1、创建maven项目，webapp。把下面依赖复制到pom.xml文件中 
        <properties>  
            <!-- spring版本号 -->  
            <spring.version>4.0.2.RELEASE</spring.version>

            </dependency>               
        </dependencies>

2、创建jdbc.properties文件，配置MySQL数据库的基本信息

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/erp2
username=root
password=123456

3、修改web.xml文件 

<?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"  
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"  
    version="3.0"> 
  <display-name>Archetype Created Web Application</display-name>
   <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:applicationContext.xml</param-value>  
    </context-param>  
    <!-- 编码过滤器 -->

            <param-name>encoding</param-name>  
            <param-value>UTF-8</param-value>  
        </init-param>  
    </filter>  
    <filter-mapping>  
        <filter-name>encodingFilter</filter-name>  
        <url-pattern>*.action</url-pattern>  
        <url-pattern>*.do</url-pattern>  
        <url-pattern>*.view</url-pattern>  
    </filter-mapping>  
    <!-- Spring监听器 -->  
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  
    <!-- 防止Spring内存溢出监听器 -->  
    <listener>  
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>  
    </listener>  
  
    <!-- Spring MVC servlet -->  
    <servlet>  
        <servlet-name>SpringMVC</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        </init-param>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>SpringMVC</servlet-name>  
        <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->  
        <url-pattern>/</url-pattern>  
    </servlet-mapping>  
    <welcome-file-list>  
        <welcome-file>/index.jsp</welcome-file>  
    </welcome-file-list>  
  
</web-app>

3、创建spring-mybatis.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:p="http://www.springframework.org/schema/p"  
    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-3.1.xsd    
                        http://www.springframework.org/schema/context    
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd    
                        http://www.springframework.org/schema/mvc    
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">  
    <!-- 自动扫描 -->  
    <context:component-scan base-package="cn.zkz" />  
    <!-- 引入配置文件 -->  
    <bean id="propertyConfigurer"  
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
        <property name="location" value="classpath:jdbc.properties" />

        <property name="url" value="${url}" />  
        <property name="username" value="${username}" />  
        <property name="password" value="${password}" />  
         
    </bean>  
  
    <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->  
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
        <property name="dataSource" ref="dataSource" />  
        <!-- 自动扫描mapping.xml文件 -->  
        <property name="mapperLocations" value="classpath:cn/zkz/pojo/*.xml"></property>  
    </bean>  
  
    <!-- DAO接口所在包名，Spring会自动查找其下的类 -->  
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
        <property name="basePackage" value="cn.zkz.dao.impl" />  
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>  
    </bean>  
  
    <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->  
    <bean id="transactionManager"  
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
        <property name="dataSource" ref="dataSource" />  
    </bean>  
  
</beans>

3、创建spring-mvc.xml文件 

<?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:p="http://www.springframework.org/schema/p"  
    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-3.1.xsd    
                        http://www.springframework.org/schema/context    
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd    
                        http://www.springframework.org/schema/mvc    
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">  
    <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->  
    <context:component-scan base-package="cn.zkz.controller" />  
    <!--避免IE执行AJAX时，返回JSON出现下载文件 -->  
    <bean id="mappingJacksonHttpMessageConverter"  
        class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  
        <property name="supportedMediaTypes">  
            <list>  
                <value>text/html;charset=UTF-8</value>  
            </list>  
        </property>  
    </bean>  
    <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->  
    <bean  
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  
        <property name="messageConverters">  
            <list>

            </list>  
        </property>  
    </bean>  
    <!-- 定义跳转的文件的前后缀 ，视图模式配置-->  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->  
        <property name="prefix" value="/WEB-INF/jsp/" />  
        <property name="suffix" value=".jsp" />  
    </bean>  
      
    <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->  
    <bean id="multipartResolver"

        <property name="maxInMemorySize" value="40960" />    
    </bean>   
  
</beans>

4、创建log4j.xml 

 log4j.rootLogger=INFO,Console,File
#\u5B9A\u4E49\u65E5\u5FD7\u8F93\u51FA\u76EE\u7684\u5730\u4E3A\u63A7\u5236\u53F0

log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

5、创建applicationContext.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"

