一、准备工作

1. 首先创建一个表：

[sql] view
plain copy

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：

[sql] view
plain copy

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

[html] view
plain copy

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

[java] view
plain copy

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：

[java] view
plain copy

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

[java] view
plain copy

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

[java] view
plain copy

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

[html] view
plain copy

<?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：

[html] view
plain copy

<?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

[html] view
plain copy

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

[html] view
plain copy

<?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

[html] view
plain copy

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

[java] view
plain copy

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

[java] view
plain copy

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

[plain] view
plain copy

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：

[html] view
plain copy

<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">

<mybatis.version>3.2.1</mybatis.version>

</properties>

<dependencies>

<!-- 添加Spring依赖 -->

<dependency>

<groupId>javax</groupId>

<artifactId>javaee-web-api</artifactId>

</dependency>

</dependencies>

</project>

其实也就增加了下面两个

[html] view
plain copy

<!-- 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>

<!-- 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：

[html] view
plain copy

<?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：

[html] view
plain copy

<?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">

<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>

（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：

[html] view
plain copy

<%@ 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：

[java] view
plain copy

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
