Spring4.2.4+Mybatis3.4.5+SpringMVC4.2.4+PageHelper 的整合

1、开发环境

Eclipse 4.6.3

Windows 64位

Tomcat 7.0

2、项目结构

3、整合思路，首先整合Spring和Mybatis，把Mybatis的Sqlsesson和SqlsessonFactory 交给Spring管理，利用mybatis-spring 1.3.0 jar来无缝对接

1、导入mybatis 需要的jar

2、导入Spring需要的jar

3、导入数据源包，利用阿里巴巴数据源

4、导入spring日志支持jar

5、导入分页插件包

6、导入Springmvc需要的jar

7、导入标签jar包

4、编写实体

package com.cn.bean;

public class Goods {
	private Integer id;
	private String name;
	private String type;

	public void setId(Integer id) {
		this.id = id;
	}

	public Integer getId() {
		return id;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getName() {
		return name;
	}

	public void setType(String type) {
		this.type = type;
	}

	public String getType() {
		return type;
	}

	@Override
	public String toString() {
		return "Goods [id=" + id + ", name=" + name + ", type=" + type + "]";
	}

}

5、编写mapper接口和映射文件

package com.cn.mapper;

import java.util.List;

import com.cn.bean.Goods;

/**
 * @ClassName GoodsMapper
 * @Description TODO(这里用一句话描述这个类的作用)
 * @author hasee
 * @Date 2017年12月1日 下午5:46:25
 * @version 1.0.0
 */
public interface GoodsMapper {

	List<Goods> findAll();

	void save(Goods goods);

}

<?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.cn.mapper.GoodsMapper">

  <select id="findAll" resultType="goods">
     select * from goods
  </select>
  
  <insert id="save" parameterType="goods">
      insert into goods(name,type) values(#{name},#{type})
  </insert>

</mapper>

6、编写服务层

package com.cn.service;

import java.util.List;

import com.cn.bean.Goods;
import com.github.pagehelper.PageInfo;

/**
 * @ClassName GoodsService
 * @Description TODO(这里用一句话描述这个类的作用)
 * @author hasee
 * @Date 2017年12月1日 下午5:49:30
 * @version 1.0.0
 */
public interface GoodsService {

	List<Goods> queryAll();

	void add(Goods goods);

	PageInfo<Goods> page(int currentPage);

}

package com.cn.service;

import java.util.List;

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

import com.cn.bean.Goods;
import com.cn.mapper.GoodsMapper;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;

/**
 * @ClassName GoodsServiceImpl
 * @Description TODO(这里用一句话描述这个类的作用)
 * @author hasee
 * @Date 2017年12月1日 下午5:50:11
 * @version 1.0.0
 */
@Transactional
@Service
public class GoodsServiceImpl implements GoodsService {

	@Autowired
	private GoodsMapper mapper;

	@Override
	public List<Goods> queryAll() {
		// TODO Auto-generated method stub
		return mapper.findAll();
	}

	@Override
	public void add(Goods goods) {
		mapper.save(goods);
	}

	@Override
	public PageInfo<Goods> page(int currentPage) {

		PageHelper.startPage(currentPage, 3);
		List<Goods> list = mapper.findAll();
		PageInfo<Goods> pageInfo = new PageInfo<>(list);

		return pageInfo;
	}

}

7、编写Myatis配置文件

<?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>

	<!-- 全局设置 -->
	<settings>
		<setting name="autoMappingBehavior" value="FULL" /> <!-- 开启全部自动映射，包含嵌套查询 -->
		<!-- 打开懒加载的开关 -->
		<setting name="lazyLoadingEnabled" value="true" />
	</settings>


</configuration>

8、编写数据库连接配置参数

mybatis.driver=com.mysql.jdbc.Driver
mybatis.url=jdbc:mysql://localhost:3308/mybatis
mybatis.username=root
mybatis.password=123456