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
">
    <!-- 1.配置jdbc文件 -->
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="locations" value="classpath:jdbc.properties"/>
    </bean>

    <!-- 2.扫描的包路径，这里不扫描被@Controller注解的类 --><!--使用<context:component-scan/> 可以不在配置<context:annotation-config/> -->
    <context:component-scan base-package="org.ssm.dufy">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <bean class="cn.zkz.dao.impl.EmpDaoImpl" id="empDao">
    	<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
    </bean>
    <bean class="cn.zkz.service.impl.EmpServiceImpl" id="empService"></bean>
    
    <import resource="classpath:spring-mybatis.xml" />
    
</beans>

6、创建controller ，包名cn.zkz.controller 

package cn.zkz.controller;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.zkz.pojo.EmpModel;
import cn.zkz.service.EmpService;

@Controller
@RequestMapping("/emp")
public class EmpController {
	@Resource  
    private EmpService empService;
	@RequestMapping("/showEmp")  
    public String toIndex(HttpServletRequest request,Model model){  
        long empUuid = Integer.parseInt(request.getParameter("id"));  
        EmpModel em = this.empService.getEmById(empUuid);
        model.addAttribute("em", em);  
        return "emp";  
    }   
}

7、service层 

package cn.zkz.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import cn.zkz.dao.EmpDao;
import cn.zkz.pojo.EmpModel;
import cn.zkz.service.EmpService;

public class EmpServiceImpl implements EmpService{

	@Resource
    private EmpDao empDao;

	@Override
	public EmpModel getEmById(Long empUuid) {
		
		return this.empDao.selectByPrimaryKey(empUuid); 
	}

}

8、dao层 

package cn.zkz.dao.impl;

import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;

import cn.zkz.dao.EmpDao;
import cn.zkz.pojo.EmpModel;

public class EmpDaoImpl implements EmpDao {

	private SqlSessionFactory sqlSessionFactory;
	public SqlSessionFactory getSqlSessionFactory() {
		return sqlSessionFactory;
	}
	public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {
		this.sqlSessionFactory = sqlSessionFactory;
	}

	@Override
	public EmpModel selectByPrimaryKey(long empUuid) {

		// 创建SqlSession
		SqlSession sqlSession = this.sqlSessionFactory.openSession();

		// 根据id查询用户信息
		EmpModel em = sqlSession.selectOne("findUserById", empUuid);

		return em;
	}

}

9、pojo 

package cn.zkz.pojo;

public class EmpModel {

	private Long uuid;
	private String username;
	private String password;
	private String name;
	private String tele;
	private Integer gerder;
	public Long getUuid() {
		return uuid;
	}
	public void setUuid(Long uuid) {
		this.uuid = uuid;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getTele() {
		return tele;
	}
	public void setTele(String tele) {
		this.tele = tele;
	}
	public Integer getGerder() {
		return gerder;
	}
	public void setGerder(Integer gerder) {
		this.gerder = gerder;
	}
	
	
}

10、EmpModelMapper.xml 

<?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">
<!-- namespace命名空间，为了对sql语句进行隔离，方便管理 ，mapper开发dao方式，使用namespace有特殊作用
mapper代理开发时将namespace指定为mapper接口的全限定名
 -->
<mapper namespace="cn.zkz.pojo.EmpModel">

	<!-- 根据id查询用户信息 -->
	<!-- 
		id：唯一标识 一个statement
		#{}：表示 一个占位符，如果#{}中传入简单类型的参数，#{}中的名称随意
		parameterType：输入 参数的类型，通过#{}接收parameterType输入 的参数
		resultType：输出结果 类型，不管返回是多条还是单条，指定单条记录映射的pojo类型
	 -->
	<select id="findUserById" parameterType="long" resultType="cn.zkz.pojo.EmpModel" >
		SELECT * FROM tbl_emp WHERE uuid= #{id}
	
	</select>
	



</mapper>
