项目构建步骤
1、File->New->Project
勾选Create from archetype
点击Next
2、输入GroupId、ArtifactId
点击Next
3、继续点击Next，输入Project name
点击Finish，完成基本项目创建
4、在src/main下添加java目录作为源文件目录
在main上右键new Directory并命名为java；
同时在Project Structure中，将java目录设置为Sources，然后Apply，点击OK。
5、配置pom.xml
可以在maven仓库进行相关依赖搜索：http://www.mvnrepository.com/
利用<dependency>元素进行项目所依赖的jar包配置，maven通过对pom.xml的配置使得不再需要导入jar包那么麻烦
6、配置tomcat
MavenDemo简单实例
1、项目结构
注： 在WEB-INFO/lib下存放有jstl.jar和standard.jar，需要将其导入项目的Libraries中
如图：
2、pom.xml配置
<?xml version="1.0" encoding="UTF-8"?> <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> <packaging>war</packaging> <name>MavenDemo</name> <groupId>MavenDemo</groupId> <artifactId>MavenDemo</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <!-- spring start--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.1.6.RELEASE</version> </dependency> <!-- spring end--> <!-- mybatis start--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- mybatis end--> <!-- mysql connector start--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.34</version> </dependency> <!-- mysql connector end--> <!-- junit start--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> </dependency> <!-- junit end--> <!-- 阿里巴巴数据源包 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.2</version> </dependency> </dependencies> </project>
3、web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
4、applicationContext.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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd "> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/mybatis" /> <property name="username" value="root" /> <property name="password" value="root" /> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="mapper" /> </bean> </beans>
5、dispathcer-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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <mvc:default-servlet-handler /> <mvc:annotation-driven /> <context:component-scan base-package="controller" /> <context:component-scan base-package="mapper" /> <context:component-scan base-package="service" /> <bean id="viewResovler" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>

package service.impl; import mapper.UserMapper; import model.User; import org.springframework.stereotype.Service; import service.UserService; import javax.annotation.Resource; import java.util.List; /** * Created by Roger on 2015/9/17. */ @Service("userService") public class UserServiceImpl implements UserService { @Resource(name = "userMapper") private UserMapper userMapper; public List<User> selectAll() { return userMapper.selectAll(); } } 9、controller/UserController.java
package controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import service.UserService; import javax.annotation.Resource; /** * Created by Roger on 2015/9/17. */ @Controller public class UserController { @Resource(name = "userService") private UserService userService; @RequestMapping("/getUser") public String getUser(Model model) { System.out.println(userService.selectAll().size()); model.addAttribute("user", userService.selectAll()); return "listUser"; } } 10、WEB-INFO/jsp/listUser.jsp
<%-- Created by IntelliJ IDEA. User: Roger Date: 2015/9/17 Time: 11:01 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %> <html> <head> <title>list user</title> </head> <body> <c:forEach items="${user}" var="item"> ${item.id}--${item.name} <br> </c:forEach> </body> </html> 11、运行结果
通过getUser来访问数据库中user表格的数据
