一、准备工作

  1. 首先创建一个表:
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

随便插入一些数据:

INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (1, '林炳文', '1234567@', 'ling20081005@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (2, 'evan', '123', 'fff@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (3, 'kaka', 'cadg', 'fwsfg@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (4, 'simle', 'cscs', 'fsaf@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (5, 'arthur', 'csas', 'fsaff@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (6, '小德', 'yuh78', 'fdfas@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (7, '小小', 'cvff', 'fsaf@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (8, '林林之家', 'gvv', 'lin@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (9, '林炳文Evankaka', 'dfsc', 'ling2008@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (10, 'apple', 'uih6', 'ff@qq.com');

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:

(5)检查下

这三个地方JDK的版本一定要一样!!!!

三、sping+mybatis配置

1、整个工程目录如下:

2、POM文件

<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">

		</dependency>
	</dependencies>

</project>

3、java代码-------src/main/java

目录如下:

(1)User.java

对应数据库中表的字段,放在src/main/java下的包com.lin.domain

package com.lin.domain;

/**
 * User映射类
 * 
 * @author linbingwen
 * @time 2015.5.15
 */
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.lin.dao,内容如下:

package com.lin.dao;

import com.lin.domain.User;

/**
 * 功能概要:User的DAO类
 * 
 * @author linbingwen
 * @since 2015年9月28日
 */
public interface UserDao {
	/**
	 * 
	 * @author linbingwen
	 * @since 2015年9月28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.lin.service,内容如下:

UserService.java

package com.lin.service;

import org.springframework.stereotype.Service;

import com.lin.domain.User;

/**
 * 功能概要:UserService接口类
 * 
 * @author linbingwen
 * @since  2015年9月28日 
 */
public interface UserService {
	User selectUserById(Integer userId);

}

UserServiceImpl.java

package com.lin.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.lin.dao.UserDao;
import com.lin.domain.User;

/**
 * 功能概要:UserService实现类
 * 
 * @author linbingwen
 * @since  2015年9月28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.lin.mapper包下

<?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.lin.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.lin.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>
	<!-- 查询单条记录 -->
	<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

这里没有什么内容,因为都被放到application.xml中去了,放在src/main/resources下的mybatis文件夹下

mybatis-config.xml内容如下:

<?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>

(2)数据源配置jdbc.properties

放在src/main/resources下的propertiesy文件夹下

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/learning
jdbc_username=root
jdbc_password=christmas258@

(3)Spring配置

这是最重要的:application.xml内容如下

<?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.lin.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*:com/lin/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.lin.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.DailyRollingFileAppender  
log4j.appender.Stdout.File = E://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.lin.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 linbingwen
 * @since  2015年9月28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.lin.service;

import org.apache.log4j.Logger;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

import com.lin.baseTest.SpringTestCase;
import com.lin.domain.User;

/**
 * 功能概要:UserService单元测试
 * 
 * @author linbingwen
 * @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

输出结果:

重要打印的结果

这里

2015-09-28 15:20:15,129 [main] DEBUG [com.lin.dao.UserDao.selectUserById] - ==>  Preparing: SELECT * FROM t_user WHERE USER_ID = ? 
2015-09-28 15:20:15,160 [main] DEBUG [com.lin.dao.UserDao.selectUserById] - ==> Parameters: 10(Integer)
2015-09-28 15:20:15,160 [main] DEBUG [org.mybatis.spring.SqlSessionUtils] - Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@6b64bff9]
2015-09-28 15:20:15,160 [main] DEBUG [org.springframework.jdbc.datasource.DataSourceUtils] - Returning JDBC Connection to DataSource
2015-09-28 15:20:15,160 [main] DEBUG [com.lin.service.UserServiceTest] - 查找结果User [userId=10, userName=apple, userPassword=uih6, userEmail=ff@qq.com]

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,新的POM文件如下:

<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.lin</groupId>
	<artifactId>ssm_project</artifactId>

	<packaging>war</packaging>
	<properties>

		<!-- junit版本号 -->
		<junit.version>4.10</junit.version>
		<!-- mybatis版本号 -->
		<mybatis.version>3.2.1</mybatis.version>
	</properties>

	<dependencies>

			<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>

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

(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:

<?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>

    </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"%>
<html>
<body>
<h2>Hello World!</h2>
 ${user.userId}<br>
 ${user.userName}<br>
 ${user.userPassword}<br>
 ${user.userEmail}<br>
</body>
</html>

(5)最后就是controller的书写了

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

package com.lin.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.lin.domain.User;
import com.lin.service.UserService;

/**
 * 功能概要:UserController
 * 
 * @author linbingwen
 * @since  2015年9月28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
