摘要：本文主要讲了如何使用Maven来搭建Spring+Mybatis+SpringMVC+MySql的搭建实例，文章写得很详细，有代码有图片，最后也带有运行的效果。如果报的错误太多并且难以修改，可以参照本文档最后提供的源码。
一、准备工作
CREATE TABLE `t_user` (
`USER_ID` int(11) NOT NULL AUTO_INCREMENT,
`USER_NAME` char(30) NOT NULL,
`USER_PASSWORD` char(10) NOT NULL,
`USER_EMAIL` char(30) 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, USER_EMAIL) VALUES (1, 'cehkongfu', '1234567@', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (2, 'evan', '123', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (3, 'kaka', 'cadg', '[email protected]');
二、工程创建
1、Maven工程创建
（1）新建
（2）选择快速框架
（3）输出项目名，包，记得选war(表示web项目，以后可以spingMVC连起来用)
（4）创建好之后
目录如下：
项目报错，将后文中的pom.xml内容拷贝进来，然后执行maven->Update Project错误即可消失。
三、sping+mybatis配置
1、整个工程目录如下：
2、POM文件

（1）User.java
对应数据库中表的字段，放在src/main/java下的包com.ceh.domain
package com.ceh.domain;
/**
* User映射类
*
* @author cehkongfu
* @time 2018年3月12日
*/
public class User {
private Integer userId;
private String userName;
private String userPassword;
private String userEmail;
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;
}
public String getUserEmail() {
return userEmail;
}
public void setUserEmail(String userEmail) {
this.userEmail = userEmail;
}
@Override
public String toString() {
return "User [userId=" + userId + ", userName=" + userName
+ ", userPassword=" + userPassword + ", userEmail=" + userEmail
+ "]";
}
}
（2）UserDao.java
Dao接口类，用来对应mapper文件。放在src/main/java下的包com.ceh.dao,内容如下：
package com.ceh.dao;
import com.ceh.domain.User;
/**
* 功能概要：User的DAO类
*
* @author cehkongfu
* @since 2018年3月12日
*/
public interface UserDao {
/**
* @author cehkongfu
* @since 2018年3月12日
* @param userId
* @return
*/
public User selectUserById(Integer userId);
}
（2）UserService.java和UserServiceImpl.java
service接口类和实现类，放在src/main/java下的包com.ceh.service,内容如下：
UserService.java
package com.ceh.service;
import com.ceh.domain.User;
/**
* 功能概要：UserService接口类
*
* @author cehkongfu
* @since 2018年3月12日
*/
public interface UserService {
User selectUserById(Integer userId);
}
UserServiceImpl.java
package com.ceh.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.ceh.dao.UserDao;
import com.ceh.domain.User;
/**
* 功能概要：UserService实现类
*
* @author cehkongfu
* @since 2018年3月12日
*/
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao;
public User selectUserById(Integer userId) {
return userDao.selectUserById(userId);
}
}
（4）mapper文件
用来和dao文件对应，放在src/main/java下的com.ceh.mapper包下
<mapper namespace="com.ceh.dao.UserDao">
<resultMap id="BaseResultMap" type="com.ceh.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" />
<result column="USER_EMAIL" property="userEmail" jdbcType="CHAR" />
resultMap>
<select id="selectUserById" parameterType="int" resultMap="BaseResultMap">
SELECT * FROM t_user WHERE USER_ID = #{userId}
select>
mapper>
4、资源配置-------src/main/resources
目录如下：
(1)mybatis配置文件
因为都被放到application.xml中去了,放在src/main/resources下的mybatis文件夹下, 虽然这里没有什么内容，但是可以用于后面功能扩展。
mybatis-config.xml内容如下：
<configuration>
configuration>
（2）数据源配置jdbc.properties
放在src/main/resources下的properties文件夹下
jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/new
jdbc_username=root
jdbc_password=sorry
（3）Spring配置
这是最重要的：application.xml内容如下
<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-3.2.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">

