这篇文章主要为大家详细介绍了开发准备第二步，springmvc和mybatis项目结构的搭建，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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：
<project> <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>
