这篇文章主要讲解使用eclipse对Spirng+SpringMVC+Maven+Mybatis+MySQL项目搭建过程，包括里面步骤和里面的配置文件如何配置等等都会详细说明。

如果还没有搭建好环境（主要是Maven+MySQL的配置）的猿友可以参考博主以前的一篇文章：
http://blog.csdn.net/u013142781/article/details/50300233

接下来马上进入项目搭建过程：

1、创建表，并插入数据：

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工程创建



3、选择快速框架



4、输出项目名，包（Packaging，如果只是普通的项目，选jar就好了，如果是web项目就选war，这里是web项目，所以选择war）



5、创建好的目录如下：



6、添加包的依赖，编辑pom.xml文件添加如下依赖：

<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>

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（数据源配置文件）：

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">
<!--设置domain类和数据库中表的字段一一对应，注意数据库字段和domain类中的字段名称不致，此处一定要！-->
<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>
<!-- 查询单条记录 -->
<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>
<!--要是有多个配置文件，只需在这里继续添加即可 -->
</list>
</property>
</bean>

<!-- 配置数据源 -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<!-- 不使用properties来配置 -->
<!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/learning" />
<property name="username" value="root" />
<property name="password" value="christmas258@" /> -->
<!-- 使用properties来配置 -->
<property name="driverClassName">
<value>${jdbc_driverClassName}</value>
</property>
<property name="url">
<value>${jdbc_url}</value>
</property>
<property name="username">
<value>${jdbc_username}</value>
</property>
<property name="password">
<value>${jdbc_password}</value>
</property>
</bean>

<!-- 自动扫描了所有的XxxxMapper.xml对应的mapper接口文件，这样就不用一个一个手动配置Mpper的映射了，只要Mapper接口类和Mapper映射文件对应起来就可以了。 -->
<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="dataSource" ref="dataSource" />
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
<property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
<!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model"
/> -->
</bean>

<!-- 自动扫描注解的bean -->
<context:component-scan base-package="com.luo.service" />

</beans>

8、接口和类的配置：



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实现类：

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、单元测试



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" })
//使用标准的JUnit @RunWith注释来告诉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、运行单元测试，UserServiceTest右键Run As –>Junit Test，运行结果：



下面加入springmvc，并转换maven工程为web项目

10、转换成web项目：

如果上面webapp为空的，说明这个项目还不是web项目：



接下来打开如下页面。将红框里面的勾去掉，确定（OK）：



然后重新打开刚刚那个页面，把Dynamic web Module勾上，就会看到红框的内容，点击：



然后配置如下：



那么webapp下就会生成这些东西：



11、配置springmvc

11.1、pom.xml文件添加依赖，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版本号 -->
<spring.version>3.2.8.RELEASE</spring.version>
<!-- junit版本号 -->
<junit.version>4.10</junit.version>
<!-- mybatis版本号 -->
<mybatis.version>3.2.1</mybatis.version>
</properties>

<dependencies>
<!-- 添加Spring依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>

<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-aspects</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>

<!--单元测试依赖 -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
<scope>test</scope>
</dependency>

<!--spring单元测试依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
<scope>test</scope>
</dependency>

<!--mybatis依赖 -->
<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驱动包 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.29</version>
</dependency>

<!-- javaee-api包 注意和项目使用的JDK版本对应 -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>

<!-- javaee-web-api包 注意和项目使用的JDK版本对应 -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>

</dependencies>

</project>

其实也就增加了下面两个

<!-- javaee-api包 注意和项目使用的JDK版本对应 -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>

<!-- javaee-web-api包 注意和项目使用的JDK版本对应 -->
<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文件夹，然后添加文件spring-mvc.xml，内容如下：

<?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 />
<!-- 扫描controller（controller层注入） -->
<context:component-scan base-package="com.luo.controller"/>

<!-- 对模型视图添加前后缀 -->
<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">
<display-name>Archetype Created Web Application</display-name>
<!-- 起始欢迎界面 -->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!-- 读取spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:application.xml</param-value>
</context-param>
<!-- 设计路径变量值 -->
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>springmvc.root</param-value>
</context-param>

<!-- Spring字符集过滤器 -->
<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>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- springMVC核心配置 -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!--spingMVC的配置路径  -->
<param-value>classpath:springmvc/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 拦截设置 -->
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- 错误跳转页面 -->
<error-page>
<!-- 路径不正确 -->
<error-code>404</error-code>
<location>/WEB-INF/errorpage/404.jsp</location>
</error-page>
<error-page>
<!-- 没有访问权限，访问被禁止 -->
<error-code>405</error-code>
<location>/WEB-INF/errorpage/405.jsp</location>
</error-page>
<error-page>
<!-- 内部错误 -->
<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下新建一个文件夹view,添加一个index.jsp，内容如下：



<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<body>
<h2>Hello World!</h2>
用户名： ${user.userName}<br>
密码：${user.userPassword}<br>
</body>
</html>

11.5、写controller



在src/main/java下新建一个包com.luo.controller.然后新建一个类UserController.java,其内容如下

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 运行！！！！完成！
