maven+springMVC+mybatis 搭建过程

1.创建maven web 项目

　　maven 创建web应用命令：

　　　　mvn archetype:generate -DgroupId=[com.rom]包名 -DartifactId=[cpsrom]项目名 -DarchetypeArtifactId=maven-archetype-webapp;

2.pom.xml 导入相关依赖包

</dependency>

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>

3. 创建spring.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.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-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> 
<!-- 引入jdbc配置文件 -->
<context:property-placeholder location="classpath:system.properties"/>

<!-- 扫描文件（自动将servicec层注入） -->
<context:component-scan base-package="com.cater.rom"/>

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"  destroy-method="close" >
<property name="driverClass" value="${jdbc.driverClass}" />
<property name="jdbcUrl" value="${jdbc.jdbcUrl}" />
<property name="user" value="${jdbc.user}" />
<property name="password" value="${jdbc.password}" />
<property name="maxPoolSize" value="${jdbc.maxPoolSize}" />
<property name="minPoolSize" value="${jdbc.minPoolSize}" />
<property name="initialPoolSize" value="${jdbc.initialPoolSize}" />
<property name="maxIdleTime" value="${jdbc.maxIdleTime}" />
</bean>

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="1073741824" />
</bean>

<!-- 避免IE在ajax请求时，返回json出现下载 -->
<!--   <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean> -->

<!-- mybatis文件配置，扫描所有mapper文件
<bean id="sqlSessionFactory"  class="org.mybatis.spring.SqlSessionFactoryBean"
p:dataSource-ref="dataSource"
p:configLocation="classpath:mybatis-config.xml" />-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
</bean>
<!-- configLocation为mybatis属性 mapperLocations为所有mapper-->
<!-- p:mapperLocations="classpath:mapper/*.xml" -->
<!-- spring与mybatis整合配置，扫描所有dao -->

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"
p:basePackage="com.cater.rom"
p:sqlSessionFactoryBeanName="sqlSessionFactory"/>

<!-- 对数据源进行事务管理 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
p:dataSource-ref="dataSource"/>

<!-- 对模型视图添加前后缀 -->
<!--   <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/view/" p:suffix=".jsp"/>-->

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- <property name="viewClass">
<value>org.springframework.web.servlet.view.JstlView</value>
</property> -->
<property name="prefix" value="/"/>
<property name="suffix" value=".jsp"/>
</bean>

</beans>

4.创建mybatis.xml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>
<!-- 命名空间 -->
<typeAliases>
　　　　　　　　　　　　
<typeAlias alias="pmChannel" type="com.cater.rom.entity.PmChannel"/>
</typeAliases>

<!-- 映射map -->
<mappers>
<mapper resource="com/cater/rom/entity/PmChannelMapper.xml"/>
</mappers>
</configuration>

5.配置数据连接信息system.properties

#数据库连接
jdbc.jdbcUrl=jdbc:mysql://数据库ip地址:数据库端口号/数据库名称?autoReconnect=true&autoReconnectForPools=true
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=用户名
jdbc.password=连接密码

jdbc.maxPoolSize= 40
jdbc.minPoolSize= 1
jdbc.initialPoolSize= 1
jdbc.maxIdleTime=20

6、更改web.xml 配置文件

<?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" 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">
<display-name>Archetype Created Web Application</display-name>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 读取spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</context-param>
<!-- 设计路径变量值 -->
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>app.cater</param-value>
</context-param>

<!-- springMVC核心配置 -->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>

<!-- Spring字符集过滤器 -->
<filter>
<filter-name>SpringEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>SpringEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

7. 创建实体类配置文件

<?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">
<!--   指定要实现dao的全路径 方法名与id一致 -->
<mapper namespace="com.cater.rom.channel.dao.ChannelDao">
<resultMap type="com.cater.rom.entity.PmChannel" id="pmChannel">
<id column="id" property="id" />
<result column="name" property="name" />
<result column="password" property="password" />
<result column="contact_name" property="contactName" />
<result column="contact_phone" property="contactPhone" />
<result column="parent_name" property="parentName" />
<result column="status" property="status" />
<result column="roleid" property="roleid" />
<result column="grade" property="grade" />
</resultMap>
<!--  登录  id与dao 中的方法一致  -->
<select id="login"></select>

</mapper>
