①在建立好的maven项目中的pom.xml文件引入依赖，代码如下：

<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/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>wechat.cuiyongzhi.com</groupId>  <artifactId>wechat</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>wechat</name>  <url>http://maven.apache.org</url>  <dependencies>   <!-- spring -->   <dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-test</artifactId>    <version>3.2.0.RELEASE</version>   </dependency>   <dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-webmvc</artifactId>    <version>3.2.0.RELEASE</version>   </dependency>   <dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-core</artifactId>    <version>3.2.0.RELEASE</version>   </dependency>     <!-- mybatis -->   <dependency>    <groupId>org.mybatis</groupId>    <artifactId>mybatis</artifactId>    <version>3.1.1</version>   </dependency>   <dependency>    <groupId>org.mybatis</groupId>    <artifactId>mybatis-spring</artifactId>    <version>1.1.1</version>   </dependency>     <!-- mysql -->   <dependency>    <groupId>mysql</groupId>    <artifactId>mysql-connector-java</artifactId>    <version>5.1.21</version>   </dependency>     <!-- junit测试 -->   <dependency>    <groupId>junit</groupId>    <artifactId>junit</artifactId>    <version>4.11</version>    <scope>test</scope>   </dependency>     <!-- mysql阿里连接池druid -->   <dependency>    <groupId>com.alibaba</groupId>    <artifactId>druid</artifactId>    <version>0.2.9</version>   </dependency>     <!-- spring aop包 -->   <dependency>    <groupId>org.aspectj</groupId>    <artifactId>aspectjweaver</artifactId>    <version>1.7.1</version>   </dependency>     <!-- json包 -->   <dependency>    <groupId>com.alibaba</groupId>    <artifactId>fastjson</artifactId>    <version>1.2.7</version>   </dependency>     <!-- 文件上传包 -->   <dependency>    <groupId>commons-fileupload</groupId>    <artifactId>commons-fileupload</artifactId>    <version>1.2.2</version>   </dependency>     <!--servlet包 -->   <dependency>    <groupId>javax.servlet</groupId>    <artifactId>servlet-api</artifactId>    <version>3.0-alpha-1</version>   </dependency>     <dependency>    <groupId>javax.servlet.jsp</groupId>    <artifactId>jsp-api</artifactId>    <version>2.1</version>    <scope>provided</scope>   </dependency>     <dependency>    <groupId>javax.servlet</groupId>    <artifactId>jstl</artifactId>    <version>1.2</version>   </dependency>     <!-- 日志包 -->   <dependency>    <groupId>log4j</groupId>    <artifactId>log4j</artifactId>    <version>1.2.17</version>   </dependency>  </dependencies>  <build>   <finalName>wechat</finalName>  </build> </project>

②修改项目路径下的web.xml文件如下：

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

   <include-prelude>/WEB-INF/common/head.jsp</include-prelude>   </jsp-property-group>  </jsp-config>   </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=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">  <!-- 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  http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context-4.0.xsd  http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    <!-- 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>     <value>text/html;charset=UTF-8</value>    </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>   </property>  </bean>    </beans>

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

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：

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：
