這篇文章主要講解使用eclipse對Spirng+SpringMVC+Maven+Mybatis+MySQL項目搭建過程，包括里面步驟和里面的配置文件如何配置等等都會詳細說明。 如果還沒有搭建好環境（主要是Maven+MySQL的配置）的猿友可以參考博主以前的一篇文章： [http://blog.csdn.net/u013142781/article/details/50300233](http://blog.csdn.net/u013142781/article/details/50300233) 接下來馬上進入項目搭建過程： ### 1、創建表，并插入數據： ~~~ CREATE TABLE `t_user` ( `USER_ID` int(11) NOT NULL AUTO_INCREMENT, `USER_NAME` char(30) NOT NULL, `USER_PASSWORD` char(10) NOT NULL, PRIMARY KEY (`USER_ID`), KEY `IDX_NAME` (`USER_NAME`) ) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8 ~~~ ~~~ INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, 'luoguohui', '123456'); INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, 'zhangsan', '123456'); ~~~ ### 2、Maven工程創建  ### 3、選擇快速框架  ### 4、輸出項目名，包（Packaging，如果只是普通的項目，選jar就好了，如果是web項目就選war，這里是web項目，所以選擇war）  ### 5、創建好的目錄如下：  ### 6、添加包的依賴，編輯pom.xml文件添加如下依賴： ~~~ <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/xsd/maven-4.0.0.xsd">

<!-- mysql驅動包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> </dependencies> </project> ~~~ ### 7、配置文件：  7.1、mybatis包下添加mybatis-config.xml文件（mybatis配置文件）： ~~~ <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> </configuration> ~~~ 7.2、properties包下添加jdbc.properties文件（數據源配置文件）： ~~~ jdbc_driverClassName=com.mysql.jdbc.Driver jdbc_url=jdbc:mysql://localhost:3306/luo jdbc_username=root jdbc_password=root ~~~ 7.3、mapper包下userMapper.xml配置文件（表映射文件）： ~~~ <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.luo.dao.UserDao"> <!--設置domain類和數據庫中表的字段一一對應，注意數據庫字段和domain類中的字段名稱不致，此處一定要！--> <resultMap id="BaseResultMap" type="com.luo.domain.User"> <id column="USER_ID" property="userId" jdbcType="INTEGER" /> <result column="USER_NAME" property="userName" jdbcType="CHAR" /> <result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" /> </resultMap> <!-- 查詢單條記錄 --> <select id="selectUserById" parameterType="int" resultMap="BaseResultMap"> SELECT * FROM t_user WHERE USER_ID = #{userId} </select> </mapper> ~~~ 7.4、spring配置文件application.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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 引入jdbc配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:properties/*.properties</value> <!--要是有多個配置文件，只需在這里繼續添加即可 --> </list> </property> </bean> <!-- 配置數據源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <!-- 不使用properties來配置 --> <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/learning" /> <property name="username" value="root" /> <property

