idea创建spring+springMVC+MyBatis项目

第一步：打开idea–create new file–选中checkBox – 点击cocoon-22-archetype-webapp

第二步：导入jar包

 
    <dependency>

    <dependency>
      <groupId>com.alibabagroupId>
      <artifactId>fastjsonartifactId>
      <version>1.2.47version>
    dependency>


    
    <dependency>

      <artifactId>commons-fileuploadartifactId>
      <version>1.3.1version>
    dependency>

第三步：删除web-INF下面除了web.xml其余两个文件

第四步：编写连接数据库的外部文件 db.properties文件

db_url=jdbc:mysql://localhost:3306/stuMgr
db_driver=com.mysql.jdbc.Driver
db_name=root
db_pwd=root

第五步：编写springmvc.xml文件

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
       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-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd" default-autowire="byName">

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:db.properties"/>
    bean>
    <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="url" value="${db_url}" />
        <property name="driverClassName" value="${db_driver}"/>
        <property name="username" value="${db_name}"/>
        <property name="password" value="${db_pwd}"/>
    bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.mapper" />
        <property name="sqlSessionFactoryBeanName" value="sessionFactory" />

    bean>
    <bean name="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="configLocation" value="classpath:mybatis.xml" />
        <property name="typeAliasesPackage" value="com.entity" />
        <property name="mapperLocations" value="classpath:mapping/*.xml" />

    bean>
    <bean name="txManage"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

    bean>

    <bean class="org.springframework.web.multipart.commons.CommonsMultipartResolver" name="multipartResolver">
        <property name="maxUploadSize" value="5000000"/>
        <property name="defaultEncoding" value="UTF-8"/>
    bean>

    <tx:annotation-driven transaction-manager="txManage"/>

    <context:component-scan base-package="com.controller,com.service"/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>

    <mvc:resources mapping="/js/**" location="/js/"/>

    <mvc:annotation-driven/>
	
    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/book/*"/>
            <bean class="com.interceptor.MyInterceptor"/>
        mvc:interceptor>
    mvc:interceptors>
beans>

第六步：编写web.xml文件

 
    <filter>
        <filter-name>CharacterEncodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>utf-8param-value>
        init-param>
    filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>


    <servlet>
        <servlet-name>springmvcservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        <init-param>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:springmvc.xmlparam-value>
        init-param>
    servlet>
    <servlet-mapping>
        <servlet-name>springmvcservlet-name>
        <url-pattern>/url-pattern>
    servlet-mapping>

lue>classpath:springmvc.xml



springmvc
/

然后就可以写Mapper接口，写mapping里的数据库映射文件，写service,写controller,配置tomcat,就好了
