2 src下建java包和类：

实体类：Employee.java

package com.springjdbc.entities;

/**
 * Created by wanggenshen_sx on 2016/12/23.
 */
public class Employee {

   private int id;
   private String lastName;
   private String email;

   public int getId() {
      return id;
   }
   public void setId(int id) {
      this.id = id;
   }
   public String getLastName() {
      return lastName;
   }
   public void setLastName(String lastName) {
      this.lastName = lastName;
   }
   public String getEmail() {
      return email;
   }
   public void setEmail(String email) {
      this.email = email;
   }
   @Override
   public String toString() {
      return "Employee [id=" + id + ", lastName=" + lastName + ", email="
            + email+" ]" ;
   }
}

持久层类：EmployeeDao.java

这里注入JdbcTemplate,使用SpringJDBC框架。

package com.springjdbc.dao;

import com.springjdbc.entities.Employee;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.stereotype.Repository;

/**
 * Created by wanggenshen_sx on 2016/12/23.
 */
@Repository
public class EmployeeDao {
   @Autowired
   private JdbcTemplate jdbcTemplate;

   public Employee get(int id){
      String sql="SELECT id, lastName,email FROM employee WHERE id=?";
      RowMapper rowMapper=new BeanPropertyRowMapper<>(Employee.class);
      Employee employee=jdbcTemplate.queryForObject(sql, rowMapper,id);

      return employee;
   }
}

控制器：EmployeeController.java

package com.springjdbc.controller;

import com.springjdbc.dao.EmployeeDao;
import com.springjdbc.entities.Employee;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import java.util.List;
import java.util.Map;

/**
 * Created by wanggenshen_sx on 2016/12/23.
 */
@Controller
public class EmployeeController {

   private ApplicationContext ctx=null;
   private JdbcTemplate jdbcTemplate=null;
   private EmployeeDao employeeDao ;
   private NamedParameterJdbcTemplate namedParameterJdbcTemplate=null;
   {
      ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
      jdbcTemplate =(JdbcTemplate) ctx.getBean("jdbcTemplate");
      employeeDao = ctx.getBean(EmployeeDao.class);
      namedParameterJdbcTemplate=(NamedParameterJdbcTemplate) ctx.getBean("namedParameterJdbcTemplate");

   }

   @RequestMapping(value = "/listAllEmployee",method = RequestMethod.GET)
   public String list(Map,Object> map){
      String sql="SELECT id, lastName,email FROM employee";
      RowMapper rowMapper=new BeanPropertyRowMapper<>(Employee.class);
      List employees=jdbcTemplate.query(sql, rowMapper);
      map.put("employees",employees);
      return "list";
   }
}

3  配置sping和spingmvc的配置文件：

applicationContext.xml

xml version="1.0" encoding="UTF-8"?>
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:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">


    <context:component-scan base-package="com.springjdbc.dao">context:component-scan>

    
    <context:property-placeholder location="classpath:db.properties"/>
    
    id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        name="user" value="${jdbc.user}">
        name="password" value="${jdbc.password}">
        name="driverClass" value="${jdbc.driverClass}">
        name="jdbcUrl" value="${jdbc.jdbcUrl}">

        name="initialPoolSize" value="${jdbc.initPoolSize}">
        name="maxPoolSize" value="${jdbc.maxPoolSize}">

    

    
    id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        name="dataSource" ref="dataSource">
    

    
    id="namedParameterJdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
        ref="dataSource">
    

    
    id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        name="dataSource" ref="dataSource">
    

    
    transaction-manager="transactionManager"/>

    
    

springmvc-servlet.xml

xml version="1.0" encoding="UTF-8"?>
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: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-3.1.xsd">
    <mvc:annotation-driven />
    <mvc:default-servlet-handler/>

    
    <context:component-scan base-package="com.springjdbc.controller" />

    
    id="viewResolverCommon" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        name="prefix" value="/WEB-INF/views/"/>
        name="suffix" value=".jsp"/>
        name="viewClass"  value="org.springframework.web.servlet.view.JstlView" />
    

4 配置web.xml

web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >
xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

  
  
    springmvc-servlet
    org.springframework.web.servlet.DispatcherServlet
    
      contextConfigLocation
      classpath:springmvc-servlet.xml
    

    1
  

  
    springmvc-servlet
    /
  

  
    contextConfigLocation
    classpath:applicationContext.xml
  

  
    org.springframework.web.context.ContextLoaderListener
  

5 建显示页面list.jsp

${emp.id}

项目结构：