#配置信息
mybatis.maxActive=20
mybatis.initialSize=5
mybatis.minIdle=3

9、编写日志配置文件

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
 
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File =org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/spring.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout =org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-ddHH\:mm\:ss}][%c]%m%n

log4j.category.org.springframework.beans.factory=DEBUG

# MyBatis logging configuration...
log4j.logger.org.mybatis.example.BlogMapper=TRACE

10、编写Spring-mybatis整合配置文件

<?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:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" 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.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

	<!-- 开启组件扫描 -->
	<context:component-scan base-package="com.cn.service"></context:component-scan>

	<!--加载数据源配置信息 -->
	<context:property-placeholder location="classpath:db.properties" />

	<!--配置数据源 -->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
		<property name="driverClassName" value="${mybatis.driver}"></property>
		<property name="url" value="${mybatis.url}"></property>
		<property name="username" value="${mybatis.username}"></property>
		<property name="password" value="${mybatis.password}"></property>

		<!-- 选配信息 -->
		<property name="maxActive" value="${mybatis.maxActive}"></property>
		<property name="initialSize" value="${mybatis.initialSize}"></property>
		<property name="minIdle" value="${mybatis.minIdle}"></property>

	</bean>


	<!-- 配置sqlsessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="configLocation" value="classpath:mybatis-config.xml"></property>
		<!--扫描映射文件 -->
		<property name="mapperLocations" value="classpath:com/cn/mapper/*.xml"></property>
		<!--设置别名 -->
		<property name="typeAliasesPackage" value="com.cn.bean"></property>
		
         <!-- 插件 -->
		<property name="plugins">
			<array>
				<bean class="com.github.pagehelper.PageInterceptor">
					<property name="properties">
						<!-- config params as the following -->
						<value>
							helperDialect=mysql
						</value>
					</property>
				</bean>
			</array>
		</property>
	</bean>

	<!--配置扫描Mapper接口 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
		<property name="basePackage" value="com.cn.mapper"></property>
	</bean>

	<!--配置JDBC事务管理 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>

	<!--开启注解事务 -->
	<tx:annotation-driven transaction-manager="transactionManager" />

</beans>

11、编写控制器

package com.cn.controller;

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

import com.cn.service.GoodsService;

/**
 * @ClassName IndexController
 * @Description TODO(这里用一句话描述这个类的作用)
 * @author hasee
 * @Date 2017年12月6日 上午9:44:24
 * @version 1.0.0
 */
@Controller
public class IndexController {

	@Autowired
	private GoodsService service;

	@RequestMapping("/index.do")
	public String queryAll(Model model) {
		model.addAttribute("goods", service.queryAll());
		return "index";
	}

	@RequestMapping("/indexPage.do")
	public String queryPage(Model model, int page) {
		model.addAttribute("goods", service.page(page));
		return "index";
	}

}

12、编写springmvc的配置文件

<?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: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.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<!--组件扫描 -->
	<context:component-scan base-package="com.cn.controller"></context:component-scan>

     <!--导入Spring-mybatis配置文件  -->
      <import resource="spring-mybatis.xml"/>


	<!--视图解析器 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>



</beans>

13、编写web.xml配置前端控制器

<?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"
	id="WebApp_ID" version="3.0">
	<display-name>SSM-Base</display-name>
	<!-- The front controller of this Spring Web application, responsible for 
		handling all application requests -->
	<servlet>
		<servlet-name>springDispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>


	
</web-app>

14、前端显示页面

<?xml version="1.0" encoding="UTF-8" ?>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>
<title>首页</title>
</head>
<body>
			<table border="1px" cellspacing="0">
				<tr>
					<th>商品编号</th>
					<th>商品名称</th>
					<th>商品类型</th>
				</tr>
				<c:forEach var="good" items="${goods.list }">
					<tr>
						<td>${good.id }</td>
						<td>${good.name }</td>
						<td>${good.type }</td>
					</tr>
				</c:forEach>
			</table>
			<div>
			     总页数:${goods.pages}/当前页：${goods.pageNum }
			    <a href="indexPage.do?page=${goods.prePage}">上一页</a>
			    <a href="indexPage.do?page=${goods.nextPage}">下一页</a>
			</div>
</body>
</html>
