网上有许多关于SpringMVC与Mybatis整合的实例，但是由于Mybaits-spring有好几种配置方式，这样看起来会觉得很乱，不知道哪个是对的，觉得很复杂(至少我的感觉是这样的)。把关于这块的学习过程记录下来，留作备注同时与大家分享交流。 工具 ：eclipse-luna、m
网上有许多关于springmvc与mybatis整合的实例，但是由于mybaits-spring有好几种配置方式，这样看起来会觉得很乱，不知道哪个是对的，觉得很复杂(至少我的感觉是这样的)。把关于这块的学习过程记录下来，留作备注同时与大家分享交流。

我们按照javaWeb项目在服务器中执行顺序(web项目首先加载web.xml文件)来说：
web.xml文件：在文件中，我们需要配置Spring的监听器ContextLoaderListener和SpringMVC的转发器DispatcherServlet，在web.xml中加入如下代码
org.springframework.web.context.ContextLoaderListener contextConfigLocation /WEB-INF/spring-applicationContext.xml encodingFilter org.springframework.web.filter.CharacterEncodingFilter encoding utf-8 encodingFilter *.yy encodingFilter *.jsp springmvc org.springframework.web.servlet.DispatcherServlet contextConfigLocation /WEB-INF/spring-dispatcher.xml 1 springmvc *.yy
在web.xml文件中，包含spring的配置文件：spring-applicationContext.xml ；SpringMVC的配置文件：spring-dispatcher.xml。
spring-dispatcher.xml文件：在文件中加入如下代码
org.springframework.web.servlet.view.JstlView
spring-applicationContext.xml文件：在文件中加入如下代码
${driverClassName}
${password}
${username}
${url}
文件中包含数据库连接池datasource的配置文件：jdbc.properties；spring与mybatis结合的配置文件：spring-mybatis.xml。spring-mybatis.xml文件的内容可以都放在spring.xml文件中，合成一个spring.xml文件和分成两个文件各有各的好处，看你的习惯
jdbc.properties文件：在文件中加入如下代码
driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/你的数据库名字 username=root password=root
spring-mybatis.xml文件：在文件中加入如下代码
文件中包含mybatis的配置文件：mybatis-config.xml
classpath:com/yy/mapper/**/*Mapper.xml
mybatis-config.xml文件：在文件中加入如下代码
配置文件到这里就配置完了，下面我们说一下controller、service、dao、model四层的代码
controller层：
package com.yy.controller;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.yy.model.Order;
import com.yy.service.BuyOrderService;
@Controller
@RequestMapping("buyOrder")
public class BuyOrderController {
@Resource
private BuyOrderService buyOrderService;
@RequestMapping("/addBuyOrder")
public ModelAndView addBuyOrder(HttpServletRequest resquest,HttpServletResponse response){
return new ModelAndView("/test");
}
@RequestMapping("/deleteBuyOrder")
public ModelAndView deleteBuyOrder(HttpServletRequest resquest,HttpServletResponse response){
return new ModelAndView("/test");
}
@RequestMapping("/getBuyOrderById")
public ModelAndView getBuyOrderById(int id,HttpServletRequest resquest,HttpServletResponse response){
Order order = buyOrderService.getBuyOrderById(id);
System.out.println(order.getId()+"+++"+order.getId());
return new ModelAndView("/test");
}
@RequestMapping("/getBuyOrderList")
public ModelAndView getBuyOrderList(HttpServletRequest resquest,HttpServletResponse response){
return new ModelAndView("/test");
}
}
service层
package com.yy.service;
import com.yy.model.Order;
public interface BuyOrderService {
public Order getBuyOrderById(int id);
public void addBuyOrder(Order order);
}
serviceImpl层package com.yy.service.Impl;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.yy.dao.BuyOrderDao;
import com.yy.model.Order;
import com.yy.service.BuyOrderService;
@Service
public class BuyOrderServiceImpl implements BuyOrderService{
@Resource
private BuyOrderDao buyOrderDao;
@Override
public Order getBuyOrderById(int id) {
return buyOrderDao.getBuyOrderById(id);
}
@Override
public void addBuyOrder(Order order) {
buyOrderDao.addBuyOrder(order);
}
}
dao层
package com.yy.dao;
import com.yy.model.Order;
public interface BuyOrderDao {
Order getBuyOrderById(int id);
void addBuyOrder(Order order);
}
mapper映射器类、映射器xml文件
映射器类文件
package com.yy.mapper;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.stereotype.Repository;
import com.yy.dao.BuyOrderDao;
import com.yy.model.Order;
@Repository
public class BuyOrderMapper extends SqlSessionDaoSupport implements BuyOrderDao {
@Override
public Order getBuyOrderById(int id) {
return (Order)this.getSqlSession().selectOne("com.yy.mapper.BuyOrderMapper.getBuyOrderById", id);
}
@Override
public void addBuyOrder(Order order) {
this.getSqlSession().insert("org.mybatis.spring.com.yy.mapper.addBuyOrder",order);
}
}
映射器xml文件model层
package com.yy.model;
import java.sql.Date;
public class Order {
private int id;
private String code;
private String username;
private String tel;
private String addresss;
private Date create_time;
public Order(){}
public Order(int id, String code, String username, String tel,String addresss, Date create_time) {
super();
this.id = id;
this.code = code;
this.username = username;
this.tel = tel;
this.addresss = addresss;
this.create_time = create_time;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
public String getAddresss() {
return addresss;
}
public void setAddresss(String addresss) {
this.addresss = addresss;
}
public Date getCreate_time() {
return create_time;
}
public void setCreate_time(Date create_time) {
this.create_time = create_time;
}
}
前台jsp文件：
index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
Insert title here
欢迎
test.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
Insert title here
test
数据sql文件：
DROP TABLE IF EXISTS `order1`;
CREATE TABLE `order1` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`code` varchar(20) DEFAULT NULL,
`username` varchar(20) DEFAULT NULL,
`tel` varchar(20) DEFAULT NULL,
`address` varchar(20) DEFAULT NULL,
`create_time` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of order1
-- ----------------------------
INSERT INTO `order1` VALUES ('1', '001', 'yy', '123456', '亚洲', '2014-12-16 16:19:51');
INSERT INTO `order1` VALUES ('2', '002', 'yyy', '654321', '欧洲', '2014-12-24 16:21:04');
到这里，代码就全部呈现了。哪里的细节你觉得不明白，欢迎交流
