maven构建spring mvc项目 + Mybatis整合

一、新建项目

1、File>New>Other>Maven>Maven Project, 点击Next

 


2、选择项目保存路径。然后点击Next。
 


3、选择项目类型，在Artifact Id中选择maven-archetype-webapp，然后点击Next。
 


4、Group ID一般写大项目名称。Artifact ID是子项目名称。
例如Spring的web包，Group ID：org.springframework，artifactId：spring-web。
Package是默认给你建一个包，不写也可以。
填完后，点击Finish。

5、建好后的项目结构如下：

 
6、打开cmd命令窗口，cd到项目的跟目录。执行以下语句：
mvn clean eclipse:eclipse

注：
mvn clean     //清理（删除target目录下编译内容）

mvn eclipse:eclipse   //生成Eclipse项目结构

7、选中项目，右击：New>Other>java>Source Folder，点击Next
 


8、以下Floder Name必须为src/main/java
 


9、现目录结构如下：
 




二、配置文件设置（附部分配置说明）
1、pom.xml

<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>cn.com.abel</groupId><artifactId>springProject</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>springProject Maven Webapp</name><url>http://maven.apache.org</url>      <properties><slf4j.version>1.6.4</slf4j.version><spring.version>3.1.2.RELEASE</spring.version><jdk.version>1.6</jdk.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies>    <dependency>    <groupId>junit</groupId>    <artifactId>junit</artifactId>    <version>3.8.1</version>    <scope>test</scope>    </dependency>        <!-- spring begin -->    <dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version><type>jar</type><scope>compile</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-core</artifactId>   <version>${spring.version}</version>   </dependency>   <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-beans</artifactId>   <version>${spring.version}</version>   </dependency>   <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-context</artifactId>   <version>${spring.version}</version>   </dependency>   <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-aop</artifactId>   <version>${spring.version}</version>   </dependency>   <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-tx</artifactId>   <version>${spring.version}</version>   </dependency>      <dependency>   <groupId>org.aspectj</groupId>   <artifactId>aspectjrt</artifactId>   <version>1.6.9</version>   </dependency>   <dependency>   <groupId>org.aspectj</groupId>   <artifactId>aspectjweaver</artifactId>   <version>1.6.9</version>   </dependency>   <dependency>   <groupId>cglib</groupId>   <artifactId>cglib-nodep</artifactId>   <version>2.2</version>   </dependency>   <!-- spring end -->      <!-- mybatis begin --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.1.1</version><type>jar</type><scope>compile</scope></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.1.1</version><type>jar</type><scope>compile</scope></dependency><!-- mybatis end --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.21</version><type>jar</type><scope>compile</scope></dependency><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.19</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version><scope>provided</scope></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.16</version></dependency></dependencies><build><finalName>springProject</finalName><plugins><!-- jetty插件 --><plugin><groupId>org.mortbay.jetty</groupId><artifactId>maven-jetty-plugin</artifactId><version>6.1.25</version></plugin><plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.1</version><configuration><configurationFile>src/main/resources/mybatis-generator.xml</configurationFile><overwrite>true</overwrite></configuration></plugin></plugins></build>  </project>

2、web.xl

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"version="2.5">   <display-name>springProject Application</display-name>      <!-- 指定上下文配置文件 -->   <context-param><param-name>contextConfigLocation</param-name><param-value> classpath:applicationContext.xml</param-value></context-param><!-- spring监听器，监听springMvc环境 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 压入项目路径 --><listener>   <listener-class>org.springframework.web.util.WebAppRootListener</listener-class></listener>   <!-- springMvc前置总控制器，在分发其它的控制器前都要经过这个总控制器 --> <servlet><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/spring-servlet.xml</param-value></init-param><!-- 启动顺序 --><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>/</url-pattern><!-- <url-pattern>/</url-pattern>  会匹配到/login这样的路径型url，不会匹配到模式为*.jsp这样的后缀型url<url-pattern>/*</url-pattern> 会匹配所有url：路径型的和后缀型的url(包括/login,*.jsp,*.js和*.html等) --></servlet-mapping></web-app>

3、spring-servlet.xml

6、IndexController.java

package cn.com.abel.springProject.controller;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import cn.com.abel.springProject.dao.TestModelMapper;import cn.com.abel.springProject.model.TestModel;/**TestModelMapper与TestModel为Mybatis自动生成的dao和model*/@Controller@RequestMapping("")public class IndexController {@Autowiredprivate TestModelMapper testDao;@RequestMappingpublic String index(ModelMap model) {//从testTable中查找ID为1的记录TestModel testModel = testDao.selectByPrimaryKey(1L);model.addAttribute("testModel", testModel);model.addAttribute("hello", "hfffello spring mvc");return "index";}}
