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

        <!-- springframe end -->

        <!-- http://mvnrepository.com/artifact/commons-fileupload/commons-fileupload -->
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.3.1</version>
        </dependency>

        <!-- mybatis核心包 -->

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/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
      http://www.springframework.org/schema/tx

      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>