<value>classpath:properties/*.propertiesvalue>
list>
property>
bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<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>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ceh.dao" />
bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" value="classpath*:com/ceh/mapper/*.xml"/>
<property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
bean>
<context:component-scan base-package="com.ceh.service" />
beans>
（4）日志打印log4j.properties
就放在src/main/resources
log4j.rootLogger=DEBUG,Console,Stdout
#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
log4j.appender.Stdout = org.apache.log4j.DailyRolcehgFileAppender
log4j.appender.Stdout.File = D://logs/log.log
log4j.appender.Stdout.Append = true
log4j.appender.Stdout.Threshold = DEBUG
log4j.appender.Stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.Stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
四、单元测试
上面的配置完好，接下来就是测验成功
整个目录 如下：
（1）测试基类
package com.ceh.baseTest;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
/**
* 功能概要：
*
* @author cehkongfu
* @since 2018年3月12日
*/
//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 abstract class SpringTestCase extends AbstractJUnit4SpringContextTests{
protected Logger logger = LoggerFactory.getLogger(getClass());
}
（2）测试类
package com.ceh.service;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import com.ceh.baseTest.SpringTestCase;
import com.ceh.domain.User;
/**
* 功能概要：UserService单元测试
*
* @author cehkongfu
* @since 2015年9月28日
*/
public class UserServiceTest extends SpringTestCase {
@Autowired
private UserService userService;
Logger logger = Logger.getLogger(UserServiceTest.class);
@Test
public void selectUserByIdTest(){
User user = userService.selectUserById(10);
logger.debug("查找结果" + user);
}
}
选中selectUserByIdTest，然后右键如下运行
重要打印的结果
数据库：
程序成功运行，并且结果正确！
到这里配置好spring+mybatis+mysql
======================================
这里开始添加spirngMVC，并转换maven工程为web项目
五、转换web工程
接上面的工程接着说，此时要加spingMVC之前，工程得再稍微转换下
此时webapp下的结果还没有显示出来，因为此时我们还没有配置此的项目为web项目
再次进去Properties配置，如下图所示：如果没有显示如下，那就先把dynamic web module的√给去掉，然后重新再打开这个
进入，然后输入如下内容
确定OK之后,webapp下面就会自动生成一些文件，如下
六、配置SpringMVC
（1）修改POM文件，增加了一此内容, 增加了下面两个：
<dependency>
<groupId>javaxgroupId>
<artifactId>javaee-apiartifactId>
<version>6.0version>
<scope>providedscope>
dependency>
<dependency>
<groupId>javaxgroupId>
<artifactId>javaee-web-apiartifactId>
<version>6.0version>
<scope>providedscope>
dependency>
(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：
<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">
<context:component-scan base-package="com.ceh.controller"/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/view/" p:suffix=".jsp"/>
beans>
（3）配置web,xml
目录如下 ：
这里是关键，web.xml是用来起动sping、spingMVC
放在src/main/webapp/WEB-INF下。内容如下：
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

<location>/WEB-INF/errorpage/500.jsplocation>
error-page>
web-app>
（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"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h2>Hello World!</h2>
${user.userId}<br>
${user.userName}<br>
${user.userPassword}<br>
${user.userEmail}<br>
</body>
</body>
</html>
（5）最后就是controller的书写了
在src/main/java下新建一个包com.ceh.controller.然后新建一个类UserController.java,其内容如下：
package com.ceh.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.ceh.domain.User;
import com.ceh.service.UserService;
/**
* 功能概要：UserController
*
* @author cehkongfu
* @since 2018年3月12日
*/
@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;
}
}
（6）最后的运行！
最后，就是成果了，已经全部都配置好了。我们可以开始以web工程运行了！
然后一路next
接下来控制台就会打印日志出来了！如下
打印浏览器，输入网址：http://localhost:8088/ssmMaven/
