    </dependency>

</dependencies>

二，配置Spring

创建Spring配置文件
<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
      http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
      http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">


    <!--配置注解扫描-->
    <context:component-scan base-package="com">
        <!--不扫描Controller的注解类-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

</beans>

三，配置SpringMVC

1，web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <!--配置SpringMVC的核心控制器-->
    <servlet>
          <servlet-name>dispatcherServlet</servlet-name>
          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--在核心控制器中指定SpringMVC配置文件-->

        <init-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>classpath:SpringMVC_WQL.xml</param-value>
          </init-param>

        <!--服务器启动时加载dispatcherServlet-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!--所有请求url交与dispatcherServlet处理-->
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--编码问题，拦截所有请求转换编码格式-->
    <filter>
        <filter-name>characterEncodingFilter</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>

    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

2，SpringMVC配置文件

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

    <!--注解扫描，只扫描Controller-->

    <context:component-scan base-package="com.*">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--配置视图解析器-->
    <bean name="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--静态资源访问-->

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

    <!--MVC驱动-->
    <mvc:annotation-driven/>

</beans>

四，Spring整合SpringMVC

Spring整合SpringMVC的对象管理：
  1. SpringMVC负责Contorlle对象的管理
  2. Spring负责Service，Componet……等除了Contorlle对象的管理
问题：在服务器启动时dispatcherServlet加载了SpringMVC的配置文件，那么除了@Contorlle之外的其他bean注解归Spring管理的是无效的，因为没有被初始化加载
整合的重点：在Tomcat服务器启动时加载Spring配置文件
在web加上这段代码：
<!--配置Spring监听器加载配置文件，默认只加载WEB-INF目录下的Spring配置文件，所有要重新指定路径-->

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
    <!--设置Spring配置文件路径-->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:Spring_WQL.xml</param-value>
</context-param>

五，Spring整合Mybatis框架

将主配置文件由Spring进行管理
<!--整合Mabatis框架-->
<!--配置连接池-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="com.mysql.jdbc.Driver"/>
    <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/wql"/>
    <property name="user" value="root"/>
    <property name="password" value="123"/>
</bean>

<!--配置Mybatis的SqlSessionFactory工厂-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
</bean>

<!--配置AccountDao接口所在的包，扫描Maybatis的从配置文件-->

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

<!--配置Spring的声明式事务-->

<!--配置事务管理器-->

<bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>

<!--配置事务通知-->

<tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager" >
<tx:attributes>
    <tx:method name="find" read-only="true"/>
    <tx:method name="*" isolation="DEFAULT"/>
</tx:attributes>
</tx:advice>

<!--配置AOP增强-->
<aop:config>
    <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.dao.*(..))"/>
</aop:config>
