8.Eclipse创建一个动态web项目，将其中的web.xml配置文件拷贝到maven项目中，注意修改项目名称。
二、添加xml配置
1.web.xml配置
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="/2001/XMLSchema-instance" xmlns="/xml/ns/javaee" xsi:schemaLocation="/xml/ns/javaee /xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"><display-name>mybatis-spring02</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- web容器启动时根据contextConfigLocation配置的路径读取Spring的配置文件，然后启动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><!-- 配置Springmvc所有的请求都要通过DispatcherServlet --><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc-servlet.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!-- 编码utf-8 --><filter><filter-name>SpringEncodingFilter</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>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>SpringEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping></web-app>
2.springmvc-servlet.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xmlns:context="/schema/context"xmlns:mvc="/schema/mvc"xmlns:tx="/schema/tx"xsi:schemaLocation="/schema/mvc /schema/mvc/spring-mvc-4.3.xsd/schema/beans /schema/beans/spring-beans.xsd/schema/context /schema/context/spring-context-4.3.xsd/schema/tx /schema/tx/spring-tx-4.3.xsd"><!-- 启用Controller注解支持 --><mvc:annotation-driven></mvc:annotation-driven><!-- 配置一个简单的静态资源映射规则 --><mvc:resources location="static/" mapping="/static/**"></mvc:resources><!-- 扫描Controller包下面的类 --> <context:component-scan base-package="com.watermelon.*.controller"></context:component-scan><!-- InternalResourceViewResolver将视图名映射为URL文件 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property><property name="prefix" value="/WEB-INF/jsp/"></property><property name="suffix" value=".jsp"></property></bean></beans>
3.mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configurationPUBLIC "-////DTD Config 3.0//EN""/dtd/mybatis-3-config.dtd"><configuration><settings><setting name="logImpl" value="LOG4J"/><setting name="cacheEnabled" value="true"/><setting name="mapUnderscoreToCamelCase" value="true"/><setting name="aggressiveLazyLoading" value="false"/></settings></configuration>
4.log4j.properties
