工程——MyBatis Generator (MBG)-简单介绍与运行步骤（1）

七、日志log4j.properties

log4j.rootLogger=debug, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n

注意：只需要把此文件放到classpath目录下。