<value>${jdbc_url}</value> </property> <property name="username"> <value>${jdbc_username}</value> </property> <property name="password"> <value>${jdbc_password}</value> </property> </bean> <!-- 自動掃描了所有的XxxxMapper.xml對應的mapper接口文件，這樣就不用一個一個手動配置Mpper的映射了，只要Mapper接口類和Mapper映射文件對應起來就可以了。 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.luo.dao" /> </bean> <!-- 配置Mybatis的文件 ，mapperLocations配置**Mapper.xml文件位置，configLocation配置mybatis-config文件位置--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="typeAliasesPackage" value="com.tiantian.ckeditor.model" /> --> </bean> <!-- 自動掃描注解的bean --> <context:component-scan base-package="com.luo.service" /> </beans> ~~~ ### 8、接口和類的配置：  8.1、com.luo.domain下添加User.java文件： ~~~ package com.luo.domain; public class User { private Integer userId; private String userName; private String userPassword; public Integer getUserId() { return userId; } public void setUserId(Integer userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPassword() { return userPassword; } public void setUserPassword(String userPassword) { this.userPassword = userPassword; } } ~~~ 8.2、com.luo.dao下添加UserDao.java文件： ~~~ package com.luo.dao; import com.luo.domain.User; public interface UserDao { /** * @param userId * @return User */ public User selectUserById(Integer userId); } ~~~ 8.3、com.luo.service下添加UserService.java接口和UserServiceImpl實現類： ~~~ package com.luo.service; import com.luo.domain.User; public interface UserService { User selectUserById(Integer userId); } ~~~ ~~~ package com.luo.service; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.luo.dao.UserDao; import com.luo.domain.User; @Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; public User selectUserById(Integer userId) { return userDao.selectUserById(userId); } } ~~~ ### 9、單元測試  9.1、com.luo.baseTest下添加SpringTestCase.java： ~~~ package com.luo.baseTest; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; //指定bean注入的配置文件 @ContextConfiguration(locations = { "classpath:application.xml" }) //使用標準的JUnit @RunWith注釋來告訴JUnit使用Spring TestRunner @RunWith(SpringJUnit4ClassRunner.class) public class SpringTestCase extends AbstractJUnit4SpringContextTests { } ~~~ 9.2、com.luo.service添加UserServiceTest.java： ~~~ package com.luo.service; import org.junit.Test; import org.springframework.beans.factory.annotation.Autowired; import com.luo.baseTest.SpringTestCase; import com.luo.domain.User; public class UserServiceTest extends SpringTestCase { @Autowired private UserService userService; @Test public void selectUserByIdTest(){ User user = userService.selectUserById(1); System.out.println(user.getUserName() + ":" + user.getUserPassword()); } } ~~~ 9.3、運行單元測試，UserServiceTest右鍵Run As –>Junit Test，運行結果：  下面加入springmvc，并轉換maven工程為web項目 ### 10、轉換成web項目： 如果上面webapp為空的，說明這個項目還不是web項目：  接下來打開如下頁面。將紅框里面的勾去掉，確定（OK）：  然后重新打開剛剛那個頁面，把Dynamic web Module勾上，就會看到紅框的內容，點擊：  然后配置如下：  那么webapp下就會生成這些東西：  ### 11、配置springmvc 11.1、pom.xml文件添加依賴，修改后配置如下： ~~~ <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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.luo</groupId> <artifactId>first_maven_project</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <!-- spring版本號 --> <spring.version>3.2.8.RELEASE</spring.version> <!-- junit版本號 --> <junit.version>4.10</junit.version> <!-- mybatis版本號 --> <mybatis.version>3.2.1</mybatis.version> </properties> <dependencies> <!-- 添加Spring依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId>

</dependency> <!--spring單元測試依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!--mybatis依賴 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.0</version> </dependency> <!-- mysql驅動包 --> <dependency> <groupId>mysql</groupId>

<version>6.0</version> <scope>provided</scope> </dependency> </dependencies> </project> ~~~ 其實也就增加了下面兩個 ~~~ <!-- javaee-api包 注意和項目使用的JDK版本對應 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> <!-- javaee-web-api包 注意和項目使用的JDK版本對應 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> ~~~ 11.2、在src/main/resource中添加springmvc文件夾，然后添加文件spring-mvc.xml，內容如下： ~~~ <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.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:annotation-driven /> <!-- 掃描controller（controller層注入） --> <context:component-scan base-package="com.luo.controller"/> <!-- 對模型視圖添加前后綴 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp"/> </beans> ~~~ 11.3、配置web.xml ~~~ <?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" id="WebApp_ID" version="2.5">

<!-- 內部錯誤 --> <error-code>500</error-code> <location>/WEB-INF/errorpage/500.jsp</location> </error-page> </web-app> ~~~ 11.4、添加index.jsp，在src/main/webapp/WEB-INF下新建一個文件夾view,添加一個index.jsp，內容如下：  ~~~ <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <html> <body> <h2>Hello World!</h2> 用戶名： ${user.userName}<br> 密碼：${user.userPassword}<br> </body> </html> ~~~ 11.5、寫controller  在src/main/java下新建一個包com.luo.controller.然后新建一個類UserController.java,其內容如下 ~~~ package com.luo.controller; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.luo.domain.User; import com.luo.service.UserService; @Controller public class UserController { @Resource private UserService userService; @RequestMapping("/") public ModelAndView getIndex(){ ModelAndView mav = new ModelAndView("index"); User user = userService.selectUserById(1); mav.addObject("user", user); return mav; } } ~~~ 11.6 運行！！！！完成！  ### 12、源碼下載
