前面一篇有说道如何在MyEclipse中搭建maven项目，这里将继续介绍如何在搭建好的基础maven项目中引入我们常用的javaweb框架——SpringMVC！

①在建立好的maven项目中的pom.xml文件引入依赖，代码如下：

</web-app>

③添加数据库配置信息，这里项目配置的数据库为mysql，在 resources下新建config.properties配置文件，设置如下：

validationQuery=SELECT 1
jdbc_url=jdbc:mysql://127.0.0.1:3306/wechat?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc_username=root  
jdbc_password=123456789

④在 resources下新建spring.xml配置文件，设置如下：

<?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" xsi:schemaLocation="

    <!-- 引入属性文件 -->

    <context:property-placeholder location="classpath:config.properties" />

    <!-- 自动扫描(自动注入) -->

    <context:component-scan base-package="com.cuiyongzhi.web.service" />

    <context:component-scan base-package="com.cuiyongzhi.wechat.*" /> 

</beans>

⑤在 resources下新建spring-mvc.xml配置文件，设置如下：

<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans

    <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->

    <context:component-scan base-package="com.cuiyongzhi.web.controller" />
 
    <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->

    <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

        <property name="supportedMediaTypes">

            <list>

        </property>

    </bean>
 
    <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->

    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

        <property name="messageConverters">

            <list>

                <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->

            </list>

        </property>

    </bean>
 
    <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/views/" p:suffix=".jsp" />
 
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <property name="defaultEncoding">

            <value>UTF-8</value>

        </property>

        <property name="maxUploadSize">

            <value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 -->

        </property>

        <property name="maxInMemorySize">

            <value>4096</value>

    </bean>

</beans>

⑥在 resources下新建spring-mybatis.xml配置文件，设置如下：

    <aop:config>

        <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" />

    </aop:config>
 
</beans>

⑦在 resources下新建log4j.properties配置文件，用于日志的输出等级以及输出位置设置，设置如下：

log4j.rootLogger=DEBUG,Console,File
 
#ERROR,WARN,INFO,DEBUG
 
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Threshold=DEBUG
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n
 
log4j.appender.File=org.apache.log4j.DailyRollingFileAppender 
log4j.appender.File.File=${catalina.base}/wechatlogs/wechat.log
log4j.appender.File.Threshold=INFO
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.Append=true
log4j.appender.File.ImmediateFlush=true
log4j.appender.File.DatePattern=yyyy-MM-dd‘.log‘
log4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

到这里springmvc+mybatis的基本配置文件基本就完成了，大致的项目结构如下：
