注意修改spring文件夹下的配置文件，因为不同的项目，依赖注入的路径不同。

整个项目的目录

这里写图片描述

第一步：先引入需要的jar包

pom.xml

    </dependencies>


    <build>
        <finalName>baseSSH</finalName>
    </build>
</project>

第二步：创建spring，springMvc,mybatis的配置文件

application.xml

<?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"  
     xsi:schemaLocation="http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
     http://www.springframework.org/schema/context 
     http://www.springframework.org/schema/context/spring-context-3.0.xsd">   

     <!-- 引入属性文件 -->
     <context:property-placeholder location="classpath:config.properties" />

     <!-- 自动扫描(自动注入) -->
     <context:component-scan base-package="com.lx.service"></context:component-scan>
</beans>

application-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
            http://www.springframework.org/schema/beans/spring-beans-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/mvc  
            http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

    <!-- 自动扫描controller包下的所有类 使其认为是springMvc的控制器 -->
    <context:component-scan base-package="com.lx.controller" />

    <!-- spring mvc核心配置，spring mvc注解配置 -->
    <mvc:annotation-driven>
        <mvc:message-converters>
            <bean id="jsonConverter"
                class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/html;charset=UTF-8</value> <!-- 避免IE出现下载JSON文件的情况 -->
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>



    <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver"
        p:prefix="/" p:suffix=".ftl" />

    <!-- 上传文件大小限制 还要导jar包commons-fileupload -->
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!--one of the properties available;the maximum upload size in bytes 30M -->
        <property name="defaultEncoding" value="UTF-8" />
        <property name="maxUploadSize" value="32505856" />
    </bean>

</beans>

application-mybatis.xml

<?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:tx="http://www.springframework.org/schema/tx"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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-3.0.xsd">


    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <!-- 基本属性 url、user、password -->
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.user}" />
        <property name="password" value="${jdbc.password}" />

        <!-- 配置初始化大小、最小、最大 -->
        <property name="initialSize" value="${jdbc.initialSize}" />
        <property name="minIdle" value="${jdbc.minIdle}" />
        <property name="maxActive" value="${jdbc.maxActive}" />

        <!-- 配置获取连接等待超时的时间 -->
        <property name="maxWait" value="60000" />

        <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
        <property name="timeBetweenEvictionRunsMillis" value="60000" />

        <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
        <property name="minEvictableIdleTimeMillis" value="300000" />

        <property name="validationQuery" value="SELECT 'x'" />
        <property name="testWhileIdle" value="true" />
        <property name="testOnBorrow" value="false" />
        <property name="testOnReturn" value="false" />

    </bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="typeAliasesPackage" value="com.lx.entity" />
        <property name="mapperLocations">
            <list>
                <value>classpath:mybatis/SQL/*.xml</value>
            </list>
        </property>
    </bean>

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

</beans>

第三步：配置连接Mysql参数

config.properties

jdbc.url=jdbc:mysql://localhost:3306/usertest?useUnicode=true&amp&characterEncoding=UTF-8
jdbc.user=root
jdbc.password=123456
jdbc.initialSize=1
jdbc.minIdle=1
jdbc.maxActive=40

第四部：配置web.xml

web.xml

<?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"

        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:spring/application*.xml</param-value>
    </context-param>

    <!-- 前台向后台提交的时候进行重新编码 -->
    <filter>
        <description>字符集编码</description>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <description>字符集编码</description>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <!-- 前台向后台提交的时候进行重新编码 的映射 -->
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern><!-- 过滤所有地址的请求 -->
    </filter-mapping>

    <!-- spring监听器 -->
    <listener>
        <description>spring监听器</description>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 防止spring内存溢出监听器 -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>

    <!-- spring mvc servlet -->
    <servlet>
        <description>spring mvc servlet</description>
        <servlet-name>springMvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <description>spring mvc 配置文件</description>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:/spring/application-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springMvc</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>/WEB-INF/ftl/index.ftl</welcome-file>
    </welcome-file-list>


    <!-- 配置session超时时间，单位分钟 -->
    <session-config>
        <session-timeout>30</session-timeout>
    </session-config>
</web-app>
