*  2.新建applicationContext.xml文件：  
    2.1任意配置一个bean,然后在测试里面测试看自动注入是否成功【测试spring环境】  
    2.2还可以配置数据库连接配置  
    2.3扫描service事务层  
    2.4配置mybatis相关设置  
    2.5配置事务

测试spring环境：

applicationContext.xml中的具体配置，包含类mybatis的配置如下：

<?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: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
            ">
    
        
        <context:component-scan base-package="cn.itsource.ssm.service" />
    
        
        <context:property-placeholder location="classpath:db.properties" />
    
        
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
            
            <property name="driverClassName" value="${jdbc.driverClassName}" />
            <property name="url" value="${jdbc.url}" />
            <property name="username" value="${jdbc.username}" />
            <property name="password" value="${jdbc.password}" />
            
            <property name="maxActive" value="150" />
            
            <property name="minIdle" value="5" />
            
            <property name="maxIdle" value="20" />
            
            <property name="initialSize" value="30" />
            
            
            <property name="logAbandoned" value="true" />
            
            <property name="removeAbandoned" value="true" />
            
            <property name="removeAbandonedTimeout" value="10" />
            
            <property name="maxWait" value="1000" />
            
            <property name="timeBetweenEvictionRunsMillis" value="10000" />
            
            <property name="numTestsPerEvictionRun" value="10" />
            
            <property name="minEvictableIdleTimeMillis" value="10000" />
            <property name="validationQuery" value="SELECT NOW() FROM DUAL" />
        </bean>
    
    
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
            
            <property name="typeAliasesPackage" value="cn.itsource.ssm.domain,cn.itsource.ssm.query"/>
            
            <property name="mapperLocations" value="classpath*:cn/itsource/ssm/mapper/*.xml" />
        </bean>
        
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            
            <property name="basePackage" value="cn.itsource.ssm.mapper" />
        </bean>
    
        
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource" />
        </bean>
        
        <tx:annotation-driven transaction-manager="transactionManager"/>
    
    
    </beans>

*  3.新建applicationContext-mvc.xml文件【用于配置springmvc】  
    3.1 扫包 扫controller层  
    3.2静态资源放行  
    3.3视图解析器  
    3.4文件上传  
    3.5mvc注解的支持

applicationContext.xml的具体配置如下：

*  搭建springMVC还需要在 web.xml中配置：

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://java.sun.com/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
             version="3.0"
             metadata-complete="false">
    
    
      
      <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext-mvc.xml</param-value>
        </init-param>
        
        <load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
        
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
    
    
      
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
      </context-param>
      
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
    
    
    </web-app>

测试springmvc集成环境：  
![在这里插入图片描述][2018121523114683.png]写一个简单的页面测试，看是否能跳转成功：  
![在这里插入图片描述][20181215231401516.png]测试结果表明springmvc环境搭建成功：

*  4.配置mybatis向配置，在applicationContext.xml中进行  
    【详细见第2步applicationContext.xml中关于 mybatis的配置】
    
    4.1配置applicationContext.xml  
    4.2配置别名  
    4.3配置mapper映射文件（domainMapper.xml）  
    4.4配置mapper接口（domainMapper）
 *  测试mybatis集成：
